Problems solved by technology

The former method often leads to the damage of a layer of biofilm formed by long-term accumulation at the bottom of the pond, and the dispersion of dirt at the bottom of the pond, which eventually leads to worse water quality in the seedling pond and seriously affects the emergence rate; the latter method is often caused by artificial operation. Transplanting results in damaged seedlings (early seedlings are very fragile), which eventually leads to low emergence

Abstract

The invention relates to a silvery pomfret larvae linking culturing device and a using method thereof. The device comprises a fry outward moving pond and a fry inward moving pond. The device is characterized in that the fry outward moving pond and the fry inward moving pond are connected through a connecting passage, a submersible pump is arranged at the bottom of the fry inward moving pond, an output end of the submersible pump is connected with one end of a water pump connecting pipeline, and the other end of the water pump connecting pipeline returns to the fry outward moving pond. The device has the advantages that pond changing operation can be conducted on silvery pomfret larvae with low damage, and the survival rate in a silvery pomfret larvae stage is effectively improved.

Description

technical field [0001] The invention relates to the technical field of silver pomfret juvenile cultivation, in particular to a silver pomfret juvenile bridging cultivation device and a method for using the same. Background technique [0002] Silver pomfret is one of the important marine economic fish in the east coast of my country. Since the beginning of this century, in view of the declining germplasm resources of silver pomfret in natural sea areas and its huge market demand, domestic researchers have gradually started the research and development of artificial breeding and breeding of silver pomfret. In recent years, with the continuous deepening of research, researchers from the East China Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences have taken the lead in successfully realizing the artificial breeding and breeding of silver pomfret. A number of innovative achievements have been made in developmental biology, breeding ecology, nutrition, a...
