Adenosine deaminase (ADA), lactate dehydrogenase (LDH),
and malate dehydrogenase (MDH) activity levels were measured in mosquitofish
populations from contrasting natural environments.
Significant differences in enzyme level, in the level of soluble protein,
and in length and weight were observed among populations from different
habitats. MDH and LDH activities
were highest in running-water populations, whereas ADA was elevated in coastal
environments. Still-water females
were longer and weighed less than running-water females.
The regression relationships of length vs. weight and protein vs. weight
also varied significantly among populations.
The proportion of enzyme activity variation which could be accounted for
by habitat, location, or log length was not the same for the three enzymes,
suggesting that biological and physical factors influence the activities of
various enzymes in different ways.
