Net cage device for breeding young macrobrachium nipponensis by directly putting berried shrimps in original pond and breeding method thereof

Abstract

The invention discloses a net cage device for breeding young macrobrachium nipponensis by directly putting berried shrimps in an original pond and a breeding method thereof. The net cage device comprises supporting seats, fixing rods, a breeding tank, a fixing frame and a feeding platform, wherein the supporting seats are arranged on a shrimp pond bottom; the fixing rods are fixedly connected to the supporting seats; the breeding tank is fixedly arranged on the fixing rods, the breeding tank is of a space frame structure spliced by hard rod pieces, the side wall and bottom face of the breedingtank are both covered with mesh cloth, and the top of the breeding tank is provided with an opening; the fixing frame is arranged on the tops of the fixing rods and used for assisting in stabilizingthe fixing rods; the feeding platform is used for placing feed, and comprises a flat cylindrical hollow tray body, the bottom of the tray body is closed, the top of the tray body is provided with an opening, the side wall and bottom face of the feeding platform are both covered with mesh cloth, the feeding platform is suspended on the fixing frame through a suspension wire, and the feeding platform is entirely located in the breeding tank. The provided net cage device for breeding the young macrobrachium nipponensis by directly putting the berried shrimps in the original pond and the breedingmethod thereof achieve direct breeding and culture of young shrimps in the original pond, and do not need young shrimp catching and pond division processes, thereby increasing the survival rate of theyoung shrimps.

Description

technical field [0001] The invention relates to the technical field of freshwater shrimp breeding seedling breeding, in particular to a cage device and a breeding method for directly placing egg-bearing shrimp in the original pond to breed freshwater shrimp seedlings. Background technique [0002] The scientific name of freshwater shrimp is Japanese river prawn, commonly known as river prawn and lake prawn. Freshwater shrimp is tender in texture, delicious in taste and rich in nutrition. It is a famous and precious aquatic product loved by the masses, and it is also an important freshwater cultured shrimp in my country at present. With the rapid development of the freshwater shrimp farming industry, the supply of fine freshwater shrimp fry is in short supply. Farmers are also increasingly aware of the importance of high-quality seedlings for aquaculture production. Therefore, it is necessary to sample scientific and efficient nursery technology for seed breeding of fine fr...
