KEANEKARAGAMAN MAKROZOOBENTOS DI PERAIRAN DANAU KELUBI KECAMATAN TAYAN HILIR KABUPATEN SANGGAU
ABSTRACT: Kelubi lake has an
area of ?? 220 ha and high puddles influenced by rainfall. The research aimed
to know macrozoobenthos diversity and the quality of Kelubi lake waters.
Determination of five sampling stations based on different environmental
setting. Macrozoobenthos samples were taken three times at each station by
Ekman Grab and identified in the Zoology Laboratory of the Faculty of
Mathematics and Natural Sciences of Tanjungpura University Pontianak.
Macrozoobenthos research results obtained in the waters of Lake Kelubi four
genera namely Chironomus, Dasyhelea, Dixella and Limnodrilus. Value abundance
of macrozoobenthos in Lake Kelubi ranged from 44.44 to 355.55 Ind/m2. The
diversity index (H) of the highest macrozoobenthos obtained at station IV of
355.55 Ind/m2 and lowest at station I of 0.5004 Ind/m2. The macrozoobenthos
diversity in Kelubi lake was low to moderate. The average of evenness index (E)
of macrozoobenthos was 0.8650 which indicates high evenness, while the average
of Simpson dominance index (C) wason the average of 0,4950 which in considered
low dominance of macrozoobenthos. The result of Pearson correlation test shows
that depth, temperature, transparency, organic substrate significantly affect
the diversity of macrozoobenthos in Kelubi lake. Kelubi lakes classified in
moderate pollution levels.
