Abstract

Studies on the effect of thyroxine on the eggs and postembryonic
g·rowth of Brachydanio rerio, Cyprinus carpio, Labeo rohita, Cirrhina
mrigala and Catla catla have been carried out. The treatments were
given in the dosages ranging from 0.025 to 0.20 mg. Lower doses of
0.025 to 0.075 mg were effective in reducing the hatching period,
accelerating the yolk absorption and improving the growth of
postembryonic s~ages in case of all the five species. Higher doses of
0.15 to 0.20 mg were found to reduce the survival significantly in B.rerio,
C. carpio, L. rohita and C.mrigala.
