摘要：The aim of the present study was to estimate some population parameters of red mullets caught in Central Black Sea. Average length of the sampling size that is composed of 699 individuals was found to be as 11.75 ± 0.111 and their average weight to be as 17.91 ± 0.507 gr. W = 0.0107 L 2.9717 was used to estimate the length-weight relationships. Asymptotic length (L∞) among the parameters of the growth equation was calculated as 20.15 cm whereas growth coef-ficient (K) was found to be as 0.33. Survival rate (S) was 0.28, real mortality rate (A) was 0.72, natural mortality rate (M) was 0.68, fishery mortality rate (F) was 0.60 and enterprise rate (E) was estimated to be as 0.47 In this survey, we search about the abundance and distribution of Gobiidae larvae in Izmir Bay between the years 2000-2004. For this purpose, seasonally obtained the ichthyoplankton sam-ples from 8 stations identified in the inner, middle and outer parts of the bay aboard the K. Piri Reis research vessel. They were shot horizontaly with a Hensen model zooplankton net which has a 200 μm mesh-opening and is 55 cm in diameter. We obtained 1210 larvae/10m³ through-out the survey and identified 4 species of Gobiidae family. These species; Gobius niger Lin-naeus, 1758, Gobius paganellus Linnaeus, 1758, Pomatoschistus minutus (Pallas, 1770) and Pomatoschistus microps (KrØyer, 1938), respectively. G. niger was found to be dominant in Izmir Bay.
