Roundfish

Roundfish is a general term used to describe a group of marine fish characterized by their relatively cylindrical or rounded body shape, as opposed to the flattened or laterally compressed bodies of many other fish species. This classification is not a strict scientific taxonomy but rather a common descriptive grouping based on morphology. Many fish commonly referred to as roundfish are found in temperate and cold waters of the Atlantic and Pacific Oceans.

Examples of fish often categorized as roundfish include cod, haddock, pollock, and whiting. These species are typically demersal, meaning they live and feed near the seabed, and are often found in schools. Their rounded body shape is advantageous for swimming through the water column and for maneuvering in their natural habitat. Commercially, many roundfish species are important food sources, forming the basis of significant fisheries worldwide. Their flesh is generally white, flaky, and mild in flavor, making them versatile in culinary applications. The term "roundfish" is most frequently used in the fishing and seafood industries.
