Mcneil and published by Forgotten Books. This book was released on 2018-02-21 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Distribution of Spawning Pink Salmon in Sashin Creek, Southeastern Alaska, and Survival of Their Progeny Although the upper area was highly productive of pink salmon fry, it has had intensive spawning only in years when the density of spawners was high. When the density was low, spawners tended to concentrate in the lower area. The validity of the supposition that only highly productive spawning beds are used when escapements are small is questioned. The observations at Sashin Creek indicate that relatively large escapements help ensure complete use of productive spawning beds.

Manhard and published by . This book was released on 2016 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pacific salmon form distinct, locally adapted populations because of the spatial and temporal precision with which they home to their natal streams. Local adaptation is recognized as an important component underlying the productivity and sustainability of salmonid populations, yet there remains uncertainty of the scale at which it occurs. This uncertainty was addressed by analysis of demographic, genetic, and experimental data collected from seasonally structured brood lines of Pink Salmon that spawn in Auke Creek, Alaska. An extensive background of research on this system has indicated that the timing of the adult and juvenile migrations is closely aligned with fitness and productivity in this stream; this background provided a framework for synthesizing the results of the analyses to address these questions: (1) What ecological factors influence productivity of the freshwater and marine life history stages; (2) Do these factors suggest a mechanism for evolution of migration time; (3) What are the consequences of disrupting fine-scale local adaptation of migration time? Freshwater productivity appeared to be influenced primarily by competition for spawning habitat, rather than variability in environmental conditions. Marine productivity, conversely, was associated with physical processes that influence survival of juveniles in the nearshore environment. Consistent with these findings, genetic evolution of earlier migration time, which was observed in both adults and juveniles over two generations, appeared to be driven by earlier vernal warming of the nearshore environment. Despite these environmental changes and resulting selection against late migrating fish, recruitment to Auke Creek has remained stable, thereby indicating that seasonal structure of migration time has supported sustained productivity in a changing climate. Experimental relaxation of natural barriers to gene flow that maintain the seasonal structure resulted in intermediate adult migration times in two generations of hybrid fish. These patterns were consistent with an additive genetic basis for migration time and suggest that ecological outbreeding depression is a post-zygotic mechanism that maintains adaptive variation of migration time in Auke Creek. Collectively, these results provide evidence that fine-scale local adaptation can enhance productivity of salmonid populations while providing resilience to climate change.
Book Synopsis Preliminary Report on Genetic Diversity of Southern Southeast Alaska Pink Salmon Populations by : Alaska Fisheries Science Center Nationa
Download or read book Preliminary Report on Genetic Diversity of Southern Southeast Alaska Pink Salmon Populations written by Alaska Fisheries Science Center Nationa and published by BiblioGov. This book was released on 2013-06 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 1970's the National Oceanic and Atmospheric Administration (NOAA) was made to manage our oceanic and atmospheric resources. The Alaska Fisheries Science Center is the research branch for marine life and coastal oceans off parts of the U.S. west coast and Alaska. This includes the Eastern Bering Sea where some the worlds most important commercial fishing takes place. Their mission is to develop and maintain scientific exploration to help understand and manage that region's environment. Over the years there have been many reports published which discuss their findings; this is one of them.

Available in PDF, EPUB and Kindle. Book excerpt: Cruise no. 126 of the Albatross III was planned and conducted to gather information about the distribution of fishes across the Continental Shelf from Nantucket Shoals to Cape Hatteras during the late winter period when water temperatures generally are at their minimum. The shelf here has a general hydrographic similarity from north to south, well described by Bigelow (1933), that makes it a particularly worthwhile area in which to study the relation of fish distribution to water temperature, depth, and other factors of the environment. Since the fish of this portion of the shelf support several different, relatively important food and industrial fisheries, as well as an intensive marine sport fishery. Cruise no. 126 served to provide data valuable to several research programs.
