Part 24

Body, slim, scales very small; back, blue and sides silvery white. Profusely spotted on the after part of the back, with large oval spots on the tail. Gills, 11 to 13.

THE DOG SALMON

(Oncorhynchus keta)

The dog salmon rarely exceeds ten pounds in weight. Its range is from the Sacramento river north, and its spawning-grounds the small streams up which it never extends any great distance from the salt water.

Head, quite pike-like in shape and therefore much longer and slimmer than the chinook. Back, dirty brown, with the sides of much the same color, but of a lighter tint; fins, very dark; very few distinct spots, with those showing very small; gills, 13 or 14.

=Tackle and Lure=--The Pacific salmon are only caught by trolling. They will take a spoon, or any live bait. The most successful lure, however, is a sardine, or other small fish of six to eight inches in length. Pass the hook through both eyes, take a half hitch around the head, insert the point of the hook in the gill and by bending the fish in the shape of the hook bring the point out about an inch and a half or two inches from the tail. This allows the fish to remain curved, and gives it a revolving motion while trolling, resembling a live, though disabled fish.

A salmon rod should consist of a butt 14 to 16 inches in length, with a hand piece in front of the reel; tip, 6 feet long and not to weigh more than 7 ounces; line not to exceed standard 12-thread. With fishes weighing from 40 pounds and upward, 300 feet of line can be used to advantage.

THE RAINBOW TROUT

(Salmo irideus)

There are at least four distinct species of trout; that is, trout proper and chars, now common to the coast. One of these, the Eastern brook trout, is the result of artificial hatching and distribution. These, as well as the rainbow, and to lesser extent the cutthroat, have been so widely distributed by the state fish commission and private hatcheries that to attempt to give the present habitat of the several species would be sure to result in many errors which might be confounding. The Eastern brook trout has taken kindly to our waters and seem to be doing well in all suitable streams. Several other foreign species of trout have been introduced into our waters as well as these, among which are the Loch Leven, the German brown trout and the Mackinaw, but the success of their acclimatization has yet to be fully determined, though the Loch Leven and German brown seem to be doing well in the higher streams.

The Eastern brook trout and the native species, known as dolly varden, are chars and belong to the genus =Salvelinus=, but the rainbow and the cutthroat are true trout belonging to the genus =Salmo=. The rainbow and the cutthroat present a variety of forms in different localities and these have been given separate specific names by the naturalist. With many of these species(?) the only difference seems to be too slight to entitle them to specific or even sub-specific separation; the variation being no more than that found in the color and markings of the same fishes in the same stream, caused by the depth of the water, the food, or other local conditions.

The rainbow trout is now a resident, either through natural or artificial distribution, of nearly all the streams of the Coast from Washington to Lower California. They vary in size, color and number of scales in different localities and have been given distinct specific names in the various sections, those of the Coast streams of California being used as the typical form. These several varieties, even in their natural condition, showed very little, if any positive line of demarkation, but since the establishment of the many hatcheries on the Coast and the wide distribution of the fry hatched from the spawn of the rainbow of the Sacramento and its tributaries, of the steelhead of the Eel river, and of the typical form of the Coast streams, there seems but one course now left, and that is to group them all as one species under the original name of rainbow.

The rainbow is a very handsome trout, varying in size from adults of but a few inches in the smaller Coast streams, to 25 and 30 inches long in the larger rivers and lakes. Its dark spotted back and silvery sides with the rich metallic colors of the rainbow streak gives it a coloration that is at once brilliant and pleasing. As a game fish it has no superior, if indeed an equal. It takes the fly with a rush, often leaping out of the water to seize it as it is descending. Then it fights with a determination, often breaking three or four feet into the air, shaking its head to free the hook like a terrier shakes a rat. It seldom sounds and never sulks. The rainbow trout goes to the sea at varying ages, the same as all other trout that can get there without passing through long stretches of warm and sluggish water. In the salt water it attains a greater size, changes its color in accordance with the length of time it has been there, but on returning again to the stream it soon assumes its original plan of coloring.

Head, about one-fourth of the whole length from the snout to the base of the caudal fin, varying much with age and size. Generally the greatest depth is about one fourth of the length of the fish, but this also varies very much with the character of the waters it inhabits. In rapid running streams the fish are always slimmer than in more sluggish ones. I have known them 20 inches or more in length, when confined in large reservoirs, to become so heavy that they would weigh one pound to every two inches in length. The lateral line, or rainbow varies, in intensity of color, but always showing in varying shades of red, pink, and sometimes blue of a metallic luster. The vertical black blotches seen on the sides are the marks of immature fish.

The snout of the rainbow is considerably more rounding than that of the salmon, and the head larger in proportion. The eye also is much larger and fuller. The shape and position of the fins are almost identical with those of the salmon, but a little larger in proportion to the size of the fish. The tail, however, varies considerably, being more rounded, and showing only a slight indentation in the center.

THE GOLDEN TROUT

(Salmo irideus agua bonita)

If there is any variety of the rainbow trout found on the Coast that is entitled to a sub-specific name it is the golden trout of Mt. Whitney. They were originally found in only a short portion of two little streams fed by the snows of Mt. Whitney, and vary but little from each other. In one stream they have been given the name of =Salmo irideus agua bonita=, and in the other that of =Salmo irideus rooseveltii=, after ex-president Roosevelt. They are of a beautiful color with scarlet markings at the base of the fins and with a lateral stripe of bright scarlet blending into a rich orange. One peculiarity of these fish is that the par marks or vertical blotches on the sides of other young fish still show on the adults of these. This form of the rainbow has changed its color through the process of natural selection, caused no doubt, by the color of the rocks in the shallow streams it inhabits. Below on these same streams where the rocks are of a darker color the fish assume the natural color of the rainbow.

The writer is possibly the first white man to ever catch one of the golden trout. They were taken in 1865 with a small piece of the flank of a deer skin slipped over the hook, with the hair clipped to about half an inch in length. No sooner was this improvised fly cast upon the water than it was eagerly seized by one of these beautiful fish. When it was landed the color astonished me, and knowing that it was a trout, I thought it must be a diseased one and threw it back. Making another cast I secured another one as promptly as the first, and it being the same objectionable color and of the same size--about eight inches--I concluded that it was the same fish and this time threw it on the bank. As fast as my deer skin fly would strike the water it would be eagerly seized by one of these game little fellows and all of the same size and color. I was puzzled and called to my companion, who was cooking our supper but a few yards away, to "come and see what was the matter with these fish." Professing some scientific knowledge, he cut one of them open, examined the meat and the intestines and finally pronounced it in a healthy condition, finishing with:

"The coffee is boiling and the bacon is fried; hurry up, and as soon as you get a mess I'll fry them and take all chances."

I soon had a mess for supper and while he was frying them I caught enough for breakfast, for the game little fellows would race for the fly as fast as it struck the water. We ate them with a relish, for we had had nothing but bacon, venison and frying-pan bread for a month. As we found ourselves alive in the morning we increased the prescription to a good alapathic dose for breakfast.

The golden trout are small, rarely reaching a length of more than fifteen inches. The back is olive, sides and belly light orange or golden yellow with a scarlet stripe along the center of the belly and at the base of the pectoral, ventral and anal fins, which are of themselves more or less of a golden color. Tail, olive, grading into orange on the lower part. Few spots in front of the dorsal fin but abundant behind it.

While the rainbow trout of the Coast have been given several sub-specific names, such as =masoni= for the Coast streams of Oregon and Washington, =shasta= and =stonei= for those of the upper Sacramento basin, and =gilberti= for those of Kern river, there seems to be so very little reason for this distinction beyond the usual variations of color in all trout, spots and size with the changing conditions of water and feed, that I shall make no mention of the very slight variations upon which the ichthyologist has based the claim to a sub-specific nomenclature.

THE STEELHEAD TROUT

(Salmo rivularis)

The history of the so-called steelhead trout and the efforts to class these sea-run fishes as a species separate from the rainbow and the cutthroat, is interesting, if not amusing. No one questioned that they were other than the sea-run of the rainbow or the cutthroat, according to the locality, until Dr. Richardson, mistaking a young blue-back salmon for a so-called steelhead gave it the scientific name of =Salmo gairdneri=, and the description of this young salmon was recognized as that of the steelhead for years, and under this name it appears in the statutes of California, with a separate season for its protection. In other words the =Salmo gairdneri= of the laws of California is a young blue-back salmon and not a sea-run trout of any kind. Recently Dr. Ayers to correct the mistake, examined a fish taken from the Sacramento river and said to be a steelhead, gave it the name of =Salmo rivularis=, and this now stands as the scientific name of the so-called steelhead. Dr. Jordan, in an article recently published in the Pacific Monthly, says: "There has been much discussion as to whether the steelhead is a species really distinct from the rainbow trout, and on this subject the writer (Jordan) has at different times held different opinions."

If one authority bases his reasons for a belief in a specific difference between the rainbow and the steelhead on the fact that he did find a difference between a blue-back salmon and a rainbow, and another authority finds so little difference that he holds different opinions at different times, can there be any wonder that the practical angler, who catches these sea-run fish at the mouths of our rivers in every stage of transition, or gradation, if you please, from the typical rainbow to the Simon pure steelhead, refuses to believe that there is a specific difference?

Then again, Messrs. Jordan and Evermann in bulletin 47 of the United States National Museum, "The Fishes of North and Middle America," say: "In the lower course of the Columbia they (the steelhead) are entirely distinct from the cutthroat or clarki series, and no one would question the validity of the two species. In the lower Snake river and other waters east of the Cascade range, the two forms or species are indistinguishable, being either undifferentiated or else inextricably mixed."
