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.
