Cherax quadricarinatus circulating water breeding system and method

Abstract

The invention discloses a cherax quadricarinatus circulating water breeding system and method. The circulating water breeding system comprises a high-position water storage pond, a subsurface flow-vertical upward flow composite artificial wetland, a water quality restoration pond, a chlorella expanding culture bucket, a composite effective bacteria expanding culture bucket, a parallel breeding pond, a drainage channel, a water lifting inspection well and a water lifting pump which are all positioned in a heat-insulating greenhouse, the high-position water storage pond, the subsurface flow-vertical upward flow composite artificial wetland, the water quality restoration pond, the parallel breeding pond, the water drainage channel and the water lifting inspection well are sequentially communicated, the water lifting pump is used for lifting supernate in the water lifting inspection well to the high-position water storage pond, and the chlorella expanding culture bucket and the composite effective bacteria expanding culture bucket are communicated with the water quality restoration pond and controlled to be open and closed through valves. By the system, shrimp seed breeding rate is increased, shrimp seeds are synchronous in specification, supply of high-quality shrimp seeds is increased greatly, and development of cherax quadricarinatus breeding industry is promoted.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an Australian freshwater lobster circulating water breeding system and a seedling raising method. Background technique [0002] Australian freshwater lobster, also known as red claw crayfish, is an excellent freshwater shrimp farming species. With the continuous improvement of people's pursuit of quality of life, the demand for Australian freshwater lobster is increasing rapidly, and the scale of farming Australian freshwater lobster is also increasing. With the rapid development of my country's shrimp farming industry in recent years, the demand for shrimp seedlings has grown too fast, and the existing seedling breeding systems and methods have been unable to keep up with the growth of demand. [0003] The problems of low breeding rate of shrimp seedlings, unsynchronized seedling specifications and insufficient supply of high-quality seedlings in the prior art h...
