Climate change is rapidly modifying marine fish assemblages in the Arctic. As fish eggs and larvae have a narrower thermal tolerance than nonreproductive adults, their response to increasing temperatures is likely one of the main drivers of these changes.

MicroRNAs (miRNAs) are epigenetic markers with a key role in post-transcriptional gene regulation. Several studies have described the dysregulation of miRNAs in temperature and hypoxic stress responses of marine organisms, but their role in the response ...

Size class segregation of Arctic cod (Boreogadus saida) in a shallow High Arctic embayment
Arctic cod (Boreogadus saida (Lepechin, 1774)) vertically segregate by size class in deep waters, but such dynamics had not been explored in shallow waters.

Arctic cod (Boreogadus saida) (Lepechin, 1774) is often found in front of glaciers, which is the least studied of the species’ habitats. Uummannap Kangerlua and Sullorsuaq in West Greenland provide a unique opportunity to study Arctic cod in the glacial ...

Boreogadus saida (Lepechin, 1774). Arctic Cod or Polar Cod. To 46 cm (18.1 in) TL (Wienerroither et al. 2011), usually less than 25 cm (9.8 in) (Cohen in Cohen et al. 1990). The largest we know of from our area is a specimen from the Chukchi Sea measuring 30 cm (12 in) TL (Alverson and Wilimovsky 1966). Circumpolar in Arctic (Cohen in Cohen et al. 1990)

Summer foraging behaviour of shallow-diving seabirds and distribution of their prey, Arctic cod (Boreogadus saida), in the Canadian Arctic [PDF]
Productive areas in the Canadian Arctic seasonally provide top predators with accessible and often predictable sources of energy. Arctic cod (Boreogadus saida) aggregate in shallow bays during the summer and are exploited by seabirds and marine mammals ...

Arctic cod (Boreogadus saida) hatching in the Hudson Bay system [PDF]
Buoyant Arctic cod (Boreogadus saida) eggs are found at the surface or at the ice-water interface in winter. While winter temperatures in saline waters fall below 0°C, the temperature in areas affected by under-ice river plumes is slightly higher. Under-ice river plumes may therefore provide thermal refuges favoring the survival of the vulnerable early

Can vertical separation of species in trawls be utilized to reduce bycatch in shrimp fisheries?
Several shrimp trawl fisheries use a Nordmöre sorting grid to avoid bycatch of fish. However, small fish can pass through the grid. Therefore, the retention of juvenile fish often remains an issue during shrimp trawling.

Combined effects of crude oil exposure and warming on eggs and larvae of an arctic forage fish
Climate change, along with environmental pollution, can act synergistically on an organism to amplify adverse effects of exposure. The Arctic is undergoing profound climatic change and an increase in human activity, resulting in a heightened risk of ...
