Description

1280849 V. INSTRUCTIONS (1) ' [Technical Field to Which the Invention Is Applicable] 1 The present invention relates to a device for utilizing a bio-sexuality of an aquatic crustacean for a specific light-dark contrast to guide its movement The method of trending water. The device produces a specific contrast between light and dark contrasts on a particular area of the aquatic body in which the aquatic crustaceans are located, and acts to attract aquatic crustaceans to move closer. The required aquaculture or direct use of the land and the use of the land industry, and 5, 961 points in the production system of the land resources are also related to the output of the cultured organisms are usually more predatory. Neck 0 [Prior Art] Aquatic crustaceans contain a variety of cultures that are often re-used using artificial culture methods. Many countries have already invested in large-scale aquaculture development into a viable way that inevitably consumes a large number of near-high-density farming systems before being used in high-density farming systems by 4, 3 68, 6 9 1 and 4, 446, 0 2 5 Special facilities can be used to reduce the damage of water and soil environment. These high densities yield higher yields and profits, but the resulting increase in residual rate is due to the lack of clam shells or larger individual densities in the clam shells or younger clam shells at different physiological stages. Bottles of economically farmed animals that increase the efficiency of farming. People get this kind of life in the natural environment, and hope to model the people of these creatures. Traditional artificial farming costs such as water resources. Until most as disclosed in U.S. Patent No. 8,31. These water recycling equipment includes filtration consumption and reduced use for nature, although it can be created because of increased density of culture. These losses in production are caused by mutual attacks, for example, the vulnerability to being located in the same culture water.

Page 7 1280849 V. INSTRUCTIONS (2) Therefore, the management of behaviors to avoid the occurrence of residual food has become an important issue for the successful application of high-density culture systems in the cultivation of aquatic clams. For the purpose of this management, crustaceans that spatially separate the clam-shell stage from the non-clam shell stage are viable means of avoiding the occurrence of residual food. So far, some related technologies have been exposed. For example, traditional culture ponds use passive water and space to passively reduce the chance of contact between clam shell culture and clam-free culture. In addition, scent or sensation And chemical attractants have also been used to manage the occurrence of clam shell feeding, mating and oviposition (US Patent 5,7 0 6,7 5 9 reveals a chemical stimulator, chemistry for shrimps). A method of repelling or chemically attracting); in addition, U.S. Patent 4,8 2 8,8 2 9 discloses an attractant liquid which can enhance the efficiency of crab capture, such as fish oil, U.S. Patent 5, 2 5 9,8 0 9 Use a food trap to collect and capture shrimp by collecting plankton or similar other shrimp food. However, these technologies and inventions still lack the practical solutions that can be applied to the management of shrimp behavior in high-density culture ponds. Any other known technique within the scope of the knowledge does not use the method of clamshell organisms to effectively manage its behavior by contrasting the characteristics of light and dark contrast. Due to the current lack of appropriate techniques for the effective management of aquatic crustaceans at high aquaculture densities, the management of aquaculture density is often limited to the extent that no significant residual food is caused. The traditional culture pond height of shrimps must usually be maintained between 0.6 and 2.0 meters, so that the shrimps of the clam shells can jump upwards or backwards and escape from other non-clam shell cultures, thereby reducing the occurrence of residual food. Probability. With a height of 0.6.

1280849 V. INSTRUCTIONS (3) To a 2.0 m aquaculture water body, due to its excessive weight and volume, it is difficult to implement a multi-layered farming system, so that the traditional traditional shrimp farming method is limited to a flat Architecture. In other fields, such as laboratory requirements, it is not possible to supply healthy clams in a convenient culture under standard conditions as research materials. Markets or restaurants need to raise aquaculture clams in dense display spaces. Management of aquatic crustaceans and the inability to effectively display live aquatic clams as expected. In the natural state, many aquatic clams, such as shrimps, grow in a water environment with alternating light and dark contrasting contrast effects. The light and shadow effects of alternating light and dark contrasts show shadows or fissures, rather than flat areas. Reflected wave light. Aquatic clams can use these light effects to calibrate possible hiding locations. Once the aquatic crustacean arrives at the site, the animal will use other senses to determine if the site is an actual hiding place or to continue exploring other possible hiding locations. The above-mentioned aquatic crustaceans have a clear characteristic of the contrast of light and dark light contrast, and the utilization of this characteristic can develop a feasible method for managing the movement or localization of aquatic crustaceans, and the core of the present invention is the above-mentioned organism. Contemplating and conceiving, and the biological tropism for contrasting light and dark light can also be found in other organisms such as insects and the like. However, in the currently known technology, no concept similar to the technique of the present invention has been disclosed to guide aquatic crustacean activities. [Summary of the Invention]

1280849 V. INSTRUCTIONS (4) A dynamic or static source of light that is directly illuminated, or reflected, or filtered to create a specific contrast between light and dark can be used to attract aquatic crustaceans to a specific area. This position, which can be seen by an aquatic crustacean, is the location of a particular region defined above. The complete details of designing a particular area to attract clam shells should actually include two steps. The first line attracts clam shells to actively move closer to or into this particular area, and the second is to induce attractive crustaceans. The actual hiding behavior of the creature. The present invention is only related to the first step, and in particular, the behavior of searching for a hiding place in the first step can be affected by the artificial light and shadow effect. The second stage of the steps involves the establishment of a suitable tactile or other sensation in a particular area, including the arrangement of a particular environment, and this portion is not included in the scope of the present invention. As stated above, it is an object of the present invention to provide a device that can direct the movement of aquatic crustaceans. The device is used in a method that attracts aquatic crustaceans that are prone to hunger before satiety and seeks to hide or stay.

Such devices, devices or means for producing a contrasting effect may be directly installed in a specific area as described above, or near the surface of the water, or even on the outside of the bottom of the container, as long as it can be formed in a specific area to be acceptable for aquatic crustaceans. Light and dark contrast effect. The apparatus, apparatus, or means for producing such a contrasting effect may include one or more incandescent or fluorescent bulbs, or light emitting diodes, or/and one or more filter sets, and may also include one Or a plurality of protrusions that can produce a shadow, or a combination of one or more color blocks. If the device does not contain a source of illumination, additional lighting may be included as an additional facility. The above filter set is a structure having two or more transmittances between 0% and 100%. The filter used in the present invention is an extreme example of the structure of the filter set: the transmittance of the filter portion is 100%, and the transmittance of the filter body portion is 0%.

The method can be applied to many fields, such as aquaculture and agriculture, including capture and concentration for feeding or harvesting purposes, and management for display purposes. [Embodiment] The present invention provides an aquatic clam shell that can be used to guide hunger after satiety.

1280849_ V. INSTRUCTIONS (7) 'A device for the animal's movement trend method. The foregoing method includes a step of producing a contrast-visible effect on a specific region of a water body, which is described in the application of the π-species using aquatic crustaceans for specific light-dark contrast responses in August 30, 2004. Application Part No. 1 0 / 9 2 9, 9 0 1 (Taiwan application for 2 0) The application filed on October 28, 2008, file number 0 93 1 32 748), which is hereby incorporated by reference. The method of attracting an aquatic crustacean that is hungry before hunger to seek hiding or indwelling includes a step of producing a contrasting effect on a particular area of the body of water. The above specific area can be distinguished by one or more first luminance sub-regions and one or more second luminance sub-regions due to the effect of light and dark contrast. The present invention provides a device for attracting aquatic crustaceans to move to a specific area for seeking to hide or stay, comprising a container for aquaculture water, and a specific area in the container that exhibits contrast between light and dark contrast . The above-mentioned specific area is an area in which a light-dark contrast effect is exhibited in a body of aquatic crustaceans. This area can be selected from any area between the bottom of the container, the wall, or the bottom and the culture surface, and the effect of light and dark contrast can be generated, scattered or projected onto the fixture or drift in any of the above areas. . A device for producing such a contrast between light and dark, that is, one or more of the aforementioned light source bodies, or a combination of reflectors such as one or more color blocks, and

Page 13 1280849_ V. INSTRUCTIONS (8) '/or one or more sets of protrusions, in addition, filter sets with one or more fixed-filters may also be used. The light source, the light reflection source or the filter device which produces the light and dark contrast effect can be directly installed in the specific region, or near the water surface, or even on the outer side of the bottom of the container, as long as it can be formed, projected, scattered, and / or coating a light and dark contrast effect acceptable for aquatic clams. The specific area described above can be distinguished by one or more first luminance sub-regions and one or more second luminance sub-regions due to the contrast effect produced by the above device. Wherein, the first brightness sub-region is brighter than the second brightness sub-region. The so-called contrast between light and dark refers to the contrast between the first luminance sub-region and the second luminance sub-region adjacent or close to it. · The size and depth of containers for aquaculture waters may vary depending on the type and size of the actual aquatic clam shell organisms, and there are no specific specifications. For example, white shrimp (scientific name Litopenaeus vannamei) can be cultured in water bodies of 10 cm depth. Compared to the traditional blue shrimp (scientific name Penaeus setiferus), white shrimp (scientific name Litopenaeus vannamei), tiger shrimp (scientific name Penaeus monodon) and spotted shrimp (scientific name Panaeus japonicus) used in the culture of 60 cm to 200 cm water depth In terms of the gap, there are many differences. The first luminance sub-region and the second luminance sub-region may be arranged regularly or irregularly, occurring synchronously or asynchronously. Adjusting the position and angle of the light reflecting device or the filtering device (such as the above-mentioned coated color block combination, protrusion and filter, light film) and/or coexisting illumination source, or changing the combination of the light source, can change Brightness of a luminance sub-region and a second luminance sub-region

Page 14 1280849_ V. Description of invention (9) and shape. In addition, the shape, arrangement and reflection range of the coated patches and the properties of the filter can be designed or adjusted depending on the brightness of the predetermined first and second brightness sub-regions. The brightness of the first brightness sub-region and the second brightness sub-region may vary or remain fixed. When all of the first luminance sub-regions or all of the second luminance sub-regions have more than one number, it is not necessary to have the same luminance at the same time. The contrast between light and dark can be directly from a source of illumination (see Figures 2a and 2b), or by a filter (see Figure 3), or a coated patch that reflects light (see Figure 1) and highlights that reflect light. The combination of bodies (see Figures 4 and 5) is produced. When an illuminant such as a light-emitting diode, an incandescent light bulb, or a fluorescent light bulb is selected for use, it can be directly used to form a light-emitting source of a light-dark contrast effect, and can be directly disposed in a specific area. Single or multiple illuminants, the same or different brightness, can be used to create a contrast between light and dark. The above-mentioned light-dark contrast effect can be produced by the opening or closing of the illuminator itself, the difference in brightness of the illuminator itself, and the illuminated area and the darker area. The preferred embodiment employs a plurality of illuminators, as shown in Figures 2a and 2b, which effectively produce a contrast between light and dark through the opening and closing of the light source. However, if it is considered that the repeated activation and shutdown is likely to cause loss of the illuminant, a illuminant group of a sparsely arranged continuation can also be selected. The aforementioned sparsely arranged light source group may be composed of a plurality of individual illuminants, or may be composed of a plurality of complex illuminant clusters. Alternatively, turning one or more of the illuminants on and off may flash in a synchronized, staggered, or asynchronous manner. As is well known in the art, a light transmissive structure or material can be used for cladding

Description of the invention (ίο) in the illuminant to prevent the use of a light reflection in the aquaculture water body and the reflection of the color block shaded protrusions are used. Directly from the illuminating source, the second region and the second bright shape, hexagonal shape or its array, circle shape, illuminating filter, blistering or illuminating diode to reach the position of the illuminating sheet of 1 to 300 illuminance, In this way, the combination pattern of the bright spots can be the first effect of the shell-like touch and adhesion by the illumination light passing through and the darker regions. The coated color block is placed in the specific area, evenly or gradually brightened

The occurrence of influent water (not shown in the figure). The device or filter set should have an internal or external illumination source attached. For example, when a flat region is coated in FIG. 1 or a reflected light shape in FIGS. 4 and 5, or a filter having different transmittances thereon, or a light guide sheet or a light reflection source. The shape of the first luminance sub-region formed may be linear, square, rounded or non-geometric, and it may be arranged in a grid or other regular and irregular shape. The illumination source for the cloth color block or the protrusion can be a commercially available lamp, and the illumination can be in the water or water body (1 ux) under normal conditions. A shadow is formed on the bottom of the container after passing through the aquaculture water body from the area between the bottom of the container and the illumination source (shown in Figure 3). In a preferred embodiment, the surface is placed on the surface of the aquaculture water body to provide a structure for providing the nourishment and retention or hiding. The brighter region, that is, the second luminance sub-region formed by the high transmittance opening, that is, the illumination light is blocked or passes through the low transmittance portion of the luminance sub-region, and the two together form a light-dark contrast and filter The pattern formed by the sheet or the protrusion may be directly distributed, and the periphery of the specific area may be further increased in degree to increase the attraction effect established in the specific area.

INSTRUCTION DESCRIPTION (11) The aquatic clamaceous organisms of the present invention include, but are not limited to, shrimp or prawn 'where white shrimp (scientific name Litopenaeus vannamei), tiger shrimp (scientific name Penaeus monodon), blue shrimp ( The scientific name Penaeus setiferus) and the spotted shrimp (scientific name Panaeus japonicus) are preferred breeding objects. In one embodiment, the cultured organism is white peony (literal name Litopenaeus vannamei), the water depth is 1 〇 cm, and the filter is filtered. The sheet has openings of the same size or different sizes that are 0 to 2 to 2 cm in length. The filter is placed between 4 and 9 cm below the surface of the water. A fluorescent lamp that can reach 1 〇 to 60 illuminance (1 ux) at the surface of the water is used to illuminate the filter under the surface of the water. sheet. When the light reaches the filter, a portion of the light will pass through the hole in it and a portion of the light will be blocked by the portion of the filter that has no opening. The effect of the dark contrast is also produced. In the case of white shrimp, the contrast between the first brightness sub-region with brightness of 'Μ illuminance and the second brightness sub-region with brightness of 5 illuminance can effectively work, that is, after satiety ^ = same The size of the white shrimp (〇· 05 to 40 g) will be effectively attracted to the area of the 1^ area. In addition, 30 minutes after the feeding, a large number of shrimps will be hidden in the filter of the appropriate configuration. Chip. ^ ί The device for forming the contrast between light and dark is illustrated in Figures 1 to 5 and explained one by one in the following examples. ΐ f: In the example, see Figure 1, the strip made of paint or tape & the grid pattern i 丨0 combined by the t-pattern is applied to the bottom of the container - specific Area 130. The dark blocks in the specific area 13〇 and the uncoated blocks 131 each form the aforementioned second brightness

1280849 V. INSTRUCTIONS (12) The region and the first brightness sub-region 5 and the underside of the Zhaoming light source 1^0 form a light-dark contrast effect. The specific region in the container is made of light-transmitting material. The coated color block is also a light transmissive material. At this time, the light source can be constructed under the container, and the coated color block placed in the specific area or on the outer side thereof is projected from the lower white surface. To form the effect of light and dark contrast. That is, when the container is permeable to light by the portion of the illumination source m, the illumination source is placed at any position where it can be projected onto the combination of geometric or non-geometric tiles having different brightness. In the second embodiment, as shown in Fig. 2a, a combination of arrays formed by a plurality of illuminants 2] L0a is a direct source of contrast between light and dark. The aforementioned illuminant 21 'Oa may be a fluorescent diode incandescent incandescent Lamps or other light sources 0 Light-emitting diodes are based on economic considerations. This is a better choice. If you consider the low cost and convenience of fluorescent lamps, fluorescent lamps are also a better choice. 2] The array formed by L Oa is arranged at the bottom 201a of the container 2 0 0a, and the specific area 230a can thus distinguish a plurality of less bright sub-areas 23 2a, that is, the second brightness sub-area j and the brighter The area 231a, that is, the first brightness sub-area, the illuminant can be continuously or alternately bright, j, and the brightness can be maintained fixed or varied. Based on the convenience of the device and the control, this embodiment adopts a set of continuous illumination and is whitened by each The illuminating source formed by the individual illuminating diodes is combined into a light source 〇 in the third embodiment. Referring to Fig. 2b, a combination of array forms formed by a plurality of illuminants 2 1 0 b is a direct source of contrast between light and dark. 〇 The aforementioned illuminant 21 • 0 b can be a light-emitting diode Λ a fluorescent incandescent lamp or other light source. The light-emitting diode is based on the durability economy and is preferred here.

Page 18 1280849 V. INSTRUCTIONS (13) Fluorescent lamps are also a good choice for measuring the low price and convenience of fluorescent lamps. An array of illuminants 2 1 0 b formed, which is not arranged at the bottom of the container 2 0 0 b 2 0 1 b as shown in Figure 2a, but is arranged above the aquaculture water in the container 2 0 0 b, a specific area 2 3 0 b is irradiated by the array of the illuminants 2 1 0 b, so that a plurality of less bright sub-regions 2 3 2 b, that is, the second luminance sub-region, and the brighter sub-region 2 3 1 can be distinguished. b, the first brightness sub-region. The illuminator can be illuminated in a continuous or alternating manner, and its brightness can be maintained fixed or varied. Based on the convenience of the device and the control, the present embodiment employs a set of continuous illumination and a combination of the respective individual light-emitting diodes as the illumination source. In another embodiment, similar to the embodiments 2 and 3, when the container When the portion illuminated by the illumination source has a light transmissive property, the illumination source is the device that can be irradiated to any position on the specific region. It is not limited to being located above or below the container. In the fourth embodiment, as shown in FIG. 3, a filter having a hole 31 is used to filter the light of the illumination source 3 2 0, and the filter 3 1 0 has a light transmission through the hole 3 1 1 . The degree is 100%, and the transmittance around the area around the hole 3 11 is 0%. A plurality of light beams 340 are formed by the illumination source and the filter, and thus simultaneously produce a plurality of illuminated sub-regions 3 3 1, ie, a first measurement sub-region, and a sub-region 3 3 2 that is not illuminated, That is, the second measurement sub-region, the two sub-regions together form a light-dark contrast effect in a specific region 3 3 0 of the bottom portion 3 0 1 of the container 300. The filter 3 10 can be an opaque circular filter placed horizontally and formed of a PVC-like material, and the shape, material and position angle are not circular.

Page 19 1280849__ V. INSTRUCTIONS (14) ‘PVC and level are limited. Other shapes, materials, and locations suitable for producing such expected light and dark effects can be used, such as quartz, acrylic, glass, or other materials that can be used as the filter 310. The shape of the hole 3 1 1 is not limited to a circle, and the size of the hole 3 1 1 may be between 0.1 to 8 cm each of the same or differently different, and the hole 3 1 of 0.1 to 8 cm. A grid distance has also been confirmed to be valid. Although the light transmittance of the hole 31 1 1 of the filter 3 10 in this embodiment is 100%, materials or structures having different transmittances may be used. At the same time, the light transmittance of the filter itself can also be adjusted. The position of the filter 3 10 is set between the bottom portion 310 and the illumination source 3 2 0 , which may be located above the water surface or into the aquaculture water contained in the container 300. When the filter enters the water 2 to 9 cm, it not only can effectively attract the white shrimp after satiety, but also proves to be used to provide tactile sensation and promote the white shrimp and blue shrimp in a specific area of 3 3 0 in light and dark contrast. The hiding behavior. This type of arrangement is more suitable for use in the case where the container is constructed of an opaque material. When the container is constructed of a light transmissive material, the filter is still located between the illumination source and the particular area, but the illumination source does not have to be located above the container. For example, an illumination source can be disposed under a container having a transparent bottom, and a filter positioned at a specific position on the illumination source is irradiated from above, and a pattern arranged by light and dark contrast can be Under this configuration, a specific area within the container is produced. In all embodiments employing a filter, such as Embodiment 4 and the like, the arrangement angle of the filter can be adjusted.

The protruding structure 4 10 is formed by interlacing a thin wall lithographic pattern on a specific region 430 of the bottom portion 40 of the container 400. The height of the mesh-like protruding structure 41 0 is between 0.1 and 8 cm, and the distance between adjacent two protruding lithographs is between 0 · 1 and 8 cm. When an illumination light source 420 is irradiated to the mesh-like protruding structure 4 1 0 at an oblique angle, the effect of contrast of light and dark light can be effectively formed. The height and distance between the above-mentioned protruding sheets can be adjusted according to the type and size of the culture body and/or the angle of the illumination source. The mesh-like protruding structure 410 forms a shadow under the oblique illumination of the illumination source 410, which thus forms a dark sub-region 4 3 2, ie a second luminance sub-region, and an illuminated sub-region 4 3 1, ie first The sub-area of brightness combines the effect of light and dark contrast. This embodiment has the additional advantage that it additionally provides a shelter that promotes the attraction of the clam shells to hiding or staying in a particular area 304. The sixth embodiment is another modification of the present invention.

The illumination is particularly small in the present invention and the culture area and the bottom surface of the container to reduce the residual food. The machine is wound around a specific area within the specific area of the specific area or the gradual brightness of the area. Through the method of the invention, the culture tank of the fruit is maintained at an arbitrary position of the embodiment of the fifth culture and/or illumination source of the south of the culture and/or the illumination source, when the light-emitting property is emitted, the source of the illumination The position is not limited to being in the tolerance zone, and its range may be determined according to the size of the device. A preferred product ratio is 1 to 1, which occurs at an experimental rate. Therefore, in the upper part, there is a further way. At this point, it may be facilitated to provide means for retreating from the particular area for the purpose of seeking a stay or dodge, and the foregoing is for an embodiment having at least one specific zone angle plus illumination for illumination onto the special device. The actual arrangement is a clamshell, and then stays to adjust the light source to a certain area. In the case of species, it is a proportion of the case that presents a crustacean such that the specific area of the 蜕 is set to pass through. This type can be displayed with a large specific area, and the brightness can be moved to the circumference of the shell state domain. Therefore, the multilayer is low and becomes a viable colonization system. The implementation of the multi-layered area can be in the density of the cultivation. Aquaculture system. In the case of the production of aquatic A. sinensis, the concept of the residual density of the cultivating density is the depth of the system. The concept of the residual food can be caused by the shell or other units of the soil. The reference uses the domain to show that the 10 cm rate is still used for each layer of water animals. The result is that the culture tank is equal to the height of the light and dark contrast in the case. Reduced, multi-layered nutrient efficiency. Shown in Table 1.
