NAGAPATTINAM: At a time when inland aquaculture is gaining a foothold in the district, which is otherwise largely dependent on sea fishing, ICAR-Krishi Vigyan Kendra in Sikkal is giving fresh impetus to the former by promoting genetically improved farmed tilapia (GIFT) with fish farmers. Experts say the variety of fish, when bred, can grow rapidly and bring benefits to farmers in a shorter period.

“Genetically improved farmed tilapia are those types of tilapia that are selectively bred and improved in their characteristics such as faster growth, disease resistance and tolerance to a wide range of food quality parameters. water,” said Dr. A Gopalakannan, ICAR-KVK program coordinator. .

Places where Cauvery or rainwater recharges neighborhood ponds are best suited for GIFT culture because it is a freshwater fish, he added. Since fish are raised for meat, experts say the GIFT chosen for breeding is all male. Only males should be reared and females should be kept as broodstock, they added, advising farmers to source only male hatcheries. They also recommend cultivating them in an enclosed agricultural environment such as a farm pond or a fish pond rather than in a natural environment such as a village pond.

“The farm environment is best suited for GIF tilapia as there are chances that they will mate with the tilapia if females are present. Cultivating the males in a farm pond will help them direct their energy – otherwise intended for mating – towards increased physical growth,” said E Hino Fernando, a fisheries extension expert who deals with advising on agricultural practices to increase fish production and income.

>From the time they are purchased from hatcheries and introduced to ponds, fish mature in about four months or so. They can be sold for meat from the fifth month. A Fisheries Department official pointed to state government programs such as the Multipurpose Farm Pond Scheme where farmers can get up to Rs 15,000 to set up farm ponds to rear these fish. In Pazhaniappan, a fish farmer from Naluvedapathy in Thalaignayiru block, said, “I can harvest GIF tilapia twice a year and get a profitable price when selling. I get double the profit by selling during the annual fishing ban.
