Information on Fish in Sligo, copied verbatim from email, Douglas Redmond, Aquatic Ecologist, Park and Planning, to Sally Gagne, Feb. 26, 2000
1990 - 17 species of fish stocked in Wheaton Branch
1992 - 5 species of fish stocked in Wheaton Branch (more individuals of some of the species stocked in 1990)
1994 - 19 species of fish stocked in Wheaton Branch, Flora Lane Tributary, and main stem of Sligo Creek (including 6 species not previously stocked)
1998 - 2 species of fish stocked in the main stem of Sligo Creek (more individuals of species previously stocked)
A total of 23 fish species were stocked, but very few individuals of some species.
Surveys within the last three years (1997-1999) found 17 species of fish. Some of these were very scarce, limited in distribution, or recently stocked. At this point I feel that there are eleven species of fish with stable populations in Sligo Creek and its tributaries:
| American eel | Goldfish | Golden shiner |
| Roseyside dace | Creek chub | Blacknose dace |
| Longnose dace | White sucker | Green sunfish |
| Bluegill | Tessellated darter |
The above species, which differ slightly from those of the COG list shown in the table at the top of this page, are pictured in the Fish Gallery.
Blacknose dace, creek chub, and goldfish were the three species that we had present in Sligo Creek prior to restoration efforts.
American eels migrate between fresh and salt water and are able to get past barriers which would block the movement of most species.
Green sunfish were not stocked, but may have come from ponds in the area; the same may be true of golden shiners, which were stocked, but in very low numbers.
The other five species (rosyside dace, longnose dace, white sucker, bluegill, and tessellated darter) were stocked in significant numbers. All of these species are now spawning in Sligo Creek (except eels which spawn in the ocean).
Further surveys may indicate additional species that have established stable populations.
