Periodic regression results; N = 29 in all cases. Top catch is the catch of the most experienced anglers.

aCatch and CPUE models.bEffort models.cThe familywise significance rate (α) for 8 geographic group F-tests using the Muskies Inc. catch data is 0.006; the familywise significance rate for 6 tests using the creel data is 0.009.dThe percent increase in predicted number of muskellunge caught or predicted hours fished on the peak days relative to catch or fishing effort on random days. For catch, the maximum relative effect was calculated using back-transformed predicted catch.eAll catch models except “Night” excluded nighttime records and records from November – May.fIncludes all night records except records from November – May.gNd = not determined (regression F not significant).hExcludes nighttime records and records from November – May.
