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] A few typical embodiments taking the marine bivalve shellfish hard clam as an example are given below, but the present invention is not limited to the following embodiments.

[0014] Before the inducer is used, it is prepared into a mother liquor of 1000 times the concentration with fresh water and stored at 4°C for later use. When in use, the inducer mother liquor is added to the nursery pond 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 larvae seed for aquaculture, in particular to an inducer for the metamorphic mixture of marine bivalve larvae and its application. Background technique [0002] The attachment metamorphosis of marine shellfish larvae is a very important link in their life history. The occurrence of larval allergies 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, Increasing the metamorphosis rate of shellfish larvae is of great significance to the cultivation of shellfish seedlings. It has been reported at home and abroad that adrenaline, 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 red abalone and other gastropods. Reports that have been used in the produ...
