The purpose of this legislation is to officially recognize "Golden Sea Bream" as an acceptable name for a specific fish species known scientifically as Stenotomus chrysops. This aims to clarify how this fish can be marketed and sold in the United States. The key provision of the legislation states that if Stenotomus chrysops is labeled or marketed as "Golden Sea Bream," it will not be considered misbranded or adulterated under the Federal Food, Drug, and Cosmetic Act. This means that sellers can use this name without facing legal issues related to food labeling.
