Length-weight relationship of Upeneus vittatus (Forsskal, 1775) from the Gulf of Mannar coast (Mandapam, Tamil Nadu), India

Abstract

Length and weight relationship (LWR) provides vital information in fisheries biology. Length-weight relationship of Upeneus vittatus (Forsskal, 1775) were assessed during the study period from April 2012 to March 2013 in fresh condition separately for male and female from the Gulf of Mannar region. The LWR were significant (P ˂ 0.05) for both male and female. Two different logarithmic equations were derived separately for males and females. Males: logW = -1.9262 + 3.0296 logL, Females: log W = -2.0287+3.1187 logL. The regression coefficient values of 3.02 and 3.11 were obtained for males and females, respectively.
