In any maricuUure practice, availability of seed is one of the
prime requisites for sustaining growth, development and to make
the activity viable ecologically and economically. As the natural
source of seed is often beset with environmental / conservational
problems, the dependable source is production through hatchery
techniques. Uninterrupted production and supply of live feeds alone
can sustain hatchery operations and to feed the emerging larvae or
post larvae with different feed requirements at different stages of
development / growth. Technologies developed by CMFRl in this
line are given in this paper. The method of culturing important live
feed organisms such as micro-algae, rotifers, cladocerans and
Artemia salina along with their harvesting and preservation are
briefly described in this accoun
