A hardy and fast-growing fish widely farmed for its mild flavor and high protein content.

A deep-water snapper species found on offshore reefs and structures of the western Atlantic. Prized for its bright red color and excellent flavor. Typically schools over rocky bottoms on the continental shelf and slope.

A Eurasian pikeperch species inhabiting large rivers and lakes with slow current and sandy or muddy bottoms. Smaller than its relative the zander (Sander lucioperca), it preys on small fish and invertebrates. Valued as a food and sport fish throughout its native range in Eastern Europe and Asia.

One of the fastest fish in the ocean, known for its incredible speed and importance in sport fishing. A solitary pelagic predator found in tropical and subtropical seas worldwide. Prized for its high-quality, firm white flesh.

The Walleye is a prized North American freshwater game fish, known for its excellent taste and nocturnal feeding habits. Its large, reflective eyes help it hunt in low light, especially in lakes and rivers with turbid waters. Formerly classified as Stizostedion vitreum, it spawns in spring and thrives in cooler, deeper habitats.

One of the largest freshwater fish in Europe, known for its long body and voracious appetite.

A small benthic goby species native to freshwater and brackish habitats in Europe. Characterized by its fused nasal flaps forming a distinctive tube-like structure. Prefers shallow waters with sandy or rocky substrates and abundant vegetation. Nocturnal and bottom-dwelling, it feeds on small invertebrates. Can tolerate brackish conditions and has become invasive in some regions outside its native range.

The White Crappie is a freshwater fish native to North America, recognized by its silvery body with 5–10 vertical dark bars and a slightly elongated shape. It prefers slow-moving or still waters such as lakes, reservoirs, and turbid backwaters. Adults feed primarily on small forage fish like shad, while juveniles consume insects and microcrustaceans.
