The $35 million industry, which includes the Sydney rock oyster, Pacific oyster and the native, flat oyster, has been threatened with poor harvests due to acidification of oceans. Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.Domesticated animals are known as breeds, normally bred by a professional … The Sydney rock oyster, ... A lot of research has been done over recent years to develop QX-resistant oysters using selective breeding techniques. Her research suggests one way that may help oyster farmers adapt. Selective breeding of Saccostrea glomerata is one measure addressing these problems by producing fast‐growing, disease‐resistant oysters. “Selective breeding is the past, present, and future of oyster aquaculture in the eastern U.S.” he explains. In New South Wales, the Department of Primary Industries has done studies on the Sydney rock oyster to examine the potential for selective breeding to … Fitzer recently studied Sydney rock oysters that had been selectively bred in … In New South Wales, the Department of Primary Industries has done studies on the Sydney rock oyster to examine the potential for selective breeding to … In 2011 31 million pounds of oysters were harvestede with a dockside value of approximately $135 million (National Marine Fisheries Service).That is probably a low estimate of the overall value of the oyster because it does account for the ecological value of the fish species that use oyster … good oyster growth also promoted disease . The Australian edible oyster industry has been severely impacted by disease and declining yields since the 1970s. The Australian Pacific oyster selective breeding program commenced in 1997. In this study, we used proteomics to investigate the molecular differences between oyster populations in adult Sydney rock oysters and to identify whether these form the basis for observations seen in larvae. In 2005, after 6 generations of breeding, it was apparent that there were limitations to the breeding strategy. Farmers report that selected oysters have different growth characteristics than their wild counterparts using … “We overcame oyster diseases through resistance breeding dating back to the 1960s, and disease resistant, fast-growing domesticated oysters underpin most of the aquaculture industry today.” Nonetheless we can now successfully demonstrate that through breeding technologies, specifically selective breeding and triploidy, our lines show significant improvement over wild oysters in this area and a farmer can consistently harvest at least 60% of the seed bought – a feat Oyster culture is one of the most prominent forms of marine aquaculture in the U.S. Housed in the Aquaculture Genetics and Breeding Technology Center (ABC), the objective of the program was to develop … A selective breeding program for Crassostrea virginica was established in 1997 as part of an initiative in Virginia to address declining oyster harvests caused by the two oyster pathogens Haplosporidium nelsoni (MSX) and Perkinsus marinus (Dermo). All objectives of the study were met. Research has also been conducted to develop triploid oysters—oysters with three sets of chromosomes instead of the normal two. The Fisheries Research and Development Corporation financially supported the Sydney Rock Oyster breeding program from January 1997 - June 2002.
