Length Weight relationship of titan triggerfish Balistoides viridescens (Bloch and Schneider, 1801) (family: Balistidae) off Thoothukudi coast of Gulf of Mannar, Southeast coast of India (08° 53.6’N 78° 16’E and 08° 53.8’N 78° 32’E) – (36 m)

Abstract: Length-Weight relationship was studied in Balistoides viridescens, for a period of two years from January 2011 to December 2012. The slope value (b) estimated for Balistoides viridescens of both sexes was found to be 1.0541. The slope value (b) estimated for Balistoides viridescens male was found to be 1.4070 and for female 1.2257. The regression equations calculated for female was Log W = -0.4394 + 1.2257 Log L, and for male Log W = -0.7044 + 1.4070. The correlations coefficient was found to be significant (P<0.01). It was found in tropical waters from about 08° 53.6’N 78° 16’E and 08° 53.8’N 78° 32’E /36 M from Thoothukudi fishing harbour, southeast coast of India. The significant difference between sexes of the species ‘F’ value was at the 1% level. The b value differed from the ideal cube law of ‘3’ as is with the case of length-weight relationship studied in this species else-where. The slope value was compared here could be very useful for comparison with the balistids species in other geographical locations.
