Origin and habitat
Native to freshwater lakes and rivers across Europe, from France and Britain east through Central Europe to the Caspian and Aral Sea basins. The species (Sander lucioperca, also called zander) is the European counterpart to the North American walleye (Sander vitreus), sharing the same genus and many biological characteristics. Pikeperch are predatory cool-water fish that inhabit turbid, deep lakes and slow rivers. Adults reach 1–1.3 m and 15 kg, though culture harvest size is typically 0.5–2 kg. The flesh is white, firm, lean, and delicately flavored, considered one of the premier freshwater food fish in European cuisine. Pikeperch fillets command premium prices in restaurants across France, Germany, Switzerland, and Scandinavia. Aquaculture production is growing, with major research and commercial efforts in France, the Netherlands, and the Czech Republic.

Care notes
A premium cool-water food fish for European aquaponics, directly analogous to walleye in North American systems. Optimal temperature is 20–26°C, with tolerance from 4–30°C. Growth in RAS: 0.5–1 kg in 18-24 months on high-protein pellet (45-50% protein). FCR is 1.0-1.5 in well-managed intensive systems, which is excellent for a predatory species. Stocking density: 20-40 g/L in RAS with good water quality management. Pikeperch tolerate lower light conditions than most culture species and perform better in dim or shaded systems, which suits certain aquaponics greenhouse designs. Water quality must be good: DO above 5 mg/L, ammonia below 0.5 mg/L. The main culture challenges are feed training (pikeperch fingerlings must be weaned from live food to pellets, with variable success rates) and cannibalism in early life stages. Source pellet-trained fingerlings from specialist hatcheries. Pikeperch aquaculture is an active R&D area in Europe; improved domesticated strains are becoming available. Fingerlings from commercial hatcheries in France, the Netherlands, and the Czech Republic. Market value is high ($15-30/kg), making pikeperch one of the most economically attractive freshwater aquaponics species in Europe.
