Abstract

The fishery and biology of Rastrelliger kanagurta, the Indian mackerel, have been studied from May 1965 to April 1968 at Cochin. The fishery comprises of juveniles during May-August and of commercial sizes during October-April, both at the commencement of the season being about one year old. For fixing the age of the fish and to explain its rate of growth before it appears along the coast, it is suggested that these two groups corres­ pond to two different broods. The growth determined by the length frequency studies has been found to agree fairly well with the return of some tagged fish.
