Descripción
An intergeneric hybrid between female common carp, Cyprinus carpio communis L. and male mrigal, Cirrhinus mrigala (Hamilton) was successfully produced at this Centre and reared. Its embryonic and larval developmental stages were compared with those of parents and reciprocal hybrid. The mode of development was observed to be similar to that of common carp. Though the percentage of fertilization was high (65–85%), yet survival of post-larvae was quite low, ranging from 30–40% due to occurrence of abnormality in embryos and larvae. Some aspects of morphometry of the above hybrid are described in the present communication.
