Description

technical field

[0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating shellfish fry using aquaculture water. Background technique

[0002] In traditional aquaculture technology, seawater is generally directly introduced into seawater as aquaculture water for shrimp farming. Seawater may contain microorganisms harmful to shrimp, which are unfavorable to the growth of shrimp, and in the middle and late stages of farming, residual bait and shrimp feces are left behind due to a large amount of feeding. At the bottom of the pond, it is easy to cause eutrophication of the aquaculture water body, and the water body needs to be replaced in time. The discharge of the eutrophic water body will pollute the environment.

[0003] When cultivating shellfish seedlings, microalgae are needed as bait for shellfish seedlings. To cultivate microalgae, it is necessary to build a microalgae cultivation pond separately. To expand the cultiva...
