Ecological and Genetic Implications of Aquaculture Activities
Author: Theresa M. Bert
Publisher: Springer Science & Business Media
ISBN: 140206148X
Category : Technology & Engineering
Languages : en
Pages : 537
Book Description
In this book, numerous prominent aquaculture researchers contribute 27 chapters that provide overviews of aquaculture effects on the environment. They comprise a comprehensive synthesis of many ecological and genetic problems implicated in the practice of aquaculture and of many proven, attempted, or postulated solutions to those problems. This is an outstanding source of reference for all types of aquaculture activities.

Decline of the Steller Sea Lion in Alaskan Waters
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309086329
Category : Science
Languages : en
Pages : 217
Book Description
For an unknown reason, the Steller sea lion population in Alaska has declined by 80% over the past three decades. In 2001, the National Research Council began a study to assess the many hypotheses proposed to explain the sea lion decline including insufficient food due to fishing or the late 1970s climate/regime shift, a disease epidemic, pollution, illegal shooting, subsistence harvest, and predation by killer whales or sharks. The report's analysis indicates that the population decline cannot be explained only by a decreased availability of food; hence other factors, such as predation and illegal shooting, deserve further study. The report recommends a management strategy that could help determine the impact of fisheries on sea lion survival-establishing open and closed fishing areas around sea lion rookeries. This strategy would allow researchers to study sea lions in relatively controlled, contrasting environments. Experimental area closures will help fill some short-term data gaps, but long-term monitoring will be required to understand why sea lions are at a fraction of their former abundance.

Sampling Rare or Elusive Species
Author: William Thompson
Publisher: Island Press
ISBN: 1610911067
Category : Nature
Languages : en
Pages : 447
Book Description
Information regarding population status and abundance of rare species plays a key role in resource management decisions. Ideally, data should be collected using statistically sound sampling methods, but by their very nature, rare or elusive species pose a difficult sampling challenge. Sampling Rare or Elusive Species describes the latest sampling designs and survey methods for reliably estimating occupancy, abundance, and other population parameters of rare, elusive, or otherwise hard-to-detect plants and animals. It offers a mixture of theory and application, with actual examples from terrestrial, aquatic, and marine habitats around the world. Sampling Rare or Elusive Species is the first volume devoted entirely to this topic and provides natural resource professionals with a suite of innovative approaches to gathering population status and trend data. It represents an invaluable reference for natural resource professionals around the world, including fish and wildlife biologists, ecologists, biometricians, natural resource managers, and all others whose work or research involves rare or elusive species.
