Abstract

The study aimed to identify species of reef fishes, to obtain indexes of diversity  and dominance, eveness and to analyze the comparison of communities between the two study sites by Sorensen similarity index. Data was gathered in-situ with underwater recordings at a depth of 6 meters assisted by diving apparatus, and using fish visual census method. Subsequent data were identified using  fish identifikaction guide and WoRMS (Word Register of Marine Science) online identification applications. The number of species and specimens of reef fishes from each study site after bein identified were then analyzed  the diversity, dominance and similarity of the community between the two study sites. The coral reef fishes identification results that obtained from each study site  were:  20 families, 86 spesies and 362 specimen at  Malalayang beach, and 15 families, 55 spesies and 217 specimen at Meras beach. The value of the calculated index o community structure obtained by H’ 3.42 (Malalayang) and 2.91 (meras) has been shown the ecological condition of coral reef ecosystem which is still stable even though diversity is moderate, but inversely with low dominance value (D=0.08). The coral reef fishes in both study sites were very diverse and there was no dominant species. Eveness of community between two study sites high.The result of community similarity analysis using Sorensen Index was 49 % (<50 %) indicates that there was no community similarity of coral reef fishes between Malalayang Beach and Meras Beach which was allegedly caused by natural factors and or anthropogenic one in both research sites.Keywords : coral reef fishes community, diversity, dominance, community similarity

Abstract

Generally, this study was intended to examine the problems or implementation of turtle conservation in Talise, Gangga and Bangka Islands and specifically with a number of objectives to: know the introduction of sea turtle, to know sea turtle fishing and turtle exploitation, to know the knowledge of the people about turtle as a protected animal. Survey results on Talise Island, Gangga and Bangka showed that people who had seen turtles directly: Talise Island 94%, Gangga 58%, and Bangka 92%. Local residents of Talise, Gangga and Bangka Islands know well the turtles even see directly in their habitat and spawning time. In Talise, Gangga and Bangka Islands,  turtles are still commonly caught, traded and consumed by local people.  People's awareness about turtles as protected animals is lacking.  Keywords: Turtle, Talise Island, Gangga and Bangka
