Aerobic scope is sustained through a heatwave in juvenile Atlantic salmon (Salmo salar)

Journal of Fish Biology, EarlyView.
Abstract Aquatic ectotherms are vulnerable to heatwave‐induced physiological stress, which arises from increased energy demands and reduced dissolved oxygen content in warmer waters. Understanding thermal physiology is critical for predicting how commercially and ecologically important populations could be affected by the increasing risk of rising ...

Fin development in stream- and hatchery-reared Atlantic salmon

Aquaculture, 2003
To determine the effect of development and environment on fin growth, we measured fin lengths of juvenile Atlantic salmon (Salmo salar) from two hatcheries (August, October and April–May), stream-reared fish (July and October) stocked as fry into two tributaries, and smolts from the main stem of the Connecticut River (May).

State salmon hatchery, ca. 1910

, 1910
In 1899, the state of Washington opened a salmon hatchery on Soos Creek, east of Auburn. In the hatchery's pools, Department of Fisheries workers hatched salmon eggs and raised young salmon for release in area streams.

Rapid increase in abundance and distribution of invasive pink salmon (Oncorhynchus gorbuscha) within a diverse, large Barents Sea catchment

Journal of Fish Biology, EarlyView.
Abstract Pink salmon originate from the North Pacific area but were introduced into northwest Russia from the late 1950s onwards. Since 2017, the alien species has increased dramatically in abundance and rapidly invaded adjacent areas of the North Atlantic region.

The marine life of Atlantic salmon: evidence from the chemistry of scales [PDF]

, 2010
This research provides a new method to identify likely marine feeding grounds for migratory pelagic species that are problematic to directly study at sea.

Atlantic salmon of wild and hatchery origin have different migration patterns

, 2022
Hatcheries are frequently used to support or restore threatened Atlantic salmon populations. However, little is known about how rearing affects behaviour and fitness of hatchery adults that return to the river to spawn.

Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebrates

Journal of Fish Biology, EarlyView.
Abstract The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O.

Hatchery tank enrichment affects cortisol levels and shelter-seeking in Atlantic salmon (Salmo salar)

, 2013
Stocking programs using hatchery-reared salmon are often implemented for augmenting natural populations. However, survival of these fish is often low compared with wild conspecifics, possibly because of genetic, physiological, and behavioural ...

Histological characterisation of gonadal sex differentiation in Malabar red snapper (Lutjanus malabaricus) for aquaculture advancement

Journal of Fish Biology, EarlyView.
Abstract The Malabar red snapper (Lutjanus malabaricus) is a high‐value tropical marine species receiving growing attention for aquaculture development in Singapore and Southeast Asia. At present, seed production relies primarily on uncontrolled mass spawning in sea cages, a practice that lacks consistency, biosecurity and control of genetic ...

Estimate of hatchery and natural-origin salmon.

, 2013
Proportion of adult Chinook salmon (Oncorhynchus tshawytscha) spawning in-river on the Mokelumne River (USA) or within the entire Mokelumne River watershed (river+hatchery) assigned to hatchery or natural origins based on δ34S values in otoliths. Laplace
