Abstract:

Globally, suitable freshwater habitats are undergoing alterations and fish population declines, primarily attributed to the swift changes in climate and land use. Developing an effective conservation policy for freshwater fish necessitates careful consideration of the impacts of climatic and spatial factors. This study focuses on the analysis of 64 threatened freshwater fish in Bangladesh to anticipate their current and future climatically suitable habitats, utilizing the bioclim() species distribution model. Additionally, this study examines existing inland hydrographic networks and their cor

Abstract:

In South Africa, freshwater habitats are among the most threatened ecosystems, and freshwater fishes are the most threatened species group. Understanding patterns in freshwater fish diversity, threat, invasion, and protection status are vital for their management. However, few studies have undertaken such analyses at ecologically and politically appropriate spatial scales, largely because of limited access to comprehensive biodiversity data sets. Access to freshwater fish data for South Africa has recently improved through the advent of the Freshwater Biodiversity Information System (FBIS). We

Abstract:

Amphibians are more threatened than any other vertebrate class, yet evidence for many threats is missing. The Cape lowland fynbos (endemic scrub biome) is threatened by habitat loss, and natural temporary freshwater habitats are removed in favour of permanent impoundments. In this study, we determine amphibian assemblages across different freshwater habitat types with special attention to the presence of invasive fish. We find that anuran communities differ primarily by habitat type, with permanent water habitats having more widespread taxa, while temporary water bodies have more range restric

Abstract:

New Zealand’s freshwater ecosystems support a diverse and unique array of endemic flora and fauna. However, the conservation of its freshwater biodiversity is often overlooked in comparison to terrestrial and marine environments, and is under increasing threat from agricultural intensification, urbanisation, climate change, invasive species, and water abstraction. New Zealand has some of the highest levels of threatened freshwater species in the world with, for example, up to 74% of native freshwater fish listed as endangered or at risk. Threatened species are often discounted in water policy

Abstract:

Freshwater fish represent half of all fish species and are the most threatened vertebrate group. Given their considerable passion and knowledge, aquarium hobbyists can play a vital role in their conservation. CARES is made up of many organizations, whose purpose is to encourage aquarium hobbyists to devote tank space to the most endangered and overlooked freshwater fish to ensure their survival. We found the CARES priority list contains nearly six hundred species from twenty families and two dozen extinct-in-the-wild species. The major families were typically those with the largest hobbyist af

Abstract:

Freshwater ornamental fish diversity of Tamilnadu, India was recorded during January 2012 to December (14 species), Poecilidae and Osphronemidae (7 species), Cobitidae (6 species), Osteoglossidae (5 species), Callichthyidae and Mastacembelidae (3 species each), 2012. During the survey period, a total number of 122 ornamental fish species were identified belonging to 78 genera, 29 families and 10 orders. Cichlidae family represented maximum number of fish species (33 species) followed by the family Cyprinidae (21 species), Characidae Doradidae, Loricariidae and Pimelodidae (2 species each) and

Abstract:

The conservation Area (lubuk larangan) is one of the fish resource conservation areas. However, recently, the types of fish that live in this area have become increasingly threatened due to environmental changes and non-selective fishing. Therefore, it is important to study the diversity of freshwater fish in the conservation area (Lubuk Larangan) located along the Bangko River, Luak Kapau Village, South Solok Regency, West Sumatra Province, Indonesia. This data will be valuable in determining which fish species should be prioritized for domestication as potential candidates for fish cultivati

Abstract:

Freshwater ecosystems in Lithuania are threatened by the introduction of invasive fish species including Neogobius fluviatilis, N. melanostomus, Perccottus glenii, and Pseudorasbora parva. Data on helminth parasites of these fishes have not been comprehensively studied, with only two reports on parasites of N. melanostomus from the Curonian Lagoon and Baltic Sea, Lithuania. We examined 278 fish individuals representing 4 invasive species from 13 waterbodies. Using morphological and molecular analyses, we identified 29 helminth taxa representing 15 digenean trematodes, 6 nematodes, 4 cestodes,

Abstract:

Freshwater ecosystems in New Zealand have been under considerable and increasing stress since European colonisation. The draining of ninety per cent of wetlands and the removal of a similar amount of indigenous vegetation cover has placed much strain on the health of freshwater bodies. These changes wrought massive impacts through the loss of the crucial hydrologic and biological functions performed by intact wetland and forest ecosystems. These impacts have been exacerbated by the more recent intensification of farming, with the concomitant addition of excess nutrients and sediment to water a

Abstract:

Emergent infectious diseases have an increasing impact on both farmed animals and wildlife. The ability to screen for pathogens is critical for understanding host–pathogen dynamics and informing better management. Ranavirus is a pathogen of concern, associated with disease outbreaks worldwide, affecting a broad range of fish, amphibian, and reptile hosts, but research has been limited. The traditional screening of internal tissues, such as the liver, has been regarded as the most effective for detecting and quantifying Ranavirus. However, such methodology imposes several limitations from ethic

Abstract:

Background The use of ornamental fish as pets has important implications for the conservation of the species used in fish keeping, particularly in relation to overexploitation. Understanding ornamental fish keepers’ relationship with the hobby can provide important information for assessing the potential impacts of the activity. Here, we analyzed the profile of Brazilian ornamental fish keepers and evaluated their preferences and the implications of their choices. Methods Information was obtained by applying questionnaires to 906 ornamental fish keepers participating in fish keeping groups in

Abstract:

AbstractIn Europe 37% of freshwater fish are threatened. However, conservation activity is less widespread for fish compared to other vertebrate groups. The Vulnerable European mudminnow Umbra krameri is a marshland fish endemic to the Carpathian Basin. Its range and population have declined significantly since the 1990s. The main threats to the species are habitat loss and the invasive Chinese sleeper Perccottus glenii. During 2008–2012 a species conservation programme was established to rescue broodstocks from threatened populations, breed them under controlled conditions, translocate both r

Abstract:

The energetic status of freshwater fish provides a dynamic measure of their energy balance in response to the environment they occupy. Commercially available microwave technology (the ‘energy meter’) provides a rapid, non-lethal and inexpensive alternative to traditional laboratory methods for the determination of energy density. The energy meter requires species-specific confirmation of the water–lipid relationship, and comparison of energy meter readings with laboratory-determined estimates of the whole-body energy density. I explored the applicability of the energy meter to the threatened M

This study contributes preliminary data on the fish checklist of Sungai Rengai, Kuala Lipis, Pahang and the fish status reported by IUCN. Sungai Rengai is located southeast of Penjom Goldmine, Kuala Lipis. Specimens were collected using an electro-fisher aided with scoop nets and cast nets. Fish specimens were sorted, identified, measured, and released. Altogether, 48 individuals caught belonged to six families and nine species, with Cyprinidae as the dominant family and Osteochilus vittatus as the most abundant species (14 individuals).
