Length-weight relationship, condition factor and sex ratio of tade mullet (Liza tade Forsskal, 1775) from Mawlamyine, Mon state, Myanmar

Abstract

The species of Liza tade were collected from Mawlamyine, Mon State, Myanmar during June 2018 to May 2019. The analysis of fishes was based on 1264 specimens ranging in size from 10 to 30cm and in weight from 15 to 190g. The length-weight relationship of L. tade was determined for males, females and combined sexes as W=0.016L2.82, W=0.016L2.84 and W=0.016L2.83 respectively. The samples have been found to be negative allometric growth pattern (b˂3). The results indicated that the value of correlation coefficient (r) for males, females and combined sexes were as 0.972, 0.975 and 0.973, which were closer to 1 indicating that the length-weight relationship was highly correlated. The condition factor (K) was recorded as 1.088 for males, 1.140 for females and 1.114 for all individuals respectively.
