This utility model discloses a circulating water purification device for the cultivation of *Cetacea purpurea*, relating to the field of *Cetacea purpurea* cultivation technology. It includes a cultivation box with a flow guide frame at the top and a water storage tank at the bottom. The water storage tank contains a filter assembly, and its inner wall is connected to a vertically arranged water pipe. The beneficial effects of this utility model are: the cultivation box, composed of a frame and a glass plate, allows observation of the *Cetacea purpurea* inside the box from the outside; the flow guide frame, with its spiral structure, utilizes gravity to guide the water flow naturally, reducing power consumption and extending the water flow path, thus improving purification and oxygenation efficiency; the filter assembly purifies the water in the cultivation box; and the ramp and partitions simulate the flow of a natural river through a circulating water system.

This utility model discloses a high-efficiency and energy-saving ecological breeding pond for *Cetacea purpurea*, relating to the field of breeding pond technology. It includes a frame, with a filter box installed at the top of the frame. The inner wall of the frame is respectively provided with a first inclined plate and a sieve frame. Two sets of water conveying components are provided on the front of the filter box, and a funnel is installed at the bottom of the filter box. A fixing frame is fixed to the inner wall of the frame. The beneficial effects of this utility model are: the filter box can store filter material; when the water conveying components deliver breeding water to the filter box, the water can be filtered through the filter material inside; the first inclined plate can simulate the flow of a natural river through a circulating water system; and the sieve frame can filter the breeding water through the openings in its inner wall, while simultaneously collecting residual feed, feces, and harmful substances in the water.

This utility model discloses a channel catfish hatching device, relating to the technical field of hatching equipment. The utility model includes a hatching chamber with an operating table. Multiple cavities are arranged on the operating table surface, and hatching components are selectively placed in these cavities. Each hatching component consists of a flowing water hatching tank and multiple hatching troughs. An overflow port is provided on the side wall of the flowing water hatching tank, and a fry discharge pipe is provided on the end wall of the flowing water hatching tank. This utility model sets up independent flowing water hatching tanks on the operating table, draining water through the drain pipe and releasing fish through the fry discharge troughs. Each flowing water hatching tank forms an independent hatching environment. The farmer only needs to periodically inspect the hatching chamber, shake the hatching troughs when necessary, and remove the plugs when releasing fish, simplifying the hatching process and operation. It also solves the problem that existing devices cannot be used to hatch different batches of channel catfish fertilized eggs.

The application discloses a method for thawing frozen channel catfish fillets by using magnetoelectric coupling, and comprises the following steps: placing the frozen channel catfish fillets into a sealed bag and placing the sealed bag into a magnetoelectric coupling freezing and refrigerating box; inserting a thermocouple temperature probe into the center of the meat sample to monitor the temperature in real time; and stopping the magnetoelectric coupling when the temperature reaches a predetermined temperature, thereby completing the thawing. The method can reduce the damage of the channel catfish during thawing, improve the quality stability of the thawed channel catfish, and has high thawing efficiency.

This invention relates to the field of aquaculture technology, specifically to a highly efficient and large-scale artificial breeding method for *Catfish bream*. The method includes a seedling cultivation step; the water in the seedling tank is obtained by treating fresh aquaculture water with fertilization, and the water in the seedling tank contains initial feed for *Catfish bream* fry; the initial feed includes rotifers and cladocerans. The fertilization method involves: after filling the seedling tank with fresh aquaculture water, sprinkling soybean milk, a dispersion of bacterial and algal nutrient paste, and a dispersion of algal polypeptides onto the water surface, and then adding rotifers to the water in the seedling tank. This technical solution can solve the technical problems of existing artificial breeding techniques for *Catfish bream*, which have many weaknesses and cannot meet the demands of modern aquaculture for efficient, stable, and high-quality seedling production. This technical solution has the advantages of improving breeding efficiency, ensuring seedling quality, adapting to large-scale production, reducing costs, and being environmentally friendly, making it suitable for efficient and large-scale artificial breeding of *Catfish bream*.

The application provides a spotted seal catfish SNP molecular marker combination, a probe, a 50K liquid phase chip, a kit and application, and belongs to the technical field of gene chips.The GWAS site probe, the window method site probe, the gender site probe and the GWAS site sequence which cannot be designed are integrated to construct a complete initial probe library, and optimization is carried out, so that a spotted seal catfish SNP molecular marker combination including 53407 core target points is obtained.The 50K liquid phase chip prepared based on the core target points has high reliability (the core site detection rate reaches 98.21%) in actual application.The 50K liquid phase chip not only includes 53,407 core sites which are high in polymorphism and rich in function annotation, but also can capture a large number of flanking sites, and the total assessable sites are more than 126,000, so that the information flux and cost performance of detection are significantly improved, and a powerful tool is provided for molecular design breeding.

The utility model discloses a kind of rotating cylinder turning devices for processing stink carp, including bottom plate and the outer bucket of bottom plate top surface fixed connection, the top surface of the outer bucket is equipped with bucket cover, bucket cover is equipped with cylinder turning subassembly, the cylinder turning subassembly includes first motor, one side of the first motor is fixedly connected with the top surface of bucket cover, the output end of the first motor extends to the bottom surface of bucket cover and is fixedly connected with first gear, the bottom surface of the first gear is fixedly connected with turning-over rod.The utility model can be placed or taken when stink carp needs to be placed or taken by rotating to promote bucket cover to move upwards or downwards to reach the effect that stink carp is conveniently placed or taken by staff, simultaneously, by cylinder turning subassembly, stink carp can be stirred to make stink carp turn over, and when turning over, excess brine produced when stink carp is pickled can be removed, to avoid the problem that stink carp is rotten because of being soaked in brine.

This invention proposes a reef for overwintering giant spiny loach, comprising: a first reef tube, a second reef tube, a connecting plate, and a heating tube. The first and second reef tubes are parallel to each other and connected at both ends and in the middle by the connecting plate. The heating tube is installed along the length of the first and second reef tubes on their inner walls, and the inlet and outlet of the two heating tubes are connected by a connecting tube. This invention, by installing heating tubes in the first and second reef tubes, can heat the water inside and around the reef to meet the requirement of a water temperature above 15℃ for giant spiny loach overwintering. The heating tubes are heated by hot water provided by an air source heat pump water heater, avoiding direct contact between electrical wires and the water, reducing the risk of electric shock. The air source heat pump water heater has high thermal efficiency, reducing energy consumption and eliminating concerns about electric shock, thus meeting the needs of giant spiny loach for safe overwintering.
