There are approximately 2.3 million farms in the United States, ranging in size from small part-time farms to very large operations. Regardless of size, all farms are a form of business and can be organized or structured in several ways. Individuals involved in the business of fish farming need to be aware of the various organizational structures available to them, including sole proprietorship, partnerships (general and limited) and corporations (regular and subchapter-S). . The specific circumstances of the fish farm business dictate which of these structures is most suitable. For example, large farms with numerous employees and a large investment requirement may find it advantageous to consider a more formalized structure, such as a corporation.
