Abstract

The coastal area of Negeri Latu, West Seram Regency, possesses a relatively high marine biodiversity and is a vital natural resource for the local economy, particularly in fisheries. However, increasing human activities around the coastal zone, such as the disposal of domestic waste, garbage, and industrial effluents, have exerted significant pressure on the quality of the marine environment. This study examines the utilization of aquatic biota as early pollution indicators in the coastal area of Negeri Latu, West Seram Regency. This research employs a descriptive quantitative approach. The coastline of Negeri Latu spans approximately 900 meters, with nine transects established perpendicular to the shoreline, each spaced 100 meters apart. Ten observation plots (1×1 m) were placed alternately along each transect at 10-meter intervals. Marine biota were observed, quantified, and identified to determine their species. The analysis results indicate that the pollution status in these waters falls under the Moderately Polluted category. This classification reflects a significant disturbance to water quality, although it has not yet reached severe pollution. The decline in water quality is attributed to various anthropogenic factors, particularly the local population’s high volume of waste disposal into the sea. The waste includes both organic and inorganic materials, contributing to marine environmental degradation through physical (e.g., water turbidity and discoloration), chemical (e.g., pH changes, increased levels of heavy metals and toxic compounds), and biological (e.g., reduced diversity and abundance of marine organisms) means.

Abstract

The adhesion of green mussel spit is highly correlated with depth. This study aims to establish the correlation between the depth and duration of observation with the abundance of green mussel spat (Perna viridis) in the coastal waters of Waiheru Village, located in Inner Ambon Bay. This study was undertaken utilising three floating net cages (KJA) possessed by local fishermen. The KJA utilised in this investigation had dimensions of 2.0 x 2.5 metres. Each KJA is equipped with 4 threads of hanger rope, resulting in a total of 12 hangers. Each rope hanger is positioned at specific depths, specifically at depths of 3, 6, and 9 metres. The net is 40 cm by 40 cm. Observations were conducted on days 2, 4, 6, 8, 10, 12, and 14 after the nets were strung. The findings indicated that the depth and duration of observation significantly influenced the quantity of green mussel spat. Specifically, more spat was observed compared to other days, suggesting a stronger attachment at that depth and observation period. Nevertheless, on the 10th day of observation, there was a surge in the quantity of green mussel spit.
