preparation example Construction

[0031] The disinfectant solution includes the following components by weight: 5-10 parts of euchlorine, 3-5 parts of potassium permanganate, 2-5 parts of sodium hypochlorite, 1-3 parts of chlorine dioxide, glycine-based chitosan quaternary ammonium 3-5 parts of salt, 200-300 parts of water. The preparation method of the glycine-based chitosan quaternary ammonium salt comprises the following steps: adding chloroacetylglycylglycine and water-soluble chitosan to an organic solvent, stirring and reacting at 60-80°C for 6-8 hours , followed by rotary evaporation to remove the solvent to obtain glycine-based chitosan quaternary ammonium salt. The mass ratio of the chloroacetylglycylglycine, water-soluble chitosan, and organic solvent is 1:(3-5):(15-20). The organic solvent is at least one selected from N,N-dimethylformamide, dimethylsulfoxide and pyridine.

Abstract

The invention relates to a method for culturing M. rosenbergii seedlings, which is characterized by comprising the following steps: step S1, preparation of a seedling cultivation tank, step S2, stocking of seedlings, step S3, feeding bait, step S4, daily management. Among them, the water depth of the seedling cultivation pond is 0.5-0.7m; the stocking density is 2000-4000 tails per square meter; the dissolved oxygen content is 5.5-5.8mg / L. The method for culturing M. rosenbergii larvae disclosed by the invention can significantly improve the adaptability of the larvae to fresh water and improve the survival rate of M. rosenbergii by simultaneously adjusting the salinity, temperature and bait during the culturing process of the larvae. The growth rate is accelerated, the food intake is fast, the stability is good, the nutrition is rich, and the immunity is enhanced, and the method is convenient and easy to implement and low in cost.

Description

technical field [0001] The invention belongs to the technical field of aquatic product seedling cultivation, and relates to a method for cultivating Macrobrachium rosenbergii, in particular to a method for cultivating Macrobrachium rosenbergii seedlings. Background technique [0002] In recent years, with the progress of society and the continuous improvement of people's living standards, the market demand for aquatic products is increasing, making the aquatic product breeding industry develop rapidly. The rapid development of the aquatic product breeding industry benefiting from modern farming technology has laid a solid foundation for ensuring the people's food basket needs. However, the stimulation of environment, disease and nutritional factors under the current breeding mode often causes a sharp decline in the transparency and smoothness of the water body, endangering the growth and development of aquatic products. [0003] Aquatic products refer to animals and their p...
