Key gaps remain in the definition and application of keystone species concepts for fisheries management: A systematic scoping review

People and Nature, Volume 8, Issue 3, Page 582-597, March 2026.
Abstract A keystone species is one whose influence is disproportionate to its abundance, the absence of which would change the dynamics of an ecological or human community. Despite its widespread use in the scientific literature, there is a limited understanding of how the keystone concept is defined or measured, or applied in practice, and especially ...

The lake cod Gadus morhua kildinensis in the context of conservation biology

Water Biology and Security
Atlantic cod, Gadus morhua, is a marine fish, but there are several Arctic lakes, where it also occurs. Mogilnoye Lake on Kildin Island in the Barents Sea is especially famous for them. It is a salinity stratified meromictic lake.

Early life exploration behaviour and life‐history loci are colocalized in an adaptive genomic hotspot in Atlantic salmon

Journal of Animal Ecology, Volume 95, Issue 3, Page 418-429, March 2026.
The genetic architecture of phenotypic correlations offers insights into how natural selection operates in the wild. Two functional phenotypes in Atlantic salmon, early life exploration and age‐at‐maturity, are correlated at an adaptive genomic hotspot, but through distinct genetic markers (SNPs), ruling out causality.

Density dependence modulates climate change impacts on eastern Bering Sea snow crab

Journal of Applied Ecology, Volume 63, Issue 3, March 2026.
Our results underscore the need for management capable of addressing the impacts of both density and climate effects on multiple processes in harvested populations. Non‐stationarity in drivers of population dynamics (e.g. climate change) will further affect the ability of management to achieve sustainable yields.

Effects of fishing during the spawning period: implications for management [PDF]

Avoidance of fishing during the spawning season has been proposed as a contribution to achieving sustainable exploitation. Here we review the biological effects of fishing during the spawning period and explore their implication on sustainable management.

Genetisk analyse av merket torsk (Gadus morhua)

, 1981
Detailed genetic analysis have provided valuable information about the population structure of several commercially important fish species. The investigations have mainly concentrated on the problem on stock identification, and recently to the concervation of genetic resources.

Genetics in the Ocean's Twilight Zone: Population Structure of the Silvery Lightfish Across Its Distribution Range

Evolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT The large estimates of mesopelagic fish biomass have long fuelled harvesting interests in the relatively untouched twilight zone of the ocean. The silvery lightfish—one of the most abundant species inhabiting the North Atlantic mesopelagic layer—is a candidate for such a fishery despite its enormous ecological importance and the insufficient ...

Century‐Scale Changes in the Feeding Patterns of Demersal Fish Species in the Western North Sea

Fish and Fisheries, Volume 27, Issue 2, Page 99-115, March 2026.
ABSTRACT Understanding the extent and magnitude of change in marine food webs requires historical data that predates modern monitoring efforts. Such information can provide invaluable insights into the longer‐term impacts of altered trophic interactions, yet it is rarely incorporated into marine policy frameworks.

Body Condition as a Shared Response to Environment in a Commercially Important Demersal Fish Assemblage

Fish and Fisheries, Volume 27, Issue 2, Page 264-284, March 2026.
ABSTRACT Measures of an organism's weight at a given length are often considered reliable indicators of energy reserves or ‘condition’, which can be related to fecundity and risk of mortality. Understanding the impact of environmental change on fish condition may therefore inform sustainable management of human activities in marine ecosystems.
