THE PERCH, (Perca fluviatilis,)
Seldom grows to any great size; yet we have an account of one which is said to have weighed nine pounds. The body is deep, the scales rough, the back arched, and the side-lines placed near the back. For beauty of colours, the Perch vies with the gaudiest inhabitants of the waters; the back glows with the deep reflections of the brightest emeralds, divided by five broad black stripes; the abdomen imitates the tints of the opal and mother-of-pearl; and the ruby hue of the fins completes an assemblage of colours most harmonious and elegant. It is a gregarious fish, and is caught in several rivers of these islands; the flesh is firm, delicate, and much esteemed.
It is generally believed that a pike will not attack a full-grown Perch: he is deterred from so doing by the spiny or dorsal fin on the back, which this fish always erects at the approach of an enemy. Perch are so voracious, that, if an expert angler happens to find a shoal of them, he may catch every one. If, however, a single fish escape that has felt the hook, all is over; as this fish becomes so restless, as soon to occasion the whole shoal to leave the place. Perch are so bold, that they are generally the first fish caught by a young angler; they will also soon learn to take bread thrown into the water to feed them. A large-sized Perch weighs about three pounds; but generally the Perches caught in ponds do not exceed eight or ten ounces in weight.
THE BASSE, OR SEA PERCH, (Labrax lupus,)
Is found in abundance on our southern coasts, and is still more common in the Mediterranean. It has one long dorsal fin, like the ruffe. The flesh of this fish is highly esteemed.
