The utility model provides a crayfish breeding device facilitating temperature adjustment, and relates to the technical field of crayfish breeding. The crayfish breeding device facilitating temperature adjustment comprises a bottom plate, and a breeding pond is arranged above the bottom plate. According to the crayfish breeding device convenient to adjust the temperature, through cooperation of the breeding pond, a threaded plate, a stirring plate rod and a stirring plate, the heating plate is heated in the heating cavity, heat is transferred into the heating pond to heat water in the heating pond, meanwhile, the stirring plate reciprocates in the heating pond, and the temperature of the crayfish can be adjusted conveniently. The water in the heating tank is mixed with the water in the culture pond, so that the water temperature of each position in the culture pond is kept consistent, and the problems that when the temperature of the culture pond of the crayfish is adjusted in the existing culture of the crayfish, the water temperature in the culture pond is easy to locally rise, the temperature in the culture pond is not uniform, the crayfish is possibly damaged, and the breeding cost is low are solved. Therefore, the survival rate of the crayfish is influenced.

The invention discloses a hepialus armoricanus larva breeding method, and relates to the technical field of cordyceps sinensis breeding. By introducing a precise control algorithm and an automatic management system, the environment control precision is improved, the temperature and humidity are precisely adjusted through a PID control algorithm, the environment fluctuation can be greatly reduced, and it is ensured that hepialus armoricanus larvae grow under the optimal environment condition. The survival rate and the growth speed of the larvae can be improved; meanwhile, the feeding strategy is optimized, the food supply amount is dynamically adjusted according to the growth model and real-time monitoring data, it can be ensured that the hepialus armoricanus larvae obtain a proper amount of food in different growth stages, and through fine management, the growth quality of the larvae can be improved, and resource waste can be avoided.

The invention provides a fish culture spawning device capable of controlling temperature, flow velocity and substrate conditions and an operation method. The fish culture spawning device comprises a culture ship, and a culture box for fish culture is arranged in the culture ship; a temperature control system for adjusting the temperature is arranged outside the breeding box; a water flow speed control system for adjusting the water flow speed is mounted on the breeding box; a substrate replacement system for replacing a substrate is mounted on the breeding box in a matched manner. The device can accurately control the temperature and the flow speed of the water body, the natural water quality of the river is used as the aquaculture water body, and diversified substrate conditions can be configured according to different fish breeding habits.

The utility model discloses a salmon and trout roe hatching device, which relates to the technical field of roe hatching devices, and comprises a rack, a support frame is fixedly connected to the top of the rack, a raw water inlet pipe is fixedly connected to the side wall of the rack, one end of the raw water inlet pipe is connected with a raw water tank, and a cooling and heating machine is fixedly mounted on the inner bottom surface of the rack. Water is added into the oxygenation pump through the raw water inlet pipe, the oxygenation pump is matched with the oxygenation pipe to discharge oxygenated water into the biological treatment pond, and the water in the biological treatment pond flows to the drainage pipe through a pipeline between the isolating valve and the treatment pond drainage valve, is guided to the circulating water pump through the drainage pipe and is pumped into the cooling and heating machine through the circulating water pump. According to the salmon and trout roe hatching device, the cooling and heating machine is matched with the flow guide pipe and the water discharging pipe to be used for adding temperature-adjusted water into the hatching drawer bodies, by arranging the cooling and heating machine, the temperature of circulating water can be adjusted, the water temperature is made to be suitable for salmon and trout roe growth, and the problems that an existing salmon and trout roe hatching device is not easy to control the water temperature, and salmon and trout roe hatching is affected are solved.

The application belongs to the field of fishery, and particularly discloses a device and method for off-season breeding of parent fish of Eleutheronema tetradactylum. The device comprises a water storage container and a breeding container connected with the water storage container. The water storage container is connected with a large constant temperature cooler. The breeding container has a plurality of breeding units, each of which is installed with an LED lamp and connected with a small constant temperature cooler. In the device, the seasonal breeding conditions are simulated by adjusting the temperature and light changes. The cold temperature accumulation treatment, temperature rising treatment and temperature jump treatment are sequentially performed. The feed fish is nutritionally enhanced before breeding to supplement the nutrition of the parent fish. Through the device and method, the Eleutheronema tetradactylum can be successfully bred in the non-natural breeding season, and the breeding, breeding and sales in the same year are realized, which is suitable for large-scale promotion.

The utility model relates to fish hatching technology field, and disclose a kind of temperature control oxygenation device for fish hatching fry, including hatching box, still including first motor and adjusting component, the bottom of hatching box is fixedly connected with the connecting base of the device for fixed, the front of hatching box is provided with the temperature detector for detecting the temperature inside hatching box. The fixed support seat is driven to slide inside support limit seat by the transmission of first drive wire rope, to adjust the direction of temperature and oxygen supply, so that the water in the water tank that needs to adjust temperature can be uniformly adjusted, ensure the growth environment of fish hatching fry, so that the area inside water tank can be uniformly oxygenated, ensure the growth rate of fry, prevent from causing anoxia or bubble disease, prevent fry from being in the high temperature, high oxygen of fixed device vicinity for a long time, produce stress response, ensure the feeding and growth of fry, reduce management difficulty, improve the breeding benefit.
