of fish and many more marine invertebrate species have been identified. Bromophenols, which are produced by marine algae, give marine animals an odor and taste that is absent from freshwater fish and invertebrates. Also, a chemical substance called dimethylsulfoniopropionate (DMSP) that is found in red and green algae is transferred into animals in the marine food chain. When broken down, dimethyl sulfide (DMS) is produced, and is often released during food preparation when fresh fish and shellfish are heated. In small quantities it creates a specific smell one associates with the ocean, but in larger quantities gives the impression of rotten seaweed and old fish. Another molecule known as TMAO occurs in fishes and gives them a distinct smell. It also exists in freshwater species, but becomes more numerous in the cells of an animal the deeper it lives, so fish from the deeper parts of the ocean have a stronger taste than species that live in shallow water. Eggs from seaweed contain sex pheromones called dictyopterenes, which are meant to attract the sperm. These pheromones are also found in edible seaweeds, which contributes to their aroma.

Health hazards

There are numerous factors to consider when evaluating health hazards in seafood. These concerns include marine toxins, microbes,

are among the more common food allergens. Most of these dangers can be mitigated or avoided with accurate knowledge of when and where seafood is caught. However, consumers have limited access to relevant and actionable information in this regard and the seafood industry's systemic problems with mislabelling make decisions about what is safe even more fraught. Ciguatera fish poisoning (CFP) is an illness resulting from consuming toxins produced by

which bioaccumulate in the liver, roe, head, and intestines of reef fish. It is the most common disease associated with seafood consumption and poses the greatest risk to consumers. The population of plankton that produces these toxins varies significantly over time and location, as seen in red tides. Evaluating the risk of ciguatera in any given fish requires specific knowledge of its origin and life history, information that is often inaccurate or unavailable. While ciguatera is relatively widespread compared to other seafood-related health hazards (up to 50,000 people suffer from ciguatera every year), mortality is very low. Scombroid food poisoning, is also a seafood illness. It is typically caused by eating fish high in histamine from being stored or processed improperly.

Mislabelling

Due to the wide array of options in the seafood marketplace, seafood is far more susceptible to mislabeling than terrestrial food. There are more than 1,700 species of seafood in the United States' consumer marketplace, 80 – 90% of which are imported and less than 1% of which are tested for fraud. However, more recent research into seafood imports and consumption patterns among consumers in the United States suggests that 35%-38% of seafood products are of domestic origin. consumption suggests Estimates of mislabelled seafood in the United States range from 33% in general up to 86% for particular species.

were particularly susceptible to mislabelling, and seafood substitution was the most common type of fraud. Another type of mislabelling is short-weighting, where practices such as overglasing or soaking can misleadingly increase the apparent weight of the fish. For supermarket shoppers, many seafood products are unrecognisable fillets. Without sophisticated DNA testing, there is no foolproof method to identify a fish species without their head, skin, and fins. This creates easy opportunities to substitute cheap products for expensive ones, a form of economic fraud. Beyond financial concerns, significant health risks arise from hidden pollutants and marine toxins in an already fraught marketplace. Seafood fraud has led to widespread keriorrhea due to mislabeled escolar, mercury poisoning from products marketed as safe for pregnant women, and hospitalisation and neurological damage due to mislabeled
