Determination of interannual variability in early life history of Pleuronectes platessa (L.) using otolith microstructure
Plaice, Pleuronectes platessa, is a commercially exploited flatfish species in northern European waters. Despite numerous studies on plaice early life history, information for its northern range of distribution is still scarce. Here we present data on juvenile plaice from a cold-water estuary in nor...

Plaice, Pleuronectes platessa, is a commercially exploited flatfish species in northern European waters. Despite numerous studies on plaice early life history, information for its northern range of distribution is still scarce. Here we present data on juvenile plaice from a cold-water estuary in northern Norway. Otolith microstructure can be used to understand recruitment processes namely their interannual variability which is assumed to be generated in the early life stage. Therefore, the main objectives of this study were to examine differences in age, time of hatching and settlement, larval duration, and growth rates among years and to relate observed patterns with seawater temperature. Plaice 0-group juveniles were sampled from an inshore nursery ground (Valosen, Bodø, Norway) between 2005 and 2006, and otolith microstructure was examined.
