A STUDY ON FUNCTIONAL TREND ANALYSIS OF STURGEON FISH REPRODUCTION, RESTOCKING AND FISHERIES MANAGEMENT DURING 2000-2006 GUILAN, MAZANDARAN AND GOLESTAN PROVINCES IN THE SOUTH OF CASPIAN SEA

The Caspian Sea is the biggest enclosed sea of the world. The natural resources of the Caspian Sea are of high economic value and the biodiversity of the Caspian Sea is 2.5 times poorer than the biodiversity of the black sea and 5 times poorer than in the Barents Sea. Fisheries are very important industries throughout the Caspian countries. Acipenser is genus of sturgeons. With about 18 species, many of which are threatened, it is the largest genus in the order Acipenseriformes.This. This study was carried out to assess functional analyses of sturgeon fish restocking in the south of Caspian Sea at 2000 to 2006.Data base collected of each sturgeon fish rearing, propagation and restocking centers in fisheries area in three coastal provinces south of Caspian Sea and were used to assess the state of the fisheries development in the Caspian Sea ecosystem and compared. The results were statistifically analyzed using SPSS. Vr.11. statistical analyses performed and were shown for total restocking sturgeon species of each fisheries area centers in (2006) related of with last years was reduced 25 percent. Maximum and minimum releasing rate belonged to Acipenser persicus and Acipenser stellatus, respectively. Therefore in order to keep fisheries sustainable in Caspian Sea, excess fishing should be avoided and continue acipenser propagation and successful restocking. Our complete survey and investigation as soon as in Iranian journal were published.
