Round whitefish eggs are collected from broodstock in Little Green Pond, and incubated at the hatchery in jars.
Aging round whitefish (Prosopium cylindraceum) of the Leaf River, Ungava, Quebec, by otoliths.
Species-specific restrictions are not possible because humpback whitefish and least cisco, as well as round whitefish (Prosopium tylindraceum) and the occasional broad whitefish (Coregonus nasus), often occupy the same areas in the river concurrently, and it is difficult to distinguish among species while spear fishing.
Resident fishes in the river include round whitefish, Arctic grayling (Thvmallus arcticus), northern pike (Esox Lucius), burbot (Lola iota), longnose sucker (Catostotmts catosiomus), slimy sculpin (Cottus cognates), and Alaskan brook lamprey (Lethenteron alaskense).
SPECIES RAISED: Walleye; also some rare or threatened fishes, such as round whitefish, and lake sturgeon.

Classified as a state endangered species since 1983, the native round whitefish (or frost fish) had once been found in more than 80 Adirondack lakes, but by 2006 was only known to exist in seven of these historical waters.
Officially known as round whitefish (Prosopium cylindraceum), these medium-size fish are known to many as "frost fish" because they spawn late in the year (November and December), sometimes under the ice.
We analyzed abundance indices, as logetransformed catch-per-unit-effort (CPUE), of four marine species (arctic cod, Boreogadus saida; fourhorn sculpin, Myoxocephalus quadricornis; arctic flounder, Pleuronectes glacialis; saffron cod, Eleginus gracilis); two freshwater species (round whitefish, Prosopium cylindraceum; arctic grayling, Thymallus arcticus); and the anadromous rainbow smelt, Osmerus mordax, to determine whether there were increases in the abundances of marine species and declines in anadromous and freshwater species.
This group includes the anadromous rainbow smelt (Osmerus mordax); freshwater species, arctic grayling (Thymallus arcticus) and round whitefish (Prosopium cylindraceum); and marine species, arctic cod (Boreogadus saida), saffron cod (Eleginus gracilis), fourhorn sculpin (Myoxocephalus quadricornis), and arctic flounder (Pleuronectes glacialis).
Round whitefish and brook trout prospered in the historic conditions of low diversity, but declined with the introductions and resulting competition from nonnatives.
Restoring certain target species, such as brook trout or round whitefish, also maintains their presence in the region.
