Age readings of Sebastes marinus otoliths: bias and precision between readers and otolith preparation methods
(ICES CM documents, Working paper, 2001)This study presents a comparative age reading on Sebastes marinus from the Icelandic shelf within an otolith exchange program between institutes in Germany, Iceland and Norway. Out of a series of 212 otolith pairs, ... -
Bomb dating and age determination of large pelagic sharks

Length structure of deep-pelagic fishes sheds new light to their life histories
(ICES CM documents;2008/C:14, Working paper, 2008)Here we use a new technique to study life history variation in deep-pelagic fishes from a midocean ridge system. Shape of length distribution in a population is to a significant extent determined by the degree to which ... -
