Mariculture is a complicated business and anyone who intends entering it should undertake extensive research on the topic. It requires a large investment of time and money over a period of years. By conducting a feasibility study before starting a farming venture, you can determine how much it will cost to operate a farm and if the right conditions for growing a particular species are available.

Given the high start-up costs, most successful mariculture operations target high-value fish, such as ornamental fish, as well as food fish, such as red snapper, salmon, and eels. Shellfish mariculture has a broader product range including clams, oysters, shrimp, scallops, and crabs. Algae are often produced with finfish or shellfish to provide a food source for the primary product.

A major cause of failure in any aquaculture or mariculture operation is poor marketing. In mariculture, farmers are competing with wild-caught commercial species. This can be beneficial, given wild stocks are declining and seasonal availability can produce supply shortages that a producer can fill if he or she can arrange harvests for the times of shortages. However, if wild catches are plentiful, the producer may not be able to sell the product at a price that covers costs.
