The aim of this study was to determine the diel variations of the fish assemblages on artificial reefs on muddy and sea grass meadow areas of Western coast of Turkey (Aegean Sea). To determine the diel variations, visual census were conducted according to a time schedule (06:00-07:00, 12:00-13:00, 18:00-19:00 and 24:00-01:00) by SCUBA divers in August 2004. Counts were made as three replicates during each time period. A total of 27 fish species belonging to 10 families were recorded in DAR. At GÜAR, 27 fish species belonging to 13 families were recorded. The lowest species (3 in both sites) and individual numbers (4 in GÜAR and 9 in DAR) were recorded at night (24:00-01:00 period) observations in both sites while the highest numbers w...

Selectivity parameters were estimated using the indirect method proposed by Holt (1963). The optimum catch lengths of D. annularis in 18, 20, 22 mm mesh size were 10.08, 11.20, 12.32 and 15, 16.67 and 18.33 cm for S. flexuosa respectively. Overall selection factor and standart deviation were 5.60 and 1.86 for D. annularis, 8.33 and 1.21 for S. flexuosa respectively. In result, only the nets in 22 mm mesh size showed suitable selectivity for D. annularis. But, for S. flexuosa was found suitable all mesh size tested.
