چکیده
In this study, it is aimed to compare the yield and strength of crayfish fyke rigged with knotless net 210d/12 rope thickness those traditional material 210d/6 knotted which widely used in Turkey fishing (Pontastacus leptodactylus, Eschscholtz, 1823). The study was carried out on a monthly basis between June 2017 May 2018. total 300 nets, equipped 150 classical alternative were used. caught crayfishes measured weighted according they in. A 3509 caught, 1465 2044 net. Average CPUE value ranged from 10.93 (g/fyke net/day) 281.14 for per operation. gear found be 98.34 , while that determined as 79.46 net/day), no statistically significant difference average values (p>0.05). (± SE) 10.43 ± 0.27 kg, 210d / 12 identified 14.50 0.91 kg (p<0.05). Although has high strength, since lower by 19.20% compared gear, believed its use will not profitable.

Neural Net and Traditional Classifiers
Previous work on nets with continuous-valued inputs led to generative procedures to construct convex decision regions with two-layer perceptrons (one hidden layer) and arbitrary decision regions with three-layer perceptrons (two hidden layers). Here we demonstrate that two-layer perceptron classifiers trained with back propagation can form both convex and disjoint decision regions. Such classif...
