Abstract

Among the many high-valued marine tropical finfish that could be farmed in India, the golden trevally or the banded horse mackerel or golden king fish, Gnathanodon speciosus (Forsskal, 1775) of the family Carangidae (Jacks and pompanos), subfamily Caranginae, is an ideal candidate species, due to its faster growth rates, good meat quality, and market demand for both consumption and ornamental purposes. Golden trevally is generally is a reef associated fish and lives in company of larger fishes like skates, sharks, groupers etc, especially the juveniles acts as pilots for sharks. It is widely distributed throughout the tropical and sub-tropical waters of the Indian and Pacific Oceans. These fishes are basically. bottom feeders but are globally known to be trophies by anglers and fish gaming enthusiasts. It is a silver grey fish with yellowish colouration on belly, with scattered black patches and all fins coloured yellow and a black tail. The juveniles are more golden in colour with the black bands giving them a very attractive look and hence a preference for aquarium keeping. The golden trevally landing observations showed decreasing trends in its landing estimates i.e. 1106 t in 2019 reduced to 375 t in 2023
