Published as: Fish Colonization of an Artificial Reef in the Gulf of Eilat, Northern Red Sea. | Technique: Substrate Addition - Artificial reef | Disturbance addressed: General degradation | Genera: n/a | Method: An artificial reef structure was placed 300m offshore at a depth of 22–24 m, at a distance of 20–50m from an existing, severely damaged natural reef. The artificial reef consisted of seven metal structures: a circular bellows; a cylinder shaped heat exchanger unit, two metal construction beams, and four amphibian vehicles. Fish communities were surveyed for 2 years. | Post-restoration monitoring: 24 months | Authors' conclusion: The colonization of fishes was initially rapid and a total of 94 species was recorded. In the first seven months, a gradual increase in the number of species was observed, after which it leveled off. | Lessons reported: The low complexity of the major components of the artificial reef, in addition to its location on a muddy, silty substrate, resulted in a constant cover of fine grain particles which presumably discouraged settlement of invertebrates and small cryptic fish species on the artificial reef. | This record was compiled from a published source and has not been confirmed by the organisation that carried out the work. No contribution to the condition index is recorded: the source reports survival of transplanted material, which is not a measure of ecosystem condition.

Recorded result

No result recorded yet. A result is recorded when the project moves to Paused, Completed or Discontinued.

A variable shows "pending" instead of a contribution when no domain area has been set for it yet — the share of the world a project touched cannot be computed without one. The health percentages are accurate regardless.
