Method for increasing crayfish fry transportation survival rate

Abstract

The invention discloses a method for increasing crayfish fry transportation survival rate, and belongs to the technical field of crayfish fry transportation; the method comprises the following steps:S101, cultivating crayfish fries in a paddy field in a micro-running water state, and improving the quality of the crayfish fries; S102, raising the temperature with shallow water in spring to promotehardening of shrimp shells of the crayfish fries; S103, setting a crayfish fry screening device, and screening out strong crayfish fries; S104, carrying out seamless connecting on the young fries from the rice field to a fry containing basket; S105, enabling the crayfish fries to be transported and washed, wherein after the crayfish fries enter the basket, the crayfish fries are washed with wellwater and field water in a mixed mode; and S106, spraying on the way: regularly mixing tap water, well water and field water to spray the crayfish fry during transportation. Through cultivation in a micro-running water state, crayfish fries are stimulated to intensively shell in advance, hardening of the crayfish fries is promoted, and the quality and the compression resistance of the crayfish fries are improved; and young crayfishes with strong physique are selected for moisturizing transportation so as to achieve the purpose of improving the survival rate of crayfishes in transportation, andthe crayfishes are promoted to be cultured in different places.

Description

technical field [0001] The invention relates to the technical field of crayfish seed transportation, in particular to a method for improving the survival rate of crayfish seed transportation. Background technique [0002] Procambarus clarkii belongs to Arthrophyta, Shrimp shell class, Crayfish family, Procambarus genus, also known as crayfish. It is loved by people and is the main species of shrimp farming at present. In recent years, due to the sharp increase in market demand, the natural resources of crayfish have decreased sharply, and the price has gradually increased. Therefore, artificial scientific breeding is used to meet market demand. Crayfish paddy farming has developed rapidly, and crayfish seed breeding in paddy fields has made some progress, but the seed has become the bottleneck of the crayfish farming industry. Due to the biological characteristics of crayfish seed, the survival rate of the seed is very low after long-distance transportation. , far from mee...

Problems solved by technology

Crayfish paddy farming has developed rapidly, and crayfish seed breeding in paddy fields has made some progress, but the seed has become the bottleneck of the crayfish farming industry. Due to the biological characteristics of crayfish seed, the survival rate of the seed is very low after long-distance transportation. , far from meeting the needs of production development; therefore, there is an urgent need for a method to improve the survival rate of crayfish seed transportation
