abstract
Study on Length Weight relationship and Condition factor of grey mullet Mugil cephalus Linnaeus, 1758 was conducted by collecting data from commercial landings of Pulicat Lake, Tamil Nadu during 2016. In total 415 specimens including 174 females and 241 males were collected and measured standard length and bodyweight in mm and gm, respectively. Standard length for males ranged from 70 to 165 mm and females from 100 to 200 mm. Slope value ‘b’ was estimated as 2.7638 for male and 2.7624 for female and 2.7653 for combined sexes. Established W = 0.00038 L2.7638 and W = 0.00040 L^2.7624 for male and female respectively. The value ‘b’ was considerably close to 3 indicates that rotund, strongly streamlined body. Regression Coefficient for combined sexes was estimated as 0.9068. Average condition factor value for combined sexes was found as 1.0155 with a range from 0.5249 to 1.5854 revealed wellbeing of fish was in good condition.
