Harike wetland was declared a Ramsar site in 1990. It is located at the confluence of two major rivers of Indus rivers system, the Beas and the Sutlej, but was never explored extensively for its existing fish biodiversity. Earlier only 27 fish species of commercial value were reported from the wetland. Acknowledging its importance for rich diversity fish assemblages in seven different reaches o...

The structure of coral reef habitat has a pronounced influence on the diversity, composition and abundance of reef-associated fishes. However, the particular features of the habitat that are most critical are not always known. Coral habitats can vary in many characteristics, notably live coral cover, topographic complexity and coral diversity, but the relative effects of these habitat character...

Despite comprising only 2.2% of the area of the Northern Territory, estuaries are major repositories of biodiversity; 40% of all fishes recorded from the Northern Territory occur in estuaries and 33% of all northern Australian freshwater fishes require access to estuaries to breed. Estuaries are vital nursery areas for many fish species including many that are of economic importance. Importantl...

In this article, we focus on documented and possible effects of fish stocking in terms of ecosystem services. The increasing use of fish stocking between 1970 and 2000 in the semiurban setting of Stockholm archipelago, Sweden, is used as case study. The objective is to analyze this management practice from an ecosystem perspective, accounting for both the ecological and social context of releas...

The study of deep-sea fish fauna is hampered by a lack of data due to the difficulty and high cost incurred in its surveys and collections. Taiwan is situated along the edge of the Eurasia fig, at the junction of three Large Marine Ecosystems or Ecoregions of the East China Sea, South China Sea and the Philippines. As nearly two-thirds of its surrounding marine ecosystems are deep-sea environme...

Roads are responsible for various negative impacts on terrestrial and aquatic biodiversity. However, the effects of roads used by vehicles biodiversity have been little explored. In this study, based reports obtained from digital media technical reports, we provide an overview pollution in Brazilian ecosystems caused leakage trucks. We found 73 truck leaks that reached waterbodies, polluting th...

—Historically, the upper Willamette River valley in western Oregon was characterized by seasonal floods and large expansions of its stream network. During the past century, human activities have altered or eliminated many intermittent stream and floodplain habitats in the valley. As a result, the remaining intermittent streams and ditches, referred to as watercourses, may still provide habitat ...

Nujiang River (NR), an essential component of the biodiversity hotspot of the Mountains of Southwest China, possesses a characteristic fish fauna and contains endemic species. Although previous studies on fish diversity in the NR have primarily consisted of listings of the fish species observed during field collections, in our study, we DNA-barcoded 1139 specimens belonging to 46 morphologicall...

In this study, two new freshwater fish species, Gambusia holbrooki Girard, 1859 and Petroleuciscus borysthenicus (Kessler, 1859) were reported from Simenlik-Akgöl Lagoon in Yeşilırmak Basin (Samsun). Turkey has a rich biodiversity terms of fish. Because climate change, periodic ichthyofauna monitoring updating fauna are critical. holbrooki, Eastern mosquitofish, is an invasive species widesprea...
