Spatial Distribution of Numerical Density of Pelagic Juveniles (0‐Group) of Broadcast Spawning Fish Stocks Follows a Common Statistical Pattern

Fish and Fisheries, EarlyView.
ABSTRACT Statistical distributions of spatial abundance data of animal populations can be informative about underlying processes and mechanisms that govern the spatial distributions. Here, we examine a large data set from annual 0‐group fish surveys in the Barents Sea (1980–2017) collected with standardised trawl sampling from a regular grid with 30–35

Exploring indirect effects of a classic trophic cascade between urchins and kelp on zooplankton and whales

Scientific Reports
Kelp forest trophic cascades have been extensively researched, yet indirect effects to the zooplankton prey base and gray whales have not been explored. We investigate the correlative patterns of a trophic cascade between bull kelp and purple sea urchins

Estimating Time‐Varying Productivity and Reference Points: A Case of North Sea Demersal Fish Stocks

Fish and Fisheries, EarlyView.
ABSTRACT The productivity of marine fish populations determines both maximum sustainable yield (MSY) and resilience to exploitation. While biological reference points like MSY and BMSY$$ {B}_{\mathrm{MSY}} $$ depend on species traits and population density, they are also influenced by environmental variability and ecological interactions.

Increase in Harp Seal Ecosystem Role After the Cod Collapse in Newfoundland & Labrador

Fish and Fisheries, EarlyView.
ABSTRACT Pinniped populations have been increasing worldwide, posing challenges for fisheries management, including damage to fishing gear and competition for resources. In the Northwest Atlantic, harp seal numbers have increased from 1.8 million in 1970 to 6.5 million in 1990, stabilising at 4.4 million in 2024—one of the largest pinniped populations ...

Incorporating Climate Change Impacts Within Harvest Strategies: An Overview of Approaches

Fish and Fisheries, EarlyView.
ABSTRACT Ensuring that harvest strategies are robust to climate change is a top priority for many fisheries jurisdictions globally. This is because climate change is altering ecosystem structure and the productivity of marine species. We outline a range of approaches for incorporating climate change impacts within harvest strategies, including how a ...

Recurrence of the Spatial Structure of Summer Larval Fish Assemblages Linked to Hydrodynamics in the NW Mediterranean

Fisheries Oceanography, EarlyView.
ABSTRACT In this study, we aim to investigate the contribution of various sources of variability, environmental, spatial and interannual on the larval fish assemblages (LFA) in summer off the Catalan coast, an area with a wide array of environmental conditions.
