Method for fishing, temporary rearing and long-distance transportation of larva fishes of barbus capito

Abstract

The invention discloses a method for fishing, temporary rearing and long-distance transportation of larva fishes of barbus capito. The invention relates to an operation method for fishing, temporary rearing and long-distance transportation of larva fishes in the breeding process, and aims to solve the problems that a method for fishing, temporary rearing and long-distance transportation of larva fishes of barbus capito takes great time and labor and the larva fish survival rate is low. The method for fishing, temporary rearing and long-distance transportation comprises the following steps: I,preparing an indoor larva fish temporary rearing pond and an opened living fish transportation vehicle, respectively arranging net cages in the indoor larva fish temporary rearing pond and the openedliving fish transportation vehicle, and placing oxygenation nano discs at bottoms of the net cages; II, fishing up larva fishes, transporting the larva fishes by using the transportation vehicle, andtransferring the larva fishes with water into the indoor larva fish temporary rearing pond; III, putting the larva fishes into the indoor larva fish temporary rearing pond, adding flowing water to stimulate the larva fishes, and at the same time opening an oxygenation valve to introduce oxygen; and IV, sub-packaging the larva fishes by using oxygenation nylon bags, putting the oxygenation nylon bags into heat-preservation foam boxes, and performing long-distance transportation. By adopting the method, the net pulling build-up process before fishing and net pulling can be avoided, one-time direct net fishing is performed instead, and through a temperature control procedure, the survival rate of the larva fishes can be increased.

Description

technical field [0001] The invention relates to an operation method for fishing, temporary breeding and long-distance transportation in the process of cultivating fish fry. Background technique [0002] Barbus capito (Barbus capito) is a rare large-scale economic fish in Central and Western Asia. It has excellent characteristics such as high salt-alkali tolerance, wide appetite, delicious meat, and fast growth. In 2003, the Heilongjiang Fishery Research Institute of the Chinese Academy of Fishery Sciences introduced and successfully transplanted it from Uzbekistan, which solved the problem of artificial breeding and breeding technology. Now it has formed a large-scale breeding in the country, with a pond area of ​​about 60,000 to 80,000 mu and a total output of 4 10,000 tons / year or more. [0003] In recent years, with the continuous expansion of the large barb aquaculture industry in my country, the demand for fry is also increasing, but most fishery producers still use th...

Problems solved by technology

[0004] The present invention aims to solve the problems of time-consuming and labor-intensive operation methods for fishing, temporarily raising and long-distance transportation of giant barb larvae fry, being greatly affected by weather, difficult to control outdoors, and low survival rate of fry. That is labor-saving, time-saving, less affected by the weather, and easy to control the operation method of fishing, temporary breeding and long-distance transportation of giant barb larvae
