Delayed Feeding Is Practicable in Polyculture
The 45-day delayed feeding, a technique for saving on feed cost, can be practiced in polyculture, or the culture of different fish in one pond.
This was found in a demonstration project of the Bureau of Fisheries and Aquatic Resources Region II (BFAR Region II) conducted in a fish farm in Barangay Catarawan in Piat, Cagayan.
Following the recommended stocking rate of 5 fingerlings per square meter in polyculture, 6,080 size 22 tilapia (80%) and 380 common carp (5%) fingerlings were stocked into the 1,520-square meter fishpond of project-cooperator Marcial Balmores last March. Two months later, 1,140 catfish or hito (15%) fingerlings were stocked. Commercial or artificial feeds were introduced 45 days later to save on feed cost.
