Abstract

A hybrid, rohu-catla, was produced by crossing male rohu with female
catla. The embryonic and larval developments of this hybrid, when compared with
those of rohu and catla, showed that the development of the hybrid is normal, without
any deformities, and is more or less similar to that of the parental species. The
period of incubation in the hybrid was 15 h 42 min., as against 16 h 40 min. in
catla and 15 h 30 min. in rohu. The hybrid exhibited intermediate characters in
respect of the position of mouth and the nature of lips. The caudal spot in the
hybrid was triangular as in catla, but more prominent. The alimentary canal in
two-day-old larvae of the hybrid was filled with algae and cladocerans, indicating
that feeding had commenced on the second day itself, with yolksac still present.
