[A corruption of barse.] A spiny-finned kind of perch used for food. There are many kinds, including the black and rock bass and sea bass of America, the common European bass, the striped bass, the white or silver bass of the American lakes; and the brasse or yellow bass. The black bass builds on the bottom a saucer-like nest, where it deposits its eggs, and where, when hatched, the fry are carefully protected.
