Abstract: 

Total predation of 19 fish beach sein cooprative companies was evaluated in Golestan Province (Miankale, Khaje-Nafas and Gomishan Zones) by using of question forms and arrangement of special forms with them managements. Results were showed that predation ration of Rotilus frisii kutum was significantly more than two zones (Khaje-Nafas and Gomishan), as the ration of it strongly decreased from Miankale zone to Gomishan Zone. Inversely, predation ration of Cyprinus carpio was significantly more than two other zones and it strongly increased from Miankale Zone to Gomishan Zone. The ration of Mugilidae (Liza auratus and L.salince) was more less two zones. This different can be related to floor and it,s organisms. Regression model F test was significant. Also, T test parameters determined significant effect of Zones on the ration of the predation. Predation ration average in Khaje- Nafas and Gomishan Zones were 91466.9 and 50922.7 kg lower than Miankale Zone.
