Length-weight relationship of three species of belonids and a Hemiramphid from the Gulf of Mannar

Length-weight relationship and relatie condition factor of Tylarurus crocodilus crocodilus, Stronglura leium, Ablennes hians and Hemiramphus marginatus have been studied. The regression lines of these species have been found to be significantly different from each other. All the four species exhibit isometric growth following cubic law. The relative condition factor for all the four species shows values around unity almost throughout the size range examined except for the young ones of Ablennes hians indicating a healthy and robust condition and good combatibility to these species with the habitat
