Salmon hatchery strays can demographically boost wild populations at the cost of diversity: quantitative genetic modelling of Alaska pink salmon [PDF]

Royal Society Open Science
Hatcheries are vital to many salmon fisheries, with inherent risks and rewards. While hatcheries can increase the returns of adult fish, the demographic and evolutionary consequences for natural populations interacting with hatchery fish on spawning ...

Social influences complement environmental cues to stimulate migrating juvenile salmon [PDF]

Movement Ecology
Background The large-scale seasonal migrations undertaken by many species require complex navigational and timing decisions. Animals migrating in groups might benefit from collective decision making, especially if the environment has large local ...

Reduced relative fitness in hatchery‐origin Pink Salmon in two streams in Prince William Sound, Alaska

Evolutionary Applications, 2022
Previous studies generally report that hatchery‐origin Pacific Salmon (Oncorhynchus spp.) have lower relative reproductive success (RRS) than their natural‐origin counterparts. We estimated the RRS of Pink Salmon (O.

Reproductive success in wild and hatchery male coho salmon [PDF]

Royal Society Open Science, 2015
Salmon produced by hatcheries have lower fitness in the wild than naturally produced salmon, but the factors underlying this difference remain an active area of research.

Hatcheries to High Seas: Climate Change Connections to Salmon Marine Survival [PDF]

Ecology and Evolution
We investigated variations in the marine survival of Japanese hatchery chum salmon (Oncorhynchus keta) during 25 years of climate change (1998–2023).

Does density influence relative growth performance of farm, wild and F1 hybrid Atlantic salmon in semi-natural and hatchery common garden conditions? [PDF]

Royal Society Open Science, 2016
The conditions encountered by Atlantic salmon, Salmo salar L., in aquaculture are markedly different from the natural environment. Typically, farmed salmon experience much higher densities than wild individuals, and may therefore have adapted to living ...

Genetic versus rearing-environment effects on phenotype: hatchery and natural rearing effects on hatchery- and wild-born coho salmon. [PDF]

PLoS ONE, 2010
With the current trends in climate and fisheries, well-designed mitigative strategies for conserving fish stocks may become increasingly necessary.

Density‐dependent marine survival of hatchery‐origin Chinook salmon may be associated with pink salmon

Ecosphere, 2020
Understanding how protected species influence the population dynamics of each other is an essential part of ecosystem‐based management. Chinook salmon (Oncorhynchus tshawytscha) are critical prey for endangered southern resident killer whales (SRKWs ...

Details of artificial reproduction of Atlantic salmon (Semga) at the Umba fish hatchery [PDF]

BIO Web of Conferences, 2022
The world's demand for fish products for food and industrial purposes has already significantly exceeded the reproduction capacity of wild fish. Further increasing exploitation of natural fish populations leads to a sharp reduction in their numbers and ...

Potential factors affecting survival differ by run-timing and location: linear mixed-effects models of Pacific salmonids (Oncorhynchus spp.) in the Klamath River, California. [PDF]

PLoS ONE, 2014
Understanding factors influencing survival of Pacific salmonids (Oncorhynchus spp.) is essential to species conservation, because drivers of mortality can vary over multiple spatial and temporal scales.
