Phytoplankton : Combination of Cost Reduction and Productivity Enhancement Technology Possible
“The natural food present in ponds produced through fertilization is enough to sustain needs of the fishes during the early stage of culture period
After its separate introduction of 45-days delayed feeding and polyculture technologies in various parts of Cagayan Valley, the fisheries bureau in the region has shown that both can be combined following successful result of its demo project here. The demo project was established in the fish farm of Marcia! Balmores in Barangay Catarawan this town.
Following recommended stocking rate on polyculture, the 1,520 square meter fishpond owned Balmores was stocked with 6,080 pieces size 22 tilapia (80%), and 380 common carp (5%) March 20 this year. The 1,14o pieces hito fingerlings were stocked two months later, or exactly halfway in the culture period to avoid possible predation.
