Relationship between minimum ping frequency and estimates of the number of forays by individual lake trout into the littoral zone of L373 during the (A) spring (n = 54), (B) summer (n = 46), and (C) fall (n = 36) periods of 2003 and 2004. Points represent estimates for individual fish in a given year at each minimum ping frequency. The slope of the relationship between minimum ping frequency and corresponding estimates of the number of littoral forays did not differ by year for either spring or summer, and estimates of the mean number of littoral forays also did not differ by year for either season. The best-fit equation in A was log(y) = −0.0016x + 2.13 and in B was log(y) = −0.0027x + 1.87, where x is the minimum ping frequency and y is the estimate of the number of littoral forays. For fall, the number of littoral forays estimated was not influenced by minimum ping frequency, year, or their interaction.
