摘要: The food composition of O-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 harpacticoid copepods when ≥ 50 mm in size, polychaetes (Terebellidae). Dab (<40 mm) consumed (Magelonidae Spionidae), later amphipods, (Spionidae) Hydrozoa. diet was dominated by (Terebellidae), crustaceans molluscs all sizes. sole. did not compete for resources, each species being specialized different prey items. Growth rates during May-July 1998 varied between 0.5 0.67 day -1 sole, 0.12 0.24 0.55 0.81 plaice. For plaice, these estimates were similar to those recorded other nurseries also close the maximal growth predicted experimental models. This suggests that their limited first summer life.
