Tainter, Ph.D. This tiny record of a historical event in our history is what Fish Culture in Yellowstone National Park is all about. Frank H. Tainter’s father, uncles, and grandfather all worked on fish culture details for the former U.S. Bureau of Fisheries in the park during the teens and 1920s. Their experiences provided the inspiration for this book. Frank never worked in the park on the fish culture program. He never would have been able to write this history if his father had not taken many photo snapshots of his experience there. As a retired scientist, Frank tried to include as many references and resource credits as possible so that future readers and users could find more related materials. This book is intended as a sort of “in the trenches” record of a historical event and secondly for its entertainment value.

This book was released on 1967 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: A single objective was sought in writing this report: to summarize, under one cover, significant fishery "milestones" of history, culture, research, and management in Yellowstone. Three fishery "eras" have come to pass in Yellowstone. The earliest extends from John Colter's initial visit and reports in 1806, to the fish cultural era of 1901 to 1957. The third major phase began with US Fish and Wildlife Service fishery research in 1948, lasting until 1962. The present fishery management and research era began in January of 1962, with scope of investigations being expanded annually. This paper is presented in five major sections: 1) history prior to 1901; 2) fish culture; 3) fishery management and regulations; 4) fishery research; and 5) fish stocking.

This book was released on 2016-01-21 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Angling for native fish is an important part of the park's cultural history. Fishing regulations in Yellowstone National Park are structured to strongly support native fish conservation goals. Cutthroat trout are the sole, native trout of the park and were the dominant fish species here prior to Euroamerican settlement. Cutthroat trout, Arctic grayling, mountain whitefish, and other native fishes are important to the ecology of Yellowstone. Introduced nonnative fish cause loss of native fish The number of waters where native fish are found and the abundance of native fish have been substantially reduced, mostly because of impacts by introduced nonnative fish, including brook, brown, lake, and rainbow trout. These nonnative species continue to contribute to the decline in the park's native fish population by competing for food and habitat, preying on native fish, and degrading the genetic integrity of native fish by mating with them and creating hybrids. Loss of native fish impacts park ecosystems Because cutthroat trout and Arctic grayling inhabit relatively shallow waters, many animals depend on them as a food source, especially during spring when the fish spawn in small lake inlets and tributary streams. In many cases, nonnative trout cannot serve as a substitute for cutthroat trout or Arctic grayling because they occupy different habitats. For example, nonnative lake trout live deep in Yellowstone Lake, do not spawn in streams, and are generally inaccessible to many of the park's native fish-eating animals such as bears, otters, and ospreys. A plan to preserve and restore native fish Yellowstone is making a substantial, on-the-ground effort to conserve native fish in several areas. These actions, which are currently focused in the Lamar and Grayling Creek drainages and Yellowstone Lake, are described in the park's native fish conservation plan. Goals of the plan are to reduce the risk of extinction, restore and maintain the ecological role, and create sustainable angling and viewing opportunities for native fish. Anglers assist with native species conservation The Native Trout Conservation Area (see pages 3 and 4) is a large region within the park where native cutthroat trout are actively being harmed by introduced nonnative fish. Angling is one way that the nonnative fish can be selectively removed from an area without damaging the native fishery. Within this area, anglers are strongly encouraged, and in some cases required, to harvest nonnative fish. Along with actions being taken by federal and state biologists and their partners, this harvest will help to save the native fish and the natural ecosystems they support.

Available in PDF, EPUB and Kindle. Book excerpt: Normal 0 The Yellowstone Drainage supports the largest inland population of native Yellowstone Cutthroat Trout on Earth. The Yellowstone Cutthroat Trout is considered a shared resource in Yellowstone Lake: Grizzly Bears, Black Bears, Bald Eagles Golden Eagles, Pelicans, Osprey, Great Blue Herons, Kingfishers, Gulls, Grebes, Terns, Loons, Mergansers, Mink, Otters, Wolves and Coyotes prey upon Yellowstone Cutthroat Trout. In the Yellowstone drainage 200,000-pounds of Yellowstone Cutthroat Trout are eaten each year by these animals and birds. Yellowstone Lake is the largest fresh water lake in the United States above 7,000-feet, it’s altitude is 7,733-feet above sea level. The Yellowstone Lake encompasses 136 square miles, it is 20-miles long, 14-miles wide and has 110-miles of shoreline. Yellowstone Lake is 320-feet deep at its deepest point. The average depth is 139-feet. Yellowstone Cutthroat Trout generally inhabit the upper 60-feet because their food source rarely occurs below that depth. The average surface temperature in August is 60 degrees Fahrenheit; the bottom the temperature never rises above 42 degrees Fahrenheit. The serenity of Yellowstone Lake can suddenly change with afternoon thunderstorms and their accompanying winds. These winds can routinely produce 3-foot waves or larger within minutes on Yellowstone Lake. With water temperatures averaging 41 degrees Fahrenheit you can develop hypothermia quickly if your vessel capsizes. Fishing season in Yellowstone Lake opens June 15th each year, usually! There are 124-tributaries the Yellowstone Cutthroat Trout use for spawning including the largest tributary, the Yellowstone River. These spawning tributaries open July 15th each year, however some remain closed all year. The use of all lead fishing tackle is band; fisherman must use Non-Toxic alternative products. The West Thumb geyser basin area has intense heat in the lake sediments, which indicate a shallow thermal system underlying this more recent caldera. If the lake level should fall just a few feet, an immense steam (hydrothermal) explosion could occur here. Mary Bay and Indian Pond now show evidence of these craters.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Fishes of the Yellowstone National Park: With Description of the Park Waters and Notes on Fishing The present report is a revised and amplified edition of the one published by the Bureau of Fisheries in 1915. The exhaustion of the supply of that document and the continued public demand for information on this subject, together with the availability of new data on the fishes, make this publication desirable. Indigenous Fishes. The native fish life of the park was profoundly affected by the great lava flow which occurred over a large part of the park in Pliocene times. Whatever fishes were then present were necessarily killed, and, with the reestablishment of the watercourses after the cooling of the surface of the lava, fishes in outside waters were to a great extent prevented from reaching the lofty plateau, which comprises most of the area of the park, by the high and steep falls over which the streams leave the lava beds. It thus follows that the native fish fauna of the park is very limited. Except in Yellowstone River and its tributaries practically no fishes occur naturally above the falls, and in the extensive basin of that river the few species that do exist gained access to the region above the falls because of the imperfect watershed separating the Yellowstone and the Snake River basins. The original comparative barrenness of the park in fish life was due entirely to topographical conditions. The physical character of the waters is, in general, highly favorable for fishes, and an examination of the streams and lakes of the park by Prof. Forbes in 1890 disclosed the presence in certain barren waters of an abundant insect and crustacean food well suited for sustaining certain kinds of fishes. The theory that would account for the original absence of fishes in particular park waters as due to the high temperature and chemical constituents of the great volumes of water flowing from the geysers and hot springs is entirely untenable for several reasons: First, native trout abound and flourish in various streams and lakes in close proximity to the outpourings of geysers and hot springs, and, secondly, both native and exotic trouts have been successfully planted in barren waters receiving the discharge of geysers and hot springs. The fishes of natural occurrence in the park represent 10 species, as follows: Longnose sucker, rosyside sucker, chub, silverside minnow, longnose dace, dusky dace. Rocky Mountain whitefish, redthroat trout, Montana grayling, and blob. Of these only the trout and the grayling have generally been recognized as game fishes, although the whitefish might properly be so considered. While these were very abundant in certain waters, the annually increasing numbers of angler-tourists in the park made it desirable to augment the natural supply of game fishes by the introduction into barren waters of selected species of other game fishes.

Available in PDF, EPUB and Kindle. Book excerpt: Normal 0 The Yellowstone River within Yellowstone National Park is the world’s best Yellowstone Cutthroat Trout fishery. The Yellowstone River within the park can be divided into three-distinctive sections. The headwaters of the Yellowstone River begin on the east side of the Continental Divide from the Shoshone Mountain Range of Wyoming. The Yellowstone River flows northerly into Yellowstone Lake, elevation 7,733-feet. Yellowstone Lake is the largest lake at this elevation on the continent. The mid-section of the Yellowstone River, which flows out of Yellowstone Lake downstream to the Upper Falls of the Yellowstone River lies the world renown section of the Yellowstone River where hundreds of people flock to on July 15th “Opening Day” every year. The lower section, below the Lower Falls of the Yellowstone River flows through the Canyon of the Yellowstone downstream to the Yellowstone National Park Boundary, by the town of Gardner, Montana is probably the least fished section of the Yellowstone River. The fishing seasons opens July 15th every year which allows the Yellowstone Cutthroat Trout Brood Stock to spawn and gives the Yellowstone Cutthroat Fry time to emerge from the redds before the wade fishermen can step on them. The headwaters and mid-section of the Yellowstone River are the major spawning areas for the Yellowstone Lake Cutthroat Trout Fishery. The Yellowstone River is a premiere dry fly fishing river with prolific hatches of May Flies: Early Blue-Winged Olive (Baetis tricaudatus), Late Blue-Winged Olive (Baetis parvus), Little Western Blue-Winged Olive (Ephemerella margarita), Western Green Drake (Drunella grandis), Pale Morning Dun (Ephemerella inermis and Ephemerella infrequens) and Small Western Green Drake (Ephemerella flavilinea); Stone Flies: Salmon Fly (Pteronarcys californica), Western Big Golden Stone Fly (Calineuria californica), Western Medium Golden Brown Stone Fly (Isoperla sp.) and Little Yellow Stone Fly (Alloperla pallidula); Caddis: Green Sedge (Ryacophila sp.), Little Tan Short Horn Sedge (Glossosoma sp.), Spotted Sedge (Hydropsyche sp.) and Giant Orange Sedge (Dicosmoecus sp.).

This book was released on 1959 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research to appraise current fish management practices and to develop improved practices was carried on in the Yellowstone National Park portion of the Madison River system from 1953 to 1957. The physical, chemical and biological characteristics of the Firehole, Gibbon and Madison Rivers are described. Experiements designed to test the value of fingerling and adult stocking resulted in the conclusion that fingerling stocking of brown and rainbow trout does not contribute to the fishery substantially and that adult stocking is of greatest value only in the season of stocking. Examination of scales showed that hatchery fish are readily distinguishable from wild fish. There were no differences in growth rates of wild fish in different years for different rates of stocking of hatchery fish. The brown and rainbow trout populatons are not affected adversely by heavy introduction of hatchery fingerlings of each species or of adult rainbows. Brook and brown trout and whitefish are substantially underfished.
