A team of scientists from the Central Marine Fisheries Research Institute, Mangaluru, has facilitated successful cultivation of Indian Pompano (Trachinotus mookalee) for the first time in Karnataka in the Swarna estuary at Padhthonse village, Udupi district, and its harvest was done from June 2 to June 26.
The pilot project began last November under the Scheduled Caste Sub Plan Programme, wherein the beneficiaries got hands-on training in various aspects of cage culture.
Indian Pompano fingerlings, measuring 2-3 cm, were procured from the marine finfish hatchery of the Vishakhapatnam Regional Centre of ICAR-CMFRI.
About 4,000 fingerlings, each weighing 3-4 gm, were released into cages at a density of 40-50 fishes per cubic metre after acclimatising them to the local condition.
The fingerlings were fed pelleted floating feed twice a day, amounting to 5% of their body weight, said a release from CMFRI-Mangaluru.
After a five-month grow-out period, the Indian Pompano was harvested in batches between June 2 and 26. The average growth observed during this period was 400-450 gm, resulting in a total harvest of 1,300 kg with survival rate of 90%.
The beneficiaries sold the harvested fish locally, fetching prices ranging from ₹450 to ₹490 per kg generating ₹6.1 lakh revenue. With expenses at ₹3.75 lakh, the net profit earned was ₹2.35 lakh in six months.
Success of the pilot would not only provide alternative livelihood for SC families, but also help other local communities. The success has demonstrated the rapid growth rate of Indian Pompano to reach the preferred table-size in six months and the favourable market demand for the same.
Cage cultivation of fish in coastal Karnataka began in 2009-10 in coastal rivers with over 900 cages being installed in estuaries till now.
The Fisheries Department, the National Fisheries Development Corporation etc., extended financial support to over 500 families. Seabass, Red Snapper and Snubnose Pompano were among the species grown in cages.
The research programme was led by A.P. Dineshbabu and his team of scientists comprising Sujitha Thomas, Geetha Sasikumar, Rajesh K. M., and Divya Viswambharan.
