Catching Efficiency and Catch Composition of the Trammel Nets (Marya Nets) Used in Çanakkale Region
Abstract
In this study, It was aimed to determine the species composition, catch efficiency of
the trammel nets widely used in the Çanakkale coasts. The study was conducted commercial
95
fishing ground in the Çanakkale coasts between October - March. The study was carried out
by trammel nets with 36 mm, 42 mm and 46 mm inner panel mesh size and 160 mm outer
panel of mesh size. In the sea sampling, angleshark (Squatina squatina) 66.47 kg (16%),
cuttlefish (Sepia officinalis) 54.51 kg (13%) and common torpedo (Torpedo torpedo) 37.92 kg
(%7.64) was the most caught species by the nets respectively. In the study, catch per unit
effort (CPUE) for each nets has been determined as; catched target number and total weight
with dividing total nets length. In the trials, mean target fish catch efficiency for trammel nets
with different mesh size estimated as 1.54±0.7 kg/day (100 m). The study result show that
fishermen boats performed coastal fisheries have 20 – 40 (2000 – 4000 m) pieces deep
trammel nets on their deck is suitable.
