Available in PDF, EPUB and Kindle. Book excerpt: Anadromous runs of Atlantic salmon have been restored to the Connecticut, Merrimack, Pawcatuck, Penobscot and St. Croix rivers in New England by the stocking of more than 8 million smolts since 1948. Fish-breeding methods have been developed that minimize inbreeding and domestication and enhance natural selection. Methods are available to advance the maturation of brood stock, control the sex of production lots, and store gametes. Current hatchery practices emphasize the use of sea-run brood stock trapped upon return to the rivers and a limited number of captive brood stock and rejuvenated kelts. Fish are allowed to mature naturally, after which they are spawned and incubated artificially. Generally, 1-year smolts are produced, and excess fish are stocked as fry in headwater streams. Smolts are stocked during periods of rising water in spring. Self-release pools are planned that enable smolts to choose the emigration time. Culturists keep good records that permit evaluation of the performance of strains and the effects of breeding practices. As Atlantic salmon populations expand, culturists must use sound breeding methods that enhance biotic potential while maintaining genetic diversity and protecting unique gene pools.

Available in PDF, EPUB and Kindle. Book excerpt: Published in Cooperation with THE WORLD AQUACULTURE SOCIETY Aquaculture loses millions of dollars in revenue annually due to aquatic animal diseases. Disease outbreaks continue to threaten profitable and viable aquaculture operations throughout the world. As a result, aquaculture biosecurity programs that address aquatic animal pathogens and diseases have become an important focus for the aquaculture industry. Aquaculture Biosecurity: Prevention, Control, and Eradication of Aquatic Animal Disease provides valuable information that will increase success in combating infectious aquatic disease. Key representatives of international, regional, and national organizations presented their views on this important issue as part of a special session at the 2004 World Aquaculture Society Annual Conference. The chapters of this book cover a wealth of experience from the varied perspectives of these experts on biosecurity, policies, and measures to take the offensive against the spread of diseases in aquatic animals. With contributions from renowned international experts, covering approaches to biosecurity policies and measures currently practiced, Aquaculture Biosecurity: Prevention, Control, and Eradication of Aquatic Animal Disease is a vital reference for all those concerned about protecting aquaculture from impacts of aquatic animal disease.

Download or read book Salmonid Field Protocols Handbook written by David H. Johnson and published by . This book was released on 2007 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first publication to collect, standardize, and recommend a scientifically rigorous set of field protocols for monitoring and assessing salmon and trout populations. Includes five additional techniques that can be used with any of the 13 principle methods to supplement information gathered.Over four dozen fisheries experts throughout the U.S. Pacific Northwest and beyond contributed their time to pick, write, and review the most reliable protocols for enumerating salmonids in the field. Presented in an easy to use format, each of the 18 peer-reviewed protocols covers objectives, sample design, data handling, personnel and operational requirements, and field and office techniques, including survey forms.Standardized monitoring protocols will improve data reliability, maximize opportunities for data sharing and data set comparability, and ultimately improve the ability to assess status and trends. The Handbook will also support consistency in data collection for salmonids at the international level.
