Shellfish engineering culture method and shellfish multilayer flowing water culture device

Abstract

A shellfish engineering culture method is characterized in that the shellfish engineering culture method comprises the following steps of: (1) arranging culture carriers of multilayer structures in a culture space; (2) Layering and tiling shellfishes in the culture carriers of the multilayer structures; and (3) drawing seawater to feed into the culture space as culture water of the shellfishes, wherein the culture water flows out of the culture space after passing through the culture carriers of the multilayer structures from bottom to top, and the shellfishes on the culture carriers of the multilayer structures obtain natural bait in the rising culture water as food layer by layer. Living bait in a natural sea area is fully utilized, the seawater is drawn into the semi-enclosed culture space by a water pump, the culture space is designed in a rising flowing water mode, the culture water flows out of the culture space after passing through the culture carriers of the multilayer structures from bottom to top, and the shellfishes on the culture carriers of the multilayer structures obtain the natural bait in the rising culture water as food layer by layer. According to the shellfish engineering culture method, utilization rate of the natural bait is largely improved, engineering high-density culture of the shellfishes such as pearl shells is achieved, and culture benefit is increased.

Description

technical field [0001] The invention relates to a shellfish culture method, and also relates to a shellfish multi-layer flowing water culture equipment. Background technique [0002] As an important part of aquaculture in my country, the shellfish farming industry plays an important role in the domestic economy. The farming method and environment of shellfish farming play a vital role in the growth of shellfish. [0003] At present, shellfish farming is mainly based on bay farming and offshore farming. However, with the change of the offshore ecological breeding environment and the pollution of sea areas, the survival rate of shellfish offshore culture is very low. In addition, with the development and utilization of the bay and the development of industry, shellfish breeding places have been greatly reduced. In addition, the current shellfish farming model is outdated and the farming technology is backward, which directly leads to low shellfish farming density, slow grow...

Problems solved by technology

In addition, due to the limited pressure on the sling and the limited space in the cage, the traditional cages have a low density of shellfish culture and cannot achieve high-density culture
