Knowledge and Management of Aquatic Ecosystems, 1990 Introduite en Amérique du Nord en 1883, la truite brune (Salmo trutta) a été ensemencée pour la première fois au Québec en 1890. Ce n'est cependant qu'au début des années 1950 qu'elle a commencé à susciter l'intérêt des aménagistes et des pêcheurs ...

Genetic Diversity and Hybridisation between Native and Introduced Salmonidae Fishes in a Swedish Alpine Lake. [PDF]
PLoS ONE, 2016 Understanding the processes underlying diversification can aid in formulating appropriate conservation management plans that help maintain the evolutionary potential of taxa, particularly under human-induced activities and climate change.

Errors in Length-weight Parameters at FishBase.org [PDF]
, 2011 Background: FishBase.org is an on-line database of fish related data that has been cited over 1500 times in the fisheries literature. Length-weight relationships in fish traditionally employ the model, W(L) = aL^b^, where L is length and W is weight ...

The genetic architecture underlying the evolution of a rare piscivorous life history form in brown trout after secondary contact and strong introgression [PDF]
, 2018 Identifying the genetic basis underlying phenotypic divergence and reproductive isolation is a longstanding problem in evolutionary biology. Genetic signals of adaptation and reproductive isolation are often confounded by a wide range of factors, such as

Using structured decision making to evaluate the tradeoffs of selective fish passage
Conservation Science and Practice, EarlyView.Abstract Dams have dramatically altered rivers and are a major contributor to native fish population declines. However, many dams serve important ecological, social, and economic functions, such as flood control, invasive species control, and provision of recreational opportunities.

Specific and individual differences in motility between salmonid spermatozoa [PDF]
Acta Ichthyologica et Piscatoria, 1973 Spermatozoan motility was examined in Salmo trutta L., Salmo trutta m. lacustris L., Salmo gairdneri Rich. and Salvelinus fontinalis (Mitch.) from different spawning grounds and fish cultures.

Fisheries Management and Ecology, EarlyView.ABSTRACT Stocking fish is a common practice in fisheries management, particularly for species of high conservation value or economic importance. Despite its widespread use, systematic evaluation of fish stockings remains scarce. This includes non‐native species such as rainbow trout (Oncorhynchus mykiss), which are intensively stocked into European ...

Drawn to the Sea: Charles Bradford Hudson (1865-1939), Artist, Author, Army Officer, with Special Notice of His Work for the United States Fish Commission and Bureau of Fisheries [PDF]
, 2009 The biography of Charles Bradford Hudson that follows this preface had its seeds about 1965 when I (VGS) was casually examining the extensive files of original illustrations of fishes stored in the Division of Fishes, National Museum of Natural History ...

Fisheries Management and Ecology, EarlyView.ABSTRACT Local ecological knowledge can be useful to assess data‐limited fisheries such as the Ontario Black Bass (Micropterus spp.) recreational fishery. We surveyed local anglers using the Life History Calendar approach to determine if there were perceived changes in fishing quality for Black Bass in eastern Ontario across different time periods. For

Conflict between background matching and social signalling in a colour-changing freshwater fish [PDF]
, 2016 The ability to change coloration allows animals to modify their patterning to suit a specific function. Many freshwater fishes, for example, can appear cryptic by altering the dispersion of melanin pigment in the skin to match the visual background ...
