The influence of nature and human activities greatly affects the distribution and diversity of algae. This study was conducted to determine the species diversity, density, phosphate concentration, and algae utilization as a food material found on the island of Ambon. The sampling location was on Ambon’s island in three locations, i.e., Tantui, Hative Besar, and Allang. For 100 m, line transects were laid perpendicular to the shore at every station. For every of the transect line, four 50 cm×50 cm quadrat was placed randomly. There was 18 genus of seaweed. Of the 22 species, 11 species from Rhodophyta (50.0 %), 5 species from Phaeophyta (22.73%), and 6 were from the class of Chlorophyta (27.3%). The highest value density is village Hative Besar that is 1219.9 gr.m −2 is from the Chlorophyta group ( Enteromorpha prolifera ), Tantui is 986 gr/m2 from the Rhodophyta group ( Gracilaria ), and Allang that is 756.18 gr.m −2 from the Rhodophyta group ( Acantophora ). The maximum concentration in Allang is 0.19 mg.L −1 , concentration in Hative Besar is 0.18 mg.L −1 , while the minimum phosphate concentration is 0.15 mg.L −1 at the Tantui location. The types of algae that can be used as food sources include Gracilaria sp., Caulerpa sp., Sargassum sp, Gelidium sp., and Ulva sp.
