This book was released on 2019 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forage fish are key trophic links in coastal ecosystems, transferring energy from lower to higher trophic levels. In the Pacific Northwest, herring are one of the most abundant forage fish species and are prey for a wide variety or organisms. Additionally, human inhabitants of the region have used herring as a food resource for millennia, and archaeological research has demonstrated that herring bones are among the most abundant fish remains unearthed from ancient village sites. Given the importance of herring to the coastal ecosystem and human livelihoods, there is considerable interest in sustainably managing the fisheries which target this species. However, management is complicated by limited knowledge of herring population structure and a lack of long-term temporal data on population diversity. In this dissertation, I (i) develop a laboratory protocol to remove intraspecific contamination from tissues that is compatible with restriction site-associated sequencing, (ii) investigate the mechanisms driving genetic differentiation between herring populations, using genomic data collected from wild spawning aggregations, and (iii) quantify the relative contributions of genetically distinct herring populations to food supplies over the last millennium, using ancient DNA extracted from herring bones.

This book was released on 2021-01-31 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herring are vital to the productivity and health of marine systems, and socio-ecologically Pacific herring (Clupea pallasii) is one of the most important fish species in the Northern Hemisphere. Human dependence on herring has evolved for millennia through interactions with key spawning areas—but humans have also significantly impacted the species’ distribution and abundance. Combining ethnological, historical, archaeological, and political perspectives with comparative reference to other North Pacific cultures, Herring and People of the North Pacific traces fishery development in Southeast Alaska from precontact Indigenous relationships with herring to postcontact focus on herring products. Revealing new findings about current herring stocks as well as the fish’s significance to the conservation of intraspecies biodiversity, the book explores the role of traditional local knowledge, in combination with archeological, historical, and biological data, in both understanding marine ecology and restoring herring to their former abundance.

Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a representative sample of contributions to the 41st European Marine Biology Symposium held in September 2005 in Cork, Ireland. The theme of the symposium was ‘Challenges to Marine Ecosystems’ and this was divided into four sub themes; Genetics, Marine Protected Areas, Global Climate Change and Marine Ecosystems, Sustainable Fisheries and Agriculture. The world’s marine ecosystems face multiple challenges, some natural, but many resulting from humankind’s activities. Global climate change, driven by influences of energy usage and industrial practices, is a reality now accepted by most of the world’s scientists, media and political establishments. Warming seas and rising sea levels are regarded as threats, while visionaries consider deep ocean carbon disposal as a technological opportunity. Exploitation of the seas continues apace, with repeated concerns over the impact of over-fishing, plus reservations about the environmental effects of marine aquaculture. We need to understand how resilient organisms and ecosystems are to these challenges, while responding by protecting biologically-meaningful areas of the oceans. The subthemes of the 41st European Marine Biology Symposium address all of these matters.
Download or read book The Diversity of Fishes written by Gene Helfman and published by John Wiley & Sons. This book was released on 2009-04-03 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of The Diversity of Fishes represents a major revision of the world’s most widely adopted ichthyology textbook. Expanded and updated, the second edition is illustrated throughout with striking color photographs depicting the spectacular evolutionary adaptations of the most ecologically and taxonomically diverse vertebrate group. The text incorporates the latest advances in the biology of fishes, covering taxonomy, anatomy, physiology, biogeography, ecology, and behavior. A new chapter on genetics and molecular ecology of fishes has been added, and conservation is emphasized throughout. Hundreds of new and redrawn illustrations augment readable text, and every chapter has been revised to reflect the discoveries and greater understanding achieved during the past decade. Written by a team of internationally-recognized authorities, the first edition of The Diversity of Fishes was received with enthusiasm and praise, and incorporated into ichthyology and fish biology classes around the globe, at both undergraduate and postgraduate levels. The second edition is a substantial update of an already classic reference and text.

This book was released on 2007 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: "To determine the spawning area contributions of Pacific herring (Clupea pallashii) larvae to nursery bays, otolith chemical analysis was conducted on juvenile fish collected from 1995 to 1997 in Prince William Sound, Alaska. The otolith edge, representing the chemical signature of the known capture location, and the otolith core, representing the unknown spawning ground chemistry, were compared with discriminant function analysis to infer spawning area origin. Chemical signatures of 87Sr/86Sr ,88Sr/48Ca, 24Mg/48Ca, and 138Ba/48Ca were used to identify broad spawning regions from inner and outer PWS that persisted for the three years sampling period despite significant interannual variability in otolith edge chemistry within nursery bays. Age of juvenile Pacific herring, age-0, 1, 2, did not significantly affect the otolith edge signatures; thus, this study is able to conclude from the otolith core chemistry that spawning areas do not contribute equally to nursery bays. This is the first demonstration that otolith chemical signatures can be used to identify the important spawning areas of this commercially important species in the Gulf of Alaska coastal areas"--Leaf iii.
