Can Tho University’s College of Agriculture and Fisheries in Can Tho City in the Mekong Delta region has announced its successful achievement in breeding cobia fish in controlled environment.
Research workers at the university college kept the parent fish in a cage under seawater off the Nam Du Isles in the Mekong delta province of Kien Giang. Once each fish reached 10-20 kilograms in weight, it was allowed to mate by use of proper hormones, which resulted in the fish multiplying naturally.
On an average, one fish laid from 300,000-900,000 eggs, all of which were then taken to a special aquarium for hatching. After three weeks, around 10-14 per cent of the young crop of fish is returned to its natural habitat to fend for itself.
This successful method in raising cobia fish will provide farmers with much more opportunities to expand their operations to a more lucrative market.
