TLDR
In this article, a review of the current understanding of factors controlling salmonid populations in streams and how this contributes to better fisheries management is presented, with an emphasis on understanding the uncertainties and risks inherent in modelling wild populations.About:

Journal ArticleDOI
Habitat requirements of Atlantic salmon and brown trout in rivers and streams
TL;DR: It is prudent to accept that although manipulations of habitat may appear to be beneficial when considered locally, they should be measured and assessed where possible in terms of the production of returning adults and/or high quality smolts.
Journal ArticleDOI
A review of the likely effects of climate change on anadromous Atlantic salmon Salmo salar and brown trout Salmo trutta, with particular reference to water temperature and flow.
Bror Jonsson,Nina Jonsson +1 more
TL;DR: There is reason to expect a northward movement of the thermal niche of anadromous salmonids with decreased production and population extinction in the southern part of the distribution areas, migrations earlier in the season, later spawning, younger age at smolting and sexual maturity and increased disease susceptibility and mortality.
Journal ArticleDOI
Consequences of climatic change for water temperature and brown trout populations in Alpine rivers and streams
TL;DR: In this paper, the authors employed a quantitatively defined reference optimum temperature range for brown trout, based on the sinusoidal regression of seasonally varying field data, and found that brown trout catch data documenting an altitudinally dependent decline indicate that climate-related population decrease has in fact occurred.
Journal ArticleDOI
A critical life stage of the Atlantic salmon Salmo salar: behaviour and survival during the smolt and initial post-smolt migration.
Eva B. Thorstad,Frederick G. Whoriskey,Ingebrigt Uglem,A. Moore,Audun H. Rikardsen,Bengt Finstad +5 more
TL;DR: In this paper, the authors synthesize and review the environmental factors affecting the migration behavior and survival of smolts and post-smolts during the river, estuarine and early marine phases, and how behavioral patterns are linked to survival.

Cultured Atlantic salmon in nature: a review of their ecology and interaction with wild fish
Bror Jonsson,Nina Jonsson +1 more
TL;DR: Experimental evidence has revealed that cultured parr's greater aggression often allows them to dominate wild parr, although smaller cultured parR can be subordinated if they co-occur in fast-flowing water and if wild smolts have established prior residence.

The evolution of life histories
TL;DR: In this article, age and size at maturity at maturity number and size of offspring Reproductive lifespan and ageing are discussed. But the authors focus on the effects of age and stage structure on fertility.
Book
On the Dynamics of Exploited Fish Populations
TL;DR: Pitcher and Pauly as mentioned in this paper used a simple theory of fishing, illustrated by analysis of a trawl factoy, to give the annual yield in weight from a fishery in a steady state.
Journal ArticleDOI
Stock and Recruitment
TL;DR: Plotting net reproduction (reproductive potential of the adults obtained) against the density of stock which produced them, for a number of fish and invertebrate populations, gives a domed curve whose apex lies above the line representing replacement reproduction.

Quantitative fisheries stock assessment
Ray Hilborn,Carl J. Walters +1 more
TL;DR: Quantitative fisheries stock assessment as mentioned in this paper, Quantitative fishery stock assessment: Quantitative fishes stock assessment, Quantitative fish stock assessment and stock assessment in the field of fishery management.
Book
Quantitative ecology and the brown trout
TL;DR: The brown trout is a successful polytypic species and natural selection and genetic differences between brown trout populations are examined, as well as mechanisms responsible for population regulation in young brown trout.
