| Özet |
| The Kızılırmak and Yeşilırmak regions were the most important spawning areas of anadromous sturgeons in the Black Sea coast of Turkey until the end of 1980s. Since then, four hydroelectric and irrigation dams were built on these rivers and they blocked spawning migrations and destroyed spawning habitat of sturgeons. However, overfishing of sturgeon for caviar production at the river mouth caused a dramatic decline of stocks in the second half of the 20th century. Nowadays, sturgeon are extremely rare in the South Eastern Black Sea and they are listed under CITES as an endangered species. This study gives information about the current status of sturgeon populations (A. stellatus, A. gueldenstaedti, Huso huso) around the Black Sea coast of Turkey between 2004 and 2008 based on accidentally captures in different fishing nets and from illegal marketing in the early 21st century. It is recommended a management strategy is implemented for the Yeşilırmak Basin to protect and recover the sturgeon populations. |
