Patterns of subphotic fish assemblages on seamounts in the Northwestern Hawaiian Islands were identified and compared for potential structuring influences, including the bottom-up effects of regional oceanic productivity and top-down predation pressure exerted by visiting monk seals (Monachus schauinslandi). Patterns in fish size, density, and biomass were evaluated at the deep extreme (350–500...

15 The influence of sea-cage aquaculture on wildfish assemblages has received little attention 16 outside of Europe. Sea-cage aquaculture of finfish is a major focus in South Australia, and 17 while the main species farmed is southern bluefin tuna (Thunnus maccoyii), there is also an 18 important yellowtail kingfish (Seriola lalandi) industry. Yellowtail kingfish aquaculture did 19 not appear t...

Understanding recolonization processes of intertidal fish assemblages is integral for predicting the consequences of significant natural or anthropogenic impacts on the intertidal zone. Recolonization of experimentally defaunated intertidal rockpools by fishes at Bass Point, New South Wales (NSW), Australia, was assessed quantitatively by using one long-term and two short-term studies. Rockpool...

Networks of no-take marine reserves and partially-protected areas (with limited fishing) are being increasingly promoted as a means of conserving biodiversity. We examined changes in fish assemblages across a network of marine reserves and two different types of partially-protected areas within a marine park over the first 5 years of its establishment. We used Baited Remote Underwater Video (BR...

Low-head dams in arid regions restrict fish movement and create novel habitats that have complex effects on fish assemblages. The influence of low-head dams and artificial wetlands on fishes in Muddy Creek, a tributary of the Colorado River system in the USA was examined. Upstream, fish assemblages were dominated by native species including two species of conservation concern, bluehead sucker, ...

Abstract Spatiotemporal variation in fish assemblage structure was conducted from January to December 2015 in order to know the impacts of sanctuary on ichthyo-faunal diversity with its indices and major hydrological factors from six sampling stations of Karatoya fish sanctuary sectioned in the river Karatoya. A total of 69 fish species was obtained from this sanctuary including 21 threatened ...

An adult swordfish (Xiphias gladius L.) was reported for the first time at coastal Mediterranean fish-farm facilities. This record highlights the necessity to assess the potential ecological changes to wild fish assemblages caused by coastal farming activity, especially to this type of endangered large migratory fish predator, which could be taken into account in future management strategies.

Spatiotemporal variations in fish assemblage structure was studied from January to December 2015 in order to understand the impacts of the sanctuary on ichthyo-faunal diversity and to determine the indices and major hydrological factors in six sampling stations of Karatoya Fish Sanctuary sectioned in the River Karatoya. A total of 69 fish species were obtained from this sanctuary including 21 t...

Distributions of mobile animals have been shown to be heavily influenced by habitat and climate. We address the historical and contemporary context of fish habitats within a major zootone: the Recherche Archipelago, southern western Australia. Baited remote underwater video systems were set in nine habitat types within three regions to determine the species diversity and relative abundance of b...

Nonwadeable rivers are unique ecosystems that support high levels of aquatic biodiversity, yet they have been greatly altered by human activities. Although riverine fish assemblages have been studied in the past, we still have an incomplete understanding of how fish assemblages respond to both natural and anthropogenic influences in large rivers. The purpose of this study was to evaluate associ...
