title: Effect of water-soluble fraction of Cook Inlet crude oil on swimming performance and plasma cortisol in juvenile coho salmon (Oncorhynchus kisutch).
abstract: 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.
