A global synthesis of peer‐reviewed research on the effects of hatchery salmonids on wild salmonids

JR McMillan, B Morrison, N Chambers… - Fisheries …, 2023 - Wiley Online Library
Hatcheries have long produced salmonids for fisheries and mitigation, though their
widespread use is increasingly controversial because of potential impacts to wild salmonids …

Density‐dependent effects on salmonid populations: A review

GD Grossman, TN Simon - Ecology of Freshwater Fish, 2020 - Wiley Online Library
We reviewed 199 published data sets (21 species) to assess the relative frequency of
various density‐dependent processes in salmonids. We examined studies for the presence …

The effect of intra-and interspecific competition on coexistence in multispecies communities

G Barabás, M J. Michalska-Smith… - The American …, 2016 - journals.uchicago.edu
For two competing species, intraspecific competition must exceed interspecific competition
for coexistence. To generalize this well-known criterion to multiple competing species, one …

Infection status of masu salmon Oncorhynchus masou by the parasite Salmonema cf. ephemeridarum (Nematoda, Cystidicolidae)

Y Ogura, K Hasegawa - Journal of Fish Biology, 2024 - Wiley Online Library
Nematodes that parasitize salmonids are found in both seawater and freshwater. Unlike
seawater species such as those in family Anisakidae, freshwater species have not been well …

Temperature‐dependent competition between juvenile salmonids in small streams

J Watz, Y Otsuki, K Nagatsuka, K Hasegawa… - Freshwater …, 2019 - Wiley Online Library
Biotic interactions affect species distributions, and environmental factors that influence these
interactions can play a key role when range shifts in response to environmental change are …

A delayed effect of the aquatic parasite Margaritifera laevis on the growth of the salmonid host fish Oncorhynchus masou masou

K Ooue, A Terui, H Urabe, F Nakamura - Limnology, 2017 - Springer
Parasitic species often have detrimental effects on host growth and survival. The larvae of
the genus Margaritifera (Bivalvia), called glochidia, are specialist parasites of salmonid …

The density dependent interspecific competition between nonnative salmonids, rainbow trout and brown trout

K Hasegawa - Environmental Biology of Fishes, 2016 - Springer
Interspecific interactions play a key role in determining species assemblages when
nonnative species are introduced. In the Chitose River system, Hokkaido, northern Japan …

Wild masu salmon is outcompeted by hatchery masu salmon, a native invader, rather than brown trout, a nonnative invader

K Hasegawa, A Nakashima - Biological Invasions, 2018 - Springer
Artificially grown native species are released into natural environments to increase
biological resources or to recover threatened populations. Such stocks typically have …

Are hatchery chum salmon fry a native invader? Direct and indirect effects of stocking salmon fry on stream organisms

K Hasegawa, T Ohta, S Takahashi - Hydrobiologia, 2018 - Springer
Native species may show invasiveness toward a recipient ecosystem through increases in
abundance as a result of artificial stocking events. Salmonid species are typical examples of …

The strength of density dependence on body size of young‐of‐the‐year masu salmon, Oncorhynchus masou, varies over ontogeny in Horokashubuto stream …

K Hasegawa, J Okado, G Sahashi… - … of Freshwater Fish, 2024 - Wiley Online Library
The relationships between body size and density of salmonids in natural streams have been
well studied, and density‐dependent growth (somatic growth) is interpreted as the principal …
