XX.—Some Observations on the Charr (Salmo umbla), relating chiefly to its Generation and Early Stage of Life
Published online by Cambridge University Press: 17 January 2013
Extract
The natural history of the Charr, especially as regards its generation and the early period of its life, is admitted to be very defective, partly, no doubt, arising from the peculiar habits of the fish withdrawing it from observation, and in part, and more, to the circumstance that it is comparatively of rare occurrence, being found only in a limited number of the deepest lakes of this country, and, with few exceptions, seldom taken by the angler, and consequently a good deal removed from the notice of the naturalist.
Residing for several years in the neighbourhood of Windermere,—a lake in which this fish, though decreasing in number, is still pretty abundant,—I endeavoured to collect information respecting its breeding, the time required for the hatching of its ova, and the peculiarities of the young fish after its exclusion, but in a great measure in vain. The fishermen of the lake were acquainted with its spawning season and the spawning localities; but none of them had ever seen a young charr after its quitting the egg, nor till it had attained a notable size.

page 324 note * I am disposed to think that the breeding-time of the charr in Windermere is even less limited than is stated above, having found in the latter end of February individuals with the testes nearly of their full size, and this not in large fish; and others with ovaries containing eggs varying in size from a mustard to a millet seed. These fish were all from the lake; I have never heard of one being taken or seen in the Brathay (a river flowing into the lake, to be mentioned hereafter) after December.

page 332 note * The charr of the Lake District, though occasionally taken with the artificial fly and minnow, like the trout, on the whole, I believe, may be considered a more delicate feeder, and, in consequence, of superior quality for the table; its organization is in accordance with this, viz., its smaller teeth, and smaller stomach and intestines. The charr of Upper Austria is said to have a thick stomach, approaching in its character to that of the Gillaroo trout. (See Salmonia, p. 55, ed. 4th.) In most instances that I have examined this organ in the charr of the Lake District, I have found it as thin, and often even thinner in its coats than that of the trout inhabiting the same water.
