Structural complexity of seagrassbed including species composition and shoot density is argued to be animportant factor determining fish assemblages. However statistical verificationof such a relationship is possible only in areas with high species richness ofseagrass and fish assemblages which is observed in tropical waters. Materialfor this study was collected in three seagrass beds with different structure inInner Ambon Bay, Eastern Indonesia. This study provided evidence that higherstructural complexity of seagrass bed was related to the higher richness,abundance, and biomass of fish. However, lower structural complexity ofseagrass patch should not be underestimated because it provided different habitat forvarious stages of life in fish. Smaller fish preferred to occupy dense seagrass ofdominant pioneer small-sized species Haloduleuninervis and moved to the lesser dense bed of climax large-sized seagrassThalassia hemprichii and Enhalus acoroides with increasing theirsize. This finding is important for seagrass-fisheries management.
