Region: Southeast AsiaDownload
A feeding demonstration was conducted at Malalag Bay in Santa Maria, Davao del Sur, Philippines to demonstrate the growth of milkfish (Chanos chanos) in marine cages using a soy-based, extruded feed. Milkfish fingerings of about 56 g were stocked into three, 216-m3 cages at 6,875 fish per cage. Fish in all cages were fed a 34% protein, 9% fat (34/9) feed formulated with soybean meal as the primary protein source. The feed was produced domestically in the Philippines. After 213 days of culture, milkfish reached an average size of 665 g with a gross average harvest of 4,136 kg/cage (19.1 kg/m3), an average survival of 91% and an average FCR of 2.60:1.
