Milkfish (Chanos chanos) fry with an average weight of 40 mg per fish were stocked in 60-l wooden-glass aquaria filled with 30 l of filtered sea water with a salinity of 32–34 p.p.t. and a temperature of 25–28°C. They were fed diets containing 20, 30, 40, 50 and 60% protein and 2740 kcal of digestible energy per kg at a daily rate of 10% of the biomass for a period of 30 days. Fish which were fed the diet containing 40% protein had the highest weight gain which was significantly higher (P < 0.05) than those of fish receiving the lower dietary levels of protein. Slightly lower weight gains were obtained when fish were fed diets containing 50 and 60% protein. Although feed conversion values were not statistically different (P < 0.05) among all treatments, the value for the 40% protein diet (1.96) was the best. The mean survival rates were low for all treatments but was highest for the 40% protein diet. No significant difference (P < 0.05) was found in the survival rates of fish receiving different treatments. Results show that a dietary level of 40% protein was required by milkfish fry for maximum growth, efficient feed conversion and high survival rate.

Yolk resorption, onset of feeding and survival potential of larvae of three tropical marine fish species reared in the hatchery This paper provides basic early life-history information on milkfish (Chanos chanos), seabass (Lates calcarifer) and rabbitfish (Siganus guttatus) which may explain in part the observed differences in their survival ...
The effect of various salinity levels and stocking density manipulation methods on the survival of milkfish fry (Chanos chanos Forsskal) during storage Quinitio, Gerald F.; Juario, Jesus V. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)Results of the study indicate that the survival rate and increase in body weight did not differ significantly at different salinity levels or at different stocking density manipulation methods. A significant interaction ...
Smith, Ian R.; Chong, Kee-Chai (Aquaculture Department, Southeast Asian Fisheries Development Center; International Development Research Centre; Island Publishing House, Inc., 1984)Historically, milkfish (Chanos chanos Forsskal) has been the premier aquaculture product in Indonesia, the Philippines, and Taiwan. However, there are significant differences in the industry's performance among and within ...
