Problems solved by technology

However, the current Japanese technology is deficient in sewage collection, sewage discharge and circulating water treatment. After the larvae feed, the bait residue still exists in the water body. Although a part of the water volume has been renewed through the drainage pipe, it is not thorough enough. Internal corruption will cause deterioration of water quality and lead to low survival rate of larvae; at the same time, if ee

Abstract

The invention provides a circulating aquaculture system for eel fertilized egg hatching and fry culture. The system comprises circulating water treatment facilities and at least one incubator, wherein the circulating water treatment facilities comprise a water storage pond, a main water inlet pipe, a main water outlet pipe and a filtering pond, a first water pump is arranged in the water storage pond, a second water pump is arranged in the filtering pond, the incubator comprises a machine body, a water inlet mechanism, a pollutant discharge mechanism, a water injection mechanism and a water drainage mechanism, the water inlet mechanism, the pollutant discharge mechanism, the water injection mechanism and the water drainage mechanism are arranged on the machine body, the water inlet mechanism and the water injection mechanism are communicated with the main water inlet pipe through pipelines, the water drainage mechanism is communicated with the main water outlet pipe through a pipeline, and the lower portion of the pollutant discharge mechanism is connected with a pollutant discharge groove. The invention further provides a use method of the circulating aquaculture system for eel fertilized egg hatching and fry culture. The circulating aquaculture system for eel fertilized egg hatching and fry culture and the use method of the system are easy and efficient, large-scale hatching can be achieved in small space, and hatching efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a hatching culture system and a use method thereof, in particular to a circulating aquaculture system for eel fertilized egg hatching and larvae cultivation and a use method thereof. Background technique [0002] Eel is an important economic fish in my country. Due to the particularity of the life history of eel, its artificial reproduction has become a worldwide problem, and the seed required for artificial breeding has always been supplied by natural fishing. However, in recent years, eel fry resources continue to be in short supply and the price remains high, making it difficult to meet the needs of the aquaculture industry. It is urgent to carry out full artificial breeding of eel. In 2010, Japan Fisheries Research Center (JFAR) announced the success of artificial breeding of Japanese eel. The center obtained a small amount of second-generation eels by ripening the artifi...
