Variation in migration pattern, broodstock origin, and family productivity of coho salmon hatchery populations in British Columbia, Canada, derived from parentage‐based tagging

recommendations! Published in 2019 at "Ecology and Evolution"

DOI: 10.1002/ece3.5530

Abstract: Abstract In salmonid parentage‐based tagging (PBT) applications, entire hatchery broodstocks are genotyped, and subsequently, progeny can be nonlethally sampled and assigned back to their parents using parentage analysis, thus identifying their hatchery of origin and… read more here.

recommendations! Published in 2024 at "North American Journal of Fisheries Management"

DOI: 10.1002/nafm.10961

Abstract: Hatchery‐produced salmon and steelhead Oncorhynchus mykiss mitigate for habitat loss and support valuable commercial, recreational, and tribal fisheries. However, excessive interactions between hatchery and wild fish can also cause harm to wild populations. Weirs have… read more here.

DOI: 10.1002/nafm.11034

Abstract: We assessed the relative proportions of wild‐ and hatchery‐origin summer steelhead Oncorhynchus mykiss caught by sport anglers in the Deschutes River, Oregon. Our objective was to evaluate if steelhead of wild or hatchery origin were… read more here.

DOI: 10.1007/s10452-019-09733-0

Abstract: Fluctuating asymmetry is the non-directional deviations from bilateral symmetry and occurs across organisms. Fish otoliths are often used to test for differences in symmetry as otoliths aid in hearing, homing, and balance. Here, we evaluated… read more here.

DOI: 10.1007/s10641-019-00864-9

Abstract: This paper describes a study on the environmentally dependent brain size plasticity in hatchery-reared Atlantic salmon Salmo salar L. Using a factorial experimental design, we tested whether tank fish density, local hatchery standard (150 fish… read more here.

recommendations! Published in 2020 at "Environmental Biology of Fishes"

DOI: 10.1007/s10641-020-00968-7

Abstract: Hatchery production of Pacific salmon for release into the environment is a common tool for conservation and supplementation of depleted stocks. Hatchery conditions are controlled to support high survival rates; however, once released into the… read more here.

DOI: 10.1016/j.aqrep.2017.11.001

Abstract: Abstract The viability of rainbow trout Oncorhynchus mykiss (Walbaum, 1792) culture is being challenged progressively by global warming. Previous trials with Australian and Japanese rainbow trout lines suggested that improvements in thermal performance may be… read more here.

DOI: 10.1016/j.aquaculture.2020.735452

Abstract: Abstract Eastern oyster, Crassostrea virginica, aquaculture is a rapidly growing industry in the US. Although selective breeding programs have successfully developed lines of C. virginica with faster growth and improved disease resistance for aquaculture, maintaining… read more here.

DOI: 10.1016/j.lmot.2021.101732

Abstract: Abstract Climbing perch is a potamodromous fish that undertake lateral migration from the permanent water bodies to flooded areas during the rainy season and return to permanent water bodies at the end of flood. In… read more here.

DOI: 10.1051/alr/2024018

Abstract: Sub-Saharan Africa, including Ethiopia, is a center of native Nile tilapia populations, which are important for conservation and aquaculture development. Nile tilapia aquaculture in Ethiopia is dominated by small-scale fish farming in ponds, with seeds… read more here.

DOI: 10.1051/alr/2025016

Abstract: The European flat oyster, Ostrea edulis, once formed extensive reefs along European coasts. These reef ecosystems are now functionally extinct, but support for their restoration is rapidly growing. Efforts are currently limited by a bottleneck… read more here.
