Description A techaique for large-scale production of penaeid prawn seed using a dry
microparticulate formula feed, NPCL-17, is described. The details of preparing the
feed which is compounded from inexpensive, locally available raw materials such
as groundnut oil cake, fish meal, dried mantis shrimp, prawn waste and tapioca
and fortified with vitamins and minerals are given. The larvae are grown in outdoor
tanks filled with 2 m' of seawater, filtered through 60-micron mesh nylobolt
cloth. The daily ration of formula feed is offered in 4 equal instalments at 6
hourly intervals and the larval tanks are vigorously aerated. Apart from providing
nutrition for the larvae, the feed, under the influence of sunlight, helps to create
a natural ecosystem conducive for their survival. The easy-to-dispense dry feed
has greatly simplified the larval rearing procedures and has given an average survival*
rate of 66.7% from nauplius to postlarva. The rationale of the feeding schedules
and the particle size of the feed offered are discussed in the light of the
changes taking place in the functional morphology of the feeding appendages
during larval development.
