Description
Summary:The aim is evaluation of landing freshwater fish, economics, and someassessment on future situation. By using with fishery statistics, economicvalues of the captured based freshwater fishes were investigated coveringperiod 2008-2017. 21 commercial species were indicated such as; chub (Leuciscus cephalus), trout (Salmo spp.), bream (Abramis brama), Beysehir bleak (Alburnusakili), sand smelt (Atherina boyeri),tarek (Chalcalburnus tarichi), tench(Tinca tinca), catfish (Clarias gariepinus), bighand goby (Neogobius spp.), mullet (Mugil spp.), rudd (Scardinius erythrophthalmus), frog (Rana spp.), pike perch (Percafluviatilis), snail (Helix sp.),common carp (Cyprinus carpio),transcaucasian carp, wels (Silurus glanis),eel (Anguilla anguilla), pike (Esox lucius), crayfish (Astacus leptodactylus) gibel carp (Carrasius sp.). They are generallycaptured with gill nets, trammel nets, pots and cast nets. Total productionamount was 31768 tonnes in 2017 and tarek was the leading species with 9830tonnes and followed by gibel carp (7035 tonnes) and sand smelt (4892 tonnes). Totaleconomic value of captured freshwater species was 95.2 million TL representing4% of the Turkish fisheries economy. Results showed a gradual decline in thelast decade. The decrease in the yearly catch amounts are attributable to somereasons such as pollution, hydro-electric power plant construction,mis-management of freshwaters.
