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.

[0032]The aquatic plant is at least one of purple-backed duckweed, hornwort, barracuda, water hyacinth and water peanut. Th...

Embodiment 1

[0035] Embodiment 1 provides a kind of culture method of Macrobrachium rosenbergii seedling, comprises the steps:

[0036] Step S1, seedling cultivation pool preparation: select a cement pool or an earthen pool that can control the temperature, ensure that the bottom of the pool is smooth and free of sludge, the pool wall is firm and watertight, and the irrigation and drainage facilities are convenient; then spray the whole pool with disinfectant for disinfection, and clean it with clean water Rinse well; add water to the culture tank, detect the amount of potassium ions and calcium ions in the water quality, adjust with potassium chloride and calcium chloride, so that the concentration of potassium ions and calcium ions in the water quality is 140mg / L, and then use Macrobrachium rosenbergii seedlings Test the water, if the Macrobrachium rosenbergii seedlings are not dead, then add some aquatic plants to the culture tank, and add water to a certain water depth;

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...
