CMFRI scientists breed golden trevally in captivity

Kochi: Researchers at the Central Marine Fisheries Research Institute (CMFRI) have successfully developed seed production technology for golden trevally (Gnathanodon speciosus), a high-value marine fish. Captive breeding of this species is a breakthrough in mariculture in the country.

This fish is a potential candidate species for sea cage farming with huge market demand for both consumption and ornamental purposes.

Scientists at CMFRI’s Visakhapatnam regional centre achieved successful bloodstock development, captive breeding and larval rearing of the fish after five years of research.

Golden trevally or golden king fish is an ideal candidate species for mariculture (marine aquaculture) due to its faster growth rates, good meat quality, and huge market demand for both consumption and ornamental purposes. Farm gate value of the fish is Rs 400-500 per kg.

In India, fish landing observations show that golden trevally are landed predominantly at reef area fishing grounds in Tamil Nadu, Puducherry, Kerala, Karnataka and Gujarat.

A team of scientists led by Ritesh Ranjan started the research efforts on seed production of this fish at Visakhapatnam regional centre in 2019. “This is a significant milestone in Indian mariculture,” said CMFRI director A Gopalakrishnan.
