| Abstract | ||
| This survey has been accomplished in order to obtain scientific solutions bed to meet the Iranian Fisheries requirements in using standard fishing nets for ed to white shrimp (Metapenaeus affinis), and to help preservation of this aquatic !I's of resource, and also to help the responsibles in programming the fishing ssue, activities and compiling specific rules on this regard. For this purpose and with attention to behavioral position of shirmps, four trawlnets were procured and have been used during 1991. high The nets were used in Khuor Musa district (khouzestan province) which is the habitat of white shrimp. Using the mathematical methods and curves, the from L25%, L50% and L75% parameters were calculated for all the nets. Fishing ;, are pressure was determined to be exploitable in the mentioned longitudinal iging groups. 26.90 The CPUE was also calculated and important informations were obtained about suitable exploitation of this aquatic organism, by studying the position s no of white shrimp resources, the fishing rate of this shrimp, and also the fishing rate of small and non commercial shrimps. All informations indicate that the than trawlnet no. 3 is the most suitable one. Specifications are given in the report. | ||
