The fish samples and water were collected from the river in the early and end of June to represent temporal variation. Simultaneously

Mangrove plays the importance of roles for the small island sustainability, both physically and ecologically. In the high-risk Pacific Ocean’s islands, small islands in Biak face typhoons, earthquakes, high waves, and tsunami effects. The study was conducted at 100 10mx10m-quadratic-plots scattered on seven small islands in Biak-Numfor Regency. Research objectives were to investigate the mangrove community

Filimanus perplexa is among fish species with high economic value. It has a flattened body shape and yellowish body color. Another characteristic of F. perplexa is seven free filaments on the pectoral fin whose exceeds the anal fin. These species do not show sexual dimorphisms. Therefore, a taxonomic study is needed to distinguish male and female individuals of Kurau fish. Differences between male

The research design was Randomized Completely Block Design. The

Nereis sp. (Polychaete) belongs to the Nereidae family that lives as benthic organisms in estuarine. The high level of amino acid and unsaturated fatty acid in Nereis sp. is potentially used as a nutrient in prawn feed. These compositions increase the quality of prawn gametes and larvae. However, there is still less information about the nutrient composition of Nereis sp. in the Jeruklegi area. Therefore

There was a unique brackish water ecosystem and affected a chance in the plankton composition at lagoon and riverside in Segara Anakan Cilacap.
