  1. Locate artificial reefs near aquaculture systems to benefit from nutrient run-offs

    A controlled study in 1999–2000 of two artificial reefs in an area of sand and seagrass in the Gulf of Aqaba (Gulf of Eilat), Red Sea, Israel and Jordan (Angel et al. 2002) found that, after one year, an artificial reef deployed at an aquaculture site did not appear to develop a higher biomass of sessile invertebrates compared to an artificial reef deployed at a site without aquaculture activity. Data were not statistically tested. Biomass of invertebrates varied between the two reefs following deployment and tended to be similar after a year (approximately 700 kg/reef). In March 1999, two artificial reefs (8.2 m3) were deployed at 20 m depth: one at a fish farm, and another at a site 500 m west of the fish farm without aquaculture activity. Each reef held multiple 30 × 45 cm sample plates used for invertebrates to colonise. Three plates were sampled monthly from each artificial reef, photographed, dried, and the biomass of attached invertebrates recorded.
