Problems solved by technology

The newly hatched young snails have the feeding habit of feeding on benthic diatoms when they open their mouths to feed, and like to move around in an environment where the light is not too strong. When the bait is insufficient, the snails will be slaughtered, especially the young snails that have just hatched and have large individual differences.
But after cultivating for a period of time, even if the bait is not enough, it is rare to find the phenomenon of cannibalism

Embodiment 1

[0020] A method for cultivating young snails in artificial seedling cultivation of picornus snails, comprising the steps of:

[0021] (1) Cultivation of benthic diatoms: 3 days after the parent snails produced oocysts, the benthic diatoms for the young snails to feed on were started to be cultivated in an outdoor cement pool; the bottom area of ​​the cement pool for cultivating benthic diatoms was 18m 2 1. The depth of the pool is 1.2m, and a drainage pipe with a height of 0.8m is installed at the water outlet; the pool surface is framed, and the sunshade net is used for shading; , add sand-filtered seawater, and then apply an appropriate amount of nutrient salts to cultivate benthic diatoms, continuously aerate and increase oxygen for 24 hours; add a certain amount of nutrient salts in the later stage, and exchange water for 2 hours a day, and cultivate for about 20 days , the base will be covered with benthic diatoms;

Embodiment 3

[0032] A method for cultivating young snails in artificial seedling cultivation of picornus snails, comprising the steps of:

[0033] (1) Cultivation of benthic diatoms: 4 days after the parent snails produced oocysts, the benthic diatoms for the young snails to feed on were started to be cultivated in an outdoor cement pool; the bottom area of ​​the cement pool for cultivating benthic diatoms was 19m 2 1. The depth of the pool is 1.2m, and a drainage pipe with a height of 0.9m is installed at the water outlet; the pool surface is framed, and shade nets are used for shading; , add sand-filtered seawater, and then apply appropriate amount of nutrient salts to cultivate benthic diatoms, continuously aerate and increase oxygen for 24 hours; add a certain amount of nutrient salts in the later stage, and exchange water for 2.5 hours every day, and cultivate for about 20 days , the base will be covered with benthic diatoms;

Abstract

The invention relates to a cultivating method of young snails in hemifusus tuba artificial young snail growing, and belongs to the technical field of aquaculture. The cultivating method comprises thespecific steps of starting to cultivate benthic diatom for the initially hatched young snails to ingest food in an outdoor cement pool the third day to the fifth day after hemifusus tuba parent snailsgrow oocysts, wherein adherance of the benthic diatom is white PVC plastic corrugated tiles; washing and disinfecting a young snail growing pool the second day to the third day before the young snails are hatched out of the oocysts, uniformly laying the adherance fully grown with the benthic diatom at the bottom of the young snail growing pool and loading the oocysts to a plastic frame to be putto the young snail growing pool to be hatched; sifting the size through a sifting frame the ninth day to the tenth day after the young snails are hatched, and pool dividing cultivation is conducted. The cultivating method is easy and convenient to operate, the technology is easy to grasp, requirements for the young snails who just come out of film to be opened for bait can be met, the mutual slaughter of the young snails can also be effectively lowered, the survival rate of young snail cultivation in hemifusus tuba artificial young snail growing is increased by a large margin, and the growth of the young snails is promoted.

Description

technical field [0001] The invention relates to a method for cultivating young snails according to the physiological and ecological characteristics of certain specific young snails such as feeding habits and activity rules in the artificial breeding of marine economic shellfish, in particular to a medium and young snails artificially raised A method for cultivating snails belongs to the technical field of aquaculture. Background technique [0002] With the continuous improvement of shellfish artificial breeding and breeding technology, the proportion of seawater shellfish production in my country's seawater aquaculture production has increased year by year. In 2015, the total production of seawater aquaculture reached 18.756 million tons, of which the output of cultured shellfish was 13.584 million. tons, accounting for 72.4% of marine aquaculture. As an important part of aquaculture in my country, shellfish farming has become a pillar industry for the marine aquaculture ind...
