Genes, fish and fisheries: translating science into policy

Journal of Fish Biology, EarlyView.
Abstract The 2024 Annual Symposium of the Fisheries Society of the British Isles reviewed the burgeoning impact of ‘omics’ technologies on fish ecology, management and forecasting. As with life sciences more generally, major advances in speed, cost‐effectiveness and breadth of applications in ‘omics’ has had profound societal and environmental impacts.

Chemistry and shape of anadromous Alosine otoliths show extent of spawning population intermixed in a shallow wind-dominated estuary

Frontiers in Marine Science, 2015
The Alewife Alosa pseudoharengus and Blueback Herring A. aestivalis are highly migratory coastal species of the NW Atlantic, and species of concern due to continued low abundance.

Return migration to fresh water and overwintering locations used by sympatric anadromous populations of Arctic char (Salvelinus alpinus) and Dolly Varden (Salvelinus malma malma)

Journal of Fish Biology, EarlyView.
Abstract Anadromous Arctic char (Salvelinus alpinus) and northern form Dolly Varden (Salvelinus malma malma) are highly valued by Indigenous communities in northern Canada. Rapid, ongoing environmental changes are affecting populations of both of these iteroparous species, and understanding variability in life‐history tactics is essential for ...

Shortjaw kokopu (Galaxias postvectis Clarke) distribution, habitat selection and seasonal activity in the northern Tararua Ranges : a thesis presented in partial fulfillment of the requirements for the degree of a Masters of Science in Ecology at Massey University, Palmerston North, New Zealand [PDF]

, 2002
Freshwater fish communities were surveyed at 59 sites in the Mangatainoka, Makakahi and Ruamahanga catchments of the northeastern Tararua Ranges during 2000/01.

Sulfur isotopes in otoliths allow discrimination of anadromous and non-anadromous ecotypes of sockeye salmon (Oncorhynchus nerka) [PDF]

, 2010
Oncorhynchus nerka occur both as anadromous sockeye salmon that spend most of their life in the ocean, and as non-anadromous kokanee salmon that remain in fresh water their entire lives.

Brackish-water residency and semi-anadromy in Arctic lake trout (Salvelinus namaycush) inferred from otolith microchemistry [PDF]

Journal of Great Lakes Research, 2016
Abstract Lake trout, Salvelinus namaycush , are considered a freshwater species but have been documented using brackish and marine water environments in the Arctic in a semi-anadromous manner. The objective of this study was to describe lake trout life histories present in the brackish waters of Husky Lakes, Northwest Territories (NT) using otolith ...

Contrasting population genomic structuring of northern pike (Esox lucius L.) in fresh‐ and brackish water environments: Implications for management and conservation

Journal of Fish Biology, EarlyView.
Abstract Understanding the factors that shape population genetic structure is crucial for advancing evolutionary studies and developing effective management and conservation strategies. The northern pike (Esox lucius L.) is a top teleost predator that inhabits fresh and brackish water environments in the northern hemisphere.

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

Landscape, demographic, and dispersal parameters influence the spread and establishment of an aquatic biological invasion

Ecosphere
Human‐mediated species introductions are contributing to the biotic homogenization of global flora and fauna. Despite extensive research, we lack simple methods of predicting how and where an introduced species will spread and establish, particularly in ...

Predation on Atlantic herring (Clupea harengus ) eggs by the resident predator community in coastal transitional waters [PDF]

, 2017
Atlantic herring (Clupea harengus) migrates from offshore to coastal areas to spawn and their eggs and larvae may substantially increase prey resources for resident predators.
