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 or 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.

This report provides estimates of: 1. Overall fishing effort (pressure) 2. Fishing effort directed at each species 3. Numbers of fish caught and harvested 4. Catch and harvest rates Also included are a physical description of Little Arbor Vitae Lake; discussion of results of the survey; and detailed summaries by species of fishing effort, catch and harvest. GENERAL LAKE INFORMATION
Location Little Arbor Vitae Lake is located in Vilas County near the town of Arbor Vitae. Physical Characteristics Little Arbor Vitae Lake is a 534-acre drainage lake with a maximum depth of 32 feet. Littoral substrate consists primarily of sand, gravel and muck, with lesser amounts of muck and boulders. Little Arbor Vitae Lake contains medium-hard, alkaline, clear water of moderate to low transparency. Seasons Surveyed The period referred to in this report as the 2017-18 fishing season ran from May 6, 2017 through March 4, 2018. The open-water creel survey ran from May 6 through October 31, 2017, and the ice fishing creel survey ran from December 1, 2017 through March 4, 2018.
Weather Ice-out on Little Arbor Vitae Lake was around April 10, 2017. Fishable ice formed on Little Arbor Vitae Lake in mid-December. Fishing Regulations The following seasons, daily bag limits, and length limits were in place on Little Arbor Vitae Lake during the 2017-18 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 4 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 fifth time the Department conducted a creel survey on Little Arbor Vitae Lake. The last creel survey took place in 2007-08. General Angler Information Anglers spent 30,040 hours, or 56.3 hours per acre, fishing Little Arbor Vitae Lake during the 2017-18 season (Table 1). That was more than the Vilas County average of 34.8 hours per acre, and more than the fishing effort documented during the 2007-08 creel survey (47.3 hours per acre). June was the most heavily fished month (10.6 hours), and fishing effort was lightest in December (0.9 hours). The creel clerks were able to conduct 1,068 interviews throughout the survey.
RESULTS BY SPECIES
Walleye (Table 2, Figure 1) Walleye received the most fishing effort of any gamefish species during the season. Anglers spent 12,023 hours targeting Walleye. The greatest fishing effort for Walleye was in July (2,268 hours). December had the least amount of Walleye fishing effort (319 hours).
Total catch of Walleye was 3,368 fish, with a harvest of 1,698. Highest catch (976 fish) and highest harvest (547 fish) occurred in June. Anglers fished an average of 3.9 hours to catch, and 7.8 hours to harvest, a Walleye during the survey. The mean length of harvested Walleye was 15.3 inches, and the largest measured was a 26.8- inch fish.

Bowfin and Mottled Sculpin were also caught at low numbers in Little Arbor Vitae Lake.
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, Jeff McKnight and Family of Butler Bay Resort, who generously allowed the Department to keep a boat and 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, Steve Gilbert, Tim Tobias, and Hadley Boehm. Creel clerks on Little Arbor Vitae Lake during the survey period were Matt Lorenzoni and April Mikul.
This creel report was reviewed by John Kubisiak, Lawrence Eslinger, and Hadley Boehm 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, Little Arbor Vitae Lake, 2017-18 season compared with 2007-08 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 Little Arbor Vitae 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 Little Arbor Vitae 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 Little Arbor Vitae Lake to other lakes.
2007-08 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 Little Arbor Vitae Lake.
