Bull Trout

Bull Trout, a loose name for several species of trout (q.v.). Among a number of so-called bull-trout Dr. Gunther found young salmon, salmon trout, and the sewin or grey trout; and it is to this last-named form, probably only a variety of the salmon trout, that the name should be confined. This fish reaches a length of about 3 ft,, and is found in Wales, Cornwall, Dorset, Cumberland, the north of Ireland, and on the Continent. The young lose the parr-marks early, and are then silvery with a greenish tinge; in older fish the back is greenish-brown, in the spawning season the belly becomes dark-brown in the male, but the silvery tinge persists in the female. The gill-cover is square, and is proportionately larger than in the salmon (q.v.), as are also the teeth; and the flesh is paler and of less delicate flavour. The tail is convex owing to the growth of the central rays. The name is sometimes given to Salmo hucho, a large charr (q.v.) from the Danube.
