BLUEGILL

Very Good

0.1 lbs

6

Little Grassy Lake bluegill abundance in spring 2015, as measured by catch-per-unit-effort, was adequate and similar to the previous year. The proportion of fish larger than 6 inches dropped somewhat compared to the previous year, but still met the goal at 42%. Bluegill larger than 7 inches also dropped to 26% of the sample, however it should be noted that Little Grassy bluegill quality posted a 20-year high in 2014, and 2015 numbers were still excellent. As usual, average bluegill body condition was slightly lower than the desirable range.

LARGEMOUTH BASS

Very Good

1.6 lbs

15

The Little Grassy Lake largemouth bass population is generally well balanced and contains fish ranging in size from fingerlings to trophies. In 2015, bass abundance was high, nearly twice that of the management goal. Bass quality, as measured by length, was easily within the management plan goal range with 60% larger than 12 inches and 16% over 15 inches. As is often the case in clear, infertile lakes, bass body condition (measured by relative weight) remained somewhat lower than the goal, but the 2015 sample included bass over 6 pounds. Threadfin shad stockings are part of an ongoing plan for improving bass body condition, and annual spring stockings will be continued as long as these fish are available.

REDEAR SUNFISH

Very Good

0.1 lbs

6

Little Grassy Lake redear abundance in the spring 2015 sample was lower than that of bluegill, as usual and as similar to the previous year. Although redear quality based on length decreased somewhat, it continued to be very impressive, with 67% of fish over 7 inches, 61% larger than 8 inches, and 15% exceeding 9 inches in length. Similar to other species in this relatively infertile water body, Little Grassy redear body condition was slightly lower than the goal range.
