Method and equipment for culturing seawater pearl shell

Abstract

The invention relates to a method and equipment for culturing seawater pearl shells. Cage-box series connection is combined with a rigid frame plane hanging culture. Firstly, posts are nailed into rows at the bottom of a culturing plant; after pearl shells are put into the box bodies of the cage boxes, a plurality of box bodies are connected together in series with a rope and then are tied to thefixed posts; and the box bodies of the cage boxes keep a certain distance from a seabed. Each cage box comprises a box body and a matrix plate and has the characteristics that each box body has a single-layer or multi-layer structure; the top is provided with an opening; each layer is provided with transverse supporting bars and vertical supporting rods; the circumambience of the transverse supporting bars and the vertical supporting rods are connected with the matrix plates; the pearl shells are put into the box bodies; and the bottoms of the box bodies are provided with gridless bases. The method and the equipment can enhance the survival rate of the pearl shells, have convenient operation and are favorable for the growth of pearl shells. The equipment has long service life.

Description

technical field [0001] The invention relates to a method and equipment for cultivating pearl oysters, which are suitable for cultivating seawater and freshwater or pearl oysters. Background technique [0002] my country is a big country rich in pearls, and the South Pearl produced is famous both at home and abroad. It is known as "the West Pearl is not as good as the East Pearl, and the East Pearl is not as good as the South Pearl". Nanzhu refers to the pearls produced in the Beibu Gulf, especially the pearls produced in Hepu, Guangxi. The pearls produced in Hepu are dignified in quality, bright and clean, round and colorful, and are the best among pearls. Since the reform and opening up, my country's pearl farming has developed rapidly. In particular, Hepu Nanzhu in Guangxi has developed into the world's largest pearl breeding base and a pillar industry of the local economy, making great contributions to the economic development of Beihai and surrounding areas.

AI Technical Summary

Problems solved by technology

However, the vast majority of farmers in my country are still using the traditional method of shallow seawater culture, with little technological progress, and the method has not been improved for many years. In terms of pearl oyster culture equipment, the existing pearl oyster culture generally uses net bags or net cages. relatively simple structure

The cages in cage culture are generally made of nylon materials, and the appearance is a cage with a common cuboid grid. The common cage has the following disadvantages: First, the cage is in contact with the bottom of the water, and the sediment is easy to deposit on the bottom of the cage Second, the feces of pearl oysters cannot be discharged from the cage, resulting in water pollution. Third, the ventilation is poor. Fourth, the ability to resist wind and waves is poor.

Therefore, at present, due to the poor structure of pearl oyster culture equipment, they cannot withstand wind and waves, the quality of pearls has not been greatly improved, lack of market competitiveness, and the added value of products is low. The breeding efficiency of the entire pearl oyster industry is not high.
