Bait feeding device and method for polyculture of shrimps and crabs

Abstract

The invention discloses a bait feeding device and method for polyculture of shrimps and crabs. The bait feeding device comprises a base, supporting legs are symmetrically arranged on the two sides ofthe lower end of the base, idler wheels used for walking are arranged at the lower ends of the supporting legs, a movable base is rotationally arranged at the upper end of the base, a push rod is arranged on the left side of the movable base, and a handrail convenient to hold is arranged at the left end of the push rod; and a storage barrel used for containing two kinds of bait is arranged above the movable base, the left side of the storage barrel is fixedly connected with the surface of the movable base through a supporting clamp, at least one rotating shaft is horizontally arranged in the storage barrel, and a plurality of cutters used for cutting and stirring materials are symmetrically arranged on the upper side and the lower side of the rotating shaft. The bait feeding device is designed according to existing requirements, a mechanism capable of quickly mixing the two kinds of bait is provided, the spraying direction and distance can be adjusted according to the requirement for the bait throwing position after mixing, then bait throwing operation is conducted, the feeding difficulty is lowered, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of breeding equipment, in particular to a bait feeding device and method for mixed culture of shrimp and crab. Background technique [0002] Exopalaemon carinicauda (Exopalaemon carinicauda), also known as white shrimp, green shrimp, five-bearded shrimp, winter prawn, etc., belongs to Crustacea, Decapod, Swimming suborder, Longarm Shrimp family, and White Shrimp. It is distributed along the coast of mainland China and In the shallow sea and low-salt waters on the west coast of the Korean Peninsula, the Bohai Sea and the Yellow Sea have the largest output, second only to Chinese shrimp and Chinese hairy shrimp. They are important small economic shrimps with a wide range of temperature and salinity adaptability, wide feeding habits, and strong fecundity. , fast growth, high economic value and other advantages. Portunus trituberculatus (Portunus trituberculatus), commonly known as swimming crab and flying crab...

AI Technical Summary

Problems solved by technology

[0004] During the breeding process, shrimps and crabs need to be fed with bait. The existing feeding method is artificial throwing. This method is inefficient, close to the distance, and the feeding effect is not good.
