A 1989 estimate shows that there are about 45 salmon farms on the Atlantic Coast (primarily in the Bay of Fundy) and about 150 on the Pacific. The majority of salmon farmers rely on government or private salmon hatcheries to supply them with smolts to grow to market size. Trout farming was purported in 1970 as having the potential of a multimillion-dollar industry in the prairie land of Manitoba, Alberta, and Saskatchewan, where there are many potholes (actually, small lakes and sloughs). Farmers had tried unsuccessfully to drain these potholes so that the land could be used for agricultural crops.
Mollusks There have been few changes in oyster culture techniques. Most of the output comes from public grounds, where some quasi-aquacultural methods are practiced, such as spreading oyster shells (cultch) to collect wild spat. Private oyster farming on leased sea bottoms with protection from predators by off-thebottom culture is expected to continue because of the higher returns. Oyster culture in the Pacific Northwest involves intensive techniques, including the use of hatcheries. "Remote setting" is now being used on the Pacific Coast of North America: Hatchery larvae ready for final settlement are shipped to selected locations, where they will metamorphose and set on cultch in tanks; the cultch can then be placed in oyster beds.
