Most milkfish production in the Philippines is carried out in semi-intensive pond systems in small fish ponds of 1 to 5 ha. Earlier investigations reported feeding rates with 4% of the fish body mass per day as favourable for milkfish growth. However, recent investigations on the intake of supplemental feeds and natural food by the milkfish in small experimental ponds showed, that only a part of these supplemental feeds was taken in directly by the fishes (KÜHLMANN et al. 1995, 4th Asian Fisheries Forum). This study aimed to find out whether this holds true for commercial milkfish ponds as well. The daily diet intake was estimated with microscopic and gravimetric analyses of stomach contents and calculation with the MAXIMS software program. more...
