Available in PDF, EPUB and Kindle. Book excerpt: Criteria for the design and construction of a prototype streamside incubator for Pacific salmon (Oncorhynchus) eggs and alevins are described. Operation of the prototype and methods of transporting freshly spawned salmon eggs from distant sources are reported. Effects of water velocity, stocking density, and substrate type on the growth, development, survival, and behavior of Pacific salmon embryos, alevins, and fry were studied. The results suggest that the optimum conditions result from low stocking density of about one layer of fertilized eggs, water velocity of 54 to 220 cm/hr. and a smooth cobble substrate. The prototype incubator was tested with about 500, 000 salmon eggs in 1968-69. Due to some serious mechanical problems and poor water circulation in the hatchery tanks, mortalities exceeded the fry production for the first year of operation. Several problems were identified and design improvements suggested. A method was developed for transporting live salmon eggs unfertilized by packing the eggs and milt in separate containers. By maintaining temperatures of 6°c and effecting fertilization after 20 hours in storage, very high (> 90%) fertility was obtained. A practical application of the method was demonstrated with 150,000 pink salmon eggs transported from southeastern Alaska to Oregon.

Book excerpt: This field guide describes procedures for operating an Atlantic salmon (Salmo salar) enhancement project in which incubation of eggs is required to assure a juvenile salmon supply for stocking purposes. Much of this manual described activities and information gathering relating to the egg incubation aspects of an enhancement project. Use of the deep-substrate incubator is advocated as an effective means to secure swim-up fry. Procedures described in this manual include: brood stock collection, holding, stripping ahd fertilization of eggs, incubator design, preparation, loading and operation; and fry enumation and evaluation of developmental index.

Book excerpt: Pacific salmon are an important biological and economic resource of countries of the North Pacific rim. They are also a unique group of fish possessing unusually complex life histories. There are seven species of Pacific salmon, five occurring on both the North American and Asian continents (sockeye, pink, chum, chinook, and coho) and two (masu and amago) only in Asia. The life cycle of the Pacific salmon begins in the autumn when the adult female deposits eggs that are fertilized in gravel beds in rivers or lakes. The young emerge from the gravel the following spring and will either migrate immediately to salt water or spend one or more years in a river or lake before migrating. Migrations in the ocean are extensive during the feeding and growing phase, covering thousands of kilometres. After one or more years the maturing adults find their way back to their home river, returning to their ancestral breeding grounds to spawn. They die after spawning and the eggs in the gravel signify a new cycle. Upon this theme Pacific salmon have developed many variations, both between as well as within species. Pacific Salmon Life Histories provides detailed descriptions of the different life phases through which each of the seven species passes. Each chapter is written by a scientist who has spent years studying and observing a particular species of salmon. Some of the topics covered are geographic distribution, transplants, freshwater life, ocean life, development, growth, feeding, diet, migration, and spawning behaviour. The text is richly supplemented by numerous maps, illustrations, colour plates, and tables and there is a detailed general index, as well as a useful geographical index.
