Abstract

The invention relates to a method for cultivating young shellfish during artificial nursery, comprising withdrawing unicellular algae bait-rich pond water with water pump, filtering it with bolting silk mesh bag of 200-300 order to remove large-size zooplankton, inputting into nursery pool, and the young shellfish will take natural algae, bacteria and organic particle in pond water as bait to replace unicellular algae. The invention simplifies nursery course, reduces manual strength, and makes artificial nursery opera operational; the young shellfish grows fast and strong, the cultivating survival rate of shellfish in the sea is high. The natural algae in pond can be provided stably, which reduces risk of nursery failure with unicellular algae, the time for shellfish growing 2-4mm is reduced by 10-20 days, the shellfish can be cultivated in the sea in advance and the cultivation period is prolonged.

Description

A kind of method of in the artificial breeding process, cultivating juvenile mollusk
Technical field
The invention belongs to aquaculture method, particularly a kind of method of in the artificial breeding process, cultivating juvenile mollusk.
Background technology
China's Coastal Areas of South China is easy to suffer the influence of natural calamities such as typhoon, so carrying out shellfish cultures such as large nacre, nacre, pteria martensii, penguin pearl shell, scallop need be at the big specification seedling of nursery artificial culture, therefore, the floating larvae juvenile mollusk that needs to carry out certain hour after nursery pond adheres to is cultivated the breed of plunging into the commercial sea again.In traditional artificial breeding process, the bait of use is mainly the unicellular alga that chrysophyceae, flat algae, Chaetoceros etc. are cultivated through purifying.Swimming the stage of bivalve shellfish larva, the larva food ration is little, and the demand of bait such as chrysophyceae, flat algae is little, cultivates chrysophyceae, flat algae is comparatively easy.But the individual size increases of the juvenile mollusk after the metamorphosis is very fast, ingests, digestion power strengthens greatly, and therefore, the abundance of food that needs also increases greatly, needs to cultivate a large amount of unicellular algas, and this is a very hard work; And, carrying out being easy to take place the harmful animal pollution problems in the unicellular alga incubation in a large number, cause single-cell algae to cultivate failure, thereby directly cause the failure of growing seedlings or have influence on nursery effect.
Summary of the invention
The purpose of this invention is to provide a kind of method of in the artificial breeding process, cultivating juvenile mollusk, extract the abundant prawn culturing pond water of unit cell algae bait with water pump, after 200 orders~300 mesh sieve tulle bag filtrations are removed large-scale zooplankton, drop into nursery pond, juvenile mollusk is a bait with the natural algae in the water of extracted prawn culturing pond, bacterium, organic granular etc. then, replaces the unit cell algae of artificial culture; Throw something and feed every day 1~3 time, each feeding volume is 10~20% of a nursery pond water body, is standard with the little muddiness of water body in second day morning in the practical operation, if second day morning, water body was more clear, needs to strengthen daily ration, feeding quantity or increases the bait throwing in number of times.Well solve the stable supply problem of a large amount of bait of juvenile mollusk breeding phase, simplified the artificial breeding process, improved nursery effect.
Major technique solution of the present invention is: utilize in the prawn culturing pond water that obtains easily and can stably supply in a large number natural algae to carry out indoor raising of seedling pond juvenile mollusk and cultivate.Concrete technical measures are as follows: after the bivalve shellfish floating larvae adheres to, extract the abundant prawn culturing pond water of unit cell algae bait with water pump, after 200 orders~300 mesh sieve tulle bag filtrations are removed large-scale zooplankton, drop into nursery pond, juvenile mollusk is a bait with the natural algae (being mainly green algae and diatoms) in the water of extracted prawn culturing pond, bacterium, organic granular etc. then, replaces the unit cell algae of artificial culture; Throw something and feed every day 1~3 time, each feeding volume is 10~20% of a nursery pond water body, is standard with the little muddiness of water body in second day morning in the practical operation, if second day morning, water body was more clear, needs to strengthen daily ration, feeding quantity or increases the bait throwing in number of times.
The present invention has simplified the artificial breeding process, has alleviated labour intensity, makes artificial breeding technique have more operability; The juvenile mollusk fast growth of being cultivated, physique stalwartness, adaptability are strong, and spat goes out the pond and plunges into the commercial sea and culture the survival rate height; Prawn culturing pond natural algae generally can be stable a large amount of supplies, therefore, reduced because of the unit cell algae and cultivated the risk that failure causes the failure of growing seedlings; The time that will go out the big specification spat of the long 2~4mm of pond shell shortens 10~20 days, and the spat breed of can plunging into the commercial sea has in advance increased the breed phase.
Embodiment
Natural bait carries out the cultivation of bivalve shellfish juvenile mollusk in the prawn culturing pond water that utilization obtains easily, has well solved the stable supply problem of a large amount of bait of juvenile mollusk breeding phase, has simplified the artificial breeding process, has improved nursery effect.After the bivalve shellfish floating larvae adheres to, extract the abundant prawn culturing pond water of unit cell algae bait with water pump, after 200 orders~300 mesh sieve tulle bag filtrations are removed large-scale zooplankton, drop into nursery pond, juvenile mollusk is a bait with the natural algae (being mainly green algae and diatoms) in the water of extracted prawn culturing pond, bacterium, organic granular etc. then, replaces the unit cell algae of artificial culture; Throw something and feed every day 1~3 time, each feeding volume is 10~20% of a nursery pond water body, be standard with the little muddiness of water body in second day morning (what of bait in the water are muddy degree represent) in the practical operation,, need to strengthen daily ration, feeding quantity or increase bait throwing in number of times if second day morning, water body was more clear.Adopting the present invention to carry out the cultivation of bivalve shellfish juvenile mollusk compares with a large amount of unit cell algaes cultivation of traditional cultivation juvenile mollusk, simplified the artificial breeding process, alleviated labour intensity, made artificial breeding technique have more operability, applying of this technology will produce huge economic benefit and social benefit; Because food species is more in the water of prawn culturing pond, so the comprehensive nutrition that juvenile mollusk absorbed, the juvenile mollusk fast growth of being cultivated, physique stalwartness, adaptability are strong, and spat goes out the pond and plunges into the commercial sea and culture the survival rate height; Prawn culturing pond natural algae generally can be stable a large amount of supplies, therefore, reduced because of the unit cell algae and cultivated the risk that failure causes the failure of growing seedlings;
The time that will go out the big specification spat of the long 2~4mm of pond shell shortens 10~20 days, and the spat breed of can plunging into the commercial sea has in advance increased the breed phase.
