Rates of Target Species, Bycatches and Discards and Catch Composition-Fishing Gear Competition of Fish Capture Equipments used at Small Scale Fishery in İzmir Bay
Project no. 1177 · Status: Kapanmış · 2017
Summary
This research was conducted with the aim of determining the catch composition, catch rates and competition of species which were captured with fishing gears commonly used in small-scale fishery as trammel net, gill net, longline, wire pot, fyke net, cast net and hook lines. 439411 gr and 46 species were captured in total by trammel net operations. The mostly caught dominant species and its weight ratio was Diplodus annularis, %10.73. There were totally captured 72812.6 gr and 24 species in gill net operations. The mostly caught dominant species and its ratio was Boops boops, %36.51. 222144.9 gr and 32 species were caught in total by longline operations. The mostly caught dominant species and its ratio was Sparus aurata, %25.05. There were totally captured 136962.6 gr and 43 species in wire pot operations. The mostly caught dominant species and its ratio was Diplodus annularis, %3.14. 122285.3 gr and 29 species were captured in total by fyke net operations. The mostly caught dominant species and its ratio was Carcinus aestuarii, %15.12. There were totally captured 46002.6 gr and 23 species in cast net operations. The mostly caught dominant species and its ratio was Mugil cephalus, %11.28. 196649.8 gr and 24 species were captured in total by angling. The mostly caught dominant species and its ratio was Diplodus annularis, %5,01. According to the amount of catching species, the mostly captured species were obtained from trammel nets with the ratio of %27. Wire pots, fyke nets, hook lines, cast nets, longlines and gill nets followed this with the ratios as %23, %17, %12, %8, %7 and %6, respectively. This study will contribute to the development of catching target species in fisheries.
