Fish Stocking Activity

Fish Stocked by Species for the Last Ten Years

Year Species Size Number Pounds
2013 Walleye fry 2,900,000 29.0

Stocking Notes
1 - indicates fish purchased and stocked by private citizens and sporting groups.
2 - indicates fish purchased by the DNR for stocking.

Stocking Fish Sizes
Fry - Newly hatched fish that are ready to be stocked usually called "swim-ups". Walleye fry are 1/3 of an inch or around 8 mm.
Fingerling - Fingerlings are one to six months old and can range from a size of one to twelve inches depending on the species. Walleye fingerlings range from three to eight inches each fall.
Yearling - Yearling fish are at least one year old. A one-year-old fish can range from three to twenty inches depending on the species. Walleye yearlings average from six to twelve inches.
Adult - Adult fish are fish that have reached maturity. Depending on the species, maturity can be reached at two years of age. Walleye reach maturity between the ages of four and six years.

Fish Consumption Guidelines

Status of the Fishery (as of 08/02/2010)

Fish Lake Reservoir Lake is a 3,071 acre lake located near Duluth, Minnesota with 75% (2,303 acres) littoral area and a maximum depth of 36 feet. Minnesota Power owns and operates a public access on the north side of the lake located at the end of Township Road #285. The Minnesota DNR also operates a public access located off on the far west section of the lake off County Road #15. Fish was last surveyed in 2005. Fish was surveyed during the summer of 2010 to update information about fish populations.

Walleye abundance of 5.7 per gillnet lift was down from 2005 (8.8) and but was still average compared to other Minnesota lakes of similar type. The walleye abundance for 2010 was the lowest recorded of 11 investigations dating back to 1954. Walleye average length was 15.2 inches and growth was average compared to other Minnesota lakes of similar type. This represents a shift in growth patterns from what has historically been below average growth. All year-classes from 1995 through 2009 were represented in the sample, except 1996 and 2000. The 2005 and 2006 year-classes were strong, contributing to 63% of the overall catch.

The last several years of fall young-of-the-year (YOY) walleye electrofishing, combined with the results of this assessment suggest that natural walleye recruitment in Fish Reservoir is currently in decline. The decline in walleye recruitment is not fully understood but is hypothesized to be a result of increasing bass and bluegill populations.

Northern pike abundance of 4.3 per gillnet lift was the same as 2005 and above average compared to other Minnesota lakes of similar type. Average length was 19.5 inches and growth was average compared to other Duluth Area lakes. All year-classes from 2002 to 2008 were represented.

Black crappie abundance of 6.9 per trapnet lift was up from 2005 (2.2) and was above average when compared to other Minnesota lakes of similar type. Black crappie mean length was 9.3 inches and growth was average compared to other Duluth Area lakes. Thirty-three percent of the black crappies captured in trapnets were greater than 10 inches in length. All year-classes from 2002 to 2009 were represented.

Bluegill abundance of 13.5 per trapnet lift was up from 2005 (3.5) and was above average when compared to other Minnesota lakes of similar type. Average length of sampled bluegills was 6.7 inches and growth was average compared to other Duluth Area lakes. All year-classes from 2000 to 2008 were represented.

A total of 64 largemouth bass were sampled with electrofishing equipment. The catch rate of largemouth bass was 43.0 fish per hour of electrofishing. The 2005 largemouth bass electrofishing catch rate was 6.4 fish per hour. Largemouth bass average length was 13.5 inches and growth was fast compared to other Duluth Area lakes. All year-classes from 2002 through 2008 were represented in the sample, with strong 2004 and 2006 year-classes.

Yellow perch abundance of 11.1 per gillnet lift was down from 2005 (13.0) and was above average compared to other Minnesota lakes of similar type. Average length of perch was 6.6 inches. Age and growth of yellow perch was not evaluated for this investigation.

Other fish species sampled included pumpkinseed, rock bass, white sucker, channel catfish and hybrid sunfish.
