INTRODUCTION Fish populations can fluctuate due to natural forces like weather, predation or competition; management actions like stocking, regulations or habitat improvement; habitat loss and harvest impacts. Wisconsin Department of Natural Resources fisheries crews regularly conduct fishery surveys on lakes and reservoirs to gather the information needed to monitor changes, identify concerns, evaluate past management actions, and to prescribe fishery management strategies. Netting and electrofishing surveys are used to gather data on the status of fish populations and communities, measuring such parameters as species composition, population size, reproductive success, size and age distribution and growth rates. The other key component of the fishery that we often need to measure is harvest. On many lakes in the Ceded Territory of northern Wisconsin, harvest of fish is divided between sport anglers and the six Chippewa tribes who harvest fish under rights granted by federal treaties. The tribes harvest fish mostly using a highly efficient method, spearing, during a relatively short time period in the spring. Every fish in the spear harvest is counted – a complete “census” of the harvest. We also measure the sport angler harvest to assess its impact on the fishery. However, it would be highly impractical and very costly to conduct a complete census of every angler who fishes on a lake. Therefore, we conduct creel surveys. A creel survey is an assessment tool used to sample the fishing activities of anglers on a body of water and make projections, or estimates, of harvest and other fishery parameters. Creel survey clerks work on randomly-selected days and shifts, forty

hours per week. The survey is conducted during the open season for gamefish from the first Saturday in May through the first Sunday in March. Creel surveys are not conducted in November when fishing effort is low and ice conditions are often unsafe. The survey is run during daylight hours, and shift times change from month to month as day length changes. Creel survey clerks travel their lakes using a boat or snowmobile to count the number of anglers at predetermined times, and to interview anglers who have completed their fishing trip. Data is collected on what species they fished for, catch, harvest, lengths of fish harvested, marks (fin clips or tags), and hours of fishing effort. Collecting completed-trip data provides the most accurate assessment of angling activities, and it avoids the need to disturb anglers while they are fishing. A computer program is used to estimate catch and harvest of each species, catch and harvest rates, and fishing effort by month, as well as for the year in total. Keep in mind that these are estimates based on the best information available, and not a complete accounting of effort, catch, and harvest. Accurate estimates require that we sample a sufficient and representative portion of the angling activity on a lake. The accuracy of creel survey results depends on good cooperation and truthful responses by anglers when a creel clerk interviews them. You may have encountered a DNR creel survey clerk on a recent fishing trip. We appreciate your cooperation during an interview. The survey only takes a few minutes of your time, and it gives the Department valuable information needed for management of the fishery.

Catch and harvest rates Also included are a physical description of Plum Lake; discussion of results of the survey; and detailed summaries by species of fishing effort, catch and harvest. GENERAL LAKE INFORMATION

Location Plum Lake is located in Vilas County in the town of Plum Lake. Physical Characteristics Plum Lake is a 1,033 acre drainage lake with a maximum depth of 57 feet. Littoral substrate consists primarily of sand, gravel, and muck, with some rocks also present. Plum Lake contains soft, slightly acidic, clear water of moderate transparency. Seasons Surveyed The period referred to in this report as the 2018-19 fishing season ran from May 5, 2018 through March 3, 2019. The open-water creel survey ran from May 5 through October 31, 2018, and the ice fishing creel survey ran from December 1, 2018 through March 3, 2019. Weather Ice-out on Plum Lake was around May 8, 2018. Fishable ice formed on Plum Lake

in early-December. Deep snow during the second half of February made ice travel difficult and resulted in low fishing effort during late February and March. Fishing Regulations The following seasons, daily bag limits, and length limits were in place on Plum Lake during the 2018-19 fishing season:

SPECIES CATCH AND HARVEST INFORMATION Angling effort, catch, and harvest information is summarized for each species in Table 2 and Figures 1-10. Table 2 also includes a comparison of these statistics with the previous creel survey. Information presented about species whose fishing season extends beyond March 3 should be considered minimum estimates. Each species page has up to five graphs depicting the following: 1. ESTIMATED FISHING EFFORT Total calculated number of hours

during each month that anglers spent fishing for a species.

2. ESTIMATED CATCH AND

HARVEST Calculated number of fish of the

indicated species caught or harvested by all anglers, regardless of targeted species.

3. ESTIMATED SPECIFIC CATCH AND HARVEST RATES

Calculated number of hours it takes an angler to catch or harvest a fish of the indicated species. Only information from anglers who were specifically targeting that species is reported.

4. LENGTH DISTRIBUTION OF

HARVESTED FISH All fish of a species that were

measured by the clerk during the entire creel survey season.

5. LARGEST AND AVERAGE

LENGTH OF HARVESTED FISH Monthly largest and average length

of harvested fish of a species. Only fish measured by the creel survey clerk are reported.

CREEL SURVEY RESULTS AND DISCUSSION Survey Logistics We encountered no unusual problems conducting the survey or calculating the projections contained in the report. This was the eighth time the Department conducted a creel survey on Plum Lake. The last creel survey took place in 2015-16. General Angler Information Anglers spent 18,989 hours, or 18.4 hours per acre, fishing Plum Lake during the 2018-19 season (Table 1). That was less than the Vilas County average of 34.5 hours per acre, and similar to the fishing effort documented during the 2015-16 creel survey (19.9 hours per acre). August was the most heavily fished month (3,333 hours), and fishing effort was lightest in January (259 hours). The creel clerks were able to conduct 569 interviews throughout the survey.

RESULTS BY SPECIES Walleye (Table 2, Figure 1) Fishing effort targeted at Walleye was 6,240 hours during the season. The greatest fishing effort for Walleye was in September (1,029 hours). January had the least amount of Walleye fishing effort (169 hours). Total catch of Walleye was 717 fish, with a harvest of 67. Highest catch (158 fish) occurred in September, and highest harvest (37 fish) occurred in May. Anglers fished an average of 10.0 hours to catch, and 105.3 hours to harvest, a Walleye during the survey. The mean length of harvested Walleye was 17.7 inches, and the largest measured was a 22.5-inch fish. Northern Pike (Table 2, Figure 2) Fishing effort directed at Northern Pike was 5,823 hours during the season. Northern Pike fishing effort was greatest in February (1,686 hours). Total catch of Northern Pike was 5,200 fish, with a harvest of 628. Anglers fished an average of 1.7 hours to catch a Northern Pike during the survey. The mean length of harvested Northern Pike was 20.5 inches, and the largest measured was a 29.9-inch fish. Muskellunge (Table 2, Figure 3) Anglers spent 3,025 hours targeting Muskellunge during the season. Muskellunge fishing effort was greatest in August (822 hours). Total catch of Muskellunge was 33 fish, and the highest catch (11 fish) occurred in July. Anglers fished 102.0 hours to catch a Muskellunge, and there was no documented harvest during the survey. Smallmouth Bass (Table 2, Figure 4) Smallmouth Bass received the most fishing effort of any gamefish species during the season. Anglers spent 6,562 hours targeting Smallmouth Bass. Fishing effort

4

was greatest in May (1,478 hours). Total catch of Smallmouth Bass was 1,773 fish, with 23 harvested. Highest catch (673 fish) occurred in May. Anglers fished an average of 4.1 hours to catch a Smallmouth Bass during the survey. Largemouth Bass (Table 2, Figure 5) Fishing effort directed at Largemouth Bass was 2,433 hours during the season. Largemouth Bass fishing effort was greatest in August (705 hours). Total catch of Largemouth Bass was 645 fish, with a harvest of four. Highest catch (182 fish) occurred in August. Anglers fished an average of 7.0 hours to catch a Largemouth Bass during the survey. Panfish (Table 2, Figures 6-10) Yellow Perch were the most sought after panfish species during the survey. Fishing effort directed at Yellow Perch was 5,306 hours. Total catch of Yellow Perch was 3,743 fish, with 622 harvested. The mean length of Yellow Perch harvested was 8.6 inches. Bluegill received 5,019 hours of directed fishing effort. Total catch of Bluegill was 5,812 fish, with 1,039 harvested. The mean length of Bluegill harvested was 7.7 inches. Black Crappie received 3,857 hours of directed fishing effort. Anglers caught 198 Black Crappie and harvested 70. The mean length of Black Crappie harvested was 10.4 inches. Pumpkinseed received 264 hours of directed fishing effort. Anglers caught 352 Pumpkinseed and harvested 102. The mean length of Pumpkinseed harvested was 7.0 inches.

Rock Bass received only 21 hours of directed fishing effort. However, anglers caught 87 Rock Bass and harvested four. The mean length of Rock Bass harvested was 9.4 inches. ACKNOWLEDGMENTS The Department would like to thank all the anglers who took the time to offer information about their fishing trip to the survey clerk. Without their cooperation, the survey would not have been possible. We also thank our cooperators, Meadow Lofty of Plum Gate Resort and Sam Patterson of Plum Lake Golf Course, who generously allowed the Department to keep a boat and/or snowmobile on their property during this survey. Completion of this survey was possible because of the efforts of the following fisheries management and treaty fisheries staff: Lawrence Eslinger, Jeff Blonski, Joelle Underwood, Jason Halverson, John Kubisiak, Bob Consolo, Steve Gilbert, Hadley Boehm, and Tim Tobias. Creel clerks on Plum Lake during the survey period were Richard Cechal, Steve Timler, Marty Kiepke, and Eric Brown. This creel report was reviewed by John Kubisiak, Lawrence Eslinger, and Steve Gilbert of the Wisconsin Department of Natural Resources, Woodruff, Wisconsin. Additional copies of this report, and those covering other local lakes, can be obtained from the Woodruff DNR or online at: http://dnr.wi.gov/topic/Fishing/north/trtycrlsrvys.html

Table 1. Sportfishing effort summary, Plum Lake, 2018-19 season; compared to 2015-16 creel results, Vilas County, and Ceded Territory averages.

County Average Hours/Acre is the average angler effort in hours per acre for county lakes that have been surveyed since 1990. This value is useful for fishing pressure comparisons with other waters.

Ceded Territory Average Hours/Acre is the average angler effort in hours per acre for inland lakes in the Ceded Territory that have been surveyed since 1990. This value can be used to compare Plum Lake to other lakes in northern Wisconsin.

Number of Angler Party Interviews is the number of groups of anglers interviewed by the creel clerk. A party is considered the members of a group who fish together in the same boat, ice shanty, or from shore. The clerk fills out one interview form for each group of anglers. The number of individual anglers actually contacted by the clerk is usually much greater than the number of groups listed in this table since most groups consist of more than one angler.

Total Angler Hours is the estimated total number of hours that anglers spent fishing on Plum Lake during each month surveyed.

Total Angler Hours/Acre is the total angler hours divided by the area of the lake in acres. This is useful in order to compare effort on Plum Lake to other lakes.

2015-16 Total Angler Hours/Acre is the total angler hours divided by the area of the lake in acres. This is from the previous creel survey that took place on Plum Lake.
