Economics is critical to any successful business. Aquaculture is a financially viable option with several potential, but it is also a difficult and capital-intensive enterprise that necessitates close supervision. To be successful, thorough initial preparation and ongoing attention to business finances are required. The economics of aquaculture can be seen from a variety of viewpoints. It might be viewed from the perspective of a single aquaculture business, the entire industry, or the entire nation. Production, technical, or cost issues, as well as marketing issues, can all contribute to an aquaculture project's economic failure. As a result, entrepreneurs who want to run a profitable aquaculture business must pay close attention to economics, particularly marketing issues.
