The effect of duration of feeding on survival,growth and production of milkfish, Chanos chanos (Forskal), in brackishwater ponds in The Philippines

Milkfish (Chanos chanos) fingerlings with an average weight of 16.3 g were stocked at 4000 per ha in twelve 500-m² experimental brackishwater ponds. The duration of supplementary feeding using pelletized chick starter (21.15% protein) at a ration of 5% of the biomass, was varied between 0 and 3 months. The duration of supplementary feeding had no significant effect on the survival, growth and production of milkfish. The results indicated that supplementary feeding of milkfish was not necessary at a stocking level of 4000 fish/ha, when adequate pond fertilization was carried out.
