| Summary: | No abstracts are to be cited without prior reference to the author.Spatio-temporal dynamics related to sub-structuring of Atlantic cod stocks may affect how the populations in different management areas respond to recovery measures. Using data from mark recovery and electronic tag studies, we test the assumption that there is an exchange of cod between two adjacent cod management areas, one in the Irish Sea (ICES Division VIIa) and the other in the western English Channel and Celtic Sea (ICES Divisions VIIe-k). We evaluate 1522 archived and current mark recovery data (1960’s- present day) to assess the seasonal changes in distribution of cod within ICES Divisions VIIa and VIIe-g. In addition, we report on the results of a collaborative electronic data storage tagging (DST) programme of cod in the Irish and Celtic Sea, spanning the years 1999 to 2009. During this time, 693 DSTs have been deployed on cod between 43cm and 110cm, and 54 of the tags have been returned yielding over 2700 days of data. We used a ... |
