Northern cod (Gadus morhua) movement: insights from acoustic telemetry and genomics

Journal of Fish Biology, EarlyView.
Abstract Knowledge of the timing and diversity of fish movements within a commercially exploited stock complex is required to ensure the sustainability of fisheries. Although migration can be driven by environmental factors, genomic mechanisms also play an important role in this complex life‐history trait. The northern cod (Gadus morhua) stock complex,

New cod war of words:'Cod is God' versus 'sod the cod'—Two opposed discourses on the North Sea Cod Recovery Programme [PDF]

, 2008
New insights into the North Sea Cod Recovery Programme (CRP), initiated in 2003 by the European Commission to reverse the long-term decline in cod stocks, are presented using discourse analysis.

Ossification of Atlantic cod ( Gadus morhua ) – Developmental stages revisited [PDF]

Aquaculture, 2017
Abstract In studies of marine larvae, it is common to use days post-hatch as a developmental reference point. We show that age is a poor measure of morphological and physiological development in Atlantic cod. Therefore, we propose a set of five developmental stages of Atlantic cod from start-feeding until the juvenile stage, based on cranial ...

Sequence capture analysis determines spatial and temporal stock contributions to a mixed coastal anadromous fishery

Journal of Fish Biology, EarlyView.
Abstract Employing a citizen science model of partnerships with recreational and commercial fishers, we collected 5298 fin‐clip samples of striped bass Morone saxatilis over a 2‐year period and a broad geographic area that encompassed a majority of the species migratory range.

Haemoglobin revisited: delineating population structure with the world’s first molecular genetic marker used in fisheries research

Royal Society Open Science
When haemoglobin genotyping was implemented in the early 1960s to investigate population genetic structure in Atlantic cod (Gadus morhua), it became one of the first molecular genetic markers deployed in fisheries research worldwide.

A note on stomach contents of minke whales (Balaenoptera acutorostrata) in Icelandic waters

NAMMCO Scientific Publications, 2000
There is limited available information on food habits of minke whales (Balaenoptera acutorostrata) in coastal Iceland. Sixty-eight minke whales were examined for stomach contents; 51.5% contained fish only, 22.1 % krill (Euphausiacea) only, 25.0% fish ...

Baltic cod reproduction in the Gotland Basin: annual variability and possible causes [PDF]

, 1999
Baltic cod spawning takes place in the deep basins and reproduction success is mainly related to environmental conditions (salinity and oxygen regimes, i.e. the 'reproduction volume'). Due to the Baltic Sea heterogeneity, cod reproduction success in the

Polar cod Boreogadus saida occurrence is driven by temperature at the margin of its distribution

Journal of Fish Biology, EarlyView.
Abstract With a warming Arctic, suitable habitat for polar cod Boreogadus saida (Lepechin 1774) is predicted to decrease. We investigated the changes in distribution of polar cod on the southern limit of its distribution in the Atlantic Ocean (around Iceland) during both autumn and spring after a recent period of warming in the area.

Heavy metals in Southern Baltic fish: present situation and future trends [PDF]

Acta Ichthyologica et Piscatoria, 1991
Herring (Clupea harengus) and cod (Gadus morhua) from three Southern Baltic areas were studied. Mercury content was determined with CV AAS and assays of the remaining metals were carried out with flame AAS.

Individual variability in activity patterns in Atlantic halibut (Hippoglossus hippoglossus) revealed using pop‐up satellite tags

Journal of Fish Biology, EarlyView.
Abstract Understanding fish behaviour and activity patterns is essential for interpreting their ecology and the processes that shape population dynamics, yet such information remains limited for wild fishes because observing individuals in situ is challenging.
