|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.|
Sabin Lake (69-0429) better known as Embarrass Mine Pit is a designated stream trout lake located two miles east of Biwabik. The access is via a steep concrete ramp in the middle of the lakes north shore. It is a 156 acre clear water lake with a maximum depth of 465 feet. This pit was originally operated from 1943 to 1964 as an iron ore mine. After abandonment, the mine was allowed to fill with water. There are no inlets or outlets and the mine walls are generally very steep with some sloughing gravel areas.
On June 6, 2013 the water temperature ranged from 62 F at the surface to 38 F at 100 feet. Oxygen levels were good throughout the entire measured water column. This population assessment consisted of three shallow gillnet, three deep gillnet, and no trapnet sets.
From 1984 to 2010 various sizes and strains of rainbow trout, brook trout, lake trout, and even Atlantic salmon were stocked. Lake trout adults were only stocked in 1984 and 1985. After 1985, only rainbow trout and brook trout have been stocked. From 1990 to 2010, rainbows and brookies were stocked in alternating years.
The shallow gillnet catch rate for all fish combined was 16.7 fish/net which is slightly higher than the historical average for the lake. The deep gillnet catch rate for all fish combined was 4.0 fish/net which is below the historical average for the lake. Only four fish species were sampled: lake trout, white sucker, bluegill, and a chub species.
A total of 40 lake trout were sampled between all the nets. A catch rate of 9.7 fish/net in the shallow sets is the highest catch on record. The catch rate for deep nets was 3.7 fish/net which is just below the average of 4.1 fish/net. Average lengths were 16.0 inches for shallow caught fish and 14.0 inches for deep caught fish. Maximum lengths were 20.5 and 20.0 inches respectively. Average weights per fish were 1.4 and 1.0 pounds for shallow and deep caught fish. Ages ranged from 8 to over 15 years with the 2000 and 2005 year classes contributing heavily to the population.
Eighteen white suckers were captured in shallow sets for a catch rate of 6.0 fish/shallow gillnet. This rate is bested only by the 2000 survey which had 12.7 fish/net. Lengths ranged from 6.0 to 20.5 inches with an average of 12.0 inches. Sizes have remained similar throughout the historical netting.
One bluegill was sampled in the shallow nets and was nearly 9.0 inches long.
