Abstract.-This report summarizes
results of on-site creel surveys conducted on inland lakes, rivers,
and the Great Lakes from 1975 to 1982 which are not given in other
reports.
The inland lake fisheries varied considerably. For
a May-September fishing season, total catch varied from 0.09 to
559 fish per acre, and catch rate from 0.0051 to 2.5861 fish per
angler hour. Generally, fishing pressure was inversely related
to lake size and was highest in Region III (southern Michigan).
Large lakes tended to have lower catch per acre and lower catch
per hour averages. Limited comparisons suggest that there has
been a decline in inland lake fisheries since 1946-65 surveys.
Statistics for 13 Great Lakes surveys are given in
this report. Fish per hour estimates ranged from a high of 2.12
for the Saginaw Bay winter perch fishery to a low of 0.253 for
the Thunder Bay summer trout fishery. Fishing pressure ranged
from a high of 15,156 hours per square mile for the 1978 summer
Belle Isle fishery to a low of 341 hours per square mile the above-mentioned
Thunder Bay fishery.
Five river fisheries were surveyed. Catch rates ranged
from a high of 0.4354 fish per hour per angler for the Detroit
River to a low of 0.0356 fish per hour per angler on the lower
Au Sable River. The Detroit River had the highest fishing pressure,
22,709 fishing hours per linear mile, and the St. Joseph had the
lowest, 2,958 fishing hours per linear mile.
Recommendations for planning creel surveys are given.
