Abstract:

Efficiencies of different trammel net types on capture of tench, Tinca tinca L. were investigated in Lake Beyşehir in Turkey between April 1998 and August 1999. Nets with an inner wall of monofilament and outer walls of multifilament (type A) were more efficient than the other net types (type B, monofilament inner and outer walls; type C, multifilament inner wall and monofilament outer walls; and D, multifilament inner and outer walls). Type A nets were 2.08, 1.79 and 1.08 times more effective than the types D, C and B for catching tench. Monofilament inner walls of trammel nets were on average 1.85 times more effective than multifilament inner walls. No significant difference in catching efficiency of monofilament and multifilament outer walls was found (P>0.05). The average size of tench caught in monofilament trammel nets was higher than those caught in multifilament trammel nets, although not significantly different.
