Prawn culture apparatus

Abstract

The invention discloses prawn culture apparatus. The apparatus comprises a culture box and a net box, wherein the inner walls of two ends of the culture box are provided with installation grooves, theinner walls of two sides of each installation groove are rotationally connected with the same screw rod, the outer wall of the circumference of each screw rod is rotationally connected with a slidingblock through threads, fixing blocks are installed on the outer walls of two ends of the net box, and the bottom outer wall of each fixing block is provided with a sliding groove matching the corresponding sliding block. In the prawn culture apparatus, arc-shaped sounding copper plates are arranged, and tilapia can move inside the net box, so that a driven water flow or the tilapia itself can hitconnecting plates, mounting plates and the like, one sides, close to the arc-shaped sounding copper plates, of the mounting plates can be swung up and down, thereby iron balls on rubber rods are driven to hit the arc-shaped sounding copper plates to make a sound to drive away prawns close to the net box, diseased shrimps are slow in response and can enter the net box through tapered holes in thenet box, and are caught and eaten by the tilapia, the spread of shrimp diseases in healthy shrimp populations can be prevented, and the workload of manual cleaning of the diseased shrimps is reduced.

Description

technical field [0001] The invention relates to the technical field of prawn cultivation, in particular to a prawn cultivation device. Background technique [0002] Chinese prawns, also known as Oriental prawns, formerly known as Chinese prawns, belong to the phylum Arthropoda, Crustacea, Decapod, Penaeidae, and the genus Penaeus. In the past, it was often called prawns because they were sold in pairs. Chinese prawns, sea-caught prawns, and yellowish prawns are male prawns, and cyan prawns are female prawns. In the past, they were often sold in pairs, so they were called prawns, also known as oriental prawns. Sea-caught non-farmed Chinese prawns are generally 30 grams -50 Grams, the larger the size, the rarer it is; the braised prawns made with this prawn is the most classic and famous dish. The shell is thin and the meat is crispy and soft, with a lingering aftertaste. [0003] Removal of diseased shrimp from shrimp culture ponds is one way to prevent the spread of shri...

AI Technical Summary

Problems solved by technology

However, the current method of artificially removing diseased shrimp has limitations such as untimely detection and incomplete removal, and it is difficult to control the outbreak of infectious diseases of prawns

In addition, there are also some shrimp farming models in the industry that adopt the method of polyculture of fish and shrimp to prevent and control shrimp diseases, but put in the natural enemies of shrimp, so that although some diseased shrimp can be preyed on, many healthy shrimps will also be preyed on. Cause people's loss, be inconvenient to people's use, therefore urgently need a kind of prawn breeding device to solve the above problems
