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.

Available in PDF, EPUB and Kindle. Book excerpt: A spawning and incubation channel constructed in 1959 on Abernathy Creek near Longview, Washington, has been used for seasons to incubate fall chinook salmon and chum salmon eggs. Survival of eggs from both species was higher than reported for other channels and controlled-flow projects. Studies included effects of sedimentation, egg planting density, and stage of egg development at planting on survival. In early experiments sediment in the upper sections substantially reduced survival. In later experiments, after the construction of a sand trap and settling chamber, survivals significantly increased.

Available in PDF, EPUB and Kindle. Book excerpt: A set of new predictive models was developed to assist salmonid fish culturists and biologists with a wide range of fish culture problems, including incubation, dissolved oxygen during rearing, and excess total gas pressure. To make use of the models requires a reasonable understanding of mathematics and the use of a scientific calculator or computer, so the models were incorporated into a package of computer programs that would be easy to use. This report describes the use and operation of the programs and presents examples to illustrate the usefulness of each program.

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.
