Abstract

The present invention includes a tray installed on a bottom of a water tank to form an area of a predetermined section and sampling aquaculture, and an image device is installed in the opening of the water tank so as to be spaced apart from the tray by a certain distance. When the tray samples the aquaculture, a rising frame installed on the bottom of the tray can acquire image data in the water by raising the image device to a height where the sampled aquaculture can be recognized, thereby preventing a damage of a fish body since it does not give excessive stress to the aquaculture. Since the sampling and image acquisition processes are automated within a specified time and a certain working time, the present invention can increase the efficiency of work time and labor and obtain a representative value for measuring the body size of the fish with higher reliability, thereby having an effect of easily measuring the biomass.

Description

Technical Field [0001] The present invention relates to a biofloat bioreactor,

More particularly, the present invention relates to a method and apparatus for bioprost biomolecule measurement, and more particularly, to a biofloor biomolecule measurement method and apparatus thereof, in which a process of collecting a sample in water and acquiring an image of a sample is automated so as to minimize stress of aquatic organisms, Discloses a bioprost biomass measurement method and apparatus capable of not only storing biomass measurement data but also reducing measurement work time and labor.

Biotechnology (BFT) technology is a method of cultivating heterotrophic bacteria and aquaculture species together. Heterotrophic bacteria decompose the organic byproducts in the water tank by 10 to 100 times faster than the decomposition by algae, and the organic byproducts decomposed by the heterotrophic bacteria are fed again to the aquaculture Therefore, it is not necessary to carry out a filtration process such as exchange of water for breeding water and water treatment in the biofloat culture process.

Heterotrophic bacteria used in aquaculture using biofract technology generally use microorganisms such as lactobacilus, photosynthetic bacteria and yeast, which are commonly used in fermented foods. In the aquaculture method, carbohydrate (starch, cellulose) is added to the water of the tank with an increased amount of nitrate to increase the amount of carbon, and when the carbon ratio is increased in the water tank, the microorganism produces the protein with the nitrogen as the nutrient, It is based on the principle of food.

Using biofloat technology, cultivating environmentally beneficial microorganisms for water quality can naturally purify the water and enable continuous use without replacing with new breeding water. It can also be used as food for natural proteins and amino acids produced by microorganisms. It is possible to block the inflow of diseases such as natural immunity (non-antibiotic) and viruses (innocent).

In addition, since organic matter of high nutrition is distributed in the breeding water, the growth rate is higher than that of cultured aquaculture in existing aquaculture, and the production efficiency is 20 to 50 times that of the existing productivity. In addition, Since it can breed, it has the advantage that it can produce aquaculture regardless of the season. Recently, it is expanding its target species with white prawns, eels, wild boar, loach and nidan koi. In this way, aquaculture using biofloat technology has various effects such as water purification, disease prevention, high production and feed efficiency, but it is necessary to create an environment suitable for biofloat culture.

In order to create an environment for bioflavonics, first, it takes time to settle microorganisms suitable for cultured species and environment. Secondly, it is necessary to control the titratable acidity of the breeding water because the oxygen supply is increased by accommodating both microorganisms and cultured fish. Finally, it is necessary to appropriately adjust the biomass according to the species of fish and the growth of the fish.

Therefore, for proper acidity control and biomass control, the farm should periodically estimate the biomass by measuring the size and weight of the fish body. However, since bioflocculation water is visually turbid due to heterotrophic bacteria and organic matter produced by aquatic organisms, it is difficult to measure aquatic organisms in the process of estimating biomass. Therefore, sampled aquatic organisms are taken out of the tank and measured .

However, such a measurement process can give stress to the aquaculture, and sampling is not an automated device, but it is difficult to obtain a representative value with a high confidence value because of a variation in human work, The smaller the size of the body, the more difficult it is to collect the sample, and the work time and labor are consumed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to specific configurations and accompanying drawings of a biofloat biomass measurement method and apparatus of the present invention.

Fig. 1 shows a farm where biofloor biomass measurement apparatus of the present invention is installed. As shown, the number of breeding habitats in a farm using BioFloc technology is dependent on heterotrophic bacteria and autotrophic bacteria (autotrophic bacteria) It is difficult to visually identify aquatic organisms that are mainly in the bottom of aquaculture tank.

Therefore, the aquatic organisms are periodically sampled and the body weight of the sample is measured outside the water tank and used as data. However, harvesting the aquaculture itself may cause excessive stress on the aquaculture organism and may damage the organism during the harvesting process. In addition, sampling is not directly performed by an automated device, but because it is directly performed by human operations. Therefore, it is difficult to obtain a reliable representative value due to a large variation. Therefore, biomass measurement at an accurate value is not performed. There is a problem that labor is consumed within a certain period of time.

2 is a schematic diagram of a bioprost biomass measurement method of the present invention. The biofloat biomass measurement apparatus of the present invention comprises: a sample capture step of collecting a sample of aquatic organisms distributed in a predetermined area partitioned in a culture water tank and raising a collected sample to a height of a water tank; An image data acquisition step of photographing and imaging the sample; A data processing step of analyzing and storing the acquired image data; And a breeding and management step of optimizing a biological environment based on the analyzed data.

The sample capture step involves capturing samples randomly within a specified time and within the specified compartment, and lifting the camera out of the water to an underwater height at which bioprolactic water can be recognized.

The image data acquisition step captures image data of the upper side of the aquaculture creature contained in the compartment specified in the sample capture step, and the aquaculture creature is photographed in water at the time of shooting. And includes a correction operation for minimizing the noise of the photographed image and performing conversion using a value set to be higher than the average value for all the pixel values so that the edge information as the contour line of the aquatic creature appears as bright as possible.

The data processing step includes receiving the corrected image, identifying and analyzing only aquatic organisms in the input image, storing the analyzed data, and controlling the biomass according to the inputted value.

The breeding and management step is controlled by the data processing step, and the breeding and management is applied according to the condition that the biomass input and the controlled amount of feed are fed and optimized for the habitat of the aquaculture.

3 is a perspective view of the biofloat aquatic biosensor of the present invention. A biofloat biomass measuring apparatus according to the present invention comprises a water tank (10) having a polygonal water tank bottom and a water tank external wall formed therein and having an open top; A sample collecting part 100 formed with an area of a predetermined section provided on the bottom of the water tank; And a video apparatus 200 installed at the opening of the aquarium to be spaced apart from the sampling unit.

Preferably, the sampling portion is formed in a square structure of 10 to 30 cm, and a jaw having a predetermined height is formed at the corner portion of the square. The height of the jaws is to prevent the sample collection part from being detached from the sample collection part when lifted. The bottom of the square of the sampler is made of a mesh of a certain size so as to minimize the resistance by the number of reared water when the harvesting part is lifted up to the water surface and to facilitate drainage. It is preferable that the size of the mesh can be exchanged by having a sample collection part having various kinds of mesh sizes depending on the size of the living creature, and the installation position of the sample collection part is formed at the corner part constituting the water channel of the culture water tank. In the lower part of the sample collecting part, a rising frame 102 for raising the water height to a certain level is formed, thereby raising the water up to a height of 3 to 10 cm below the water surface. The lifting frame can work not only in the form to be mounted in water, but also in a hoist action by connecting the rope from the upper part of the water tank to the sampling part. A sensor capable of measuring weight can be mounted on the ascending frame 102 or the pulley connected to the rope so that the weight of the creature placed on the sample collecting part can be measured and used as the data.

It is appropriate that the imaging device is installed on the outside of the water or on the ceiling. Since biofloat water contains a large amount of useful microorganisms and organics, it is opaque and turbid in appearance, so if the imaging device is installed in the water, It can be difficult to acquire. The video device may include a camera for capturing an image, a system controller having a user interface for performing data communication according to a predetermined communication protocol, and a memory for storing the input video, but is not limited thereto.

Fig. 4 shows Embodiment 1 of the biofloat aquatic biosensor of the present invention. Example 1 of the measuring apparatus according to the present invention shown in FIG. 4 is suitable for measuring macrobenthos or aquatic organisms with little fluidity, such as abalone and sea cucumber, attached to the bottom or sidewall. In the case of aquatic organisms having little fluidity, it is preferable that the sampling unit is formed at the same height as the bottom of the tank, and the tray 101 is divided into a certain area and placed at a certain distance from the bottom of the tank And a rising frame 102 for raising the camera installed in the water tank opening to an underwater height at which the aquatic organism can be recognized.

The tray may be formed in various ways depending on a device for recognizing an image. When analyzing a photographed image in color contrast, a tray may be formed as a white background, and a grid device may be formed on the upper side surface and a measuring device such as a veneer caliper may be formed on the edge of the tray.

The system for analyzing the photographed image based on the measurement devices automatically recognizes the measurement size so that the measurement value can be stored without carrying the separate measurement equipment separately. The rising frame is installed in the lower part of the tray and gradually rises so that the aquaculture is not stressed at a predetermined time inputted to the control part. The lift frame raises the aquaculture sampled in the tray to a height that can be identified by a camera installed outside the water, and then stops. It is possible to obtain a camera image that clearly indicates that the water is moved to a water depth of about 3 to 5 cm below the water surface.

Camera photographing is carried out with the target organism stagnant in the water. Since the process of acquiring the image without stress is sampled, the sampled organism is automated, It is easy to obtain a high-reliability representative value. The measured data is stored for a certain period of time, the representative value is designed through the accumulated data, and appropriate biomess amount and feed amount can be inputted into the system according to the representative value. Accordingly, in the case of aquatic biota through which the data is inputted through the above process, suitable breeding management can be controlled according to the inputted value immediately after obtaining the bio-image data, .

Fig. 5 shows a second embodiment of a bioprost biomass measuring apparatus according to the present invention. In the case of Example 1, there is a disadvantage in that it is difficult to carry out a sample capture step in a structure suitable for benthic organisms having little motion or a zoo animal having good activity such as a swimming animal. Therefore, in Embodiment 2 of FIG. 5, the isolation frame 103 can be installed for the purpose of catching a sample of a swimming creature.

5, an upper frame and a lower frame are provided on the upper side of the tray, and a net of mesh having a smaller diameter than the fish body of the aquatic creature is formed between the upper and lower frames. The magnets are installed on the edge of the upper frame, and the rising frame is gradually raised to a certain height by capturing the sample. When the living organism is recognized on the tray, the magnet member provided on the upper frame is exposed to the stationary member provided on the upper opening, As the isolation frame is lifted up and unfolded, it is fixed so that the creatures placed on the tray do not come off. When the rising frame is lowered again, the magnet member can not overcome the descending force, and the fish trapped in the lower frame separated from the stationary member is floated into the water tank to be detached.

By using biofloat aquaculture system, it is possible to automate the whole process of sampling and acquiring images in order to minimize the stress of aquatic organisms in the water, Therefore, it can be used industrially because it can contribute to increase income of fishermen by improving international competitiveness of aquaculture technology.
