| dc.description.abstract | This study of Fish Diversity in the Bunga Beach, Batubara District, Medan City,
North Sumatra Province aims to study the diversity of fish species and their
relationship with physicochemical parameters in the Bunga Beach, Batubara District,
Medan City, North Sumatra Province. Sampling was carried out at three different
stations. The results of the study found 10 fish species consisting of 7 orders, 7
families, and 7 genera. The highest diversity index was found at station III (2,00),
followed by station II (1,94), and the lowest at station I (1,88). Principal Component
Analysis (PCA) showed that brightness, DO, and temperature had a strong positive
correlation with fish diversity, while pH, and salinity were negatively correlated.
Environmental factors such as industrial activities, habitat conditions, and water
quality play an important role in determining fish diversity and abundance at the
study site. The results of this study provide important information about the
condition of the Bunga Beach ecosystem and can be used as a basis for the
management and conservation of fishery resources in the area. | en_US |
