Impairment of feeding behavior of the spottail shiner (Notropis hudsonius) by metacercariae of the digenetic trematode Diplostomum flexicaudum.
(2004)
The spottail shiner (Notropis hudsonius) was infected in the laboratory with cercariae of the eye fluke Diplostomum flexicaudum to determine if infection by the parasite impaired feeding behavior of the fish. The mean and ...
A comparison of the maneuverability of bluegill and sunfish to that of minnows.
(1993)
The purpose of conducting this experiment is to determine which has more maneuverability--bluegills and sunfish or minnows? It will be interesting to determine the answer to this question as each of these two types of fish ...
