Due
to the geographic isoLation and the methods of cuLture, the degree of
domestication differed markedLy between the European and the Far Eastern com—
mon carp.
Characteristics infLuencing the seLective breeding incLude its high
fecundity and asymmetricat frequency distribution of size.

1) Mass seLection of the Largest individuaLs was found to be not effec—
tive for improving growth rate. Z) Captive popuLations are prone to-inbreeding
;resuLting in a reduced growth rate and disease toLerance, Crossbreeding is the
effective method of seLective improvement: heter0sis of growth has been
repeatedLy; it aLso permits the combination of the fast growth of
