“…Fishermen's opinions and attitudes have been explored for species that include Dalmatian pelicans, Pelecanus crispus, and other wetland birds in Prespa, Kerkini, and Vistonis lakes in Greece (Pyrovetsi and Daoutopoulos, 1989), Mediterranean monk seals in Greece (Glain et al, 2001), gray seals, Halichoerus grypus, in Cornwall, UK (Glain et al, 2001), and in the Baltic sea (Varjopuro, 2011), whales, dolphins, and porpoises in the Mediterranean (Fratzis, 2007) and otters, Lutra lutra, in Czech Republic aquatic ecosystems (Vaclavicova et al, 2010). In these studies, fishermen are reported as having negative attitudes and opinions toward these species because they are perceived to be responsible for damages caused to fishing gear and/or as competitors to their fishery.…”
