Problems solved by technology

The reports that have been used in the production of shellfish seed mainly use GABA to increase the metamorphosis rate of abalone larvae, but GABA has no effect on the metamorphosis rate of economical marine bivalve larvae such as hard clams, meretrix meretrix, bay scallops, and scallops. Function; bivalve mollusk is an important economic species of marine culture in my country, and there is a large demand for seedlings every year. Epinephrine and norepinephrine are used for the production of single oysters. The relative price of this type of inducer is relatively high. Expensive to use in mass production

Embodiment Construction

[0013] Several typical examples of marine bivalve clams are given below, but the present invention is not limited to the following examples.

[0014] The inducer was prepared into a 1000-fold concentration mother solution with fresh water before use, and stored at 4°C for later use. When in use, add the inducer mother solution into the nursery pool to make a given concentration.

Abstract

An inductor for the metamorphosis of larvae of dual-shell shellfish is a mixture of KCl, 5-hydroxytryptamine (3.814-387.4 g / m3). Its advantge is high metamorphosis percentage.

Description

technical field [0001] The invention relates to the production of marine bivalve seedlings for aquaculture, in particular to a marine bivalve larva metamorphosis mixture inducer and application thereof. Background technique [0002] The attachment metamorphosis of marine shellfish larvae is a very important link in its life history. The occurrence of larval allergy is not only related to the genetic characteristics and developmental stages of the larvae, but also affected by environmental factors; by using certain chemical inducers, Improving the metamorphosis rate of shellfish larvae is of great significance to the cultivation of shellfish seedlings. There have been reports at home and abroad, mainly epinephrine, norepinephrine and L-DOPA can promote the larval metamorphosis of bivalve molluscs such as oysters, and the use of GABA and metal ions can promote the attachment metamorphosis of gastropods such as red abalone. The reports that have been used in the production of ...
