Effects of Thermal Effluent on the Fat Content of the Mosquito Fish
Janet D. Flake and Michael H. Smith
Mosquito fish were collected at the Savannah River
Plant from seven locations, three areas receiving thermal effluent, one thermal
recovery area, and three natural areas. Percentage
of fat in each fish was determined and was correlated with the log of the dry
weight, but not with standard length. Females
had significantly more fat than males at all locations except one.
Significant differences in fat content were attributable to location, but
no correlation was found between percentage of fat and habitat temperature.
Several hypotheses may help to explain the data, but it seems likely that
Gambusia affinis is naturally a eurythermal species.
Southern populations of this species should be useful in stocking
programs that are part of reactor construction plans.
