Available in PDF, EPUB and Kindle. Book excerpt: The resilience framework is increasingly used to understand the dynamics of sustainability in coupled social and ecological systems. Resilient ecological systems exhibit high levels of diversity, including species and habitat diversity, and redundancy, all of which are thought to help maintain the system within a domain of attraction. Numerous studies demonstrate the threat posed to natural systems by the introduction of invasive species on a global scale. Over the past century, biological invasion has caused changes in biological diversity and alterations to the structure and function of ecosystems. In Puget Sound, the non-native Pacific oyster (Crassostrea gigas) has been used as a commercial aquaculture species for over a century, despite increasing evidence that its spread threatens ecological resilience of the nearshore system. Interestingly, recent changes in ocean conditions that lessen the invasion threat have been met with alarm in Washington, as they jeopardize the social resilience built on the culture of Pacific oysters. In this case study, I discuss conflicts between social and ecological resilience, and the values that drive those conflicts. I then discuss social adaptation strategies as options to retain social-ecological resilience within the system.

Book excerpt: "Pacific oysters are endemic to Japan, but have been introduced into a number of other countries including Australia. Most of these introductions have been for the purposes of aquaculture, with Pacific oysters the most widely cultured shellfish species worldwide. Pacific oysters were first introduced into south-eastern and western Australian waters for aquaculture. They later found their way into NSW waters, where they have spread and invaded intertidal habitats of many waterways"--Introduction.

This book was released on 2019 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Even though the introduction of the Pacific Oyster, Crassostrea gigas, to the west coast of North America, happened roughly a century ago, it has only been in the past 15 to 20 years that C. gigas has started to become an established and conspicuous species along Southern California's coast. The establishment of C. gigas in Southern California has the potential to heavily influence many native species, as it has done globally. In Southern California, this invasion is particularly relevant for the native Olympia Oyster, Ostrea lurida. The Olympia oyster has both historical and present-day threats to its population, due to overfishing, pollution, and exotic species introductions. Understanding the distribution and demography of both species at the relatively early stage of C. gigas establishment is important for future management of both species. In order to address this, sampling was conducted along the rip rap of the San Diego River, near its connection with the Pacific Ocean. Transects were laid down at the high, mid and low intertidal, and quadrats along these transects were sampled quarterly for one year. Densities, biomass, Condition Index, length frequencies, and Von Bertalanffy growth constants were used to look at the growth of the two species over this time period. For C. gigas, growth lines were also used as a tool to estimate age and growth. This work demonstrated that O. lurida densities were in fact much greater than those of C. gigas, but that these native oysters had greater numbers in the low intertidal and diminished as tidal height increased. Crassostrea gigas numbers also decreased with increase tidal height, although less dramatically than O. lurida. Even though there is a large size difference between the two species, growth rate constants found using the Von Bertanlaffy growth model (k) in the low- and mid-intertidal combined were found to be very similar, indicating similar growth rates. Further analysis of growth rates of C. gigas across tidal zones, using growth lines, demonstrated that the growth rate decreased as tidal elevation increased. This study on the demography on native and invasive oysters in San Diego provides a foundation of baseline scientific information against which future change can be assessed, and can also inform future research directions, such as investigations of how each species interacts independently with their environment and with one another.

This book was released on 2008-02-13 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mass oyster mortalities have been known for many years throughout the world, but no strictly pathological explication has been found. This book describes how environmental influences, reproduction, stress, genetics, pathogens and temperature contribute to oyster summer mortality in France. An interaction model is derived from the results and recommendations are made for forecasting and managing risk factors.
