Abstract

Fish as a wealth of biological and germplasm as well as the constituent of ecological systems on a water. One of the main issues threatening fish biodiversity is the problem of environmental pollution from the company's waste into the river. Need a study that can analyse the impact of atropogonic on the presence of fish in the concept of biodiversity. Monitoring the easiest impacts of environmental pollution is to observe the biodiversity of fish as a constituent ecosystem. Based on the known literature that fish bidiversities can be used as bioindicators to determine the level of environmental pollution. This research aims to determine the condition of fish biodiversity in the region as well as the company as environmental health monitoring efforts of Belawan River. Research is conducted in an exploratory, where fish sampling station is determined through pusposive sampling method. Fish sampling using the capture equipment: fishing rod, gill nets, stocking nets, and fish trap. Data analysis using Microsoft Excel program 2010. The results of the study gained an amount of catch-up of 151 individuals derived from a total of 22 species of fish. Biodiversity Index (H’) on Station 1 (2,46), Station 2 (2,64), and Station 3 (2,45); Uniformity index (J') on Station 1 (0,82), Station 3 (0,88), and Station 3 (0,82); Dominancy Index (C) on Station 1 (0,05), Station 2 (0,06), and Stasiun3 (0,04).

Abstract

Slender walking catfish (Clarias leiacanthus) is a type of wild catfish that has been increasingly difficult to find in nature. This catfish is most wanted as fish consumption and the price is quite high, because of its distinctive and savory meat flavor. The natural habitat of slender walking catfish in general is clear and unpolluted waters. One of the habitats of slender walking catfish found in the Swimming Niagara Sirao-rao, Desa Bandar Tinggi, Labuhanbatu Regency. The study of the natural habitat characteristics of C. leiacanthus in this region has never been done. The purpose of this research is to know the chemical factors of water that become natural habitat of C leiacanthus. Analysis of water samples related to pH, DO, BOD, and COD was conducted in the Laboratorium Balai Riset dan Standardisasi Industri Medan, used method AAS. Results of the analysis showed pH (6,5), DO (6,9 mg/L), BOD (3,27mg/L), and COD (8,26 mg/L).
