Abstract

This study examines the impact of invasive fish species in Indonesia, which is an important issue in efforts to maintain the sustainability of aquatic ecosystems. This study aims to identify existing non native fish species and evaluate their impact on local biodiversity. The methods used included a literature review and field surveys to collect data on the distribution of invasive species. The results showed that invasive species not only threaten the existence of native species, but also disrupt the overall balance of the ecosystem. The findings highlight the importance of effective management to prevent the further spread of invasive species, as well as the need for increased public awareness of their negative impacts. This research is expected to contribute to the development of better aquatic resource management strategies.

Abstract

Estuaries and coastal waters are heavily influenced by anthropogenic activities and environmental factors, which can lead to ecosystem degradation, increased nutrients, and the risk of eutrophication. Kendari Bay, with its complex hydrodynamic conditions and various human activities in the vicinity, requires an analysis of the distribution of nutrients and chlorophyll-a (chl-a) to estimate the potential for eutrophication and its impact on aquatic ecosystems. This research was conducted in March-May 2023 at six stations in Kendari Bay. The distribution of nutrients in Kendari Bay revealed a varied pattern, with DIN concentrations higher in the “neck area” or narrow parts of the bay, phosphates more concentrated in the inner part due to slow water flow, and silica more abundant in estuaries because it comes from weathering rocks carried by river flows. Chl-a concentration tended to correspond DIN pattern, suggesting that phytoplankton growth was more influenced by nitrogen nutrients than phosphorus nutrients, as supported by an N:P ratio of less than 16. Overall, Kendari Bay was classified as mesotrophic with a relatively uniform trophic level due to morphological and hydrodynamic characteristics that narrow towards the sea and a low flushing rate. A comprehensive approach to managing human activities from upstream to downstream must be performed effectively to protect the bay area from eutrophication and environmental decline due to excessive nutrient runoff from land-based activities.
