Diversity of coral reef fish in the coastal water of Spelman Straits, Southeast Sulawesi

Abstract

Spelman Strait is one of the potential reef fisheries. This study aims to examine the potential of reef fisheries in the Spelman Strait. The data used in this study are primary data to determine the abundance of reef fish and the use of PaST (Paleontological Statistics) tools to assess diversity, Evenness, wealth, and dominance indices. The results showed that live coral cover from all observation stations was 37.71%. The abundance of reef fish has been under pressure, the diversity index still has good but some families experience threats, the Evenness index value also still shows an even distribution but there are several families threatened, the wealth index still describes good species wealth, but the distribution is uneven, while the dominance index value illustrates that the condition of the coral reef ecosystem is under pressure. This condition is caused by destructive fishing so that the existence of some economically important targeted fish is threatened.
