Nesli Tükenme Tehlikesindeki Mersin Balıklarını (Acipenseridae) Koruma Stratejilerinin Değerlendirilmesi

Abstract

Sturgeons have been living in natural waters of Europe, Asia and the Northern America for 200 million years. While they were abundant in lakes and rivers up to mid-twentieth century in the Northern Hemisphere nowaday their stocks are highly endangered. The decline of stocks are resulted from environmental degradation such as construction of dams on the rivers and restricting water flows, overfishing and water pollution, which become unfavorable to migration and reproduction of sturgeons. Several protective measures have been instituted in many countries; such as fishing regulations, habitat rehabilitation, stock enhancement and listing of all sturgeons under CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora). In this paper, the conservation strategies for sturgeons in the world and Turkey discussed and the efficiency of the protective measures evaluated.

Mersin balıkları Avrupa, Asya ve Kuzey Amerika’da 200 milyon yıldır yaşamlarını sürdüren balıklardır. Kuzey yarımküredeki nehir ve göllerde yirminci yüzyılın ortalarına kadar bol miktarda yayılış gösterirken günümüzde nesilleri yok olma tehlikesindedir. Stoklardaki azalmanın nedenleri, nehirlerde üreme göçünü ve üremeyi olumsuz etkileyen barajlar ve su rejimindeki sınırlamalar, aşırı avcılık ve su kirliliğidir. Birçok ülkede av yasakları, habitat rehabilitasyonu, stok takviyesi ve bütün türlerin CITES (Nesli Tehlikede Olan Yabani Hayvan ve Bitki Türlerinin Uluslararası Ticaretine İlişkin Sözleşme) kapsamında yer alması gibi çeşitli koruma tedbirleri alınmaktadır. Bu çalışmada, dünyada ve Türkiye’deki mersin balıklarını koruma stratejileri irdelenmekte ve alınan önlemler değerlendirilmektedir.
