Abstract

Seagrass ecosystems services in the coastal waters are included as primary producers, nutrient recycler, bottom stabilizers, sediment traps, and erosion barriers. Gleaning fisheries in seagrass bed in Mokupa waters could cause damage on seagrass, that can be marked by changes in seagrass cover. The purposes of this study were to identify the types of seagrasses and to determine the health condition of seagrass bed ecosystem in Mokupa waters. The research method used in this study is quadrat transect method. Data collection was carried out by laid three transects (100 m) with distance between each transect was 50 m. A square frame (50×50 cm2) which is divided into 4 squares is placed on the right side of the transect, with 10 m distance between frame. This study found four types of seagrasses, namely Enhalus acoroides, Thalassia hemprichii, Halodule pinifolia and Halophila ovalis. E. acoroides have the highest percentage cover (16.19%) followed byT. hemprichii (6.91%), H. pinifolia (4.50%) and H. ovalis (1.56%) respectively. Seagrass cover in the study area is considered medium (26-50%) while the health condition was poor (29.25%).

沿海水域的海草生态系统服务包括初级生产者、营养循环者、底部稳定者、沉积物捕集器和侵蚀屏障。在Mokupa水域的海草床上收集渔业可能会对海草造成损害，这可以通过海草覆盖的变化来标志。本研究的目的是确定木库帕海域海草的种类和海草床生态系统的健康状况。本研究采用的研究方法为样方法。数据采集通过铺设3个样条(100 m)进行，每个样条之间的距离为50 m。样条的右侧放置一个正方形框架(50×50 cm2)，分为4个正方形，框架之间距离为10米。本研究发现了四种海草，分别是Enhalus acoroides、Thalassia hemprichii、Halodule pinifolia和Halophila ovalis。螨类的覆盖率最高，为16.19%;恙虫病(6.91%)、松叶恙虫病(4.50%)、卵圆恙虫病(1.56%);研究区海草覆盖率为中等(26-50%)，健康状况较差(29.25%)。
