Mr. E. A. Preble has the following to say in his report with reference to this fine fish:—

“The Arctic grayling, usually called bluefish in the north, has a very extensive range. It occurs throughout the region from Peace river and Athabaska lake northward and northwestward to Arctic ocean. I can not find that it has been detected in the Athabaska. As it prefers clear streams it is somewhat local in distribution, occurring but seldom in the main rivers, which are usually muddy, but being abundant in many of the clear tributaries and the lakes which they drain. During my explorations I met with the grayling in the lake country between Great Slave and Great Bear lake and at a number of points on the Mackenzie. It was especially abundant in the rapid stream which I descended to MacTavish bay in August, 1903, and I caught many while fishing for trout with a spoon hook. It was common also in Great Bear lake near Fort Franklin a little later, where many were being taken in the whitefish nets.

“The grayling is said to be scarce in the Liard below the mouth of the Nelson, but to be common above that point. It is also found in most of the tributaries of the Mackenzie, several of which have local names referring to its occurrence.

“As an index to the distribution of this interesting fish I have selected the following references: Back recorded it from the mouth of Hoarfrost river, Great Slave lake; from the head of Backs river; and from Lake Pelly on the same stream. Doctor G. M. Dawson reported its capture in upper Peace river, and in the Finlayson, a tributary of the upper Liard. MacFarlane has recorded it from Anderson river.

“I am not aware that the grayling has been recorded from any stream tributary to Hudson bay, except in one instance. Doctor Bell mentions that it was taken in tributaries of the lower Churchill, and that a specimen was identified by Professor Gill as Thymallus signifer. A possible explanation of the occurrence of this fish in the Churchill is suggested by the fact that there is a direct water connection between Churchill river and Athabaska lake. The grayling occurs in Black or Stone river, which flows from Wollaston lake into Athabaska lake. The waters of another outlet of Wollaston lake, Cochrane river, flow by way of Reindeer lake into the Churchill, thus affording to a torrent-loving species like the Arctic grayling a ready means of communication.”

Great Slave Lake Fisheries.

The marvellous productiveness of the fisheries of Great Slave lake and many of the rivers in its vicinity have been time and time again commented upon by travellers.

In the account of his journey in 1772, Samuel Hearne, writing (p. 249) of the fish in Great Slave lake (his Athapapuskow), states:—“The fish that are common in this lake, as well as in most of the other lakes in this country, are pike, trout, perch, marble, tittameg, and methy. The two last are names given by the natives to two species of fish which are found only in this country. Besides these, we also caught another kind of fish, which is said by the northern Indians to be peculiar to this lake; at least none of the same kind have been met with in any other. The body of this fish much resembles a pike in shape, but the scales, which are very large and stiff, are of a beautifully bright silver colour; the mouth is large, and situated like that of a pike, but when open it much resembles that of a sturgeon, and though not provided with any teeth, takes a bait as ravenously as a pike or a trout. The sizes we caught were from two feet long to four feet. Their flesh, though delicately white, is very soft and has so rank a taste, that many of the Indians, unless they are in absolute want, will not eat it. The trout in this lake are of the largest size I ever saw; some that were caught by my companions, could not, I think, be less than thirty-five or forty pounds weight. Pike are also of an incredible size in this extensive water. Here they are seldom molested, and have multitudes of smaller fish to prey upon. If I say that I have seen some of these fish that were upwards of forty pounds weight, I am sure I do not exceed the truth.”

Multitudes of Fish.

Richardson in his “Arctic Searching Expedition” (Vol. 1, p. 160), speaking of Demarais’s fishery on Great Slave lake, writes:—“During the whole summer, in the eddies between the islands of this part of the lake, multitudes of fish may be taken with hooks, and by nets, such as trout, white fish, pike, sucking carp, and inconnu. In spring and autumn wild-fowl may be procured in abundance at several places in the neighbourhood which are their accustomed passes, and the fishery on the north side of Big island seems to be inexhaustible in the winter. With good fishermen, and a proper supply of nets, a large body of men may be wintered here in safety and plenty. In no other part of the Hudson’s Bay Company’s territories, with which I am acquainted can so many people be maintained, with so much certainty, on the resources of the country.”
