Description
Technical Field
[0001] The utility model relates to the technical field of fish egg collection, in particular to a lossless and continuous collection device for high-quality floating eggs. Background Art
[0002] Fish are generally dioecious and fertilized in vitro. According to the surface characteristics and specific gravity of the eggs, they are mainly divided into sinking eggs, floating eggs and sticky eggs. Among them, most of the main marine economic fish in my country have floating eggs. In order to achieve large-scale breeding of marine fish, traditional economic species such as large yellow croaker and yellow croaker all use artificial induced spawning technology to achieve centralized spawning and obtain batches of fertilized eggs. However, due to the influence of different fish species, some important economic fish species such as silver pomfret and black sea bream are natural batch spawning types and cannot spawn at the same time. The spawning period is 2-3 days. Not only is the amount of eggs collected per unit time small, but the traditional trawl collection is very likely to cause damage to the eggs of thin egg membrane species. Some species cannot continue to spawn due to the strong stimulation of the trawl operation to the spawning parents. To this end, it is necessary to propose a non-destructive and continuous collection device for high-quality floating eggs to solve the above problems. Utility Model Content
[0003] In order to make up for the above shortcomings, the utility model provides a lossless continuous collection device for high-quality floating eggs, aiming to improve the problem that fish eggs will be affected in the long-term continuous production process if they are collected manually, which will affect the output of fish eggs and the reproduction of fish. At the same time, manual collection will also cause damage to the fish eggs.
