Thermal shock tolerances of six fishes and one invertebrate from the Pacific Northwest
The purpose of this study was to ascertain the temperatures at which selected estuarine fishes from the Pacific Northwest and one of their potential food organisms would be incapacitated and killed after entering the thermal plume of an industrial cooling system. This information aids in impact evaluation of thermal discharges, especially where they act as barriers or entrapments. Data are presented from laboratory studies of equilibrium loss and thermal death as endpoints for different rates of temperature increase of six fishes and one invertebrate. The species tested were shiner perch, Cymatogaster aggregata; coho salmon, Onchorhynchus kisutch; Pacific sandlance, Ammodytes hexapterus; threespine stickleback, Gasterosteous aculeatus; silverspotted sculpin, Blepsias cirrhosus; Pacific staghorn sculpin, Leptocottus armatus; and the mysid, Mysis oculata collected from Sequim Bay, Washington. The null hypothesis that no differences exist between mean temperatures for equilibrium loss or death for different rates of temperature increase, allowing for possible effects of length and weight, was tested by analysis of covariance.
