The utility model provides a juvenile fish cultivation device and a three-dimensional juvenile fish cultivation system, and solves the problems that in an existing juvenile fish cultivation system, mechanical groove dividing operation influences juvenile fish growth, and a fixed cultivation groove is difficult to meet the juvenile fish growth requirement. According to the technical scheme, the device comprises a first breeding tank, a second breeding tank, a liquid level adjusting assembly and a sewage draining and filtering assembly; a water outlet and an overflow port are formed in the bottom of the second breeding tank, the first breeding tank is detachably mounted in the second breeding tank, and the bottom wall of the first breeding tank is of a permeable structure; the liquid level adjusting assembly comprises an overflow pipe, and the overflow pipe is arranged in an overflow opening in the bottom of the second breeding tank. The sewage draining and filtering assembly comprises a filter screen and a second connector, the second connector is connected with a water outlet in the bottom of the second breeding tank, and the filter screen is arranged in the second connector.

This utility model discloses a resource-based insect breeding rack, including a support frame and multiple breeding baskets stacked on the support frame. The support frame consists of a tray and four sets of legs evenly distributed at the four corners of the bottom surface of the tray. The top surface of the tray has right-angled supports at the four corners to accommodate and hold the breeding baskets. The bottom surface is provided with crisscrossing reinforcing ribs in a grid-like structure, integrally formed with the tray. A barcode scanning plate is located at the center of the grid-like reinforcing ribs, with a QR code label affixed to it. The advantages of this utility model are that it enables three-dimensional breeding of resource-based insects, not only increasing the insect carrying capacity but also significantly saving space, increasing breeding density, and ensuring breeding profitability. It facilitates quick and easy information retrieval via barcode scanning, allowing for precise tracking and management of the breeding baskets on the tray during the breeding process, achieving information-based management of resource-based insect breeding, and improving breeding efficiency and management accuracy.

This utility model relates to the field of aquaculture equipment and discloses a multi-layered, partitioned aquaculture net cage, including a support base. The bottom of the support base has a disassembly structure, which includes two compression grooves. Compression springs are fixedly connected inside the compression grooves. A limit block is fixedly connected to one side of each compression spring. A locking rod is fixedly connected inside the limit block. The bottom of the support base has a sliding groove, and a net is placed inside the sliding groove. Both ends of the net have locking slots that engage with the locking rod. In this utility model, the net is fixed using the locking rod and locking slots. Pulling the locking rod disengages it from the locking slots, and pulling the handle removes the net. The operation is simple and easy to maintain. The segmented disassembly eliminates the need for overall hoisting of the net cage, reducing work difficulty, improving maintenance efficiency, ensuring the integrity of the net, and increasing the availability of the equipment and the service life of the net.

This invention discloses a single-unit cascaded three-dimensional recirculating aquaculture system and method for giant freshwater prawns, comprising several vertically stacked three-dimensional aquaculture units and a recirculating water treatment unit. The three-dimensional aquaculture unit is constructed by directly stacking several boxes from bottom to top using an edge-supported method. Each box has a small feeding door on its front side wall. The boxes are divided into type A and type B. The top of the uppermost box is connected to an inlet pipe, and the bottom is a water collection unit connected to a return pipe and the recirculating water treatment unit to form a closed-loop circulation. This invention uses a support-free stacking method, significantly saving space and cost. The innovative diagonal cascaded staggered hydrodynamic design forces thorough mixing of water flow, eliminating short-circuiting problems. Individual isolation aquaculture completely solves the cannibalism problem among giant freshwater prawns, achieving a 100% survival rate and significantly improving the efficiency of factory-style aquaculture.

The embodiment of the application discloses a circulating water aquaculture system, comprising: an aquaculture pond, a solid-liquid separation device, an elevator, a protein separator, a biochemical water treatment device and a backflow unit, the aquaculture pond, the solid-liquid separation device, the elevator, the protein separator and the biochemical water treatment device are sequentially arranged along a water inlet direction, and the backflow unit is connected with the biochemical water treatment device and the aquaculture pond. The circulating water aquaculture system can make the treated aquaculture wastewater backflow to the aquaculture pond for recycling, so that the aquaculture pond only needs to supplement a small amount of water, which can greatly save water resources, greatly reduce the infection of pathogenic bacteria brought by additional water, and effectively improve the aquaculture density and the aquaculture quality.

This utility model relates to the field of bass farming technology, specifically a bass farming box with an automatic cleaning function, comprising: a tiered farming component and a cleaning component. The tiered farming component consists of a box body, limiting blocks, tiered plates, and a filter screen. The limiting blocks are installed on the inner wall of the box body. This bass farming box with automatic cleaning function, through the arrangement of the box body, limiting blocks, tiered plates, and filter screen, allows for tiered farming of bass by fixing the limiting blocks to the box body and connecting the tiered plates. The equidistant arrangement of the tiered plates facilitates the flow of water into all parts of the box, allowing bass of different sizes to be farmed in different water layers. For example, smaller fry can be farmed in the upper layer, while larger adult fish can be farmed in the middle or bottom layer. This fully utilizes the vertical space of the farming water body, increasing the farming density per unit water volume. Tiered farming improves space utilization and increases farming density.
