A hybrid striped bass, also known as a wiper or whiterock bass, is a hybrid between the striped bass (Morone saxatilis) and the white bass (M. chrysops). It can be distinguished from the striped bass by broken rather than solid horizontal stripes on the body. Hybrid striped bass are considered better suited for culture in ponds than either parent species because they are more resilient to extremes of temperature and to low dissolved oxygen.
The striped bass (Morone saxatilis), also called Atlantic striped bass, striper, linesider, rock, or rockfish, is an anadromous Perciforme fish of the family Moronidae found primarily along the Atlantic coast of North America. It has also been widely introduced into inland recreational fisheries across the United States. Striped bass found in the Gulf of Mexico are a separate strain referred to as Gulf Coast striped bass.
Morone is of unknown derivation. The species epithet chrysops is Greek meaning "golden eye." As with other true basses, the dorsal fin is clearly double, separated into spiny and soft-rayed portions. White bass are silvery shading from dark-gray or black on the back to white on the belly. Several incomplete lines or stripes run horizontally on each side of the body. Adults resemble young striped bass, and the two are often confused. However, striped bass have two distinct tooth patches on the back of the tongue, and white bass have one tooth patch. Striped bass have two sharp points on each gill cover, as opposed to white bass which have one, and the second spine on the anal fin is about half the length of the third spine in striped bass, whereas it is about two-thirds the length of the third spine in white bass.
Both species of crappie as adults feed predominantly on smaller fish species, including the young of their own predators (which include the northern pike, muskellunge, and walleye). They have diverse diets, however, including zooplankton, insects, and crustaceans. By day, crappie tend to be less active and will concentrate around weed beds or submerged objects, such as logs and boulders. They feed during dawn and dusk, by moving into open water or approaching the shore.
