Title Eggs and early developmental stages
of Hilsa kelee (Cuvier)
 
Creator Rao, K Satyanarayana
 
Subject Clupeidae
 
Description A type of clupeiod fish eggs 1.005-1.065 mm in diameter with six or seven
oil globules recorded in the plankton off Madras coast from February to April
and in December in 1967 and in January and March in 1968 have been ascribed
to Hilsa kelee (Cuvier) based on the structure of the eggs and larvae hatching
from them, the simultaneous occurrence of ripe fish of the species in inshore
waters of Madras and coincidence of myotome number of larvae with the number
of vertebrae in adult fish.
The newly hatched pro-larva has ellipsoidal yolk sac, thirty six pre-anal
and six or seven post-anal myotomes and small black spots on the dorsal side
of the pro-larva. The three day old pro-larva has three pairs of rudimentary gills,
well-developed pectoral fins, small black streaks on the gut and caudal fin rays
and 42 or 43 myotomes. The eggs appear to tolerate a fairly wide range of
salinity between 26.22 %. and 35.62%,.
