Description

Habitat for Providing Ecosystem Environment of Fish}

The present invention relates to a habitat for providing an ecosystem of fish, and more particularly, to a habitat suitable for their habitat, such as fish or aquatic ecosystems, which have been destroyed by human activities in freshwater or are deficient. It provides habitats to provide fish ecosystems for stable spawning, hatching, flooding, and tidal currents such as floods and birds, and to provide the optimal habitat for fish. will be.

As the scope of pollution by human beings is gradually expanded along with industrial development, the destruction of the environment is proceeding rapidly, and for this reason, the habitat of wild animals and plants is disappearing or narrowing.

Until recently, the government intends to proceed with projects considering ecological restoration to natural rivers in order to overcome the limitations of the existing river maintenance project, which is centered on the completion and completion of ecological rivers and home rivers. However, the progress of these projects requires more active consideration and consideration of the fish and aquatic organisms that make up the main stream, but there is also no current alternative.

In the river ecosystem, natural conditions without artificial additions are ideal. However, human water use and unavoidable river development alter water quality and stream flow areas, resulting in changes in fish habitat conditions, resulting in changes in river biota.

In the river ecosystem, organisms divided into producers, consumers, and decomposers are divided into habitats composed of inanimate objects such as water, various salts, rocks, stones, sand, and mud. The river ecosystem environment can be divided into land, land and aquatic zones, and aquatic zones. On land, plants, terrestrial insects and algae are inhabited, and aquatic zones are attached to algae, aquatic insects and fish. In addition, a variety of other plants and animals live on the borders between aquatic life and land. Restoration of habitat conditions for these various organisms can be initiated by creating the habitats required by each organism to inhabit not only fish but also aquatic life including amphibians and benthic species. .

In particular, because fish, which are representative species of the river environment in the ecosystem and are also used as biological indicator species for water quality determination, operate in extremely limited waters unlike other wild animals, changes in habitat, ie, changes in flow rate, can affect their survival. Has a direct impact. Aquatic invertebrates and other microflora are also closely related to fish habitat and the time and space characteristics of rivers, which allows indirect consideration of river ecosystem habitats by focusing on fish and examining their habitats.

River flora and fauna, including fish, require a range of habitat environments for survival and reproduction. In the stream ecosystems, fish habitats are divided into two categories: the bottom of the river and the stream flow area formed by the water itself and the flow rate, and the relationship between the flora and fauna of the stream, that is, the ecosystem structure and interaction. Of particular interest in the development and maintenance of rivers are fish habitats such as the distribution of bed materials necessary to secure water quality conditions, including food depths, hides, etc., including depth, flow rate, water temperature, turbidity, and pollution in terms of flow rate. Habitat Physical conditions that are based on the environment. If natural streams are artificially altered, these physical conditions change accordingly, which means a change in the habitat environment of the river flora and fauna.

It is necessary to create habitats that reflect the heterogeneity of fish habitat in different stream ecosystems, the stages of growth of fish species, and ecological habitat characteristics such as food intake and predation or interaction.

In general, fish have a seasonality for growth stages in the Fish Year with a Diel Behavioral Pattern. The water temperature and water quality for protecting fish habitats should consider not only the daily cycle but also the monthly or seasonal changes, and the most important in creating the fish habitat environment is the temporal and temporal change of water temperature and dissolved oxygen.

In addition, for fish to survive, habitat should be provided to provide adequate depth, space for feeding and living, spawning and hatching spaces, and hiding places for rest and refuge. In order to provide such habitats, the stream itself requires an appropriate flow area through the configuration and shape of the channel which is formed for fish habitat. However, there are many practical difficulties in identifying and identifying the individual characteristics and interrelationships of all species living in ecosystems. Therefore, in order to provide a suitable environment for all river ecosystems, it is possible to predict and cope with changes in the river development and habitat environment in advance by selecting and managing representative fishes for fish that are commonly encountered and easily understood. In this way, river ecosystems can be preserved to the extent possible.

The following describes briefly the types of fish species, classification of fish and habitat environment, habitat requirements and habitat conditions for fish.

1. Selection of fish species

Representative fish species considering the habitat of fish may be selected single fish species or fish family. It is common for fish species to be adopted in accordance with social fisheries concerns, river environment management, and availability of habitat simulation data.

The fish management aspect can be classified into endangered species, recreational or commercial fish species, or fish species for food supply such as fish and birds according to their preferences. In particular, high social and symbolic species, high environmental indicators that require specific environmental conditions, indicator species that take into account the importance of fish communities, rare species to maintain social interest due to high risk of extinction, or food chains. Has a significant profile and can be selected based on species that require a large habitat.

River environmental management can be divided into freshwater, reservoir and freshwater, and complete reservoirs according to the segregation of river fish. In freshwater areas, the species may be applied to the main streams, pools, side channels, meandering channels, vortex sections, or drainage sections. Fish groups are clusters of species with the same class of environmental resources, and can generally provide habitat information that has a wider topographical space than a single species.

[Table 1] below is a list of representative fish species and surrogate fish species in Korea.

2. Classification of fish and habitat environment

Once the target species have been selected, the criteria for fish species should be classified to reflect changes in habitat use patterns. The most common categories are the size, age, or growth stage of the individual. In addition, the extent of habitat use can be categorized according to seasonal or circadian variation, activity patterns, species relevance, water quality characteristics, or sampling equipment.

Fish activities are affected by seasonal and daily changes. Representative examples are activities such as fish migration, habitat use, spawning, growth, and hibernation. In order to evaluate this concretely, it is necessary to consider seasonal variability. Habitat assessment for migration can be based on depth and flow rate for fish passing. However, fish activities such as habitat prep, spawning, and hatching should take into account seasonal or daily changes, and the simplest classification is when the fish are divided into active summer and hibernating winter.

Changes in flow rates in stream ecosystems have a major impact not only on fish, but also on all living organisms in the stream. Among them, the changes in the flow rate are severely affected by habitat, spawning ground and spawning eggs. Therefore, it is necessary to select the water level considering the fish ecology, but considering the fish in the rivers of all species is due to various practical factors such as the lack of basic research on fish, the lack of research that fully considers all ecosystems, and the time and expense. Difficulties will arise. Therefore, by selecting and managing representative fish species that are commonly encountered and easily understood, we should predict and cope with changes in the river development and habitat environment of the water system so that the river ecosystem can be preserved to the extent possible.

3. Habitat Requirements for Fish

In the freshwater ecosystem, which is divided into two types of water purification and freshwater ecosystems, the streams belonging to the freshwater ecosystem have a wide variety of ecosystem habitat conditions depending on the nature of the water bodies and the state of the water quality. These habitat conditions are closely related to the habitat requirements of the waters living in the water. Each fish has different habitat conditions depending on the population. The following representative species will have unique habitat conditions.

The representative fishes in Table 2 are generally spawned in shallow shoals, and are attached to shrees, stilts, tangles, sand-scattered sands, yams, sacks, and stones that settle between the gravel and between the stones. It can be divided into stony, sack that is attached to cracks of stone, herds that are attached to plants, and ropes and leads that are scattered in freshwater shells.
In addition, most of the representative fishes spawn in July-October, and the growing season is from April to November when the water temperature is maintained above 10 ℃, and it is known to enter hibernation in November-March when the water temperature falls below 10 ℃. . The hibernating places are relatively slow and deep ponds, rock formations between rocks, between stones, between grasses and sand, depending on the species.
Most representative fish species adapt to the water quality of the second grade, including the hawks and shoals that adapt to the third grade. In the case of dissolved oxygen, at least 5ppm for bran, shuri, tongari, sesame, sakoff columbine, pearfish, stone shark, pyramid, stonefish, stony, sand, thigh, yam, and more than 3ppm In case of molar or push, it inhabits more than 2.5ppm. Most fish species can be inhabited with biological oxygen demands of 2 to 5 ppm, and even at 2 to 10 ppm, which are slightly more organically contaminated.
For the preferred depth, the crab, shree, stone tuna sparrow, and sakoff are 20 to 50 cm, the fur, 30 to 50 cm, sand, and 20 to 80 cm, the tong is 30 to 50 cm 30 ~ 100cm, yam 50 ~ 80cm, and rope and lead stalk 30 ~ 120cm.
In terms of flow rate, most representative species prefer water bodies that maintain strong streams of about 30 to 80 cm / sec, and seals, stony, push, ropes, yams, and napkins prefer rather slow bodies.

4. Habitat Conditions

3 is a view showing the turbidity blocking gate 125 according to an embodiment of the present invention.

1 and 3, when the internal water level of the main body 105 in which the multistage ecological reef 115 is installed reaches a preset height B, the turbidity blocking gate 125 is introduced into the main body 105. Can block turbidity. For example, the turbidity blocking sluice 125 may block at least one porosity 110 to block the turbidity from flowing into the body 105.

In more detail, in an emergency such as a flood or in an emergency, the flow rate of the river is increased and the water level is rapidly increased, which causes turbidity to flow. In this case, a small amount or a large amount of turbidity flows into the main body 105 of the first habitation 100, and the turbidity blocking gate 125 can block the inflow of turbidity when the water level reaches a preset height B. have. As a result, the turbidity flowing into the main body 105 may be blocked, and the fish in the first habitation 100 may stay in a relatively good water quality compared to an external environment such as a river. In addition, the turbidity blocking sluice 125 may have a height B that is set in advance in order to provide the time required for the fish in the mainstream section, that is, the fish outside the main body 105 to evacuate to the main body 105. Wait for to reach and block the flow of turbidity.

Referring to FIG. 3, the turbidity blocking gate 125 includes guides 31, a floating gate 32, a buoyancy body 33, and stoppers 34.

The guides 31 are provided parallel to each other on one surface of the main body 105.

If the normal level (A) that is normally maintained is increased due to reasons such as flood inflows, the flotation gate 32 will not rise until the level rises within a certain range (i.e., to a preset height B). Is configured to not work). That is, the floating gate 32 is the buoyancy body 33 installed on the upper portion of the floating gate 32 when the internal water level of the main body 105 reaches the preset height B while maintaining the normal water level (A) or less. By rising along the guides to the operation stop water level (C) to close at least one pore 110. As a result, the turbidity blocking gate 125 may block the turbidity flowing through the at least one pore 110.

In particular, a plurality of turbidity blocking layers 41, 42, and 43 are formed in the floating gate 32, and the number of the turbidity blocking layers 41, 42, and 43 is the same as the number of layers of the pore 110. The size of each turbidity blocking layer 41, 42, 43 may be greater than or equal to the size of the pore words 11, 12, 13 corresponding to each other. In detail, when the floating gate 32 rises to the movable stop level C, the turbidity blocking layer 41 faces the pore 11 and the turbidity blocking layer 42 faces the pore 12. The turbidity blocking layer 43 is opposed to the pore fish 13. Thus, for example, the size of the turbidity blocking layer 41 is formed larger than the porehole 11 corresponding to the turbidity blocking layer 41, so that when the floating gate 32 rises, it flows into the porehole 11. The turbidity can be completely blocked.

The buoyancy body 33 is provided perpendicular to the guides 31 and is located at a height that coincides with a preset height B of the floating gate 32. Therefore, when the internal water level of the main body 105 reaches the preset height B, the internal water level of the main body 105 also coincides with the height at which the buoyancy body 33 is provided, and consequently the floating gate 32 ) Is raised by the buoyancy body 33, that is, by the buoyancy due to the level rise. As a result, the flotation gate 32 may automatically rise to block inflow of turbidity even when a separate power supply means is not provided.

The stoppers 34 are attached to the upper portions of the guides 31, respectively, so that the floating gate 32 rises to the movable stop level C, which is the height at which the stoppers 34 are located. That is, even when the water level rises above the operation stop water level C, the floating gate 32 can stop the rising operation without further rising by the stoppers 34.

4A to 4C are diagrams illustrating the turbidity blocking gate 125 according to another embodiment of the present invention.

The role of the turbidity blocking gate 125 shown in FIGS. 4A to 4C is the same as that of the turbidity blocking gate 125 described with reference to FIG. 3. That is, the turbidity blocking sluice 125 shown in FIGS. 4A to 4C enters the main body 105 when the internal water level of the main body 105 in which the multi-stage ecological fish pond 115 is installed reaches a preset height B. Can block the turbidity. Therefore, a detailed description of the role of the turbidity blocking gate 125 of FIG. 4A is omitted.

Guides 51 are provided in parallel in the direction from the ceiling of the main body 105 toward the bottom. That is, the guides 51 are fixed to the ceiling of the body 105 to be suspended.

One side of the floating gate 52 is connected by the ceiling of the main body 105 and the connecting parts (53, 54, 55, 56), the other side is fixed to the top of the at least one pore (11, 12, 13) . The connections 53, 54, 55, 56 can be connected to the ceiling, for example by means of a pulley 59.

When the main body 105 is viewed from the side as shown in Figure 4b, the floating gate 52 is provided between the at least one pore 110 and the guides 51, at least one pore 110 or 11, 12 and 13, the same number of blocking films 52a, 52b, and 52c are included. When the water level inside the main body 105 maintains the normal water level A, the blocking films 52a, 52b, and 52c are provided in a fixed form on the corresponding pore words 11, 12, and 13, respectively. In this case, the blocking films 52a, 52b, and 52c connected to the connection parts 54, 55, and 56 may be substantially parallel to the bottom of the main body 105 as shown in FIG. 4B.

Both sides of the buoyancy body 57 is connected to the guides 51, whereby the buoyancy body 57 is installed to be fixed between the guides.

When the water level inside the main body 105 reaches the preset height B and the buoyancy body 57 moves to the movable stop water level C, the blocking film of the floating gate 52 is moved by the movement of the buoyancy body 57. The fields 52a, 52b, and 52c descend to the lower portions of the pores 11, 12 and 13, respectively, to block the inflow of turbidity by closing the pores 11, 12 and 13, respectively. That is, when the buoyancy body 57 rises to the movable stop water level (C), the length of the connection portion 53 connected to the pulley 59 and the buoyancy body 57 is shortened and the other connection portions 54, 55, 56 are separated. The length is increased. As a result, the blocking films 52a, 52b, and 52c connected to the connecting portions 54, 55, and 56 are folded in a state substantially perpendicular to the bottom of the main body 105 as shown in FIG. 11, 12, 13) will be closed.

On the other hand, when the fish present in the first habitat 100, that is, the biomass increases, the consumption of oxygen is increased, the concentration of dissolved oxygen compared to the outside of the first habitat 100 may be lowered. Therefore, in order to prevent such a problem in advance, the embodiment of the present invention can artificially form the flow of water for the attraction and habitat of fish, for this purpose is provided with an internal circulation facility 130 and an external circulation facility 135 can do.

The second habitat 200 provides a habitat that is more suitable for species that prefer a relatively deep depth or species that prefer a center of water.

According to the embodiment of the present invention described above, as a means for restoring the ecological function of the aquatic ecosystem to form a habitat in the water to satisfy the appropriate growth conditions of the fish. This is because aquatic organisms and other micro-animals have deep relations with fish habitat conditions, and because of the fish habitat conditions, the habitat environment of other organisms is also indirectly considered. According to an embodiment of the present invention, a habitat installed in a water body may serve as a spawning ground for aquatic fish and aquatic organisms, and may be a resting place to avoid direct sunlight such as strong sunlight, and as a shelter from predators such as birds and large fishes. Can play a role.

Third, according to the embodiment of the present invention, by limiting the size of the inlet of the habitat can be configured to enable protection from natural enemies and predators of fish. In other words, by limiting the size of the entrance to the fish to a predefined size, it is possible to create a habitat that is safe for aquatic life in the habitat by limiting the large predator to enter the habitat.

Fourth, according to an embodiment of the present invention, it is possible to select the location of the habitat in consideration of the habitat preference environment of the target organism. In detail, for species that prefer deeper depths and centers relative to other species, target organisms set up habitats in the form of riverbeds, and for species that prefer relatively shallower depths and edges, the habitats may By installing in the form, various forms of habitat can be configured according to the target fish species. In addition, when applying this habitat, the habitat can be applied in various ways depending on the site conditions, and can be formed directly or independently of the water body, or can be used in conjunction with the fishery or pipeline.

Fifth, the habitat according to the embodiment of the present invention has a structure that allows sunlight to be directly irradiated into the habitat. This is because aquatic organisms and aquatic plants require some amount of sunlight irradiation to survive. In addition, if necessary, it may be equipped with a mining facility so that the sunlight can be directly irradiated into the habitat in order to have a similar environment inside and outside the habitat. In this case, the direct light is irradiated to the inside of the habitat in the form of indirect mining instead of the strong direct sunlight, and thus, the environment preferred by the fish inhabiting the habitat can be created.

In addition, according to an embodiment of the present invention, it is possible to provide an environment-friendly facility by configuring the solar power generation as a power source such as oxygen supply or observation facilities.

The present invention is used as a means to secure habitats for which most of the installation targets are lacking due to anthropogenic activities, but the places where the installation area is easily accessible to residents, such as hydrophilic spaces, emphasize the necessity of the current status of aquatic ecosystems and fish protection. Of course, it can be installed together with educational, experience facilities and observation facilities.
