Sealed inflatable upwelling culture device for intermediate culture of bivalve mollusks and culture method thereof

Abstract

The invention provides a sealed inflatable upwelling culture device for intermediate culture of bivalve mollusks. The device includes a culture pipe, a negative pressure pipe, filter nets, an inflatorand a water outlet pipe, wherein the culture pipe is the outermost layer of the whole device, a bottom end of the culture pipe is provided with the filter mesh, an upper end side wall of the culturepipe is provided with a water outlet hole, the negative pressure pipe is placed in the culture pipe, a bottom end of the negative pressure pipe is provided with the filter net, one end of the water outlet pipe is connected with the negative pressure pipe, the other end of the water outlet pipe is placed at the water outlet hole of the culture pipe, and the inflator is placed on the filter net inside the negative pressure pipe. The culture device is advantaged in that through the culture method, water and electricity resources are greatly saved, the growth rate of juvenile mollusks is 20% to 50% higher than the traditional method, the survival rate is over 90%, and the seawater and the bait can be saved more than 70%.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a closed inflatable upwelling cultivation device and a cultivation method thereof for intermediate cultivation of bivalve seedlings. Background technique [0002] my country has a huge marine shellfish farming industry. Shellfish farming is an important part of the marine aquaculture industry, and its output accounts for 80% of my country's total marine aquaculture output. Common bivalve molluscs such as clams, oysters and scallops are delicious, nutritious and have important economic value. With the continuous development of artificial breeding technology, more attention has been paid to high-efficiency factory breeding methods, and shellfish breeding has become an important part of the mariculture industry. [0003] In the process of factory breeding of bivalve molluscs, the intermediate cultivation of juvenile shellfish is a key technology. Studies have shown that the survival rat...
