. Fig. 3 Scale of dwarfed wild carp no. 6 with 5 annuli; the second annulus (for 1958) is strongly intercepted, approx. xl6. experiment may have brought about the development of a small gape of mouth? The size of mouth would be an adaptive eharaeter in Kammerer's (1923) sense then, in spite of criticism of such concepts (Kocstler, 1971). The number of curves of the intestine in experimentally-dwarfed carp varied (4,7,4,4,5,6, respectively) as did other characters (Table 3). Adult domestic carp average six curves to the intestine (Klust, 1939). Hence not all dwarf fish developed fewer curves. R

Adult domestic carp average six curves to the intestine (Klust, 1939). Hence not all dwarf fish developed fewer curves. Rudzinski (1961 ) found, and StefTens (1964) confirmed, that the intestine of wild carp was generally 15-25% shorter than that of domestic carp. Artificially "dwarfed" carp developed the shortest intestine which was less than 50% the length of that of the domestic carp and slightly more than 50% of that of the wild carp. Differences are even more emphasized if related to body weight: the ratio of gut length to body weight is in domestic carp, in wild carp, and in dwarfed carp (Table 3). In spite of experimental conditions of minimal temperature fluctuation, the absence of seasonal changes, and constant feeding throughout the year. 14
