Studying the condition of reserves Penaeid Prawn in Northwest coasts of the Persian Gulf

Penaeidae family is one of important index of shrimp stores in the Persian Gulf that has been studied the larva stores and fishing effort (SPUE) between 2012-14, also studied maximum of sustainable production (MSY) and the index of maximum of real withdrawal (MCY) on twelve years ago in the northwest casts of Persian Gulf. According to this the most abundant species that identified from penaeid larva are consist of Prapenaeopsis stylifera 1806 number and lowest number of Penaeus is P.semisulcatus (green tiger shrimp) consist of 181 number of total samples that be taken that average of larval density in 10 m² observed 250 number in surface unit in during the year, on the other hand by obtaining the average index of fishing effort in terms of kilograms per hour (Kg/h) 5.57 and the average of the maximum real withdrawal with KADIMA order in the last twelve years (1637.99 ton per year) and it’s comparison with capture average (1560.17 ton per year) in during mentioned period despite the harmony between averages of this two index, still decrease of liner trend of capture was observed with coefficient 0.87 because of lack of normal distribution during the last twelve years (P<0.01).
