Cod with satellite tag eaten by a whale contributes to science

Sperm whale diving behaviour recorded in the N-Atlantic following predation on Atlantic cod tagged with pop-up satellite tag 

Cod with satellite tag eaten by whale www.laxfiskar.is

In a study on Atlantic cod using pop-up satellite tags (PSATs), carried out by Johannes Sturlaugsson and colleagues at the research company Laxfiskar (Cod PSAT Research Project), one of the cod was eaten by whale. That gave remarkable insight into such event but moreover changed the study on that cod behaviour ecology into study of whale behaviour. The cod had carried the PSAT for nearly 5 months and was at 300m depth in cold sea (2.1¬įC) in Icelandic waters when eaten by the whale as shown in figure.

Atlantic cod (Gadus Morhua) tagged with pop-up satellite tags (PSATs) 

- Introduction of the study and first results

Pop-up_2012_Iceland_Cod_Project-Copyright_Laxfiskar.is-17

At the end of April 2012 the research company Laxfiskar in Iceland started pioneering research on migration and behaviour of Atlantic Cod, when 8 cod were tagged with pop-up satellite tags. Tagged cod were big spawning fish, ranging from 105 to 136 cm in length. Tagging site was spawning ground in Bay Faxafloi off SW-Iceland.

This study is the first one to use pop-up satellite tags to study Atlantic cod migrations.
