Embodiment Construction

[0014] A method for cultivating prawns, comprising the steps of:

[0015] a, build the cement breeding pond, the depth of the pond is 40-50cm, dibromonitrilopropionamide is mixed with water in a weight ratio of 1:100 to make a sterilizing solution, clean the breeding pond with the sterilizing solution, and use the sterilized breeding pond with After washing with clean water, expose to the sun for 3-5 days, and then stop draining water when the water surface height is 30-40cm from the bottom of the pool;

[0016] b. Evenly sprinkle the original ocean crystal salt in the water, so that the concentration of the salt water is 12%-15%;

[0017] c. Sprinkle plant ash 5-6kg / mu, slag 1-2kg / mu, amino acid 0.02-0.03kg / mu, guano 2-3kg / mu, calcium and magnesium fertilizer 0.01-0.015kg / mu in the culture pond, Keep for 30-35 days;

[0018] d, at the beginning of April, select high-quality water celery seedlings and throw them into the culture pond, and sprinkle 100-120kg water celery seed...

Abstract

The invention relates to a prawn culturing method. The prawn culturing method is simple and comprises the steps that after a culture pond is cleaned through disinfection liquid formed by mixing 2,2-dibromo-3-nitrilopionamide and water at the weight ratio of 1:100, plant ash, sesame dregs, amino acid, guano and Ca and Mg fertilizer are scattered into the culture pond and kept for 30-35 days for enriching water; water celeries are used in cooperation with prawn culturing; at the early stage, saline with the concentration ranging from 12% to 15% is adopted for prawn culturing; at the later stage, the salinity of water in the culture pond is gradually lowered by changing the water in the culture pond; zinc-rich prawn feed formed by compound protein-zinc, iodine, vc, garlic, dried beancurd sticks, fenugreek roots, oat, corn flour and poria cocos powder is used for feeding prawns; meanwhile, the probability that the prawns are infected by baculovirus penaei viruses, white spot syndrome viruses and Taura Syndrome Viruses can be reduced by reasonably controlling the culturing environment.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating prawns. Background technique [0002] Prawns, scientific name Oriental prawns, also known as Chinese prawns and tiger prawns. Arthropoda, Crustacea, Decapod, Shrimpidae, Penaeus. Prawns are large in size and are commonly known as prawns. During the growth process, prawns have to go through dozens of molts, and every time they molt, they will get a larger growth; molting is an important symbol of the growth of prawns, which is directly affected by the external environmental conditions. Shrimp is named after the fishermen used to calculate the sales of "one pair" products in history. It is distributed in shallow coastal waters with a sea water temperature above 20°C. Prawns are sea prawns, which are a unique specialty in my country. There is artificial breeding for export to earn foreign exchange. However, due to changes in water qual...
