Freshwater crayfish offspring high-density transportation technique

Abstract

The invention discloses a high-density transportation technology of young Procambarus Clarkii; the injury to the young Procambarus Clarkii can be reduced by improving the fishing technology and then the young Procambarus Clarkii is kept for 4 to 6 hours without feeding to reduce the excretion; the healthy young Procambarus Clarkii can be selected and reinforcement cages made from polythene are overlapped to enhance the transportation capacity; the humidity of the transportation environment can be maintained by adding aquatic weeds to increase the survival rate. The method utilizes the physiological property of Procambarus Clarkii and adopts non-water transportation to greatly reduce the weight and volume of transportation facilities, which is convenient for vehicle transportation. By adopting the method, the transportation time can be prolonged to 10 to 12 hours and the transportation survival rate can reach more than 90%; therefore, the aim of high-density transportation and low cost can be realized.

Description

Technical field [0001] The invention relates to a high-density transportation technology for aquatic economic animals, in particular to a high-density transportation technology for Procambarus clarkii seed and its application. Background technique [0002] Procambarus clarkii (Girard) is a freshwater shrimp, also known as red marsh crayfish, crayfish or crayfish. In animal taxonomy, it belongs to the class Crustacea, decapod order, crayfish family, and the genus Procambarus. The history of eating Procambarus clarkii in my country began in the 1960s, and it appeared in restaurants for sale in the middle and late 1980s. After the 1990s, due to consumers' awareness of Procambarus clarkii and extensive media promotion, domestic large The consumption of crayfish in middle cities is becoming more and more popular. Crayfish food has generally entered domestic restaurants, hotels, supermarkets and family dining tables. In Nanjing, Shanghai, Beijing, Hangzhou, Changzhou, Wuxi, Suzh...

AI Technical Summary

Problems solved by technology

[0003] The most traditional methods of transporting Procambarus clarkii seedlings are generally crude and cannot meet the conditions of high-density transportation. For example, the snakeskin bags that were often used in the past are resistant to damage because there is no frame support. The capacity is poor, and it cannot be stacked high enough to make full use of the compartment space, and due to severe extrusion, the transportation survival rate is low

The water tank transportation method is not convenient, the water consumption is large, the transportation efficiency is low, and the transportation cost is high
