Abstract

The survival of cod Gadus morhua, plaice Pleuronectes platessa, and dab Limanda limanda was determined in relation to ambient oxygen saturation at 8° C and 35% m salinity. Mortalit rates were observed in fish exposed to constant oxygen levels for 24h. First mortality occurred around 60 % oxygen saturation in cod and around 30% oxygen saturation in dab and plaice. Below these thresholds mortality increased linearly with decreasing oxygen levels. If cod were infested with 1 or 2 individuals of Lernaeocera branchialis (Copepoda), their tolerance was significantly lower; under such circumstances the incipient lethal oxygen saturation was 66 %.
