Exotic invaders gain foraging benefits by shoaling with native fish [PDF]

Royal Society Open Science, 2014
Freshwater habitats are under increasing threat due to invasions of exotic fish. These invasions typically begin with the introduction of small numbers of individuals unfamiliar with the new habitat. One way in which the invaders might overcome this disadvantage is by associating with native taxa occupying a similar ecological niche.

Long-term fish monitoring underlines a rising tide of temperature tolerant, rheophilic, benthivore and generalist exotics, irrespective of hydrological conditions

Journal of Limnology, 2018
The invasion of exotic species is one of the main threats to worldwide biodiversity and can be aided by changes in environmental conditions. We hypothesized that a temporal trend of decreasing discharge and increasing temperature might have favored the ...

Exotic fish culture in pond aquaculture system: Study of Rupchanda (Piaractus brachypomus) culture in Assam, India

Cogent Business & Management, 2023
Exotic fish species are introduced in the pond culture system with a view to improving aquaculture development. Apart from aquaculture development, the introduction of exotic species has an undesirable impact on the natural biodiversity due to prolific ...

Protecting endemic species from African Catfish invasion when community behavioral responses get in the way.

PLoS ONE, 2018
Exotic invasive fish species, when introduced into pristine natural environments, threaten the survival of many endemic species. Management challenges associated with controlling their further spread and protecting endemic species can be exacerbated when

Exotic fish and decreasing habitats vis-à-vis conservation of freshwater fish biodiversity of Bangladesh

Journal of Fisheries, 2022
Multiple stressors including biological invasion have long been recognised in conservation of freshwater fish biodiversity. Works in this line have, however, been still scanty in Asia and South America – the continents known for rich biodiversity.

Fishing Grounds and the Invasive Species Impact: a Case Study in a Coastal Brazilian Watershed [PDF]

Brazilian Archives of Biology and Technology
one of the leading causes of global biodiversity loss is the introduction of non-native species with high potential for invasion, and fish farms are largely responsible for introducing these species into continental aquatic ecosystems.

Prioritization of fish communities with a view to conservation and restoration on a large scale European basin, the Loire (France) [PDF]

, 2008
The hierarchical organization of important sites for the conservation or the restoration of fish communities is a great challenge for managers, especially because of financial or time constraints.
