| Abstract | The relative contribution of natural food organisms present
in a typical brackishwater prawn culture pond system to the
growth and survival of Penaeus monodon postlarvae and juveniles
was estimated using the food conversion ratio C FCR> as an index
of nutritional efficiency. Twenty- day old postlarvae of weight 1 8
mg and length 11 . 4 mm were reared in 0. 15 - cm mesh, 3 m x 1 m x
1 . 75 m nylon net cages installed in an intensive commercial prawn
grow out pond. Th e cages were either open to the bottom to allow
the prawns access to benthic food organisms, or were suspended
off bottom to prevent access to this food source . In two of the
treatments, prawns were given commercial feed equivalent to 10%
of their body weight.
Natural food constituted about 5 1 % to 89% of the total food
intake of the prawns during the two month s experimental culture
period Con the assumption that the feeding efficiency of the
prawns was 1 00%>. At the end of the c ultu re period, the prawns
that received supplementary feed both in the cages that allowed
access to benthos and those that did not, were significantly
C P plankton and other food organisms were dilute d
during water exchanges which start e d from the fifth week of the
culture period, and c)c hanging food habits or food preferences
of t h e prawns as they grew larger. |
