Abundance of native fishes, wild‐introduced salmonids and escaped farmed rainbow trout in a Patagonian reservoir

Lakes & Reservoirs: Science, Policy and Management for Sustainable Use, 2014
AbstractThe introduction of salmonids in Patagonia has resulted in significant impacts on its lakes, as well as a major impact on streams, in which native fishes seem to have been displaced almost completely by rainbow trout (Oncorhynchus mykiss). Another perspective is that the introduced salmonid species have resulted in wild fish populations that ...

Impacts of wild fishes attracted to open-cage salmonid farms in Norway

Aquaculture Environment Interactions, 2014
Salmonid farming affects both the environment and other industries, with impacts of wild fish attracted to fish farms being a major concern. Here, we summarized existing knowledge on the impacts of such aggregations around open-cage salmonid farms in ...

Risks to stocks of native trout of the genus Salmo (Actinopterygii: Salmoniformes: Salmonidae) of Serbia and management for their recovery [PDF]

Acta Ichthyologica et Piscatoria, 2015
Background. Insufficiently controlled stocking compromises the high diversity of wild trout stocks of Serbia. Native brown trout, Salmo cf. trutta Linnaeus, 1758, and Macedonian trout, Salmo macedonicus (Karaman, 1924), reveal remarkable diversity ...

Genetic analysis of Atlantic salmon captured in a netting station reveals multiple escapement events from commercial fish farms [PDF]

Fisheries Management and Ecology, 2012
AbstractMicrosatellite DNA analysis and statistical assignment methods were implemented to identify the origin of 190 farmed escaped Atlantic salmon recaptured over a period of 2 months at a netting station located in Trondheim fjord, Norway. Samples were also collected from farms within the region. The escapees originated from a minimum of two sources,

A pan-European valuation of the extent, causes and cost of escape events from sea cage fish farming

Aquaculture, 2015
AbstractAs part of an EU funded 7th Framework project, Prevent Escape, a programme of research was undertaken to document the extent, size and knowledge of the causes of escapes from marine fin fish farms in Europe over a three year period. Escape incidents were identified and assessed through questionnaires across the 6 countries (Ireland, UK, Norway,

Siblingship tests connect two seemingly independent farmed Atlantic salmon escape events

Aquaculture Environment Interactions, 2016
Aquaculture escapees represent a threat to the genetic integrity of native populations, may spread infectious agents and display ecological interactions with wild fish.

The reliability of AI consulting on the ecological impacts of the escape of farmed fish

Frontiers in Marine Science
Numerous studies have investigated the ecological impacts of escaped aquaculture fish. Whether people can objectively obtain this information through large language model (LLM) artificial intelligence (AI) systems, which are currently gaining increased ...

Using purposeful inbreeding to reduce outbreeding depression caused by escaped farmed Atlantic cod

Aquaculture Environment Interactions, 2013
Fish often escape from aquaculture operations, raising concerns of interactions with wild individuals. Farmed fish from genetically diverse populations grown outside their native range create the threat of outbreeding depression if they escape and ...

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

Biological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Rapid dispersion of escaped meagre (Argyrosomus regius ) from a coastal Mediterranean fish farm

Aquaculture Research, 2016
Meagre (Argyrosomus regius) is an emerging species in aquaculture considered a locally absent species in the Western Mediterranean. Little is known about meagre escape incidents from farms. To evaluate escape impacts and develop mitigation measures, knowledge about the behaviour of escaped meagre is necessary.
