Breakthrough in mass scale seed production of Indian pompano
The ICAR regional center Institute of Marine Fisheries Research Central has made a breakthrough for the company for the first time in the world of massive seed production of Pompano.
The Indian Pompano (Trachinotus mookalee) is a marine fish of the Carangidae family. There is little overwhelmed by nature. Contains omega 3 and 6. It is sold in the national market in ₹ 200 to ₹ 300 a kg.
The species is distributed in the western Indo-Pacific region and in 15 countries of the Asian continent. In India, it has been reported both on the west and east coasts.
It sporadic events in bays and lagoons, and adult fish prefer shallow coastal waters with rocky areas.
A senior scientist in charge of regional center Subhadeep Ghosh told The Hindu that fish is considered a good candidate for species aquaculture because of its rapid growth rate, ease of adaptation to culture, rapid acceptance of artificial food , The pleasant appearance, good quality of the meat and high consumer preference. In addition, it can be cultivated successfully in tanks, ponds and cages.
In order to diversify Indian mariculture agriculture and seed production species began in the regional center with the collection of broodstock in 2011.
The initial success of small-scale seed production was reached in early 2014. However, seeds could not be produced constantly due to the loss of broodstock kept in the cage by the effect of catastrophic Hudhud cyclone that affected the coast Of Visakhapatnam that year.
The collection of the broodstock was launched again in 2015 and the fish is stored in the recirculation system of terrestrial aquaculture (RAS) for development and maturation.
“With the manipulation of water quality and feeding protocols, the fish were induced to generate in the RAS production and seed-scale mass was carried out in early 2017,” said Dr. Ghosh.
Metamorphosis from larvae to fry began on day 17 after hatching and was completed on day 22. After 30 days of culture the survival rate was approximately 17.2% and the fry reached a mean size Of 2.9 cm in length and 1.27 g in weight.
A few thousand fry were transported to the ICJMM Gujarat Regional Center and raised in nurseries for cage storage.
A few thousand fry were transferred to Nagayalanka in the Krishna district of Andhra Pradesh and treated before being poured into the pond. The remaining fryers, even a few thousand, are high in day care at the ICIPM Visakhapatnam Regional Center.
He said the seeds are stored in floating cages outdoors to develop very soon.
It was the first successful case in producing mass-scale apple apple seed from India, all over the world.
Success has raised hopes for the cultivation of farmed fish with seeds produced in India and offers ample room for Indian fish farmers as part of species diversification.
