Outbreaks of A. planci cause serious damages to coral reefs. In contrast, it is less known that A. planci also consumes zoanthids. We observed A. planci preying on a reef covering zoanthid, Palythoa tuberculosa at night between August and September 2010, in the outer reef fl at of Mizugama, Okinawa. Several individuals aggregated on P. tuberculosa colonies (Fig. 1). The individuals were relatively small, approximately 5-10 cm in radial length. Acanthaster planci preying on P. tuberculosa were also observed in the daytime in October 2010 in Lyudao, Taiwan. According to Gleibs and Mebs (1999), A. planci predates upon Palythoa in the South Pacifi c, which may indicate this is a usual event. Interestingly, at Mizugama, no individuals were detected on neigh boring Acropora spp. colonies that probably had recruited after the mass bleaching event of 1998. From additional observations in April 2011, neither A. planci individuals nor feeding traces of them were detected on P. tuberculosa colonies, suggesting that preying on P. tuberculosa occurs seasonally. At Mizugama, P. tuberculosa breeds in August (Hirose et al. 2011). In fact, pink-colored mature eggs were observed within colonies damaged by A. planci feeding. It is possible that A. planci preys on P. tuberculosa to obtain a more nutritious food, their eggs.","PeriodicalId":118057,"journal":{"name":"Galaxea, Journal of Coral Reef Studies","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127530001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The evaluation tools used were fishery dependent (i.e. focus group discussion) and independent (i.e. fish census, benthic assessment and crownofthorns density) samplings. All sampling was conducted at least twice for one year. In all sites, COTs densities were just above the alarming stage (~1 individual.250 m). Aundanao MPA showed a positive feedback system by supporting the spillover effect. There is high density of sexually mature fish (<30 cm Total length and significantly higher fish biomass estimates of target species (16 mt km) inside than outside the MPA. The relatively small catch (20 mt year) from fishing adjacent to the MPA is attributed to the limited capacity of the core zone (only 3 ha) to support the fishery. It also serves as a refuge site for small pelagic fishes (i.e. ox-eye scad, Selar boops) that aggregate along the slope. In contrast, the Coral Garden MPA had very low fish biomass (4.0 mt km) and only a couple of sexually mature individuals both inside and outside the sites. Intermittent guarding which have resulted to occasional poaching in the notake area was one of the reasons. Further, a newly introduced fishing gear bintol (modified lift net), for subsistence targeting damselfishes has started to operate near the area. This is an evidence of a lesser density of targeted food fish to catch. Coral Garden MPA has shown that the rate of extraction exceeded the pre sumed turnover rate of the associated reef fish standing stock suggesting an overfishing of the area.","PeriodicalId":118057,"journal":{"name":"Galaxea, Journal of Coral Reef Studies","volume":"116 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126390359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
