Method for acclimatization culture of shrimp postlarvae by using inland soda-type saline-alkali water

Abstract

The invention discloses a method for acclimatization culture of shrimp postlarvae by using inland soda-type saline-alkali water. By a water measuring acclimatization culture measure, large-scale shrimp postlarvae with higher adaptive capacity are cultured so as to solve the problem of stocking of commercial shrimp postlarvae cultured by the inland soda-type saline-alkali water. On the basis of water testing analysis, shrimp postlarvae culture pond water in primary shrimp places of coastal areas is taken as basic water, a method of adding the inland soda-type saline-alkali water into the basic water, feeding bait and propagating, and optimally regulating water quality is adopted, and an acclimatization culture speed that the alkalinity of the acclimatization culture pond water is improved by 1 mol / m<3> every 12 hours is adopted. By the method, NaCl shrimp postlarvae culture pond water with the alkalinity of 2.94mol / m<3> is changed into NaHCO3 inland soda-type saline-alkali water with the alkalinity of 37.29mol / m<3>, the survival rate of Litopenaeus vannamei Boone with the average specification of 0.8cm subjected to acclimatization culture for 18 days is 47.36 percent, and the average specification after the acclimatization culture is 2.73cm.

Description

technical field [0001] The invention belongs to the technical field of aquaculture in inland saline-alkali wetlands, and relates to a method for domesticating and cultivating sea shrimp seedlings in inland soda-type saline-alkali water. technical background [0002] In my country's "Three Norths" and coastal areas, there are abundant saline-alkali water resources. The fishery development and utilization of these saline-alkaline water resources is currently limited to breeding carp, crucian carp, and other freshwater fish with relatively strong saline-alkali tolerance in some lakes and swamp waters with a relatively low degree of salinization, and the water surface utilization rate is low. , the vast majority of water bodies are still in a barren state, and the benefits are low. Since the freshwater fish species that can be developed and cultivated are very limited at present, whether the seawater shrimps that have been widely cultivated in the coastal areas of our country c...

Problems solved by technology

The purpose of the present invention is to provide an effective method for domestication and cultivation. While promoting the formation of the environmental adaptability mechanism of sea shrimp seedlings, the individual size also increases to some extent, thereby obtaining large-scale high-quality sea shrimp seedlings with strong adaptability to solve internal problems.
