An Updated Ecology of Atlantic Salmon (Salmo salar) at Sea

Fisheries Oceanography, EarlyView.
ABSTRACT Atlantic salmon have had a key role in European and North American oceans and human societies. Salmon are exploited and observed in rivers and along coasts, but there has always been great interest in knowing where salmon are going when they are at sea.

Salmon lice dispersion in a northern Norwegian fjord system and the impact of vertical movements

Aquaculture Environment Interactions, 2016
The abundance and distribution of salmon lice Lepeophtheirus salmons originating from fish farms in a northern Norwegian fjord during the summer of 2010 was investigated by means of a numerical model, underpinned by field observations.

A longitudinal study of avian pox in a small passerine, the Dunnock (Prunella modularis)

Ibis, EarlyView.
Long‐term, longitudinal studies of disease in wild bird populations are rare. Diseases are important determinants of bird survival and may spill‐over into other species including livestock and, in some cases, humans. Avian pox is a globally distributed disease, resulting from infection by viruses in the genus Avipoxvirus (APV).

Beyond the specimen: rethinking ornithological collecting in a changing world

Ibis, EarlyView.
Natural history collections underpin a wide range of ornithological research, yet the context in which they operate is rapidly changing. Advances in genomics, digitization and analytical approaches are transforming what can be learned from specimens, while accelerating environmental change is increasing the need for temporally explicit, integrative ...

Do the biological characteristics of trout (Salmo trutta) smolts influence their spring migration timing and maiden marine sojourn duration?

Journal of Fish Biology, EarlyView.
Abstract Anadromous salmonids migrate seaward to exploit feeding and growth opportunities in marine habitats, yet how smolt biological characteristics influence their marine migratory behavior remains poorly understood. This study used 9 years of trout (Salmo trutta) population monitoring data from 15,595 tagged age‐0+ parr, 1033 smolts detected ...

Atlantic salmon (Salmo salar) aquaculture in a changing climate: Quantitative insights from industry records and climate projections

Journal of Fish Biology, EarlyView.
Abstract Predicting and understanding the implications of climate change on Atlantic salmon (Salmo salar) aquaculture is a fundamental step to understanding risk and mitigating potential impacts. Here, we statistically downscale established climate models using satellite‐based sea surface temperature data and in situ industry measurements to inform ...
