Struktur Komunitas Perifiton Pada Keramba Jaring Apung Perairan Waduk Koto Panjang Kabupaten Kampar Provinsi Riau
Periphyton is a type of algae that commonly inhabit the surface of immersed objects. A research aims to understand the periphyton community (types and abundance) in the floating-net cage in the Koto Panjang Dam has been conducted from May to June 2015. Samplings were conducted 3 times in 3 stations, namely St. I (Tanjung Alai, 200 cages), St. II (Pulau Gadang, 500 cages) and St. III (Dam Site, 700 cages). Periphyton samples were taken by scraping the surface of the immersed cage using tooth brush (10x10 cm2). Periphyton collected were then preserved in lugol 1 % 2-3 drop/40 ml and then was identified based on Hiroyuki (1977), Yunfang (1995), Sachlan (1982) and Bellinger and Sigee (2010).
Result shown that there were 49 periphyton species present and they are belonged to 6 classes, namely Bacillariophyceae (15 species), Chlorophyceae (18 species), Chrysophyceae (1 species), Cyanophyceae (13 species), Dinophyceae (1 species) and Xanthophyceae (1 species) and the periphyton abundance was 28,841-77,666 cells/cm2). In general, the H’ was 4.689-4.981; C was 0.040-0.053 and E was 0.889-0.918. The water quality parameters are as follows: temperature was 30-31 0C; brightness was 100.5-139.0 cm; turbidity was 1.50-2.68 NTU; pH was 5-6; DO was 5.6-6.0 mg/L; free CO2was 3.9-4.5 mg/L; nitrate was 0.045-0.050 mg/L and phosphate was 0.035-0.041 mg/L. Based on periphyton community it can be concluded that theaquatic environment in the Koto Panjang Dam balance.
