Available in PDF, EPUB and Kindle. Book excerpt: Commences with a discussion of biological and statistical considerations involved in designing an effective survey.

Alternative approaches used in each type of survey are reviewed and numerous case histories illustrate successful applications.
Book Synopsis Impacts of Oil Spill Disasters on Marine Habitats and Fisheries in North America by : J. Brian Alford
Download or read book Impacts of Oil Spill Disasters on Marine Habitats and Fisheries in North America written by J. Brian Alford and published by CRC Press. This book was released on 2014-10-29 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: At an increasingly global scale, aquatic scientists are heavily entrenched in understanding the fate of marine ecosystems in the face of human-altered environments. Oil spill disasters, especially large-scale ones like the 2010 Deepwater Horizon tragedy, have left uncertain and indelible marks on marine ecosystems. Impacts of Oil Spill Disasters on Marine Habitats and Fisheries in North America contains independent scientific findings and critical reviews from experts researching the impacts of the Exxon Valdez, Ixtoc I, and Deepwater Horizon oil spills on coastal fishery resources. Comprised of three sections, this seminal work: Details the physiological effects of oil-derived compounds on fishes, presenting results from field and laboratory investigations Addresses the science of assessing the impacts of oil spills and oil response measures on coastal habitats, with an emphasis on salt-marsh ecosystems in the Gulf of Mexico Explores the quantified and potential impacts of oil spills on population and community dynamics of commercial and recreational fishery species Provides newly released results from the 25-year recovery of marine mammals, birds, and fishes following the Exxon Valdez spill Chapters discuss new techniques for collecting and processing blood samples for toxicity testing, new aerial radar techniques for detecting unseen oil on marshes, consequences of oil prevention measures (such as diverting fresh water to estuaries or building sand berms to stop oil) on coastal fishery resources, and non-traditional methods for assessing the herring stock in Prince William Sound, Alaska, USA following the Exxon Valdez disaster.
Book Synopsis Herring Spawn Deposition and Reproductive Impairment by : T. Mark Willette
Download or read book Herring Spawn Deposition and Reproductive Impairment written by T. Mark Willette and published by . This book was released on 1997 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Underwater dive surveys of deposited eggs and acoustic techniques were used to estimate the 1996 adult spawning population of Pacific herring Clupea pallasi in Prince William Sound (PWS). The spawn deposition estimate of the spawning biomass of herring was 25,101 tonnes with a 95% confidence interval ranging from 13,039 to 37,163 tonnes. This project also evaluated the feasibility of using acoustic echointegration techniques to estimate herring biomass immediately prior to spawning. However, all herring known to be in the area were not surveyed because herring had moved into shallow water and began to spawn while the survey was being conducted. Future acoustic surveys will be conducted earlier in the season to avoid this problem. Egg loss of PWS herring was studied during spawn deposition surveys in 1990, 1991, 1994, and 1995. The proportion of eggs lost through physical removal and mortality was investigated to improve diver survey biomass estimates and understanding of the mechanisms controlling early life history survival. Results indicated that egg loss rates are highly variable, site specific and are generally higher than previously estimated. Depth of spawn deposition and wave exposure accounted for much of the variation in instantaneous egg loss rates in the Montague Island area.
