dc.description.abstractA total of 988 Atlantic stargazer, Uranoscopus scaber, was collected monthly by bottom trawlers from the Eastern Black Sea. Reproduction characteristics such as sex composition, maturity stage, length at first maturity, spawning time, reproduction period, fecundity, length-weight relationships and condition factor were investigated. The percentage of females, males and indefinite were 66.90, 29.65 and 3.44%, respectively. The female:male sex ratio was 2.26:1 (P < 0.05). Mean condition factors of females and males were 0.991 and 0.956, respectively. Taking into consideration of gonado-somatic index (GSI) values and egg diametre, it was determined that reproduction occurred in July and August. The first maturity age for female and male was 2 and the first reproduction lengths were 11.76 and 13.75 cm for male and female, respectively. The exponentially relationships between fecundity and total length was F = 0.2283TL(3.6314) (R-2 = 0.53) and the linear relationship between fecundity and fish weight was F = 118.9W - 1788.8 (R-2 = 0.34). The average egg number that a female spawned at once was 16185 +/- 1455. The average diametre of mature eggs was 1.55 +/- 0.05 mm. There were significant differences between sexes in monthly condition flictors (P < 0.01).
