A variety of tenacious myths critical of marine aquaculture practiced in the United States have persisted for decades to be presented as facts to the public and Congress. The reality is U.S. fish and shellfish farmers culture aquatic animals and plants within a very complicated and expensive legal, regulatory, husbandry, and science-driven environment.

Careful financial management is essential for the success of an aquaculture business. While financial management is a complex topic that can be approached from many perspectives, there are some key questions that the manager of an aquaculture business must answer affirmatively to be successful.

This publication, written by Dr. Carole Engle, a specialist in aquaculture economics, outlines the types of analyses and financial statements required to answer these critical questions.

Cash flow problems are one of the most common types of financial problems in aquaculture businesses. This publication, written by Dr. Carole Engle, a specialist in aquaculture economics, addresses the question of whether the business can generate enough cash when needed to pay its bills (liquidity).

This guide was created to help the emerging seaweed industry understand the prevailing regulatory requirements surrounding the production of seaweeds as food. There are currently two regulations that are being used to regulate seaweeds at either the federal or state level: the Current Good Manufacturing Practice, Hazard Analysis, and Risk-Based Preventive Controls for Human Food (GMP/PCHF) regulation and the Seafood Hazard Analysis Critical Control Point regulation. This guide will help the reader understand the similarities and differences between the two regulations and help the reader understand how their operation might be regulated.
