ABSTRACT: Hyperpigmentation is a term describing a specific pigment anomaly affecting common dab Limanda limanda in the North Sea and, less frequently, in adjacent areas, e.g. the English Channel, Irish and Celtic Seas, western Baltic Sea and Icelandic waters. Other North Sea flatfish species are also affected, but at a markedly lower by: 7.

The fish were held under natural photoperiod from hatching (July) until the start of the experiment in by: Data from three annual surveys, covering inshore and offshore waters of the southeastern North Sea, were analysed to study recruitment variability in dab (Limanda limanda.

In the dab, Limanda limanda, exposure to accelerated photoperiod at 11°C in six months similar in pattern to a normal year's cycle resulted in the formation of ripe eggs months ahead of the season, while in turbot, Scophthalmus maximus and Solea solea, long photoperiod (LD or ) induced formation of ripe eggs (Htun-Han, ).

Mean CV of age estimation was % which means that the age reading process was significantly precise.
