Invasive bighead carp Hypophthalmichthys nobilis have spread throughout the Mississippi River basin, negatively impacting ecosystems. We used a remnant population (32 years after stocking) to better understand H. nobilis . We observed high annual survival (>95%), but growth was relatively slow. Lapilli otolith sections were reliable aging structures but underestimated H. nobilis age by ~10%. Dorsal‐fin rays and postcleithra al...

Accurate information on population structure is essential for effective fisheries management. Greenland halibut ( Reinhardtius hippoglossoides ) in the North Atlantic is managed as four separate offshore stocks. We use Multivariate Autoregressive State‐Space (MARSS) models to assess population structure by means of abundance and biomass trends in four regions (Norwegian Sea, Iceland, Southeast Greenland, and Northwest Atlantic...

Characterizing the extent of genetic differentiation among individuals and its distribution across the genome is increasingly important to inform both conservation and management of exploited species. The Greenland Halibut is one of the main demersal fish species to be commercially exploited in Eastern Canada, and accurate information on geographic population structure and local adaptation is required to ensure the long-term p...

Greenland shark Somniosus microcephalus is a potentially important yet poorly studied cold‐water species inhabiting the North Atlantic and Arctic Oceans. Broad‐scale changes in the Arctic ecosystem as a consequence of climate change have led to increased attention on trophic dynamics and the role of potential apex predators such as S. microcephalus in the structure of Arctic marine food webs. Although Nordic and Inuit populati...
