Abstract

The length-weight relationship in J. vogleri and P. macrophthalmus can be described by the equations log W=-5.08923+3.07931 log L and log W—4.63735+2.89703 log L respectively. The length at first maturity in J. vogleri is estimated as 190 mm and in P. macrophthalmus as 147 mm. These two species appear to spawn atleast twice in a year during protracted spawning periods: November-June in J. vogleri and October - June in P. macrophthalmus.
