Every year, after fishing period, the sturgeon gillnets are assessed base on physical characters
by the management of sturgeon fishes in Golestan Province. Net are put aside and replaced by
new one if they qualification are not net. In spite of importance of strength ropes,
unfortunately, there is a little research in this regards. In addition, previous research are not
applied storage conditions and physical damages. Therefore, researcher are determined to do a
research in this regards. For this reason some materials from new net, storage net, damaged
net, put aside net, etc. collected and tested by an Instron. Then data analyzed by factorial test
in complete randomized and variance and average compared in 5% significant level by SPSS
version 17. The results shows that there is not significant difference between new net (blank)
and new net kept in storage for two years in strength point (p〉0.05). However, there is
significant difference in breaking point, damaged nets (p〈0.05). Regarding the effect of
reducing, the net strength during the storage, lack of significant difference between new
storage net, represents a quality loss in making of new nets.
