Characteristics of Bangka Island which is an archipelago region with high economic potential of marine and fishery resources, it is deemed necessary to conduct research on the diversity of freshwater fish to support the increase of economic, ecological and conservation value of freshwater fish resources. Because of considering the research especially freshwater biodiversity of fish is seldom doing in Bangka Island, this research need to done. The aim of this research is to compile and identify the diversity of freshwater fish species in Bangka Island and to identify the potential utilization of freshwater fish species in Bangka Island based on the characteristics of dichromaticism and dimorphism. There are 63 species of 24 families of freshwater fish in the waters of Bangka Island. 2 unidentified fish species. Family Cyprinidae is the most caught type of 18 individuals. Fish potential analysis shows that there are 26 species of fish with potential for consumption, 33 species of fish have ornamental potential, 5 types of fish have ornamental potential and consumption, and 1 species of unidentified fish potential. Analysis of water quality in three observation streams indicates that water quality is still good for fish life

In order to update the IUCN Red List of all freshwater fish species inhabiting the Maghreb region, comprehensive knowledge of their respective geographic ranges is essential. Here we present site-scale distribution records derived from all known sources for native and alien freshwater fish species distributed in Morocco, Algeria and Tunisia. Corrected data compiled from the Global Biodiversity Information Facility plus author contributions and digitised literature data are presented as GIS maps, and the wider scientific and conservation communities are called upon to help fill knowledge gaps and maximise the value of this new database for a region in which freshwater biodiversity is undergoing a serious decline.

Abstract Distributional range of freshwater blenny Salaria fluviatilis extends to the tributaries along the Mediterranean and Black seas. It is considered endangered in several Mediterranean European countries. Although previously mentioned in the lists of freshwater fish species, its presence has never before been confirmed in Bosnia and Herzegovina. Consequently, this has led to doubts about its distribution there. A sample specimen of freshwater blenny was obtained from the lower Neretva River (Adriatic Sea watershed) in Bosnia and Herzegovina in May 2020, representing the first reliable record of this species. Considering that this record confirms older reports, however, it seems that earlier surveys have failed to locate the fish. Knowledge of the composition of fish species in river basins and updating their list are among the important requirements for managing the biodiversity of each country, as well as water and fish resources.

Fish Pass

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.
