Inferences regarding predation on the early life stages of cod and other fishes. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983

Abstract

Little information exists on the predation on the early life stages of marine fish in general and even less on cod. Thus the approach used in this review was to infer the predatory processes that may be significant in the early life history of cod using the general literature on the predators of marine fish eggs and larvae. The mortality of cod during the embryonic period is high indicating a high rate of predation and predation may continue to be the dominant source of mortality in later larval stages. The known predators of eggs and larvae are discussed as are intrinsic and extrinsic factors that affect vulnerability to predation. Recommendations are made for future research.
