Abstract

Khouzestan coastal areas could be characterized from other parts of PERSIAN GULF by having shallow, high turbidity, fresh water discharge and several large creeks. Three main fishing sites in the area are Lifeh, Bahrekan and Mahshahr creeks. In these areas, METAPENAEUS AFFINIS was sampled and studied using research boat, dhows and bottom trawl. 25851 shrimps (47% males and 53% females) were studied in laboratory. Total length of females ranged 51-172 mm in Lifeh, 67-177 mm in Bahrekan and 38-163 in Mahshahr creeks. For males, these ranges were 64-148, 63-144 and 53-141 mm in Lifeh, Bahrekan and creeks respectively. Maximum mean length of males and females in the coastal areas was observed in March-July period. In coastal areas, GSI started to increase in March and maturity stages 3 and 4 were observed in March-July, indicating that the shrimp may spawn from mid-spring to mid-summer. Lesser amount of mean GSI and absence of stages 3 and 4 in the creeks showed that M. affinis shrimps do not spawn in creeks. Therefore, life cycle of M. affinis in KHOUZESTAN waters can be summarized as follows: Mature adults occur in seawater areas but smaller and immature juveniles occur mainly in creeks. Spawning migration occurs around March that during this month adult shrimps may gradually migrate from deeper waters to shallower coastal areas. The spawning takes place in coastal areas from July to August and the larvae spend their early stages in sea. After that, they are carried to creeks by tidal currents. Young shrimps stay in this area for feeding and growth until late autumn.
