Abstract

The utilisation of seagrass area by fishes and macro invertebrates were studied at Sulaman Lagoon. Sampling of fishes and macro invertebrates from both seagrass and non seagrass area was done using a beam trawl. A total of 38 species of fish and 9 species of macro invertebrates were caught at the seagrass area compared to only 10 species of fish and 9 species of macro invertebrates caught at the non seagrass area. Some of the common occurring fishes and macroinvertebrates caught such as Lutjanus russellii, Gazza minuta, Leiognathus splendens and Thalamita crenata shows a smaller size compared to their adult size indicates that these specimens are still at their juvenile stage of life. These juvenile species uses the seagrass area as their nursery ground to grow up before migrating to another habitat. Besides that, the seagrass area can also act as a feeding ground for these organisms. The gut content of the specimens shows that they are dependent on the source of food found at the seagrass area. Some of the fishes and macro invertebrates caught such as Archamia buruensis, Apogon amboinenses and Thalamita crenata are found to be carrying eggs. Although most of the specimens which are carrying are caught at the seagrass area, however it is not clear that the seagrass area is used as their spawning ground or the adjacent areas. This study has proven that the seagrass area is an important area which plays various roles and functions for fishes and macro invertebrates.
