T. M. Yohannan, K.K. Balasubramanian and V. K. Janakai

The growth parameters of Indian mackerel and oil sardine were estimated from the data collected during the period from April 1996 to March 1998 from fish landing centres in and around Calicut. The Linf, K and amplitude (C) of mackerel were estimated as 265 mm, 2.4 and 0.7 respectively. The corresponding parameters for oil sardine were 200 mm, 2.1 and 0.6. Both the species showed a drastic reduction of growth rate during December to March, the period of low plankton abundance in the coastal waters. The fishable life span of both the species was estimated as around 16 months.
