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