High-yield breeding device for shellfishes

Abstract

The invention discloses a high-yield breeding device for shellfishes, and belongs to the technical field of shellfish breeding. The high-yield breeding device for the shellfishes comprises a main bodyplate, breeding holes are uniformly distributed in the main body plate at intervals, an arched attachment tank is installed on each breeding hole, one side wall of each attachment tank is provided with a positioning hole, each positioning hole is provided with an inflatable pipe in a run-through manner, and the inflatable pipe is provided with a small hole in each attachment tank. The device provided by the invention is reasonable in structure and convenient for management, and has low costs, convenient production, high breeding density of the shellfishes, and good breeding weight gain, in the case of large-scale deep-sea breeding or weather encountering heavy wind and heavy rain, breeding boxes that are stacked layer upon layer are not turned over, and the attachment tanks and the main body plate sink into water for a long time without rusting.

Description

technical field [0001] The invention relates to the technical field of shellfish cultivation, in particular to a high-yield shellfish cultivation device. Background technique [0002] my country is a big country for shellfish farming. With the diversification of shellfish farming species and farming methods, increasingly mature farming technology and continuous expansion of farming area, the output of shellfish farming in my country is getting higher and higher. The increase in farming area and farming output has brought There are many farming and management problems that need to be solved urgently. Shellfish are generally herbivorous, mainly feeding on algae and organic debris, and have a rich bait base. The inner bay of the estuary has high nutrient content and can grow a large amount of phytoplankton. River runoff and injected urban sewage often contain a large amount of organic matter, which becomes a rich food source for shellfish and is an ideal place for shellfish farm...

AI Technical Summary

Problems solved by technology

The invention has the advantages of convenient management, low cost, convenient production, high breeding density, and good breeding effect. However, in the case of large-scale deep-sea farming, the invention needs to clamp the clamp strips into the attachment grooves and stack them layer by layer. In this way, the firmness of the card may not be high and it will fall down. The same situation will occur in the weather with strong wind and heavy rain. The attachment groove and the main plate will be rusted when they sink underwater for a long time.
