Metamorphosis inducer and its applications based on organic matter for young insect of bivalve shell of seafood

Abstract

A metamorphosis inductor based on organic substances for the larvae of dual-shell shellfish is prepared from KCl (5.0-1000 g / m3, L-tyrosine (0.01-3 g / m3 and VB12 (0.01-0.5 mg / m3 through proportionally mixing. Its advantage is high metamorphosis percentage increased by 20-40%.

Description

technical field [0001] The invention relates to the production of aquaculture bivalve seedlings, in particular to an organic matter-based marine bivalve larvae metamorphosis inducer and application thereof. Background technique [0002] The 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; through the use of 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 that adrenaline 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. Bivalve molluscs are an important economic species of marine ...

AI Technical Summary

Problems solved by technology

Bivalve molluscs are an important economic species of marine culture in my country. There is a great demand for seedlings every year. It has been reported that they have been used in the production of shellfish seedlings, mainly using adrenaline and noradrenaline for the production of single oysters. Production, the relative price of this type of inducer is relatively high, and the cost of using it in large-scale production is relatively high
