Feed and growth

Feed protein: 40% target
Daily feed (warm): 2.00% of body weight
Daily feed (cool): 0.80% of body weight
Max density: 30 g per litre

A 1200 g adult eats about 24.0 g of feed per day at optimum. 10 fish at adult size: ~240 g daily.

Origin and habitat

Native to large rivers, reservoirs, and lakes across central North America, from the Great Lakes south through the Mississippi and Ohio River basins to the Gulf Coast. The species (Morone chrysops) is the smaller parent in the hybrid striped bass cross (white bass male x striped bass female = sunshine bass). Adults reach 30–45 cm and 0.5–2 kg. White bass are schooling predators found in open water, where they feed on shad, minnows, and invertebrates. The flesh is white but softer and less premium than striped bass, with a stronger flavor that some find less desirable. White bass are popular sport fish across the Midwest and southern US but have limited commercial market value compared to striped bass or the hybrid.

Care notes

A warm-water Morone species with limited direct aquaponics value as a standalone food fish; included primarily because it's the paternal parent of the commercially important hybrid striped bass (white bass male x striped bass female = sunshine bass). Optimal temperature is 22–28°C, with tolerance from 5–30°C. The broader warm-water tolerance compared to striped bass (which stresses above 26°C) is the trait the hybrid inherits. Growth: 300–600 g in 12-18 months on pellet (38-42% protein). FCR is approximately 1.8-2.5. White bass accept pelleted feed more readily than striped bass and are generally easier to culture in intensive conditions, but the smaller maximum size and less desirable flesh quality (softer texture, stronger flavor) compared to the hybrid or pure striped bass make them a poor standalone choice for aquaponics production. The flesh has a prominent red lateral line muscle (bloodline) that must be trimmed for best flavor; this is a common complaint from consumers. For aquaponics, the hybrid striped bass is superior in every production metric: larger adult size, better flesh quality, better FCR, and higher market value. White bass culture exists primarily at hatcheries that maintain male broodstock for hybrid production crosses. Fingerlings are available from state hatcheries that manage white bass populations. Legal in most states without special permits. Not recommended as a primary aquaponics species.
