Review of Artificial Reefs in Taiwan: Emphasizing Site Selection and Effectiveness
Abstract:Nineteen artificial reefs were constructed in the coastal waters off Taiwan and Peng-hu Islands in the past decade.
Systematic studies on the site selection, the configuration and construction materials of the reef blocks, the biological community succession on the artificial reefs, and the economic evaluation of the reef fisheries were performed, from which several conclusions were reached: (1) a preferable reef site is shielded from strong current, away from natural reefs, and in waters not deeper than 30 m; (2) an effective artificial reef should always be constructed of long-lasting materials, established in collective piles, and provide enough shielding spaces for different sizes of fishes; and (3) modulated by surrounding environmental conditions. Two types of sessile organism communities were developed on artificial reefs, an autotrophic community dominated by algae and a heterotrophic one dominated by sessile invertebrates. The behavior of some fish species associated with artificial reefs is described. The effectiveness of artificial reefs for natural resources preservation, habitat reconstruction, and nursery of coastal water fisheries was confirmed.
