| Abstract: | The journey of the European eel to the spawning area in the Sargasso Sea is still a mystery. Several trials have been carried
out to follow migrating eels with pop-up satellite tags (PSATs), without much success. As eels are very efficient swimmers,
tags likely interfere with their high swimming efficiency. Here we report a more than twofold increase in swimming cost caused
by a regular small satellite tag. The impact was determined at a range of swimming speeds with and without tag in a 2-m swimming
tunnel. These results help to explain why the previous use of PSATs to identify spawning sites in the Sargasso Sea was thus
far unsuccessful. |
