Three fisheries indicators in catch were: 1) percentage of mature fish, with 100% as target 2) percent of specimens with optimum length, with 100% as target and 3) percentage of mega-spawners, with 0% as target, and if no upper size limit exists, 30-40% as representative of reasonable stock structure. Over this period, the condition factor and relative weight had a decreasing trend. The range of length with optimum yield was between 40 and 48 cm. The mega-spawner measured as fish a size larger than 48 cm. According to these three indicators, the percentage of mature (fork length>40cm), optimum size and mega-spawners were 62.0, 40.9 and 12.5% in 1991-92 which decreased less than 50, 38.2 and 8%, in the years 1992-2011, respectively. The length structure is a matter of concern. Therefore, for reservation and rebuilt of kutum in the Caspian Sea, the target was to let all (100%) fish spawn at least once, using bigger mesh size in cod end (e.g. 35mm, during whole fishing season). The aim was also to implement a fishing strategy that result no (0%) mega-spawners being caught, and the main catch focus on optimum length. *Corresponding author}, Keywords = {Stock assessment, Fisheries indicators, Spawner fish, Caspian Sea, Iran}, volume = {21}, Number = {2}, pages = {53-64}, publisher = {IFSRI}, doi = {10.22092/ISFJ.2017.110055}, url = {http://isfj.ir/article-1-708-en.html}, eprint = {http://isfj.ir/article-1-708-en.pdf}, journal = {ISFJ}, issn = {1026-1354}, eissn = {2322-5998}, year = {2012} } @article{ author = {Fallahi, M. and Sharifian, M. and Toloii, M.H. and Amiri, A. and DaghighRoohi, J.}, title = {The effect of anaerobic fermentation of cow manure on culture of Rutilus frisii Kutum and comparison of survival and growth factors versus traditional feeding}, abstract ={Rutilus firisii kutum is one of the important fish in Caspian Sea that has significant economical role to the region.

This study was conducted in nine 1.7 hec pounds with 3 treatments with stocking densities of 1.7 million fish larva at Dr Yousefpoor Center at Siakal Village, 32km far from city of Rasht in North of Iran. The first treatment considered as control using concentrated food and grinded kilka fish. In the second treatment, the pound was supplied only by slurry for 13 days followed by concentrated fish food. The third treatment started with slurry for 13 days followed by slurry and concentrated food together. The physical and chemical parameters of water, plankton, biometry of fish, growth indices were monitored weekly. The result indicated that production was 1.7 to 2 times higher in slurry than traditional treatment also the survival rate was 1.7 times higher in slurry treatment. Slurry with several active substances is more effective and can promote the growth of zooplanktons that is the food for larval stage of Rutilus frisi kutum.
