If the primary goal of artificial reef construction is the creation of additional reef habitat that is comparable to adjacent natural rocky-reef, then performance should be evaluated using simultaneous comparisons with adjacent natural habitats. Using baited remote underwater video (BRUV) fish assemblages on purpose-built estuarine artificial reefs and adjacent natural rocky-reef and sand-flat ...
We compared catches of settlement-stage reef fishes in light traps attached to underwater speakers playing reef sounds with those of silent traps during a summer recruitment season at Lizard Island, Great Barrier Reef, Australia. Of the total 40191 reef fishes we collected, significantly more (67%; Wilcoxon and Binomial tests: p< 0.001) appeared in the traps with broadcast reef noise. Traps dep...
Artificial reefs are effective measures to improve the marine ecological environment and increase fishery production. However, there several geometries being investigated nowadays their setup, including spacing between groups of them, can provide dissimilar effects on hydrodynamics. To enhance understanding this topic, in paper, focus is mainly M-Type artificial that will be adopted Juehua Isla...
Fisheries-independent surveys are commonly used to create indices of relative abundance. If properly designed and calibrated, these may also be estimate absolute Here, we demonstrate the efficacy this approach by estimating abundance red lionfish ( Pterois volitans), gray triggerfish Balistes capriscus), snapper Lutjanus campechanus) across an extensive network artificial reefs using camera cou...
Coral reefs provide a number of ecosystem services including coastal defense from storms, the generation of building materials, and fisheries. It is increasingly clear that the management of reef resources requires an ecosystem approach in which extractive activities are weighed against the needs of the ecosystem and its functions rather than solely those of the fishery. Here, I use a spatially...
The Persian Gulf is northern part of the ROPME Sea Area (RSA), and is semi-enclosed shallow sea which located in subtropical climate. Measuring is 1000km in length, varying in width 60-340km, and average depth is about 35m and maximum depth is 105m. This research was carried out during 2005-2010 for reviewing the corals status and determination of coral reef habitats distribution in the Persian...
