Select options.  Their sex can be determined by examining the gonads, and it can change from year to year, normally during the winter.  It is now the most widely farmed and commercially important oyster in the world, as it is very easy to grow, environmentally tolerant, and easily spread from one area to another. Figure 4.  The main causes of mortality in the Pacific oysters are natural mortality (age), predators, disease, environmental conditions (ice, freak winds), competition for space (crowding of cultch), silting (sediment runoff from land), and cluster separation (process of breaking up clusters of oysters into as many individual oysters as possible). M. gigas is an estuarine species, but can also be found in intertidal and subtidal zones. Its size makes it also perfect for grilled or baking.  The larvae move through the water column via the use of a larval foot to find suitable settlement locations.  The expression of genes such as arginine kinase and cavortin are particularly important in regulating the metabolic response of this species to stress events including the reduction of seawater pH, as observed under ocean acidification.  In 2006, the 23 Pacific oyster farms throughout New Zealand covered a total of 750 hectares of marine space and produced 2,800 tonnes of product per year.
