Oyster farming is one of the most important aquaculture industries in the US. Oysters can be kept up to two weeks after collection at 36–38F in a breathable container. Management also includes regulations controlling harvest totals, efforts, and access; however, no Gulf state has a total allowable catch limit. A variety of volume measures are used, so buyers recommend insisting on easily quantifiable units such as by the piece or by the pound. While there is no national oversight agency for aquaculture in the US, there are extensive regulations in place regarding predator controls, therapeutant use, and disease management. endobj Bottom dredging used to collect Eastern oysters can kill non-targeted species.

Reproductive outputs decreased by 34% and 2% in the Upper and Lower Bay locations, respectively, and increased by 2% at the Mid Bay site. Triploids, because of their extra set of chromosomes, are sterile and possess several characteristics that are ideal for aquaculture. Eastern oyster (Crassostrea virginica) reproduction season coincides with periods of low pH occurrence in estuaries, thus we investigated effects of moderate (pH 7.5, pCO 2 2260 µatm) and severe OA (pH 7.1, pCO 2 5584 µatm; and 6.7, pCO 2 18480 µatm) on oyster gametogenesis, fertilization, and early larval development successes.
