86-4 FISHERIES DIVISION TECHNICAL REPORT I Creel Survey of Sportfishing in Saginaw Bay, Lake Huron, 1983-84 9 Number 86-4 I I I I U I, II I Michigan Department of Natural Resources ERRATA MICHIGAN DEPARTMENT OF NATURAL RESOURCES FISHERIES DIVISION Technical Report 86-4 Please replace second paragraph, page 6. Another year-to-year comparison could be made with the 1984 data from Arenac and northern Bay counties using similar ice fishing data collected from 1974 to 1978 (Weber 1985). The three statistics compared were the number of perch caught, the hours spent fishing, and the number of f ishing trips made by anglers. The 1977-78 ice f ishing season had the most perch caught (501,806 ~43,851); 1983-84 had the highest numbers of angler hours (218,7536 ~ 36,079) and angler trips (73,173 ~ 11,151). The 1975-1976 ice fishing season had the lowest estimated perch catch (41,583 ~ 26,988) and the 1976-1977 ice fishing season had the lowest number of angler hours (47,872+~16,839) and angler trips (6,539 ~1,858). These statistics are partly influenced annually again by the year class strength of yellow perch and are strongly influenced by the length of the season or by the length of time ice covers the bay (Ryckman and Lockwood 1985). These data are summarized monthly in Table 13. MICHIGAN DEPARTMENT OF NATURAL RESOURCES FISHERIES DIVISION Fisheries Technical Report 86-4 June 26, 1986 A CREEL SURVEY OF SPORTFISHING IN SAGINAW BAY, LAKE HURON, 1983-841 James R. Ryckman 'Contribution from Dingell-Johnson Project F-53-R, Michigan 2 ABSTRACT A creel survey was conducted in four counties on Saginaw Bay from the spring season of 1983 to the spring season of 1984. During this 13- month period anglers fished an estimated total of 1,,720,054 hours. Thirty -nine percent of this fishing effort was expended from May through November 1983. Sixty -one percent of the effort occurred from January through May 1984. Essentially no fishing occurred during the month of December 1983. Anglers caught an estimated 3,829,868 fish of all species from May 1983 through May 1984. Forty percent of these fish were caught from May through November 1983. The remaining 60% of the catch occurred from January through May 1984. Ninety -four percent of the May through November 1983 catch was yellow perch. This species made up 97% of the total catch from January through May 1984. The catch of yellow perch had an average length of 7.6 inches. Catch rates for this 13-month period were 2.2266 total fish per hour per angler and 2.1347 yellow perch per hour per angler. A comparison of the months of May 1983 and May 1984 showed much higher fishing pressure, total catch, and yellow perch catch in the latter year than in 1983. Catch rates for May for both years were not significantly different. The month of May 1984 had the highest fishing pressure of any month surveyed. This estimated pressure was 220,931 angler hours. The month of August 1983 had the highest catch of total fish and catch of yellow perch. These estimates were 498,816 and 492,739, respectively. A comparison of the number of yellow perch caught per month and number of angler hours spent fishing showed a high correlation (r = 0.8332). 3 INTRODUCTION Saginaw Bay is located on the eastern side of Michigan's lower peninsula in the Lake Huron watershed. It is approximately 60 miles long and its axis runs in a southwesterlynortheasterly direction. The lower end of the bay is approximately midway between the northern and southern boundaries of Michigan's lower peninsula. The width of the bay varies from 18 to 30 miles. Its major tributary is the Saginaw River, which enters at the southwestern end of the bay at Bay City. This body of water has long been noted for its sport and commercial fisheries. The primary species caught by anglers and commercial fishermen is the yellow perch. Concern about the health of the yellow perch population stimulated a survey to measure the annual catch and effort for the sport fishery in a four county area. METHODS A creel census was begun in the spring of 1983 for the Saginaw Bay waters of Arenac, Bay, Huron, and Tuscola counties. Three of the four counties (Bay, Huron, and Tuscola) were censused from March 1983 to the end of May 1984. The northern-most county, Arenac, was censused from May 1983 through May 1984. losco County also borders the extreme northern end of Saginaw Bay, but it was decided that this area more nearly matched Lake Huron proper and, therefore, was not included in this survey. This survey includes all of the area of Saginaw Bay southwest of a line from the IoscoArenac county line to the tip of the thumb of Michigan (Port Austin in Huron County, Fig. 1). Interviews were collected on-site by clerks according to stratified random schedules (Ryckman 1981). Five census clerks collected interviews during the open-water season and four clerks worked during the ice fishing season. The interviews provided catch rates (catch per hour) by species, species sought information, residence of anglers, length of an angler trip, and number of fishing trips taken by each angler each day. Fishing pressure counts were made once a day by airplane, on 3 weekdays and 2 weekend days per week during the open-water season (March-November 1983 and April-May 1984). The counts from the plane were also made on a stratified random schedule (morning vs aqfternoon and weekday vs weekend). The direction of the flight of the plane, within a monthly period, was also randomly selected to eliminate any time of day bias in the angler counts. The counting was done by both a clerk accompanying the pilot and the pilot to insure accuracy. Individual shore anglers and fishing boats were counted during the open -water season. During the ice fishing season (January -March 1984) similar stratified counts were made by the clerks from the ground. This method was possible because the ice fishing occurred in fewer and more localized areas visible from the shore. 4 The average number of shore anglers per count per time strata during the open -water season and the average number of open -ice fishermen per count per time strata were calculated. These averages were multiplied by a corresponding expansion factor (number of days in a time strata x possible fishing hours in a day in a time strata) to provide estimates of angler hours. Boat hours and shanty hours were estimated similarly with the two following additions. First, estimates of the number of anglers per boat and per ice shanty were determined from interviews collected by the clerks and the appropriate expansion factors were multiplied by the original calculated boat hours and shanty hours to estimate angler hours for each fishery. Second, ice shanties were subsampled 2 or 3 days each, week (stratified by weekdays and weekends) to determine what percentage of them were actually being used for fishing. These percentages were used to adjust the original estimate of shanty fishing hours. All estimates were stratified by weekend and weekdays, month, fishing type, and county. All estimates and statistics in this report are given with confidence limits of two standard errors. A list of common and scientific names of fish caught by anglers is given in Appendix 1. RESULTS Anglers f ished an estimated 676,349 angler hours f rom May through November 1983 in the four counties censused. They caught 1,516,116 fish, of which 94% (1,427,937) were yellow perch (Table 1). Other important species caught were channel catf ish (35,550) and bullheads (19,294) (Table 2). Essentially no sportfishing occurred on Saginaw Bay in December 1983. Open -ice fishing and shanty fishing occurred from January through mid -March 1984, and shore and boat fishing occurred from mid-March through May 1984, when the census was terminated. For the January through May period, an estimated 1,043,705 angler hours were expended fishing on Saginaw Bay. The estimate of total fish caught was 2,313,752, of which 96.98% (2,243,,799) was yellow perch (Tables 1 and 3). The catch of rainbow smelt was of secondary importance. The highest monthly fishing effort, total catch, and yellow perch catch were during January 1984. These estimates were 371,514 angler hours, 802,248 total fish caught, and 785,745 yellow perch caught, respectively. The second highest estimated monthly fishing effort was in May 1984. This estimate was 220, 931 angler hours. The second highest 5 95.87~+17.81% of the total catch. The 13 -month average catch rates were 2.2266 ~0.3259 total fish per angler hour and 2.1347 ~0.3220 yellow perch per angler hour. The length -frequency distribution of 3,000 yellow perch taken from all areas fished f romn March 1983 through May 1984 (Weber 1985) indicates that of the 3,792,008 perch caught during this period 1,008,674 (26.60~0.05%) were in the 6.0-to 6.9-inch group; 1,418,211 (37.40~7.24%) were in the 7.0-to 7.9-inch group; 750,818 (19.80~3.99%) were in the 8.0 to 8.9 -inch group; and 329,905 (8.70 ~1.93%) were in the 9.0 - to 9.9 -inch group (Table 4). The average size of all angler caught perch f rom this sample was 7.63 ~0.04 inches. The total number of yellow perch caught each month from May 1983 through May 1984 showed a direct straight-line relationship with the number of angler hours fished each month. This relationship was: Total yellow perch catch = 1.946 x total number of angler hours fished per month. This relationship had a correlation coefficient (r) of 0.9128 (Fig. 2). This relationship was also tested using winter ice fishing data from Arenac County collected from 1974 through 1983 (Weber 1985). The relationship between the number of perch caught and the number of hours spent fishing was not significantly different from the 1983-1984 overall relationship for the entire four -county area surveyed (Fig. 2). The only month that could be used to compare year -to -year variation in the fishing (1983 vs 1984) for the entire four-county area censused was the month of May because no interviews were collected from Arenac County during March and April 1983. May 1984 had significantly higher fishing pressure, total catch of all species, and total catch of yellow perch than May 1983. The May 1984 catch and fishing pressure divided by the May 1983 values showed the following relationships: 1) May 1984 total catch= (4.95+~2.71) x (May 1983 total catch). 2) May 1984 perch catch= (5.63 ~ 3.60) x (May 1983 perch catch). 3) May 1984 angler hours= (4.58 ~1.91) x (May 1983 angler hours). 4) May 1984 angler trips= (5.68 ~ 2.79) x (May 1983 angler trips). The catch rate comparisons f or May 1983 to May 1984, f or total f ish and yellow perch are: 6 neither catch rate could be shown to be significantly dif ferent between the 2 years for the month of May. Sim-ilar statistics for the fishing pressure (angler hours and angler trips), the estimated total f ish caught, and the estimated yellow perch caught (May 1984+ May 1983) all had a ratio value significantly higher than 1.00. Therefore, these statistics were higher in 1984 than 1983. These figures demonstrate the extreme year-to-year variability of certain estimates that can occur within a fishery and the danger of extrapolating any single year's data over several years. This variability is most likely due to year class strength of yellow perch in the fishery. Another year -to -year comparison could be made with the 1984 Arenac County data using similar ice fishing data collected from 1974 to 1978 (Weber 1985). The three statistics compared were the number of perch caught, the hours spent fishing, and the number of fishing trips made by anglers. The 1977-78 ice fishing season had the most perch caught (501,806~+43,851) and the highest numbers of angler hours (161,749~ 10,708) and angler trips (48,749~+4,,171). The 1975-1976 ice fishing season had the lowest estimated perch catch (41,583~+26,988) and the 1976-1977 ice fishing season had the lowest number of angler hours (47,872+16,839) and angler trips (6,539 ~1,858). These statistics are partly influenced annually again by the year class strength of yellow perch and are strongly influenced by the length of the season or by the length of time ice covers the bay (Ryckman and Lockwood 1985). These data are summarized monthly in Table 13. Total fishing pressure, total catch of all fish, and total yellow perch caught appear to be dependent on the number of yellow perch available to the anglers. This most likely is related to year class strength, as reflected in the recruitment of 6- to 8-inch perch in the fishery. These sizes make up 83.8% of the yellow perch caught (Table 4). Catch rates of total fish and yellow perch appear to be consistent-from month to month. This suggests anglers will fish Saginaw Bay as long as yellow perch are available to be caught and will not fish the Bay when yellow perch are not available or catchable. Fishing pressure estimates for the four -county area surveyed were fairly precise. Two standard errors of the estimated angler hours, divided by the estimate were equal to 6.83%. The same statistic for angler trips was 8.44%. Estimates of catch rates for yellow perch and total fish were not as precise as the pressure estimates. Two standard errors of the catch per hour, divided by the estimate of catch peer hour, were 15.09% for yellow perch and 14.63% for 7 RECOMMENDATIONS Future surveys of Saginaw Bay should probably be done for at least 2 and preferably 3 consecutive years to better determine the between - year variation of fishing pressure and catch. Census clerks working on Saginaw Bay should spend at least 8 hours per work day collecting interviews to improve the estimates of catch rates and catch. Since there seems to be a strong linear relationship between estimated angler hours per month and the number of yellow perch caught per month (Fig. 2), this relationship should be tested in any future surveys at Saginaw Bay. If this relationship remains fairly constant from year to year, it may be possible to estimate the yellow perch catch more economically by only making angler pressure counts. This method could not be used to make catch estimates of other fish species, however.
