| dc.description.abstract | This research was conducted in Belumai River, Deli Serdang District in Mei-June
2014. The aim of this research was to measure relative abundance, diversity,
uniformity and dominance of fish and the relationship with physical and chemical
factors of water. The method used in this research is “Puspose Random
Sampling”. Fisihing gear used for fish sampling is gill net, fishnet stocking and
fish rod. Data were analyzed descriptively and multiple regression analysis. This
research obtined 8 families, 12 genus, 14 species and 204 individual fish. Highest
relative abundance was Mystus gulio fish of 23,03% while the lowest was
Glossogobius giuris fish of 0,49%, diversity index obtained was 1,59, uniformity
index 0,78 and dominance index 0,26. Temperature was 28 – 29,75oC, turbidity
3,25 – 14,98 NTU, depth 0,78 – 2,58, flow velocity 0,18 – 0,77 m/sec, pH 5,9 –
7,2 and DO 1,81 – 5,02 mg/l. Regression results showed strong relationship
between components. It’s seen from the range of the coefficient determination
(R2) 0,866 – 0,9 | en_US |
