Adult longhorn sculpins were collected from Conception Bay, Newfoundland, and infected with trypanosomes via leeches. One group of these fish were exposed to water-accommodated Venezuelan crude oil, while the other served as controls. The results of the study suggests that water soluble fractions of Venezuelan crude oil have a minor effect on the hematology of sculpins in the concentration range 150-300 ppb, but that trypanosomes appear to potentiate the effect of oil on blood hemoglobin content of trypanosome infected fish. If this is found to be the case in active species of fish, the decrease in oxygen carrying capacity would likely limit the aerobic capacity of fish. (JMT)
