The distribution of reef fish in Ternate Island, North Maluku, Indonesia

Abstract

Reef fish is a constituent component for coral reef ecosystems, so it is very important to identify the distribution of reef fish species. This study aims to assess the number of reef fish species, diversity, abundance, recruitment, and frequency of size. The results showed that the number of reef fish species on Ternate Island was 42 families, 109 genera, and 265 species. The high level of diversity is 3.57 - 4.79 with an abundance of 8 - 28 ind.m−2. The addition of new individuals to the population both due to reproduction and migration of 16.26 - 51.72%, the size-frequency of reef fish based on the size of the first time the gonads mature (Lm) is 45.00 - 70.00% of the total population of reef fish.
