Abstract

AbstractThe Bunter Lake is an oxbow lake that receive water from the Kampar River during the rainy season. As the water flew to the lake, many types of fishes may be entered the lake. On the other hand, when there is no water input from the river, the fishes were trapped in the lake and fish catching activities conducted may affects the population of the fish in general. The presence of fish coming from the river and the fishing activities in the lake may affects the biodiversity of the fish in general. To understand the biodiversity of the fish in the lake during the rainy season, a study has been conducted on July to August 2021.  Samplings were conducted 6 times, 3 times during the rain/ flood and 3 times when there was no rain. The fish was captured using gillnet, 0.5 and 3 inch mesh size. The fish captured were identified. Results shown that there were 18 fish species that were belonged to 6 families. There were family Cyprinidae (Thynnichthys polylepis, T. thynnoides, Barbodes schwanenfeldi, Rasbora argyrotaeina, Barbichthys laevis, Osteochilus hasselti, Puntius bulu, Oxygaster anomarula, O. melanopleurus, Hampala macrolepidota dan Amblyrhynchichthys truncates), family Bagridae (Mystus nigriceps, M. nemurus), family Siluridae (Ompok hypophthalmus, Phalacronotus apogon), family Eleotridae (Oxyeleotris marmorata family Notopteridae (Notopteridae boornensis) The diversity index value (H') was 2.12, the dominance index (C) was 0.36 and the uniformity index (E) was 0.70. These data indicate that the diversity of fish in the Bunter Lake was   moderate. As the dominance index value (C) as well  the uniformity index value (E) were relatively low , the environmental condition of the lake is balance.     Keywords: oxbow lake, rainy season, fish capture, diversity index

Abstract

The water surface of the dam of the Fisheries and Marine Science Faculty of Riau University is almost covered by Pistia stratiotes and this condition may affect the availability of fish in that area. To understand the types of fish associated with that aquatic plant, a research has been conducted February to March 2017. Based on plant density, there were 3 sampling sites, site 1 (46.19 plants/m2), site 2 (14.6 plants/m2) and site 3 (52.31 plants/m2). A modified quadrant (2 x 2 m, completed with fish trapping net attached) was placed for an hour in each site. Samplings were conducted 4 times, once/week. Results shown that there is a relationship between the plant density and the number of fish as well as the types of fish present. As the density of the plant increase, the number and type of fish present was also increase. The types of fish present are as follows: Trichogaster trichopterus, T. pectoralis, Trichopsis vittata, Rasbora einthovenii, Oreochromis nilloticus, Xenentodon canciloides, and Channa striata. In the lower surface of the plant, there were fish eggs attached. Data obtained indicate that there were 7 fish species associated with P. stratiotes and the community of the plant may serves as hatchery of the associated fish.Keywords : The Dam of the Fisheries and Marine Science Faculty of Riau University, Aasosoation
