Abstract

Metapenaeus affinis (M. Edw.) is one of the three species of Metapenaeus represented in the fishery on the Malabar coast. This species enjoys a wide distribution in the Indo- Pacific region, occurring all along the Indian coast, Tokyo to Formosa, in waters of Hawaiian Islands (Kubo, 1949) and along Southern Africa (Barnard, 1950). The bionomics of M. dobsoni and M. monoceros are known in some detail through the publications oi Menon (1951 &'55), Menon and Raman (1961) and George (1959 & '61). The available information on M. affinis is limited to a reference to its occurrence along the Travancore coast by Chopra (1943), an account of its fluctuations in abundance in Bombay waters by Shaikmahmud and Tembe (i960), a brief discussion of its sex ratio in Cochin waters and some observations on its fishery and feiology on Cochin and Alleppey coast by George (1961), The following account of the biology of the species is based on the observations made at Calicut during the years 1957 to 1959.
