A three-dimensional culture device for large yellow croaker and blue crab and its nested culture method

Abstract

The invention relates to a pseudosciaena crocea and green crab three-dimensional culture device and method. The pseudosciaena crocea and green crab three-dimensional culture device comprises a floating net and a crab pot. The floating net comprises a floating frame and meshes, wherein the floating frame is a closed polygonal framework, floaters are installed below the floating frame, the floaters are connected to the framework of the floating frame in a strip shape, the meshes are installed surrounding the floating frame in a circle, a container with a top opening is defined by the meshes, and the top opening is matched with the floating frame in shape. The crab pot is placed on the floaters, wherein the side wall of the crab pot is provided with a through hole, and a cover is arranged on the crab pot in a matching mode. The pseudosciaena crocea and green crab three-dimensional culture device and method have the advantages that cage culture of pseudosciaena crocea is realized, and aquatic water is fully utilized at the same time; cage culture of individual green crabs is carried out on an upper layer of a net cage, so that mutual killing of the green crabs is avoided, and the survival rate is up to 95%; besides, bait is fully utilized, the number of waste residues is small, the self-cleaning capacity of the aquatic water is enhanced, balance of the fishery ecological environment is realized, economic benefits are obtained, and the carbon sink function of fishery is also effectively achieved.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional cultivation of fish and crabs, and in particular relates to a three-dimensional cultivation device for large yellow croakers and blue crabs and a nesting cultivation method thereof. Background technique [0002] Global warming has seriously affected human production and life. In order to alleviate the warming trend and reduce greenhouse gas emissions, developing a low-carbon economy has become an inevitable choice for all countries. Three-dimensional marine ecosystem farming is a green and low-carbon farming model at the level of marine ecosystems. This model optimizes the population structure of the marine ecosystem, utilizes the interaction between different populations, improves the efficiency of carbon sinks, and ultimately achieves a win-win environment and economic benefits. [0003] Large yellow croaker is one of the traditional "four major marine products", the main economic fis...

Problems solved by technology

[0003] Large yellow croaker is one of the traditional "four major marine products", the main economic fish in my country's coastal waters; large yellow croaker is mainly cultured in coastal cages, although it makes up for the shortage caused by the shortage of wild large yellow croaker resources, but the water body has not been fully utilized , the fish species are easy to jump out of the box, and the light is too strong to affect the growth and feeding of large yellow croakers.
