Disentangling the Drivers of a Piscivorous Intra‐Annual Cohort and the Contributions of Three Cohorts to Early‐Year Class Strength in Pikeperch (Sander lucioperca)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.

Capelin Size, Condition, and Abundance Through Multiple Heatwaves in Alaska

Fisheries Oceanography, EarlyView.
ABSTRACT Capelin (Mallotus spp.) are pelagic forage fishes that can be especially abundant in sub‐arctic marine ecosystems and are important prey for upper trophic‐level consumers. Abundance and distribution of capelin have been linked to ocean temperature, but the magnitude and directionality of thermal sensitivity can vary regionally.

Joint Spatiotemporal Models for the Estimation of Prey Consumption and Predator–Prey Overlap: Dynamics of Pacific Cod Predation on Snow and Tanner Crab in the Eastern Bering Sea

Fisheries Oceanography, EarlyView.
ABSTRACT Pacific cod (Gadus macrocephalus) are important predators of juvenile snow (Chionoecetes opilio) and Tanner crab (Chionoecetes bairdi) in the eastern Bering Sea (EBS), yet the relationship between cod–crab spatial overlap and total crab consumption is only partially understood.

Use of remotely-derived bathymetry for modelling biomass in marine environments [PDF]

, 2013
The paper presents results on the influence of geometric attributes of satellite-derived raster bathymetric data, namely the General Bathymetric Charts of the Oceans, on spatial statistical modelling of marine biomass. In the initial experiment, both the

Food intake of early juvenile western Baltic cod (Gadus morhua) during settlement transition

Journal of Fish Biology, EarlyView.
Abstract This study examines the gut contents of 203 early juvenile Atlantic cod [17–101 mm ± 18.48 mm standard deviation (SD)] from the Western Baltic Sea (ICES Subdivision 22) collected between 2020 and 2022. According to the observed prey (proportion of pelagic, intermediate and benthic items) in the cod guts, settlement transition from a pelagic to

Exploratory bottom trawling in Lake Victoria

, 1969
When the Lake Victoria Fisheries Research Project began, the background information necessary for the successful application of quantitative stock assessment was lacking. For this. reason and also due to the size of Lake Victoria, the complexity and variety of its many habitats, and its multispecies fishery, it was decided that initial stock assessment
