Problems solved by technology

[0002] In the process of shrimp farming, as the ecological environment continues to deteriorate, seawater pollution is becoming more and more serious. Natural disasters such as typhoons, rainstorms, and tides have resulted in poor seawater quality, imbalanced aquatic environments, and irregular changes in the pH value and composition of seawater. Severe production cuts
In addition, in the breeding process, with the increase of the breeding time, various amino acids and amino acid salts released by shrimps and crabs during the growth process are not good for the survival of shrimps, and it is difficult to improve the survival rate of shrimp fry, which affects the rapid development of mariculture industry.

Embodiment approach 1

[0011] Embodiment one: a kind of cultivation method that improves the survival rate of shrimp seedlings, get sodium carbonate 32g, sodium bicarbonate 61g, edetate disodium salt 7g, add up to 100g, put into 30 cubic meters of seawater shrimp ponds in spring. Results: The prawns were highly active, the survival rate was 85%, and the emergence period was 43 days.

Embodiment approach 2

[0012] Embodiment two: a kind of culturing method that improves shrimp fry survival rate, gets sodium carbonate 45g, sodium bicarbonate 98g, edetate disodium salt 7g, adds up to 150g, puts into 30 cubic meters of seawater shrimp ponds in autumn. Results: The prawns were highly active, the survival rate was 70%, and the emergence period was 43 days.

Embodiment approach 3

[0013] Embodiment three: a kind of breeding method that improves shrimp fry survival rate, gets sodium carbonate 45g, sodium bicarbonate 50g, edetate disodium salt 5g, adds up to 100g, puts into spring 30 cubic meters of seawater shrimp ponds. Results: The prawns were highly active, the survival rate was 84%, and the emergence period was 43 days.

Abstract

The present invention and a culture method for improving the survival rate of shrimp seedlings are composed of sodium carbonate, sodium bicarbonate and ethylenediaminetetraacetic acid disodium salt (EDTA-2Na); the culture method for improving the survival rate of shrimp seedlings is calculated by weight The percentages are: 30-60% of sodium carbonate, 60-80% of sodium bicarbonate and 0-15% of disodium edetate. The invention improves the survival rate of shrimp seedlings by at least 25%, and has obvious economic benefits.

Description

technical field [0001] The invention relates to a breeding method for improving the survival rate of shrimp seedlings. Background technique [0002] In the process of shrimp farming, as the ecological environment continues to deteriorate, seawater pollution is becoming more and more serious. Natural disasters such as typhoons, rainstorms, and tides have resulted in poor seawater quality, imbalanced aquatic environments, and irregular changes in the pH value and composition of seawater. Production cuts are severe. In addition, during the breeding process, with the increase of the breeding time, various amino acids and amino acid salts released by shrimps and crabs during the growth process are not good for the survival of shrimps, and it is difficult to improve the survival rate of shrimp fry, which affects the rapid development of mariculture. Contents of the invention [0003] In view of the above, the purpose of the present invention is to provide a breeding method that...
