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.

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

Abstract ADONIS:CE was used to design a computer model for the management of Sabanejewia aurata (De Filippi, 1863) populations in the Natura 2000 site of Sighişoara-Târnava Mare (ROSCI0227). The recommended management model is based on the environmental needs of the species, inventoried according to the local habitats, as well as the indicators of conservation status and relevant management measures, and takes into account human pressures and threats identified in the research area. Such computer models were established for all protected fish species found at the site ROSCI0227.

Non-indigenous fish species (NIFS) can cause severe ecological impacts on the invaded ecosystems and are considered as one of the leading factors of freshwater biodiversity loss. Unraveling the spatial overlap between NIFS and critically endangered (CR) fish species can contribute to targeted conservation actions to minimize the potential negative effects. In this study, we applied geostatistical analyses to investigate the spatial overlap of NIFS against fish species that are designated under the CR status according to the IUCN and the Hellenic Zoological Society (HZS) Red Lists. Distributional data (presence–absence) from 800 records of 52 NIFS were compiled for both lentic and lotic ecosystems of Greece. Our results indicate that freshwater ecosystems under high NIFS richness were located mainly in lowland areas and often near large cities and ecosystems with well-developed commercial and recreational fisheries. On the contrary, low NIFS richness was observed in mountainous regions and in relatively small river basins. Overlapping areas of CR species with moderate to high NIFS richness (1.5–4.3 NIFS per 1 km2) were relatively high (~50%). A quarter of the overlapping areas (24.8%) fall within NATURA 2000 network, where legal management bodies could implement specialized programs to minimize the negative impacts. However, the majority of CR fish species’ distribution remains in unprotected areas indicating that protected areas should be re-designed to include areas containing freshwater species under the highest threatened category. Our findings demonstrate that whole assemblages of fishes are rapidly changing as NIFS spread into Greece and many freshwater ecosystems of outstanding biodiversity conservation value are under significant invasion pressure.
