| dc.description.abstract | The Aek Boruan “and Aek Bontar River Watersheds (DAS) are 28.15
kilometers long and are located in the upstream. In the middle part of the
watershed, anthropogenic activities such as sand dredging, agriculture, and
bathing, washing, and toileting (MCK) occur. To determine the diversity of fish
species, abundance, diversity index, and dominance index were used to assess
diversity. Furthermore, the XLSTAT application was used to analyze the
relationship between diversity and waters in the Aek Boruan and Aek Bontar
Rivers. This study aims to identify the types of fish in the Aek Boruan and Aek
Bontar rivers. Furthermore, the second objective is to determine how the
physicochemical parameters in the two rivers correlate with the diversity of these
fish species. This quantitative descriptive study used purposive sampling as
research stations. In addition, physicochemical parameters of the water were
measured, including temperature (°C), pH, DO, depth, clarity, and current
velocity. The results of the study show a structure of eight species and six families
with moderate diversity. The results of the study indicate that fish species diversity
in the Aek Boruan and Aek Bontar Rivers is positively correlated with physical’
parameters, particularly depth, and chemical parameters, specifically DO, with a
very weak interpretation. Conversely, parameters such as temperature, pH, depth,
and brightness” are negatively correlated with fish species diversity, with a very
weak interpretation.. | en_US |
