Abstract
The invention relates to a method for spawning, hatching and incubating scapharca subcrenata larvae in seawater disinfected by a bleaching solution. The method comprises the following steps of: under the condition that the water quality of the seawater for the seedling raising of scapharca subcrenata is blackened or a water surface has a large amount of foam, pumping the seawater to an indoor seedling raising pond, adding the bleaching solution, so that available chlorine in the pond is between 20 and 30 ppm, and precipitating for 48 to 72 hours; after precipitating, pumping the seawater to the other seedling raising pond, neutralizing residual chlorine by using sodium thiosulfate, and testing by using chlorine measuring test paper until the residual chlorine in the water is removed; introducing air into the seedling raising pond, putting unicellular algae in the addition quantity of between 0.02 and 0.03 million/milliliter; and after the water surface has white superfine air bubbles, putting breeding shellfish into the seedling raising pond in the addition quantity of 6 to 8 shellfish/m<3>, so that the breeding shellfish spawn and hatch, and breeding the hatched shellfish in the disinfected seawater after hatching. By the method, the problems that spawning and incubation of the scapharca subcrenata and the culture of the larvae are unstable are solved when the bacterium content of the seawater exceeds the standard; and the scapharca subcrenata can be grown to the length of 1,000 micrometers within 41 to 45 days, and the survival rate is between 30 and 35 percent.
Description
Technical field
The present invention relates to the method that a kind of blood clam is grown seedlings, particularly a kind of method of laying eggs hatching and cultivating the blood clam young with bleaching liquid sterilization seawater.
Background technology
Blood clam (Scapharca subcrenata) artificial breeding is through the development of more than ten years; Unstable aspect lay eggs hatching and larval culture; Have the producer of much growing seedlings to want to do and grow seedlings, but at the seawater of non-sterile, planting shellfish can not normal spawning; Though or can lay eggs, the young has more now the heavy phenomena of mortality.The main cause of above-mentioned phenomenon is a bacterial content severe overweight in the water, and it is current problem demanding prompt solution smoothly that blood clam is grown seedlings under the abominable situation of water quality.
Summary of the invention
The technical problem that the present invention will solve is that a kind of method of laying eggs hatching and cultivating the blood clam young with bleaching liquid sterilization seawater will be provided, and stablizes smoothly so that blood clam is grown seedlings, and can under the abominable situation of water quality, grow seedlings successfully.
Technical solution of the present invention is:
With the method that bleaching liquid sterilization seawater is laid eggs hatching and cultivated the blood clam young, its concrete steps are following:
1, when the seawater of the usefulness of growing seedlings as blood clam, the water quality blackout or the water surface have under the situation that significant foam produces, and are extracted into the indoor raising of seedling pond to seawater, add bleaching liquid, make that available chlorine reaches 20～30ppm in the pond, precipitate 48～72 hours;
2,,,, make in the water till the noresidue chlorine residue with surveying the test of chlorine test paper with in the sodium thiosulfate and chlorine residue with in the other nursery pond of post precipitation seawater suction;
3, in nursery pond, fill air, throw unicellular alga, nursery pond after white micro air bubble appears in the water surface, is put into planting shellfish in input amount 2～30,000/ml, makes its hatching of laying eggs, 6～8/m of kind shellfish input amount
3, hatching back seed selection is cultivated in the seawater of sterilization.
Advantage of the present invention is: with the bleaching liquid seawater of sterilizing, can make lay eggs hatching and cultivate stablely smoothly of blood clam, and under the water quality condition of severe, grow seedlings successfully.This technology is through the test of many times in 2008～2011 4 years, make blood clam from the hatching seed selection to going out pond to 1000 μ m with 41～45 days, survival rate 30～35%, blood clam is laid eggs hatching smoothly, the larval culture normal and stable of growing.
