Parathelphusa pardus is a new freshwater crab species found in the swamp area in the Sawah Village. A study purpose to understand the type of food consumed by the crabs has been conducted in October-November 2016. Crab stomach was removed and its content was analyzed by using a microscope. Type of food present was identified and noted and the Index of Preponderance was calculated. The crabs were captured using a traditional fishing line and traps. Results shown that the stomach of P. pardus contains detritus (64,87%), phytoplankton (28,60%), crustacean remains (5,88%), and algae (0,49%). In each molting status, as well as in male and female crab, the food composition of P. pardus is not different. These crabs may accelerates the degradation of litter particles in the swamp, provide feces as natural food for other small organisms and improve the soil oxygenation through their burrows.Keywords : Parathelphusa pardus, stomach content analyis, Index of Preponderance

Watas Hutan Lake is one of the oxbow lakes in the Kampar regency. This lake is overgrown by various types of water plants that almost cover the surface of the lake. This condition hamper the fishing activities in the lake. This research aims to discover the types and density of the aquatic plant in the lake and it was conducted from February to March 2015. Field sampling was done 2 times, a month period. The plants were then identified based on Van Steenis (1981).Result shown that there were 7 species of aquatic plants present and they are belonged to 4 classes, 7 families. They are Eichhornia crassipes, Pandanus sp., Colocasia sp., Cyperus sp., Ipomoea aquatica, Paspalum sp., and Salvinia natans. The most common plant Salvinia natans (37.6-56 organisms/m2, relative density 22.4-43.1 %), while the rarest was Ipomoea aquatica (3.3-27 organisms/m2, relative density 2.5-14.1 %).

There are many types of aquatic plant and fish in the Parit Belanda River, but there is no information on the assosiation of aquatic plant and fish in the river. To understand that assosiation, a research has been conducted in February – March 2016. Sampling were conducted once /week for a month period. Poecilia reticulata, Trichopsis vittata, Aplocheilus pancha and Oreochromis niloticus were found around the community of Paspalum sp. Around the Eichhornia crassipes community, there were T. vittata, Rasbora einthovenii, P. reticulata, Trichogaster trichopterus, and Esomus metallicus present. While T. trichopterus, R. einthovenii, E. metallicus, Oxygaster anomarula, P. reticulata, and T. vittata were found around the Ipomoea aquatica community. There is similarity in fish species present around different aquatic plants. Based on data obtained, it can be concluded that there is no specific association between aquatic plant and fish species in the Parit Belanda River.Keywords: Aquatic plant, fish, assosiation, Parit Belanda River

The upstream the Umban Sari River was inhabit by numerous fish species. Information on these fish, however, is almost none. To understand the biodiversity of fish in that river, a study has been conducted from September to October 2015. The fish was sampled using several net types (mesh size 0.1 – 1.0 inch), electrofishing and scoop net. Data were then analyzed to find the relative profusion (Kr), fish occurrence frequency and the presence fish (Fi). The fish sampled were identified based on Kottelat (2013). Results shown that there were 15 species (8 families) present. There were Osteochilus hasselti, Parachela oxygastroides, Cyclocheilichthyes apogon, Esomus metallicus, Rasbora cephalotaenia, Rasbora trilineata, Clarias batrachus, Oreochromis niloticus, Channa striata , Trichogaster trichopterus, Trichogaster pectoralis, Trichopsis vittata, Pterygoplichthys pardalis , Xenentodon canciloides and Monopterus albus. The most common fish was Esomus metallicus. Trichogaster trichopterus and Channa striata were distributed evenly along the river, as they were found in each sampling area (Fi 100%). Besides the endemic fishes, there were 5 exotic species (Fi 37%) present, namely E. metallicus, O. niloticus, T. pectoralis, C. striata and P. pardalis.Keyword: fish biodiversity, Umban Sari River, Pekanbaru, Riau

Dam in the Fisheries and Marine Science Faculty Riau University is inhabited by many types of aquatic organism, included mollusk. To understand the types of freshwater mollusk present in the dam, a study was conducted in May to June 2016. Samplings were done for three days. There were two sampling stations namely Station 1 (in the dam) and Station 2 (in the dam’s outlet). Mollusks were captured directly by hand or they were picked up from sediment sampled using shovel. The mollusks were then photographed and identified Results shown that there were2 classes, 3 ordos, 6 families, 6 genus, and 7 species. They were Lymnaea persica, Gyraulus sp, Bellamyasp, Pilaglobosa, Thiara (Sernjyla) riqueti, Melanoides prashadi, and Elliptio producta. The value of water qualityparameters measured were temperature 28 oC, transperancy 42.5 cm, depth 20-150 cm, pH 5, dissolved oxygen 3.27-8.26 mg/L and free carbondioxide 7.1-11.9 mg/L.Keywords : Freshwater Mollusk, Dam, Pila sp, Bellamnya sp, Gyraulus sp
