INTRODUCTION In a previous paper (Paz and Larrafieta, 1989) we obtained a significant positive correlation between cod year-class size in Div. 3NO and American plaice spawning biomass in Div. 3LNO, that was interpreted by supposing a strong predation of 0-group cod on 0-group American plaice. On the contrary, we have not found significant correlations between cod year-classes and spawning biomasses of other species in the area as redfish, yellowtail and mackerel. Following the same method, in this paper we explore correlations between American plaice (Hippoglossoides platessoides) and yellowtail flounder (Limanda ferruginea) year-class sizes and biomasses of adult fishes of these species and those of cod (Cactus morhua), mackerel (Scomber seombrus) and redfishes (Sebastes app. )
