Variation in hatch date distributions, settlement and growth of juvenile plaice (L.) in Icelandic waters
No abstracts are to be cited without prior reference to the author. Hatch date distribution, larval phase and subsequent growth of juvenile plaice (Pleuronectes platessa L.) in different regions around Iceland were determined by otolith microstructure analysis.

No abstracts are to be cited without prior reference to the author.
