Description

Technical Field

[0001] The present application belongs to the field of fish egg debonding, and specifically relates to an automatic debonding device for sturgeon hatching eggs. Background Art

[0002] Sturgeon hatching is a fully manual process, requiring manual debonding of the eggs. Sturgeon eggs are sticky, typically becoming sticky 5-6 minutes after fertilization and reaching peak viscosity 15-18 minutes later. The presence of mucus can reduce hatching efficiency, so debonding is essential before hatching. Traditional debonding involves adding a talcum powder suspension or fine yellow mud to the container containing the fertilized eggs and manually stirring them to remove the stickiness. This process takes approximately half an hour to an hour, is time-consuming and labor-intensive, and the effectiveness of debonding is significantly affected by human factors. Inadequate debonding can cause the fertilized eggs to clump together, hindering development. Excessive debonding can damage the egg wall and cause death, both of which reduce hatchability. While hatcheries are striving to improve production efficiency, traditional debonding methods not only increase labor costs but also fail to achieve uniform debonding results, impacting subsequent egg hatchability and juvenile survival rates. The utility model replaces the manual debonding of fish eggs with mechanical and physical effects, which not only saves labor and effort, but also can debond multiple batches of fish eggs at the same time. While reducing labor costs, it can also realize standardized operation of the debonding process, effectively improve production efficiency, and better meet the production needs of sturgeon hatching enterprises.
