Age, growth and mortality rates of discard species (Uranoscopus scaber, Neogobius melanostomus and Gobius niger) in the Black Sea

Uranoscopus scaber, Neogobius melanostomus ve Gobius niger Türkiye balıkçılığında ekonomik olmayan balıklar olarak adlandırılmakta ve ıskarta edilmektedirler. Bu çalışmanın örnekleri Karadeniz kıyısında kullanılan dip trolü, uzatma ağı ve gırgır ağları ile avlanmıştır. Bu çalışmadan elde edilen sonuçlar, Uranoscopus scaber ve Gobius niger türünün yaşlarının 0-V arasında, Neogobius melanostomus türünün ise 0-VII yaş arasında değiştiğini göstermiştir. Von Bertalanffy büyüme parametreleri, toplam ölüm oranları, doğal ölüm oranları ve balıkçılık ölüm oranları ise her tür için ayrı ayrı hesaplanmıştır.

Karadeniz'de ıskarta türlerin (Uranoscopus scaber, Neogobius melanostomus ve Gobius niger) yaş, büyüme ve ölüm oranları

Uranoscopus scaber, Neogobius melanostomus and Gobius niger are called non-commercial fish species and also caught as discarded in Turkish fisheries. Samplings were carried out by bottom trawl, gillnet, purse seine net operations in the Turkish Black Sea coasts. The results of the study showed that age of these species were 0-V ages for Uranoscopus scaber and Gobius niger, and 0-VII ages for Neogobius melanostomus for both sexes. The von Bertalanffy growth parameters, total mortality rate (Z), natural mortality rate (M) and fishing mortality rate (F) were calculated for each species separately.
