This hump-backedtenant of our rivers, lakes, and other sheets of water isone of the handsomest of all with its rough bronze-greenbody, dark back, and vertical bands, and very pricklyfront dorsal fin which begins almost above the Perch wanders about in shoals, and is so ravenous. that, when on the feed, the whole number can be caught in a very short time. Even if a hook is lost, the same fish may be re-captured with the missing hook inside its mouth. It is a bold-biting and game little fish, and one is often deceived at the smallness of the specimen that has shown so much fight before being landed. The larger fish are more wary, but even so, I have had splendid bags of Perch which have weighed an average of 2 pounds each. Larger specimens Vvcighing 3 to 4 pounds have fallen to my rod, but the maximum weight is heavier than this. 107 BRITISH FRESH-WATER FISHES The food consists of other fishes—a minnow is a splendidlure for a big Perch—as well as insects in various stages,molluscs, and worms. The favourite feeding-time inSummer is morning and evening, and it is interesting tonotice how a shoal that has been under irritating observa-tion all day suddenly comes on the feed. Spawning takesplace in shallow water where there is a clean bed. Theeggs are not shed
