A framework for the use of conservation hatcheries to support wild Pacific salmon recovery in Canada
FACETSHatcheries have long been used to produce Pacific salmon (Oncorhynchus spp.), and in recent years, they have been used to assist the recovery of populations that have declined and become imperiled.

Ploidy effects on hatchery survival, deformities, and performance in Atlantic salmon (Salmo salar)
, 2011 The production of sterile triploid Atlantic salmon (Salmo salar) may help address the increasing pressure on the industry to reduce potential breeding between farmed escapees and wild fish populations.

Occurrence of Kabatana takedai (Microspora) in Juvenile Masu Salmon (Oncorhynchus masou) reared at Varying Water Temperatures in a Hatchery [PDF]
, 2001 Infections with the microsporidian parasite Kabatana takedai (Awakura, 1974) were monitored for juvenile masu salmon (Oncorhynchus masou) held at various water temperatures controlled using river and spring waters in the Chitose Hatchery, Hokkaido, Japan.

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Recent salmon declines: a result of lost feeding opportunities due to bad timing? [PDF]
PLoS ONE, 2010 As the timing of spring productivity blooms in near-shore areas advances due to warming trends in global climate, the selection pressures on out-migrating salmon smolts are shifting.

Salmon fry predation by seabirds near an Alaskan hatchery [PDF]
Marine Ecology Progress Series, 1997 We es t~mated the mortality of hatchery-raised pink Oncorhynchus gorbuscha and chum 0 keta salmon fry from seabird predation near a salmon hatchery In Lake Bay, Prince William Sound, Alaska, USA. Fleld counts of seabirds and observations of feeding rates for plunge-diving seabirds were obtained durlng salmon fry releases between Apnl and June 1995 ...

River Research and Applications, EarlyView.ABSTRACT Pacific salmon face substantial challenges when migrating through anthropogenically modified river systems, such as the Sacramento‐San Joaquin River Delta (the Delta). Non‐physical behavioral barriers, such as the bioacoustic fish fence (BAFF), are one potential solution for guiding fish away from hazards without obstructing water flow ...

Aquatic Living Resources, 2021 Parentage assignment with genomic markers provides an opportunity to monitor salmon restocking programs. Most of the time, it is used to study the fate of hatchery-born fish in those programs, as well as the genetic impacts of restocking.
