Description

Salmonidae Fish Controllable Temperature Incubation and Breeding Device

technical field

The utility model relates to a fish hatching and breeding device.

Background technique

The cultivation of larvae and juveniles of salmonids such as rainbow trout is an important part of the fry cultivation process. In recent years, due to the continuous expansion of the breeding area and breeding density of salmonids in my country, the water quality, dissolved oxygen, ammonia nitrogen and other breeding environmental factors have keeps getting worse. At the same time, other environmental factors such as temperature and water pollutants are also under the condition of uncontrollable fluctuations. Under the combined effect of the above-mentioned multiple factors, the seedling hatchability and survival rate of rainbow trout are often all low (survival rate is generally about 60%). In order to improve its survival rate, the control and management of the breeding environment should be strengthened during the hatching and floating larvae and the cultivation stage of the newly hatched juveniles. Among them, the floating larvae refer to individuals that after the fry hatch, the yolk sac absorbs 2/3 and start to feed on the surface of the water. At this time, the total length of the fish is 18-28 mm, and the body weight is 70-250 mg. Newly hatched juveniles are individuals that have surfaced and opened their mouths to feed. It is of great practical significance to improve the hatching rate and survival rate of rainbow trout seedlings by systematically controlling the environment of salmonids such as rainbow trout from fertilized eggs to newly hatched juveniles.
