Do Habitat Restoration Efforts and the Associated Releases of Hatchery‐Reared Fish Affect the Genetic Diversity and Integrity of Native Brown Trout Populations?

Fisheries Management and Ecology, EarlyView.
ABSTRACT Habitat restoration may protect brown trout (Salmo trutta) populations from loss of genetic diversity by increasing environmental carrying capacity and, consequently, population size. However, the accompanying release of hatchery‐reared fish may threaten the genetic integrity of native populations through introgression.

Fine‐Scale Factors Affecting the Abundance and Thermal Sensitivity of Nonnative Brook Trout in Coldwater Rocky Mountain Streams

Fisheries Management and Ecology, EarlyView.
ABSTRACT The Brook Trout (Salvelinus fontinalis) is a globally distributed nonnative species that threatens native salmonids in coldwater streams. Understanding the factors regulating Brook Trout densities in coldwater refugia is critical to effective management, so we investigated (a) fine‐scale drivers of Brook Trout abundance and (b) factors ...

Capture Probability and Effects of Bait Type on Learning Behavior in an Unexploited Population of Northern Pike (Esox lucius)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Changes in angling response were studied over a period of three years in a natural, previously unfished population of northern pike. Standardized angling sessions took place during two weeks in spring and autumn with three bait types: bright‐ and natural‐colored soft plastic baits and a dead baitfish.

11-Deoxycorticosterone (DOC)’s Action on the Gill Osmoregulation of Juvenile Rainbow Trout (Oncorhynchus mykiss)

Biology
In aquaculture, stress can negatively affect fish growth. For years, the cortisol hormone has been thought to play both glucocorticoid and mineralocorticoid functions. Nevertheless, recent research has suggested that 11-deoxycorticosterone (DOC) released

An Updated Ecology of Atlantic Salmon (Salmo salar) at Sea

Fisheries Oceanography, EarlyView.
ABSTRACT Atlantic salmon have had a key role in European and North American oceans and human societies. Salmon are exploited and observed in rivers and along coasts, but there has always been great interest in knowing where salmon are going when they are at sea.

Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems

Fisheries Oceanography, EarlyView.
ABSTRACT Understanding the structure of pelagic food webs across multiple trophic levels is critical for elucidating species interactions, energy flow, and anthropogenic impacts on production. This study presents a comprehensive analysis of the eastern North Pacific pelagic food webs, focusing on the Gulf of Alaska (GoA) during late winter of 2019.

Genetic diversity, admixture, and hatchery influence in Brook Trout (Salvelinus fontinalis) throughout western New York State

Ecology and Evolution, 2019
Although Brook Trout are distributed across most of eastern North America, population numbers have declined in many regions due to habitat loss, climate change, and competition with non‐native species.
