Fortified diets enhance milkfish seed production

By Development Communication Section

AQD researcher Ms. Ofelia Reyes shared the results of her study “Optimization of seed production of milkfish, Chanos chanos, Forsskal through feeding fortified diets to broodstock: Effects on eggs and fry quality” on 14 August.

Ms. Reyes noted that there is better survival rate of milkfish fry from broodstock fed with diet fortified with beta carotene and arachidonic acid. Furthermore, she observed that the condition factor of aging broodstock as well as the quality and quantity of spawned eggs were also improved. She explained that when larvae were co-fed with enriched rotifer and milkfish larval diet, low incidence of abnormality in fry was observed after rearing in nursery ponds. She concluded that in terms of egg viability, hatching rate and the number of normal larvae there is a significant difference between the broodstock fed with fortified diet and those fed the regular or non-fortified diet (p<0.05).
