Artificial breeding method of pangasius sutchi

Abstract

The invention discloses an artificial breeding method of pangasius sutchi. The method specifically comprises the following steps: 1) transferring fishes from a river or selecting bigger juvenile fishes to yearly cultivate to obtain backup parent fishes, separately transferring female fishes and male fishes into a parent fish pond to breed before spawning; 2) selecting well-matured and healthy individual from the parent fishes; 3) artificially spawning, namely, injecting aphrodisiac twice to spawn; 4) inseminating by a dry manner, enabling sperm and egg to be mixed for 1 to 2 minutes so as to finish inseminating, spreading the oosperm to a fish nest, and then transferring the fish nest to a hatching pond to hatch; 5) cultivating with the water in a fish fry pond; 6) cultivating the fish fry, namely, testing water with a plurality of fish fries, and then transferring the fish fries into the pond to cultivate; 7) cultivating fingerling, namely, selecting strong, healthy and uniform individually with high water tracing performance to breed in a suitable place. According to the mode above, the artificial breeding method of pangasius sutchi has the advantages that the output of the pangasius sutchi is increased, the survival rate is greatly raised, and the breeding cost is decreased.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an artificial breeding method for freshwater sharks. Background technique [0002] The scientific name of the freshwater shark is Su's garden belly awn, which belongs to the family Miscanthaceae and the genus Miscanthus. Mainly distributed in Southeast Asia, native to Malaysia, Thailand and other places. Freshwater white sharks like to live at the bottom, and their ability to resist low temperature is weak, so they cannot survive the winter naturally. They are tropical and subtropical fish. [0003] Freshwater sharks have been introduced and cultivated by many countries and regions in Asia. The fish is favored by consumers in the market due to its tender and delicious meat, high nutritional value, and few intermuscular spines. Relying on imports has greatly increased the cost of breeding, and is subject to certain limitations. So far, the artificial breeding technology of this fish i...
