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 Intertidal Ecology and Life History of Pink Salmon at Olsen Creek, Prince William Sound, Alaska Twelve pink salmon streams in Port Gravina in addition to Olsen Creek were surveyed once a week to check for emigrant tags (fig. A summary of the recovery data is given in table 4. Tagged fish taken in the commercial fishery and those found in the Port Gravina streams were considered emigrants and were subtracted from the total tagged to correct population estimates. The following formula was used to estimate the total spawning population from the ratio of tagged to untagged carcasses.

Excerpt from Pink Salmon, Oncorhynchus Gorbusha: Tagging Experiments in Southeastern Alaska, 1938-42 and 1945 Tagged pink salmon released in Icy Strait moved eastward and then southward in Chatham Strait to Frederick Sound. In Frederick Sound they traveled eastward and then northward. Most of the pink salmon released in lower Chatham Strait during mid July moved into Frederick Sound, and those released in early August moved north into upper Chatham Strait and south into Sumner Strait. Fish released in Frederick Sound in early August distributed themselves throughout Frederick Sound and along Stephens Passage.

Book Description
Excerpt from Stream Catalog of Southeastern Alaska Regulatory District No; 2: Special Scientific Report Fisheries No; 453 The pink salmon of Southeastern Alaska are an important fishery resource. Millions of these fish are captured annually by the commercial fishery during their spawning migration. There are more than 1, 100 known spawning streams, plus hundreds of small, indi vidually unimportant ones, scattered along the 9, 000 coastal miles of Southeastern Alaska. For many years, management and research agencies of the Federal, Territorial and State govern ments, Alaska Salmon canners, and the Fisheries Re search Institute of the University of Washington, have independently conducted stream surveys of the salmon spawning grounds. A vast amount of valuable informa tion has. Been accumulated and has been, in the main, kept on file in the offices of the various organizations. To make full use of all these scattered materials, records from the various souces have been gathered together and methods of stream surveying have been studied on a comparative basis. This information has been consolidated into a standard form which is pre sented here as a stream catalog. This catalog has been compiled under a con tract given to the Fisheries Research Institute by the United States Fish and Wildlife Service. The material contained herein includes 88 major and numerous minor streams of Regulatory District No. 2. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
