Abstract
Description
technical field
[0001] The invention relates to the technical field of fishery cultivation, in particular to a device and method for graded cultivation of grouper fishery cement ponds. Background technique
[0002] Grouper has the characteristics of rich nutrition, delicious meat, low fat, and high protein. If the temperature is too high, the fish fry cannibalize each other. Therefore, after the seedlings have grown for a period of time, groupers of different sizes need to be separated to achieve graded farming. Traditionally, the cement pools used for graded grouper farming are usually equipped with repelling heads. The repelling head drives the fish school, so that the smaller seedlings can pass through the sieve to achieve graded breeding. However, due to the small size of the seedlings, it is easy to touch the fish body and cause damage to the fish body through the repelling head. Therefore, we propose The invention discloses a grouper fishery cement pond graded culture...
