Abstract
Northern pike (Esox lucius) are large ambush predators of other fish in
northern temperate lakes. Cook and Bergersen (1998) found that in the summer
these fish tend to occupy shallow water with large amounts of vegetation. They also
reported that the pike in their study showed low levels of activity with most activity
occurring at dawn or dusk.
Some studies (Minns, 1995) have suggested a correlation between a fish’s
size and the size of it’s home range. Others (Jepsen et al., 2001) suggest that
individual fish within populations show different hunting behavior based on
preference and prey availability. Some fish stay in one small area, some remain in a
few favorite areas, and others move frequently and lack a distinct home range.
Jepsen et al. suggest that in areas with higher prey density a small home range may
be possible, while areas with low prey density may force the fish to move more
frequently.
Our study focused on the home range size and average depth of pike
and whether these were correlated to the length of the fish. We also took data on
the vegetation types, water temperature, and activity patterns but due to time
constraints we were unable to analyze this data in depth. It is included in our raw
data in Appendix B for future uses.
