Summary

The study compared the catch efficiency and impacts on chondrichthyan bycatch between monofilament and multifilament trammel nets in small-scale fisheries along the coast of Çanakkale, Türkiye. Multifilament trammel nets caught 1.22 times more target species (species with economic value) than monofilament trammel nets. Monofilament nets also had a higher catch rate of non-target (discard) species, including higher catch of species listed on the IUCN Red List as vulnerable, endangered, or data-deficient.
