Study on P.semisulcatus and M.affinis distribution in the Bahrkansar region
One of the most difficult problems in fisheries resource management is to adjust for the fishing season of a particular species to avoid overlapping with reproduction season of another. Penaeus semisulcatus reproduces in winter and is harvested in August, but Metepenaeus affinis demonstrates an opposite behavior in North-west of Persian Gulf. In such a condition catch season of one species may harm the resources of the other species, In order to preserve the resources of P. semisulcatus in fishing season of M.affinis, a survey on distribution of these two species was carried out by investigating the behavioral differences in the Bahrkansar region. The project was carried out in region between Gnaveh to Khoore- Mossa waters in North-west of Persian Gulf from Jan to March 2002, a total of 51 stations were sampled in a depth range of 10 - 30 meters using a bottom trawl net. Three shrimp species, namely P.semisulcatus, Parapenause stylifera and Carssicornis solenacera were caught. In all stations M.affinis was absent. According to cited references, the depths of less than 10 Ineters in the region is considered to be the habitat of M.qffinis. While occunence of P. semisulcatus was found to be rare. According to this study, unlike for M.affinis, the survey area is a suitable habitat for P. semisulcatus in winter. Therefore cosure of shrimp fishery in depths of 10-30 meters mey help protecting the resources of P. semisulcatuse.
