Abstract

Being the largest lake of the world and as a land–locked water body, The CASPIAN SEA accommodates one of the most precious fishery stocks of the world which are annually caught by BEACH SEINEs. These net are the single authorized means of harvesting bony fish stocks in coastal CASPIAN SEA waters along The Guilan, Mazandaran & Golestan provinces. The first use of BEACH SEINE dates back to 1900 - and which does not seem to have been designed on any particular technical or tactical considerations. Due to lack of technically sound design of the fishing nets and their low selective fishing capabilities for catching the target species there have, unfortunately been large amount of by – catch substandard fish to such an extent that the non–standard fish caught has accounted for nearly of total landings in recent year. The average length of KUTUM, the dominant fish species caught by fishing cooperatives using BEACH SEINE was 55 cm 80 years ago which has been plummeted down to 37 cm in 2007. Therefore it is noticed that during the past 80 decades a sum of 15,000 tons of various bony fishes have been caught as by–catch. These fishes include Rutilus frisii KUTUM, Liza auratus, Liza saliens, Cyprinus carpio, Rutilus rutilus caspicus, Vimba persa, Chalchalburnus chalcodes, Aspius taeniatus, Alosa sp, Barbus brachycephalus caspius, Abramis brama orieais, Sander lucioperca, Salmo trutta caspius, Silurus glanis, Esox lucius, & sturgeons. There have, so far, been no scientific bases or standards for the design & construction of fishing gears that could upgrade the utilization of commercially important fish stocks in the Iranian side of the CASPIAN SEA.
