Some preliminary observations on the Rastrelliger faughni Matsui occurring in the Madras Coastal waters

Abstract

A preliminary account on the biological observations on the Rastrelliger faughni Matsui occurring along the Madras coast is given. Unlike the Indian mackerel Rastrelliger kanagurta this species seems to appear in loose concenrations. The species contributes, though in a very minor way, to the fisheries during February-March, when adults above 220 mm in total length are mainly caught. Juveniles measuring 35-159 mm form a notable portion of whatever mackerel contribution to the shore seine fishery in March and April.
