摘要：Andromous sturgeons species have
been classified as endangered species in
global scale and entered into Reddata Book in
many countries. It is well known that there were
6 or 7 sturgeon species inhabiting around
Turkish Black Sea coast and entering rivers,
mainly Kızılırmak, Yeşilırmak, Sakarya and
Coruh for spawning. Stocks of these species
declined sharply during 1970s due to
overfishing, dam construction, habitat
destruction and water pollution. As a result
protection and mangement measurements have
been implemented since then. However,
situation of stocks and habitats has continued
to worsen. On the other hand there has been
no comprehensive study on the life cycle,
population structure and habitats of these
species. Therefore, situation of stocks and
factors threatening these species are not
documented. It is fact that protection and
sustainability of these anadromous species are
our major responsibility and moral issue. The
main aim of the project is to determine current
status of the stocks, habitats, genetic variation
and to develop conservation and management
strategies and plans
