| Summary: | No abstracts are to be cited without prior reference to the author.Process-based understanding of changes in commercial fish spatial distributions, and to disentangle the role of natural drivers and various anthropogenic impacts, is a challenging research topic with high relevance to resource management. Especially in time of locally high recruitment, it is important to understand beforehand how the local recruitment is translated to stock recovery over the whole assessment area. In case of Baltic cod, there has been an increase in abundance in one of the Baltic basin (ICES Sub-division 25), resulting in density-dependent decrease of weight at length (Svedäng 2014). However, the specimen did apparently not migrate eastwards out of the basin in search for better feeding conditions. ... |
