Abstract :In this study were demonstrated length-weight relationships insert ignore into journalissuearticles values(LWRs); and some biological characteristic of four venomous fishes from Black Sea coasts. The most important venomous fish in the Black Sea coasts are common stingray insert ignore into journalissuearticles values(Dasyatis pastinaca);, greater weever insert ignore into journalissuearticles values(Trachinus draco);, scorpion fish insert ignore into journalissuearticles values(Scorpaena porcus); and stargazer insert ignore into journalissuearticles values(Uranoscopus scaber);. The present study was carried out between 01 January 2015 and 30 September 2016 in Sinop peninsula coasts of the southern Black Sea. The fish samples were captured trammel nets insert ignore into journalissuearticles values(32 mm, 36 mm 40 mm and 48 mm mesh size); in 0-15-30-45 meters depth ranges. The average length of common stingray, greater weever, scorpion fish and stargazer were established 48.2±4.98 cm 17.88±0.25 cm, 11.49±0.07 cm, 13.25±0.47 cm and respectively. LWR of the venomous fishes were determined W=0.0028L3.2187 insert ignore into journalissuearticles values(n=12, R2=0.97);, W=0.0287L2.5776 insert ignore into journalissuearticles values(n= 181, R2=0.93);, W=0.0245L2.9050 insert ignore into journalissuearticles values(n=808, R2=0.98); and W=0.0181L2.9398 insert ignore into journalissuearticles values(n=779, R2=0.98); and respectively. Positive allometric growth for common stingray and negative allometric growth for greater weever, scorpion fish and stargazer were obtained insert ignore into journalissuearticles values(t-test, p < 0.05);.
