Abstract

Detailed data collected on the fishery of Indian scad from Vellayil (Calicut) from 23rd August to 10th September, 1986, along with notes on some aspects of the biology of Decapterus russelli,the most important component of the fishery, are presented in this report. The gear employed was Pattenkolli, and the peak catch of scad was on 2nd September (178 tonnes). A random sample of 262 number of D. russelli was collected and studied the size distribution, maturity, length-weight relationships and price structure and utilisation.
