INTRODUCTION Fish populations can fluctuate due to natural forces (weather, predation, competition), management actions (stocking, regulations, habitat improvement), inappropriate development (habitat degradation), and harvest impacts. Wisconsin Department of Natural Resources fisheries crews regularly conduct fishery surveys on area lakes and reservoirs to gather the information needed to monitor changes, identify concerns, evaluate past management actions, and to prescribe good fishery management strategies. Netting and electrofishing surveys are used to gather data on the status of fish populations and communities (species composition, population size, reproductive success, size/age distribution, and growth rates). But the other key component of the fishery that we often need to measure is the 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 harvest to assess its impact on the fishery. But because it would be highly impractical and very costly to conduct a complete census of every angler who fishes on a lake, 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 of harvest and other fishery parameters. Creel survey clerks work on randomly-selected

days and shifts, forty hours per week during the open season for gamefish from the first Saturday in May through the first Sunday in March, except during the month of 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 numbers of anglers on a lake at predetermined times, and to interview anglers who have completed their fishing trip to collect data on what species they fished for, catch, harvest, lengths of fish harvested, marks (finclips 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 make projections of total catch and harvest of each species, catch and harvest rates, and total fishing effort, by month and for the year in total. Keep in mind that these are only projections based on the best information available, and not a complete accounting of effort, catch, and harvest. Accurate projections require that we sample a sufficient and representative portion of the angling activity on a lake. The accuracy of creel survey results, therefore, 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 moment of your time and it gives the Department valuable information needed for management of the fishery.

This report provides projections of: 1. Overall fishing effort (pressure) 2. Fishing effort directed at each species 3. Catch and harvest rates 4. Numbers of fish caught and harvested Also included are a physical description of Big Saint Germain Lake; discussion of results of the survey; and detailed summaries, by species of fishing effort, catch and harvest. GENERAL LAKE INFORMATION

Location Big Saint Germain Lake is located in Vilas County in the Town of Saint Germain. Physical Characteristics Big Saint Germain Lake is a 1,617 acre drainage lake with a maximum depth of 42 feet. Content and Fawn Lake, which are connected to Big Saint Germain, are not part of the projections in this report. Littoral substrate consists primarily of sand, with some gravel, rock and muck. Big Saint Germain Lake is a moderately fertile lake with alkaline, clear water of moderate transparency. Seasons Surveyed The period referred to in this report as the 2011-12 fishing season ran from May 7, 2011 through March 4, 2012. The open water creel survey ran from May 7 through

October 31, 2011 and the ice fishing creel survey ran from December 1, 2012 through March 4, 2012. Weather Ice-out on Big Saint Germain Lake was around April 27, 2011. Fishable-ice formed on Big Saint Germain Lake in mid December. Sportfishing Regulations The following seasons, daily bag limits, and length limits were in place on Big Saint Germain Lake during the 2011-12 fishing season: Largemouth Bass& 5/7-6/17 Catch&ReleaseSmallmouth Bass 6/18-3/4 5 14"Musky 5/28-11/30 1 34"Northern Pike 5/7-3/4 5 noneWalleye 5/7-3/4 2* 15"Panfish year round 25 noneRock Bass year round none none

* The statewide bag limit was 5

walleye, but due to tribal declarations it was reduced on Big Saint Germain Lake.

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. PROJECTED FISHING EFFORT Total calculated number of hours

during each month that anglers spent fishing for a species.

2. PROJECTED SPECIFIC CATCH

Big Saint Germain Lake

3

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.

3. PROJECTED CATCH AND

HARVEST Calculated number of fish of the

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

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 those fish measured by the creel survey clerk are reported.

CREEL SURVEY RESULTS AND DISCUSSION Survey Logistics The creel survey went well. We encountered no unusual problems conducting the survey or calculating the projections contained in the report. This was the second time the department conducted a creel survey on Big Saint Germain Lake. The last creel of Big Saint Germain Lake took place in 1994-95. General Angler Information Anglers spent 71,260 hours or 39.3 hours per acre fishing Big Saint Germain Lake during the 2011-12 season (Table 1). That was more than the Vilas County average of 34.6 hours per acre. July was the most

heavily fished month (12.0 hours per acre). Fishing effort was lightest in December (0.9 hours per acre) for those months when the entire month was creeled. RESULTS BY SPECIES Walleye (Table 2, Figure 1) Walleyes received the most fishing effort during the 2011-12 season. Anglers spent 24,952 hours targeting walleyes. The greatest fishing effort for walleyes was in July (8,498 hours). October had the least amount of walleye fishing effort (318 hours). Total catch of walleyes was 3,506 fish with a harvest of 1,588 fish. Highest catch (1486 fish) and harvest (789 fish) occurred in July. Anglers fished 7.5 hours to catch and 16.2 hours to harvest a walleye during 2011-12. The mean length of harvested walleyes was 19.4 inches and the largest walleye measured was a 28.5 inch fish. Northern Pike (Table 2, Figure 2) Fishing effort directed at northern pike was 8,535 hours during the 2011-12 season. Northern pike fishing effort was greatest in January (2,277 hours). Total catch of northern pike was 3,496 fish with a harvest of 941 fish. The mean length of harvested northern pike was 24.2 inches and the largest northern pike measured was a 33.5 inch fish. Muskellunge (Table 2, Figure 3) Anglers spent 15,320 hours targeting muskellunge during the 2011-12 season. Muskellunge fishing effort was greatest in September (5,372 hours). Total catch of muskellunge was 390 fish. Highest catch (149 fish) occurred in

4

September. Anglers fished 48.5 hours to catch a muskellunge and none were reported harvested during 2011-12. Smallmouth Bass (Table 2, Figure 4) Fishing effort targeted at smallmouth bass was 6,796 hours during the 2011-12 season. Smallmouth bass fishing effort was greatest in July (4,872 hours). Total catch of smallmouth bass was 6,175 fish with 353 harvested. Highest catch (3,386 fish) occurred in July. Anglers fished 2.4 hours to catch a smallmouth bass during 2011-12. Largemouth Bass (Table 2, Figure 5) Fishing effort directed at largemouth bass was 2,044 hours during the 2011-12 season. Largemouth bass fishing effort was greatest in September (1,014 hours). Total catch of largemouth bass was 1,478 fish with a harvest of 44 fish. Highest catch (590 fish) occurred in July. Anglers fished 3.6 hours to catch a largemouth bass during 2011-12. 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 15,568 hours. Total catch of yellow perch was 33,954 fish with 6,418 harvested. The mean length of yellow perch harvested was 8.4 inches. Black crappies were the second most sought after panfish species during the survey. Fishing effort directed at black crappies was 15,341 hours. Anglers caught 9,696 black crappies and harvested 6,288 fish. The mean length of black crappies harvested was 10.5 inches.

Bluegills were the third sought after panfish species during the survey. Fishing effort directed at bluegills was 12,054 hours. Total catch of bluegills was 34,363 fish with 8,891 harvested. The mean length of bluegills harvested was 7.3 inches. Pumpkinseeds and rock bass were also caught during the 2011-12 season. ACKNOWLEDGMENTS Completion of this survey was possible because of the efforts of the technical staff of the fisheries management and Treaty Fisheries Unit. Treaty staff responsible for ensuring completion of this survey included Jeff Blonski, Joelle Underwood, Marty Kiepke, Jason Halverson, and Tim Tobias. Marty Kiepke and Jeff Blonski were the creel clerks on Big Saint Germain Lake during the survey period. We also 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. The department thanks the cooperators, Forest Downs Rec Corporation and Fibbers Restaurant, who generously allowed the department to keep a boat and snowmobile on their property during this survey. This creel report was reviewed by, Steve Gilbert and Dennis Scholl 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/fish/ceded/reports.html
