The aim is evaluation of landing freshwater fish, economics, and some
assessment on future situation. By using with fishery statistics, economic
values of the captured based freshwater fishes were investigated covering
period 2008-2017. 21 commercial species were indicated such as; chub (Leuciscus cephalus), trout (Salmo spp.), bream (Abramis brama), Beysehir bleak (Alburnus
akili), 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 (Perca
fluviatilis), 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 generally
captured with gill nets, trammel nets, pots and cast nets. Total production
amount was 31768 tonnes in 2017 and tarek was the leading species with 9830
tonnes and followed by gibel carp (7035 tonnes) and sand smelt (4892 tonnes). Total
economic value of captured freshwater species was 95.2 million TL representing
4% of the Turkish fisheries economy. Results showed a gradual decline in the
last decade. The decrease in the yearly catch amounts are attributable to some
reasons such as pollution, hydro-electric power plant construction,
mis-management of freshwaters.
