Abstract | The food composition of 0-group sole Solea solea, dab Limanda limanda and plaice Pleuronectes platessa on a nursery ground at Gravelines, France, included 17-25 taxa. Sole (new settlers) fed mainly on harpacticoid copepods and when 50mm in size, on polychaetes (Terebellidae). Dab (<40mm) consumed mainly polychaetes (Magelonidae and Spionidae), and later amphipods, polychaetes (Spionidae) and Hydrozoa. 0-group plaice diet was dominated by polychaetes (Terebellidae), crustaceans and molluscs at all sizes. 0-group sole, dab and plaice did not compete for food resources, each species being specialized in different prey items. Growth rates during May-July 1998 varied between 0.5 and 0.67mm day-1 for sole, 0.12 and 0.24mm day-1 for dab and 0.55 and 0.81mm day-1 for plaice. For sole and plaice, these estimates were similar to those recorded in other nurseries and also close to the maximal growth predicted by experimental models. This suggests that their growth was not limited by food during the first summer of life. |
