The waste effluents from intensive fish culture have
been a major concern as a source of pollutants to
natural waters and various mitigative measures have
been considered (Cowey and Cho, 1991; Pillay, 1992).
Those wastes can be reused as a valuable resource in a
integrated aquaculture system to generate natural food
for culture of filter feeder species, e.g., tilapia (Lin et
al., 1989, 1993).
The present experiment is to determine the
productivity and practical stocking ratio of catfish and
tilapia to be CO-cultured in ponds.
