AbstractAlthough small benthic freshwater fish species are an important biological component of fish assemblages and free instream movement is indispensable for their survival, they are often neglected in fish pass performance studies. In this study, a capture-mark-recapture approach was used to assess whether small bottom-dwelling species, including gudgeon (Gobio gobio), stone loach (Barbatula barbatula), spined loach (Cobitis taenia) and bullhead (Cottus gobio), were able to cross a pool-and-weir fish pass in a regulated lowland river. Some tagged individuals of stone loach (18%), gudgeon (7%) and spined loach (2%) managed to successfully ascend the fish pass under study, despite the fact that water velocity levels in the different overflows of the facility (between 0.55-1.22 m/s) exceeded the critical swimming speed of all three species. Although this suggests that a pool-and-weir fish pass is a able to facilitate upstream movement of some small benthic species in a regulated river, more detailed research incorporating advanced tagging and retrieving techniques is necessary.

The condition of Embaloh River is still well maintained, with clear water and a large variety of fishes. This is because the forest around Embaloh River is still dense; there is no deforestation, mining, and palm oil garden. In such a condition, the river is capable of maintaining a large variety of fishes that have not listed yet. Therefore, this research has the purpose of studying the variety of fishes in Embaloh River, and also to categorize the fishes based on their benefits, whether as decorative fishes, to be eaten, or even as a decorative fish and also to be eaten. The research was conducted on the Embaloh River, Banua Ujung Village, Embaloh Hulu District, Kapuas Hulu Regency. Research Data is obtained by the use of fishing equipment such as mesh, Bubu, Sauk, trawler, burst, and Talom. The method of research using the survey method, the selection of observation stations conducted with (purposive sampling) based on consideration of environmental conditions of the water. This location is made 3 (three) stations on the Embaloh River and 1 (one) station is on the lake (oxbow) called Lake Loane. Lake Loane is a stream of the Embaloh River Moreover, fish of species taken from Embaloh River and Loane Lake, which water from Embaloh River flows to, consist of several families of fish; Cobitidae (1 species), Cyprinidae (13 species), Elopidae (1 species), Grynocheilidae (1 species), Helostomatidae (1 species), Osphronemidae (2 species), Polynemidae (1 species), Pristolepididae (1 species), Sisoridae (1 species), and Syngnathidae (1 species).Keywords: Banua Ujung Village, Embaloh River, Fish Species Diversity, Loane Lake.

Individuals that occupy restricted home ranges for long periods have little chance to sample surrounding habitats and may only be able to respond to changes in the distribution of resources at very local scales. Processes leading to the selection of a home range, therefore, potentially have an important bearing on individual fitness and, ultimately, on population structure. In this study, movements associated with the establishment of home ranges by golden perch (Macquaria ambigua) and common carp (Cyprinus carpio) in an Australian lowland river were examined using radiotelemetry. To examine behaviour associated with exploration and settlement into new home ranges, fish were artificially translocated into an unfamiliar river section. Although there was substantial intraspecific variation in patterns of movement, all fish tracked over the entire study period eventually settled into restricted home ranges. Several fish of both species either moved away from established home ranges and settled in new areas, or undertook large-scale movements and subsequently returned to the original home range. It is suggested that such movements may provide a mechanism by which fish can reap the benefits of home-range occupation whilst still being able to respond to changes in the distributions of spatially and temporally dynamic resources.

Kepari village has two main rivers, namely Kepari River which is still surrounded by natural forests and Emperas River in which there is a former site of unauthorized gold mining. This research aims to collect data of the diversity of freshwater fish species in Kepari River and Emperas River, Kepari Village, Sungai Laur Sub-District, Ketapang Regency. Sampling point was carried out by making a sampling station that was placed by purposive sampling for the starting point and placed in the next station systematically. This researh was conducted at 2 (two) different locations and regions, namely Kepari River and Emperas River. Both locations were made 3 (three) stations or observation points, each with observation station length of 50 meters and interval per distance between stations of 200 meters. Each station was repeated 3 (three) times. Research results indicate that 60 species of fish caught in Kepari River and Emperas River are classified in 17 families. The highest number of species is 25 species of Cyprinidae family. Kepari River has 46 species of freshwater fish while Emperas River has 23 species of freshwater fish. The species that dominate Kepari River are Cyclocheilichthys apogon (Buing) and Osteochilus vittatus (Parau) while in Emperas River, the species are Trichogaster trichopterus (Empotar), Belontia hasselti (Kekopar) and Cyclocheilichthys apogon (Buing).Keywords: Diversity, Emperas River, Fish, Kepari River
