Fish are vertebrate aquatic animals. They bear gills but neither have digits nor true spines. There are more than 34,000 species worldwide, with the first one appearing as early as the Cambrian era. Thus, it has played a vital role not only in the ecosystem, but also to humans, as fish has been a significant source of protein and other nutrients. In the world of fishery and culinary, fish may include shellfish. Among the shellfish are crustaceans, echinoderms, and mollusks.
Still, fish is one of the most popular and sought-after foods in the world. It ranges from mild to full flavor. And, it is a versatile ingredient that can be used in almost all recipes. Not to mention that it’s beneficial to human health too!
