PRELIMINARY STUDY ON THE REARING OF CHILKA PRAWN("KANTALA ")PENAEUS INDUS H. MILNE -EDWARD IN THE BRACKISH WATER PONDS AT KESHPUR (ORISSA)

Abstract

Results of the experimental rearing of Penaeus indicus without
supplemental feeding in the unfertilized brackishwater ponds in
the fore-shore of the Chilka lake are presented in this paper.
Higher rate of survival was recorded lin the experiment where
advanced juveniles were stocked and lower rate of survival was
recorded where early juveniles were stocked. The average
growth rate recorded from the rearing experiments was higher
than the average growth rate of Penaeus indicus recorded from
the adjoining Chilka lake which indicates the promising future
of prawn farming in and around the Chilka lake. Analysis
of gut contents revealed that Penaeus indicus could efficiently
utilise the algal and higher plant matter present in the ponds.
No noticeable differences in daily growth rates were noticed
between early and advanced juveniles in the rearing experiments
