Status of the Fishery (as of 04/23/2012)

Lake Vermilion is part of the statewide Large Lake Program, an intensive fisheries management program on the 10 largest lakes in Minnesota. The Large Lake Program includes annual population assessments, annual water quality monitoring, and regularly scheduled creel surveys. A variety of sampling gear is used during population assessments to collect the various fish species and life stages. These gear types include gill nets, trap nets, beach seines, and an electrofishing boat. Sampling for each gear type is conducted at the same time and place each year in order to determine population trends for the major species. Data is also collected on length, weight, age, and growth for each of the major species.

The walleye gill net catch in 2012 was 15.4 fish/net, slightly less than the 2011 catch but still above the long-term average for Lake Vermilion. Walleye gill net catches had been below average from 2008 to 2010, due to poor reproduction in 2004, 2005, 2008, and 2009. Improved walleye catches in 2011 and 2012 were due primarily to strong year classes produced in 2007 and 2010. Gillnetted walleye had a mean length of 14.9 inches, the largest average size ever observed on Lake Vermilion. The large average size was due primarily to high numbers of older fish in the gill net catch from strong year classes produced in 2002, 2003, and 2007. The gill net catch of walleye less than 15 inches long was slightly below average, reflecting poor reproduction in 2008 and 2009. The walleye gill net catch was dominated by age 2 fish (2010 year class) and age 5 fish (2007 year class), which composed 27% and 18% of the catch; respectively. Strong year classes of walleye were produced in 2002, 2003, 2006, 2007, and 2010. One year of netting indicates the 2011 year class will also be stronger than average. Weak to fair year classes were produced in 2004, 2005, 2008, and 2009. The special walleye regulation on Lake Vermilion was modified in 2012 to an 18-26 inch protected slot with one fish allowed over 26 inches, and a four-fish bag limit. The previous regulation was a 17-26 inch protected slot with one fish allowed over 26 inches, and a four-fish bag limit. The regulation was modified to allow anglers to harvest some larger fish, while keeping harvest at a safe level.

The gill net catch of northern pike was 0.7 fish/net, slightly below the historic average. Gill net catches of northern pike have historically been fairly stable at a relatively low level. Northern pike are more abundant in some of the shallow bays, however those areas are not sampled during annual assessments. The mean length of northern pike sampled by gill nets was 29.6 inches, well above the historic average. It was the fourth consecutive year pike lengths were above average, reflecting an improved size structure in recent years. The sample size of northern pike in the gill nets was too small (14 fish) for meaningful age and growth analysis. Northern pike reproduction has historically been relatively consistent from year to year without exceptionally weak or strong year classes. A special regulation for northern pike has been in effect since 2003: a 24-36 inch protected slot, with one fish allowed over 36 inches. This regulation is part of a statewide initiative to improve the size structure of pike populations in a number of lakes across the state.

The gill net catch of yellow perch was 23.2 fish/net, slightly below the historic average. Perch gill net catches have been below average since 2007, due to poor reproduction and survival from 2003 to 2009. Gillnetted perch had a mean length of 7.3 inches, which is near the historic average. The gill net catch of perch over 9 inches long was well below average. Perch sampled on East Vermilion were considerably larger than those sampled on West Vermilion, which is consistent with past sampling. The perch catch was dominated by age 2 fish (2010 year class), which composed 59.0% of the catch. The catch of age 2 perch was much higher than average, suggesting 2010 will be a strong year class. The catch of age 1 perch (2011 year class) was also higher than average, while catches of other age classes were all below average. Prior to 2010, the last strong year class of perch was produced in 2002.

The black crappie trap net catch was 1.0 fish/net, slightly below the historic average. Crappie numbers have historically been relatively low on Lake Vermilion, although some areas of West Vermilion have higher numbers of fish. Trapnetted crappie had a mean length of 6.6 inches, well below the historic average. The small average size was due to an unusually high catch of small fish. The trap net catch of crappie over 10 inches long was about average. The crappie catch was dominated by age 1 fish (2011 year class), which composed 48.3% of the catch. It was the highest catch of age 1 crappie since 2006, suggesting 2011 will be strong year class. Other strong year classes of crappie were produced in 2005 and 2006, while weak year classes were produced in 2007, 2008, and 2009.

The trap net catch of bluegill was 19.1 fish/net, well below the historic average. The bluegill catch was much higher on West Vermilion than East Vermilion, reflecting higher bluegill abundance in that lake basin. Trapnetted bluegill had a mean length of 5.7 inches, slightly below the historic average. Bluegill trap net catches have been dominated by smaller fish for several years, with relative low numbers of large fish. The bluegill trap net catch was dominated by age 6 fish (2006 year class), which composed 37.7% of the catch. Strong year classes of bluegill were produced in 2005, 2006, and 2010, while weak year classes were produced in 2004, 2007, and 2008.

Muskellunge population assessments are done every four to six years on Lake Vermilion. Due to the large size of the lake, East Vermilion and West Vermilion are done in different years. A muskie assessment was done on East Vermilion in 2011 and an assessment was done on West Vermilion in 2012. The East Vermilion muskie catch in 2011 was 2.8 fish/net, while the West Vermilion catch in 2012 was 1.1 fish/net. Muskie trap net catches have been gradually increasing since they were introduced as more year classes recruit to the spawning stock. To date, muskie trap net catches have been higher on East Vermilion, while the average size has been larger on West Vermilion. The mean length of trapnetted muskie was 44.9 inches on East Vermilion and 46.2 inches on West Vermilion. About 14% of the muskie sampled on East Vermilion were over 50 inches long, while 30% of the muskie sampled on West Vermilion were over 50 inches long. The largest muskie sampled was 55.6 inches long.

An electrofishing boat is used as the standard sampling gear for smallmouth bass because they are not often caught in standard assessment nets. The smallmouth bass electrofishing catch in 2012 was 36.5 fish/hour, which is near the historic average. Smallmouth bass sampled by electrofishing had a mean length of 11.1 inches, well above the historic average. The large average size was due to good numbers of 12-18 inch bass in the catch. The smallmouth bass catch was dominated by age 2 fish (2010 year class) and age 5 fish (2007 year class), with each year class composing 19.2% of the catch. Strong year classes were produced in 2005 and 2006, while weak year classes were produced in 2008 and 2009. One year of sampling indicates the 2010 year class will likely be stronger than average.

An electrofishing boat is used to sample young-of-the-year walleye in the fall to monitor reproductive success for the year. The fall electrofishing catch of young-of-the-year walleye in 2012 was 216.3 fish/hour, well above the historic average. It was the second consecutive year of high walleye electrofishing catches. The walleye catch was much higher on East Vermilion than West Vermilion. The mean length of young-of-the-year walleye sampled by electrofishing was 5.9 inches, well above the historic average. Growth of young-of-the-year walleye has proven to be a useful indicator of eventual year class strength. Past sampling has shown that large, fast growing young-of-the-year walleye generally produce strong year classes, while small slow growing fish produce poor year classes. Taken together, the 2012 electrofishing catch and growth rate indicate the 2012 year class will likely be stronger than average on East Vermilion and near average on West Vermilion.

There are several invasive species known to be present in Lake Vermilion. Rusty crayfish are very abundant in East Vermilion and are expanding into West Vermilion. Curly-leaf pondweed is now present in Everett's Bay and Stuntz Bay in East Vermilion. Chinese mystery snails were discovered in 2011 in Spring Bay at the far west end of the lake. Purple loosestrife has been found at several sites on the lake, usually in wetland areas adjacent to lake. Heterosporis, a microsporidean fish parasite, has been identified in several walleye and yellow perch from Lake Vermilion, mostly from the west end of the lake. Anglers and boaters should always take preventative measures to avoid moving invasive species to other lakes.
