%X the embryonic and early larval development of the southern hake, merluccius australis, is described for the first time using laboratory reared specimens. the eggs are pelagic, measure 0.9-1.1 mm diameter, have smooth chorion, unsegmented yolk and one 0.19-0.27 mm diameter oil globule. at a temperature of 11.5 oc the larvae hatch 7 days after fertilization, at an average size of 2.8 mm nl (notochord length); yolk reserves are exhausted in 9 days. yolk-sac larvae grow at a linear rate of 0.15 mm/day. growth rate is reduced to 0.08 mm/day from first feeding to 45 days (multiple slope test, p < 0.001)
