Blue crab simulation nest and blue crab parent artificial culture device

Abstract

The invention provides a blue crab simulation nest, which comprises a nest body, a nest cover, a support net, a sand layer and an inclined slope plate, wherein the nest body is in a round container shape; the bottom of the nest body is provided with a bottom discharge pipe; the support net is arranged above the bottom, and is used for carrying and supporting the sand layer; an accumulation and discharging space is formed under the support net; a water inlet pipe and a discharge suction pipe are arranged at the middle upper part of the nest body; the nest cover is a net sheet provided with a fixed frame and completely covers a position above the nest body; the slope plate is a rectangular plate; one end of the slope plate is near the nest body; the other end of the slope plate is arranged in the center position of the sand layer. The invention also provides a blue crab parent artificial culture device formed by a plurality of simulation nests through array layered three-dimensional arrangement. Through the simulation nest provided by the invention, the blue crab can realize one blue crab in one nest or one pair in one nest; the exuviation death rate is reduced. The matching breedingis not interfered by external environment; the breeding efficiency is improved. The simulation nest can be integrated and assembled into a production line; three-dimensional building is performed; agreat number of ponds can be saved. The unified management and the regulation and control on conditions such as temperature, water flow and salinity can be convenient; the specific parent culture andjuvenile crab scaled breeding can be realized.

Description

technical field [0001] The invention belongs to the technical field of blue crab breeding, and in particular relates to a method capable of industrial cultivation and management, so that artificially cultured blue crabs can be bred into sexually mature parent crabs, and the artificial breeding of blue crabs can be realized through mating and breeding of egg-bearing crabs. An artificial breeding device for the parent of blue crabs for cultivating and raising seedlings. Background technique [0002] Scylla serrata, also known as Scylla serrata, is a famous edible aquatic product in my country because of its large size and sweet meat. At present, the breeding seed of mud crab comes from artificial breeding, and the sea area catches megalopa and catches natural crab species. In recent years, with the pollution of the environment and overfishing, the natural resources of blue crabs are facing depletion, which has limited the development of blue crab breeding that relies on natur...

Problems solved by technology

In recent years, with the pollution of the environment and overfishing, the natural resources of blue crabs are facing depletion, which has limited the development of blue crab breeding that relies on natural resources. In addition, the artificial breeding technology has not yet made breakthroughs, and large-scale breeding cannot be carried out. , the breeding development of mud crabs has stagnated
