Abstract
Abstract Fishing nets are designed and manufactured for catching a target fish. Accordingly, the type and size of the netting yarns, strength length of the fishing nets are different. Keeping this strength is important for catching fish. Unfortunately, there is no specific standard for fishing gear in Iran. Therefore, a research was done to investigate strength of Caspian Sea beach seine. For this purpose, 20 samples were collected from net bag and wings of two fishing cooperative in the harvest season of 2014 and 2015. The samples was sent to Amirkabir University of Technology laboratory for study the strength length. The results show that the average of strength of both treatments (new net and used net) in both parts were the highest values. So that, the strength of new net in cod end was 318 kg/f, used net in cod end 295 kg/f, new net in wings 309 kg/f and used net in wings 301 kg/f. The results of one-way ANOVA test show that there was a significant difference among them (P <0.001). In addition, one-way analysis of variance show that there is a significant difference among the mean twist rates in the studied treatments (P <0.001). Studies showed that over time, the strength of this net has reduced, and this decrease was higher in the cod end.
