Abstract

Indian oil sardines ( Sardinella longiceps ) are undergoing morphological changes, which scientists believe, are adaptive techniques in specific habitats to maximise fitness and optimise habitat use. A group of researchers of the Central Marine Fisheries Research Institute (CMFRI), Kochi, arrived at this conclusion after assessing the morphological divergences of carrying out morphometric, genetic and nutritional analysis of the same species, which was available in three marine localities. The study aimed to understand whether the morphological differentiation was significant and whether they were genetically diverged. Researchers could visually differentiate two forms from commercial landings along the Kerala coast. The third variant was Indian oil sardines imported from Oman and which are available in fish markets, explained A. Gopalakrishnan, director, CMFRI.
