Some observations on the biology of the ribbon fish Eupieurogrammus muticus (Gray)

Abstract

In the Kakin^da area Eupleurogrammus muticus is landed in small quantities in the commercial catches. Occurrence of a total of 245 post-larvae and juveniles of the length (S.L.) range 43-136. mm collected during March 1966 to April 1971 is reported. The phylogenetic significance in the loss of the caudal fin of the genus Eupleurogrammus, during ontogeny is discussed. Food and feeding habits, length-weight relationship, relative condition factor, size at sexual maturity, spawning and fecundity are studied.
