Artificial Reefs in Kuwait, Northern Arabian Gulf
Abstract:Three experimental artificial reefs, constructed from scrap motor car tires were deposited in 10 m of water off the southern Kuwaiti coast in May 1981. Each reef occupied a bottom area of approximately 25 m2. Two of the reefs were 0.8 m high and differed in the spacial arrangement of the tires used to build them. The third, a high profile reef, measured 2.4 m high. Nine surveys of the fish attracted to the reefs were carried out over the following 12 months. The nature and extent of invertebrate colonization was monitored using pre-weighed patches of motor car tires fixed to the tops of the reef tires.
At least 50 species of fish, representing 33 families were observed on the artificial reefs between May 1981 and April 1982. The species composition of the fish communities showed few differences between the three reefs. The high profile reef attracted a greater biomass of fish more rapidly than either of the two low profile reefs, although in terms of the outer surface area of each reef average standing crops were similar.
Sport fish made up 86% of the total standing crop of all the reefs, and over 50% of the fish biomass was accounted for by the grouper Epinephelus tauvina and by the barracuda Sphyraena jello. The high profile reef attracted more than four times the biomass of grouper than did either of the low profile reefs.
