In this study, changing of catch per unit effort (CPUE) and length composition of bluefish (Pomatomus saltatrix Linnaeus, 1766) caught in southern Black Sea was monitored during the period of 8 weeks in October and November 2012. A total of 2255 kg bluefishes were captured by pelagic trawl at the end of the 32 hauls. The length-weight relationships of bluefish were established as W=0.0037L3.3067 (positive allometric growth). The catch per unit effort (CPUE) and mean length were fixed as 14.43 kgh-1 and 17.5±0.03 cm, respectively. Differences between CPUE values of each weeks were found statistically significant (P<0.05). The highest and lowest mean total lengths of bluefish were determined 18.9±0.08 cm (October) and 16.2±0.10 cm (November) respectively. It is determined that changing in size composition of the caught fishes is depending on time. Also, it can be expressed that fishing period affects catch per unit effort in bluefish fisheries.
