Problems solved by technology

Although these methods can thoroughly clean and disinfect the attachment base without leaving any organisms, they destroy the micro-ecological environment on the attachment base, and are not necessarily the most beneficial for the attachment of larvae.

Abstract

The invention relates to a treatment method of middle-late stage attaching bases in shellfish seedling breeding, in particular to a method for treating the attaching bases (mesh sheets, red palm ropesand the like) of shellfish (scallops, mussels, arca inflata reeves and the like) by using the benthic diatom film method, thereby greatly improving the larval attaching rate and the metamorphosis rate. The method has convenient operation and can treat a large number of attaching bases. The treatment method and the attaching bases after treatment have no pollution and are safe and environment-friendly; more importantly, the seedling attaching effect is significantly better than the attaching bases treated by using the traditional method.

Description

technical field [0001] The present invention relates to the optimization of seedling cultivation technology and technology of attached shellfish (scallops, mussels, cockles, etc.), specifically treating shellfish attachment bases with benthic diatom biofilms to improve the attachment rate of shellfish seedlings and Metamorphosis method. Background technique [0002] In the later stage of development of planktonic larvae of attached shellfish, the legs have developed and begin to look for suitable attachments to complete metamorphosis and become juvenile shellfish. During this process, the larvae have to complete a series of changes in shape and living habits, including the degeneration and disappearance of the face plate, from filtering feeding by the face plate to gills, and from swimming to secretion and relying on gill filaments to attach to life. At this stage, shellfish larvae are the most vulnerable; it is also where the greatest number of larvae are lost in actual se...
