Book Description
Excerpt from Pacific Salmon Fisheries The most valuable commercial fisheries in the world, excepting only the oyster and herring fisheries, are those supported by the salm Ons. Of these the most important by farare the salmon fisheries Of the Pacific coast Of North America, where California, Oregon, Washington, and Alaska, including also British Columbia, possess industries representing millions of dollars of investment and millions of output annually. In Siberia the fishery is increasing in. Impor tance annually as means of transportation become better, while Japan is also becoming a large factor in the salmon markets of the world through her investments in the salmon fisheries of Siberia and, to a lesser extent, through fisheries prosecuted in her own waters.

Book Description
Excerpt from The Salmon Fisheries of the Pacific Coast In most places the flesh is of a deep salmon red, but in certain places, notably southeast Alaska, Bristol Bay, Puget Sound, and British Columbia, many of the fish, the proportion being sometimes as much as one-third of the catch, have white flesh. A few examples have been taken with one side of the body red and the other white, while some are found with mottled flesh. No reasonable explanation of this phenomenon has yet been given.

Book Description
Excerpt from Blood Types in Pacific Salmon One of the most important problems in fishery biology is recognition of races or reproductively isolated subpopulations, of fishes. Since there may be little or no interbreeding or recruitment between such populations, successful regulation or management of fishery resources must be con ducted in such a way as to recognize their independence.

Book Description
Excerpt from The Salmon There are at least two respects in which the subject of Salmon is important, and two in which it is interesting. It is important commercially, the salmon fisheries forming ancient and valuable property, a large means of employ ment, and a very considerable supply of food somewhat less important as furnishing an old and keenly - relished sport, the privilege of exercising which has become a sort of property superadded to the value for purely commercial uses. It is interesting as involving some of the strangest facts, the most instructive experiments, and the most perplexing mysteries in natural history; and as having within these few years undergone inves tigation more searching and legislation more vigorous than for centuries before. The subject, too, is especially a British, or British and-lrish one - still more especially a Scottish one. The great majority of countries have by nature been cut off from direct interest and from any kind of power in the matter, and no country has an interest at once so great and so imperilled as our own; for upon few nations has the gift of the king of fish been conferred.

Book Description
Excerpt from Alaska's Fishery Resources, the Pink Salmon Pink salmon have the shortest and simplest life his tory of any Pacific salmon. Because they have a 2-year life cycle and return to their native streams to spawn, two genetically distinct lines occur in each stream. The lines are called even or odd-year on the basis of the year in which the adults spawn. Differences in the num ber and in the size of the fish in the two lines have been the subject of speculation for many years. In some areas, only one line spawns in significant numbers, leaving fish erman with few or no fish in an off year. For example, Although several attempts have been made to trans plant pink salmon to waters outside their natural range, no new important fishery has been established. The United States planted them in rivers in Maine, the Rus sians in tributaries of the Barents and White Seas of northern Europe, and the Canadians in tributaries to Hudson Bay and in rivers in the Maritime Provinces of eastern Canada. None of these efforts resulted in runs that survived more than a few cycles. Although pink salmon do not usually complete their life cycle in fresh water, an accidental release of several hundred fry resulted in a population that perpetuated itself for a few cycles in Lake Superior.

Excerpt from Pacific Salmon: Hatchery Propagation and Its Role in Fishery Management; Circular 24 There are years of too few fish and years of too many fish for the spawning areas available, but with out outside influence, the runs would tend to stabilize themselves. As in the maintenance of all living things, one species lives upon, and is controlled by, other species to pro vide a balance throughout the natu ral environment.

Book Description
The Behavior and Ecology of Pacific Salmon and Trout explains the patterns of mate choice, the competition for nest sites, and the fate of the salmon after their death. It describes the lives of offspring during the months they spend incubating in gravel, growing in fresh water, and migrating out to sea to mature. This thorough, up-to-date survey should be on the shelf of everyone with a professional or personal interest in Pacific salmon and trout. Written in a technically accurate but engaging style, it will appeal to a wide range of readers, including students, anglers, biologists, conservationists, legislators, and armchair naturalists.

Excerpt from Salmon and Salmon Fisheries IF the announcement in the Programme of this day's Con ference means that there is to be an account given of the Salmon and Salmon Fisheries of the United Kingdom, I fear that any information I can furnish will not do justice to the subject; for my knowledge of Salmon and Salmon Fisheries is derived only from my experience as a pro prietor of salmon fisheries in one river in the south of Scotland, viz., the Tweed; and from having had some share in managing the fisheries of the river, and of the sea-coast on each side of its mouth.

Book Description
This study attributes the chronic economic distress of the valuable Pacific salmon industry not only to decline in catch but also to the economic problems of open access ocean fisheries. It analyzes salmon public management programs and proposes alternatives. Originally published in 1969
