Systematics, fishery and biology of the white sardine Escualosa thoracata (Valenciennes, 1847) exploited off Kerala, south-west coast of India

Abstract

Landings of the white sardine Escualosa thoracata (Valenciennes, 1847) indicated a shift in their abundance from northeast to south-west coast of India and a sharp decline in the resource landings during the last decade along the entire range of its distribution. High local demand coupled with competitive price for the species might have led to overexploitation of this otherwise seasonal resources along the major areas of its abundance along the Indian coast. Detailed study on the systematics, fishery and biology of the species landed along Kerala coast was undertaken during 2015 and 2016. Stock assessment studies indicated near optimum fishing pressure on the resource along the Kerala coast.
