In the present study aim to examine the effects of the baited trammel nets alternative method instead of the long soaking times of trammel nets. A total of 405 individuals from 37 species were caught, including 143 from 9 target species, 93 from 18 non-target species and 169 from 10 other species. 98 non-damage individuals of target species comprised only 24.2% of total catch. The baited trammel nets were found as 1.56,1.6,1.2 times more efficient than non-baited nets for 3,5,7 days soaking times in the non-damage individuals of target species. The non-baited nets for only 1 day were determined as 1.5 times more efficient than baited nets. 109 damaged individuals (46.2%) were identified from the total target and non-target species in the baited and non-baited nets. As the soaking times increased, the number of damaged individuals in target and non-target, also other species increased. The addition bait affected individuals, whereas statistically insignificant. Consequently, the baited alternative method of trammel nets with 3 days soaking time can be recommended instead of the long soaking times considering negative effects on species for Turkish trammel net fisheries.
