“…Although, the difference in abundance and biomass of total fouling on the panel surfaces were not statistically significant, those of the horizontal panels have shown to support more fouling organisms (taxon richness, abundance and biomass) than of the vertical ones. The same observation was formerly reported by Ghobashy and El-Komy (1981a) in Lake Timsah, Suez Canal. Studying a similar topic in Middle Harbour, Australia, Glasby (2000) mentioned that effects of orientation on serpulid Hydroides elegans (principal fouler in the present study) and H. ezoensis were obvious for sandstone and concrete panels (with horizontal>vertical).…”

“…Stachowitsch et al (2002), working on fouling at offshore oil platforms (Abu Dhabi, southern Arabian Gulf), mentioned, however, that both the number of individuals and the total biomass tended to decrease with depth. Ghobashy and El-Komy (1981a) reported that the uppermost two meters were the most populated panels in Lake Timsah, Suez Canal. Aleem (1957), likewise, concluded that the panels nearer to the bottom support less growth than those higher up, due to the scouring effect of bottom sand in deep waters.…”

“…Only a few studies gave some observations about the influence of orientation, including Ghobashy (1976) in the Eastern Harbour of Alexandria, and Ghobashy and El-Komy (1981a) in Lake Timsah, Suez Canal. They indicated that the fouling organisms prefer to settle on the underside of horizontal surfaces rather than on the vertical surfaces.…”

The present work aims to study the influences of depth and orientation on the distribution of macrofouling communities at shallow coastal harbour (Abu Qir Harbour, Egypt, southeast Mediterranean Sea). Fouling communities were collected for a period of one year (June 2006-May 2007) by suspended white test panels at different depths (from 0.5 m to 5.5 m) in two directions (horizontal and vertical). Panels were submerged on short-term durations of 30 days. Every panel was studied (on both sides) for species composition and abundance of fouling taxa, as well as the total biomass of the community. Data of fouling assemblages obtained were analysed using ANOVA and non-parametric tests in order to compare the variations of assemblages with season, depth and direction. In general, the abundance and biomass of fouling community were significantly related to the season and depth rather than orientation. Although comparison of fouling assemblages (for direction) between the panel surfaces were not statistically significant; the horizontal panels, in particular, support more fouling organisms.

“…This result agrees mostly with that recorded in fouling experiments (Crisp. 1974 andGhobashy &EL-Komy 1982) in that density of settlements increase with substrate surface areas and with the duration of exposure. In the present work it was reported that most epifoulers in both populations, tended to settle on dorsal sides of oyster shells except the tube worms which preferred the ventral ones.…”

E pifouling assemblages. on pearl oyster shells in onshore and offshore'oyster beds, at Qatari water, Arabian Gul£ were investigated in relation to oyster size and flesh growth. Onshore oysters had great biofoulers and low growth parameters than offshore ones. In both beds, biofoulers were dominated by sponges, thorny oysters, polychaetes and red algae. Of these, the serpulid worm (Serpula vermicularis) and the thorny oyster (Spondylus marisrubri) were the most pronounced particularly in onshore oysters. Density of biofouler settlement increased with shell surface areas. Most biofoulers tended to settle on dorsal side of the pearl oyster except the tube worms which preferred the ventral side.
