Identifying escaped farmed salmon from fish scales using deep learning [PDF]

Biology Methods and Protocols
Abstract Escaped farmed salmon are a major concern for wild Atlantic salmon (Salmo salar) stocks in Norway. Fish scale analysis is a well-established method for distinguishing farmed from wild fish, but the process is labor and time intensive.

Genetic divergence of farmed Atlantic halibut (Hippoglossus hippoglossus) and potential for impact on wild populations [PDF]

BMC Research Notes
Objective Domestication of fish for aquaculture involves the production of strains that differ genetically from their wild counterparts. This is a concern when commercial production occurs in installations from which individuals can escape into the wild ...

Genetic analyses verify sexually mature escaped farmed Atlantic cod and farmed cod eggs in the natural environment [PDF]

Evolutionary Applications
Elucidating the effects of domesticated organisms escaping into the natural environment represents a topic of importance in both evolutionary and conservation biology.

Domesticating the wild through escapees of two iconic mediterranean farmed fish species [PDF]

Scientific Reports
Extractive fisheries and marine aquaculture share space and target species. Several regional-scale examples exist of escapees entering wild fisheries landings, yet no study has assessed the influence of aquaculture on landings at an ecosystem scale.

Genetic investigation of the large-scale escape of a tropical fish, barramundi Lates calcarifer, from a sea-cage facility in northern Australia

Aquaculture Environment Interactions, 2014
Expansion of sea-cage aquaculture has increased incidences of large-scale escapes of farmed fish. Whilst escape events are relatively well-characterised for temperate fish species, such as salmonids, there are no studies that report the occurrence and ...

Use of fatty acid profiles to monitor the escape history of farmed Atlantic salmon

Aquaculture Environment Interactions, 2015
Farmed Atlantic salmon can escape from fish farms at various stages of their life, from juveniles to large mature fish. Escapees that enter rivers to spawn pose a threat to the genetic integrity of wild populations.

Meagre escapees: consequences of a local-absent farmed species in the W-Mediterranean

Frontiers in Marine Science, 2015
Meagre (Argyrosomus regius Asso, 1810) is a large sciaenid considered an emerging species in the European aquaculture, especially for W-Mediterranean countries.

Winning the invasion roulette: escapes from fish farms increase admixture and facilitate establishment of non‐native rainbow trout [PDF]

Evolutionary Applications, 2011
AbstractAquaculture is a major source of invasive aquatic species, despite the fact that cultured organisms often have low genetic diversity and tend to be maladapted to survive in the wild. Yet, to what extent aquaculture escapees become established by means of high propagule pressure and multiple origins is not clear.

Piscine orthoreovirus sequences in escaped farmed Atlantic salmon in Washington and British Columbia

Virology Journal, 2019
Background Piscine orthoreovirus (PRV) is an emergent virus in salmon aquaculture belonging to the family Reoviridae. PRV is associated with a growing list of pathological conditions including heart and skeletal inflammation (HSMI) of farmed Atlantic ...

Three decades of farmed escapees in the wild: a spatio-temporal analysis of Atlantic salmon population genetic structure throughout Norway. [PDF]

PLoS ONE, 2012
Each year, hundreds of thousands of domesticated farmed Atlantic salmon escape into the wild. In Norway, which is the world's largest commercial producer, many native Atlantic salmon populations have experienced large numbers of escapees on the spawning ...
