Survey on the use of natural food and supplemental feed in commercial milkfish farms on Panay, Philippines
MetadataShow full item record
This study evaluated the feed intake of the milkfish (Chanos chanos Forsskål) in commercial brackishwater ponds under different management regimes. Feed intake and growth were compared between a rather intensive culture management in a fish farm of 1 ha pond size and a semi-intensive one, with a total pond area of 30 ha. The data suggested a direct consumption of only 12 % of the supplemental feed in the intensive farm, leading to a wastage of high quality fish feed and a significantly lower specific and metabolic growth rate (P< 0.001) than in the semi-intensive system without any supplementation and only relying on abundant natural food through fertilization. These results suggest that a heavy reduction in, or even the abandonment of the use of, supplemental feed for milkfish culture would be more cost-effective.

Lee, Dong-Liang; Liao, I-Chiu (Aquaculture Department, Southeast Asian Fisheries Development Center, 1976)In studying the nutritional requirements of young milkfish experiments were conducted to develop a purified test diet. Mixtures of the purified constituents tested were: vitamin-free casein, vitamin-free gelatin, supplemented ...
Potential of feed pea (Pisum sativum) meal as a protein source in practical diets for milkfish (Chanos chanos Forsskal) Borlongan, Ilda G.; Eusebio, Perla S.; Welsh, Tim (Elsevier, 2003)A 12-week feeding trial was conducted to evaluate the use of feed pea meal as a dietary protein source for juvenile milkfish. Six isonitrogenous (30% crude protein) and isocaloric (16.5 kJ/g) practical diets were formulated. ...
Efficacy of poultry by-product meal as an effective alternative to fish meal in aquaculture feed for milkfish Chanos chanos Sugita, Tsuyoshi ; Gavile, Amafe B.; Sumbing, Joemel (Japan International Research Center for Agricultural Sciences, 2020)We verified the efficiency of poultry by-product meal (PBM) as a substitute for fish meal (FM) in feed for juvenile milkfish (Chanos chanos). Juveniles (mean 48.0 g) were fed for 12 weeks with two experimental feeds ...
