Effect of water-soluble fraction of Cook Inlet crude oil on swimming performance and plasma cortisol in juvenile coho salmon (Oncorhynchus kisutch).
Swimming performance of juvenile coho salmon decreased and plasma cortisol increased, following 48-hr exposure to the water-soluble fraction (WSF) of Cook Inlet crude oil at 75% of the LC50. Exposure to 25 and 50% of the LC50 did not significantly reduce swimming performance. Plasma cortisol concentrations were highest in fish exposed to both the combined stress of WSF exposure and of forced swimming in a stamina tunnel.
