A century of tagging experiments on 174 Atlantic cod (Gadus morhua) groups is reviewed
and the frequency and spatial distribution of four migratory behaviours documented. Of all …

Electromagnetic surveys generate electromagnetic fields to map petroleum deposits under
the seabed with unknown consequences for marine animals. The electric and magnetic …

Climatic change has been implicated as the cause of abundance fluctuations in marine fish
populations worldwide, but the effects on whole communities are poorly understood. We …

The migrations of cod (> 37 cm) in the Skagerrak and Kattegat were investigated in an
archival tagging programme conducted between 2003 and 2006. Cod tagged at different …

The codfish family includes more than 500 species that vary greatly in their abundance in
areas like the North Sea and are widely fished. Gadoids (codfish) gather at particular …

Rebuilding the Gulf of Maine stock of Atlantic cod (Gadus morhua) has been much slower
than expected. An important source of scientific uncertainty contributing to the difficulties in …

We examined the spatial dynamics of Atlantic cod, Gadus morhua, through its life history on
the northeast and southeast coasts of Newfoundland in order to delineate dispersal and …

The occurrence of natal homing in marine fish remains a fundamental question in fish
ecology as its unequivocal demonstration requires tracking of individuals from fertilization to …

During the course of the last century, populations of Atlantic cod Gadus morhua L. have
undergone dramatic declines in abundance across their biogeographic range, leading to …

The sites where haddock spawn and the factors that bring the fish together to spawn at
particular locations are not well known. We have located haddock in the sea by listening for …
