Cleaner fish escape salmon farms and hybridize with local wrasse populations [PDF]

Royal Society Open Science, 2018
The genetic impact of farmed fish escaping aquaculture is a highly debated issue. However, non-target species, such as cleaner fish used to remove sea lice from farmed fish, are rarely considered.

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

Biol Methods Protoc
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 ...

Causal analysis of escape of Atlantic salmon and rainbow trout from Norwegian fish farms during 2010–2018

Aquaculture, 2021
Abstract Farmed fish escaping into the wild and other environmental concerns have curbed the expansion of the Norwegian aquaculture industry. Detailed knowledge of both direct and underlying causes of previous escape episodes is crucial to ensure successful development of new technology and targeted safety-measures at fish farms.

Mediterranean Aquaculture and Genetic Pollution: A Review Combined with Data from a Fish Farm Evaluating the Ecological Risks of Finfish Escapes

Journal of Marine Science and Engineering, 2023
Mediterranean finfish aquaculture is mainly represented by the production of the gilthead sea bream (Sparus aurata) and sea bass (Dicentrarchus labrax) growing in marine cage farms.

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.

Salmon on the lam: Drivers of escaped farmed fish abundance in rivers [PDF]

Journal of Applied Ecology, 2020
Abstract The production of Atlantic salmon in aquaculture has grown substantially over the last 40 years. The unintentional release of domesticated salmon poses a significant risk to the long‐term persistence of wild Atlantic salmon populations through ecological interactions and genetic introgression.

Wild and farmed burbot Lota lota: differences in energy consumption and behavior during the spawning season

Aquaculture Environment Interactions, 2021
Farmed fish released in a native environment can display different spawning behaviour compared to their wild conspecifics. In our study, farmed and wild burbot, a species recently introduced for aquacultural production, were equipped with electromyogram (

Phenotypic Convergence in Sea Bass (Dicentrarchus labrax) Escaping From Fish Farms: The Onset of Feralization? [PDF]

Frontiers in Marine Science, 2021
The impact of fish escaping from fish farms may depend on the extent to which escapees adapt to the natural environment, resemble wild conspecifics, and become feral. Yet, little is known about the process of feralization in marine fish. We examined phenotypic changes in body shape, body condition, and scale growth profiles of sea bass escaping from ...
