Seafood fraud is the practice of misleading consumers about their seafood in order to increase profits. Along with ripping off shoppers, these actions can have negative impacts on marine conservation efforts and human health.

Types of seafood fraud include substituting one species for another without changing the label, including less seafood in the package than is indicated on the label, adding too much ice to seafood in order to increase the weight and shipping seafood products through different countries in order to avoid duties and tariffs.
