| 内容記述 | Spawning aggregations of coral reef fishes are particularly vulnerable to fishing since only conspecific individuals gather at specific sites in restricted seasons and lunar phases. Since capturing spawning aggregations leads to significant negative impacts for both local stock and reproductive success, protection of spawning aggregations has been an urgent need recently for coral reefs all over the world. Furthermore, conservation of habitat in the non-spawning season is also essential for species that form spawning aggregations since habitat loss at their home ground would also lead to a reduction in their population. In the present paper, the focus is on a coral reef grouper species (Epinephelus ongus), that is a very important fishery target and forms spawning aggregations in an Okinawan coral reef. Effective coral community restoration is discussed to establish a sustainable fishery of the species. This author’s previous studies have shown: (1) their home ground was several kilometers around the spawning ground; (2) their home range was very limited around a coral colony during non-spawning periods; (3) juveniles preferentially used corals with fine structure (e.g. bottle-brushed acroporid corals) whereas adults were mainly found at corals with coarse structure (e.g. massive corals and staghorn acroporid corals); and (4) very precise returning ability was observed after spawning migration (i.e. species would return to the coral colonies that were used before the spawning migration). These results suggest that: (1) conservation of the coral community around the spawning ground is indispensable; (2) coral species that are preferentially used by E. ongus should be selected for coral community restoration; (3) the area several kilometers around the spawning ground should be the proposed area for coral community restoration. Since the spawning ground of the species has already been assigned as a marine protected area, coral community restoration around the spawning ground would be useful to enhance the E. ongus stock. | |||||||||||
