Abstract

 In regarding to study the FECUNDITY and SPAWNING season of NEMIPTERUS JAPONICUS in KHUOZESTAN coastal, 482 specimens of this species were collected monthly by trawl net from Jun 2005 to May 2006 in KHUOZESTAN coastal. Biometric characteristic such as measurement of fork length, weight and body depth was done, in order to specify SPAWNING time, determining the sex maturity stage, ova diameter and gonadosomatic index (GSI). Ovaries were preserved and transferred to the lab taking the available standard methods into account before estimating the FECUNDITY. The maximum and minimum estimated FECUNDITY were 131321 and 10321 in samples with fork length 219 and 178 mm respectively. Maximum relative FECUNDITY was 713.54 and the minimum was 55.81 in fishes with 191 and 178 mm of fork length respectively. Considering the ova diameter in different stage maturity and variation of GSI in different months, indicates that NEMIPTERUS JAPONICUS starts SPAWNING between middle and end of spring. Results indicated that absolute FECUNDITY had the highest correlation related to gonad weight (r= 9.95) and relative FECUNDITY had the highest correlation related to gonadosomatic index (r= 9.94).
