Abstract

his study was conducted to investigate the biology of Common Pandora in Tellmatha coast. Species of (Pagellus erythrinus L., 1758) were caught in Tellmatha using longline during the period from April 2017 to August 2017. A total of 80 mature female specimens were examined for fecundity and gonadosomatic index study. The fecundity of the fish ranged from 1177.7 to 5818.18 eggs with an average value of 3512.09 eggs. The relationship between fecundity and gonad weight was most significant (r= 0.9775) than that of fecundity with other factors. The relations between fecundity and total length and body weight are linear. The regression equation are i) Log10F=4.6248+2.1379Log10TL, ii) Log10F=2.7203+1.4081Log10TW, iii) Log10 F= 0.5063+3.8624 Log10 Gw r = 0.8818. The spawning period started in June and continued until October. This data shows that the stock of the Common pandora of Tellmatha coast is being exploited in the limit. It would be desirable to take measures to protect the spawning stock and recruits, for example by introducing a closed season or various changes in fishing patterns.
