1 Fisheries Research Institute, 32500 Eğirdir, Isparta – Turkey Viewed : 3834 - Downloaded : 3556 Fishing experiments were carried out with four trammel net types from May 1998 to August 1999, to determine the influence of net twine type (monofilament and multifilament) on efficiency of trammel nets for catching carp, Cyprinus carpio Linnaeus, 1758 in Lake Beyşehir and silver crucian carp, Carassius gibelio Bloch, 1782 in Lake Eğirdir. Each net type had four nets with mesh sizes of 56, 80, 100 and 120 mm (stretched mesh of inner walls).

Type A nets (monofilament inner wall and outer walls) were more efficient than the other net types (type B, monofilament inner and multifilament outer walls; type C, multifilament inner wall and monofilament outer walls; and type D, multifilament inner wall and outer walls) for capturing carp and silver crucian carp. Effect of monofilament net twine on efficiency of trammel nets was found to be 3.07 and 2.70 times higher than multifilament net twine for capturing carp and silver crucian carp, respectively. Monofilament inner walls of trammel nets were more efficient than multifilament inner walls for both carp and silver crucian carp. However, no significant difference in catching efficiency of monofilament and multifilament outer walls was found. Keywords : Monofilament, multifilament, net twine, trammel net, efficiency
