In your first job in aquaculture, you will probably stock ponds, feed fish, monitor water quality, check for diseases, harvest fish, and maintain equipment. If you become a manager, you will supervise pond workers, plan production schedules, purchase feed and equipment, and plan harvesting, processing, and marketing.
An aquaculturist can work for a corporation or an independent fish farmer. Some large operations have their own feed mills and fish processing plants, as well as ponds for raising fish. Companies hire aquaculturists as technicians to test water quality or to examine fish for diseases. Feed companies and equipment manufacturers hire aquaculturists to market their products to fish farmers.
To be an aquaculturist you should be interested in agriculture, since aquaculture is a type of farming. An entry-level position usually requires a high school education. Employees working on the pond bank need to know how to maintain and repair farm equipment. Managers of aquaculture operations often have college degrees, and need to understand water quality, nutrition, business, and economics.
In high school, take courses in the repair and maintenance of machinery and engines, welding, construction, and other shop classes. Accounting, marketing, and other business courses are also useful.
