Abstract

The invention provides a method for industrial cultivation of Macrobrachium rosenbergii seedlings, including the selection and treatment of broodstock holding ponds, selection of broodstock, feeding pretreatment of broodstock, rearing of broodstock, requirements for nursery ponds, and requirements for nursery ponds. For water quality treatment, observation of broodstock mating, larvae cultivation, and daily management of nursery ponds, etc., during water quality treatment, Chinese herbal powder fungicides are used to treat water sources, which is green and environmentally friendly, and reduces the incidence of broodstock and seedlings. The shrimp seedlings cultivated by the method of the invention have small individual differences and good quality, greatly improve the survival rate of the shrimp seedlings, and improve the economic benefits of farmers.

Description

technical field [0001] The invention mainly relates to a method for genetic breeding of shrimps. , especially relates to a factory cultivation method of Macrobrachium rosenbergii larvae. Background technique: [0002] Macrobrachium rosenbergii is also known as white-footed shrimp, Malaysian prawn, money shrimp, Penaeus wanshii, etc. It is known as the king of freshwater shrimp. The origin is concentrated on the coast of Ecuador, and it is currently one of the three largest shrimp species in the world.
