Mugil cephalus in ripe condition collected from inshore catches at Muttukadu
near Madras were induced to breed using HCG and ovaprim to study the
embryonic and larval development. Samples of unfertilised eggs and various
developmental stages from fertilization through embryonic and larval stages
were preserved for further micrographic studies. Rate of fertilization was
determined at the time of blastodisc formation and was 90 %. Of the total
number of 1.46 million eggs, 1.26 million were fertilised. The pre-hatched
embryo was deeply pigmented, exhibited twitching movements and lay curved
over the yolk mass. After an incubation period of 30-32 hrs, the embryo hatched
out. The newly hatched out larvae measuring 2.29 mm, were transparent with
a large oval head, a well defined yolk sac and short tail encircled by a
continuous finfold. hlouth formation was complete and the larvae started
feeding on 3rd day of hatching. The paper presents the results of detailed
studies of embryonic and larva1 development and the time scale established
for critical stages of development.
