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
The bivalve shellfish seed that the present invention relates to aquaculture produces, and is specially a kind of marine products bivalve shellfish larval metamorphosis derivant and application thereof based on organic matter.
Background technology
The settlement and metamorphosis of seashells larva is a crucial link in its history of life; The generation of larval metamorphosis reaction, remove have with the hereditary feature of larva and developmental stage outside the Pass, also be subjected to the influence of envirment factor; By adopting certain chemical inducer, improve shellfish larval metamorphosis rate, the shellfish seed rearing is had crucial meaning.Domestic and international existing report mainly is the larval metamorphosis that adrenin and L-DOPA can promote bivalve shellfishs such as oyster, adopts GABA and metal ion can promote settlement and metamorphosis gastropodous such as red Bao.Bivalve shellfish is the important economic species of China's mariculture, annual being in great demand to seed, be used for the report that the shellfish seed produces, mainly be to utilize adrenaline and norepinephrine to be used for the production of cultchless oyster, such derivant relative price is higher, uses cost bigger in the large-scale production.
Summary of the invention
The object of the present invention is to provide a kind of based on being applicable in the large-scale production of organic matter used, cost is low raising marine products bivalve shellfish larval metamorphosis derivant and application thereof.
To achieve these goals, the technical scheme that the present invention takes is: marine products bivalve shellfish larval metamorphosis derivant, it is a kind of derivant based on amino acids, KCl:5.0～1000g/m composed as follows in water body
3L-tyrosine: 0.01～3.0g/m
3Cobastab
12: 0.01～0.5mg/m
3
The more excellent proportioning of described derivant in water body is: KCl:7.0～800g/m
3L-tyrosine: 0.02～2.0g/m
3Cobastab
12: 0.01～0.3mg/m
3
Above-mentioned derivant is used (handling abnormal prelarva) condition: 18～28 ℃ of water temperatures, salinity 25～35, pH value 7.0～8.5; Processing time is 0.5～48h; The preferred process time is 0.5～24h;
The culture density of larva was set according to the difference of shellfish kind during seed produced, and abnormal prelarva density is 5-20/ml water body.The shellfish larvae development of cultivating adds the derivant mother liquor for preparing to tangible eyespot occurring, reaches the concentration that needs.
Derivant keeps certain processing time after adding the pond of collecting seedling, and the larva bait throwing in is not fed in processing procedure.0.5-48h after, change fresh seawater in the pond, change normal incubation then over to.
The present invention has following advantage:
1. by extensive screening and rational proportion, obtained a kind of abnormal derivant prescription that marine products bivalve shellfish larva is had inducing action; It can improve the distortion ratio of marine products bivalve shellfish larva, and derivant is cheap.
2. the use of derivant of the present invention can improve larval metamorphosis rate 20-40%, improves the output of seedling of unit of water body effectively, enhances productivity.
3. suitable dose, processing time and the opportunity of inducing that this chemical inducer is used have been provided; Make it induce the efficient height, effect is stable, can improve the distortion ratio of bivalve shellfish larva effectively.
