Effect of feeding rate on the survival and growth of milkfish (Chanos chanos) fry in a controlled environment
MetadataShow full item record
The optimum daily feed allowance varies with species, age, size, frequency of feeding, culture procedures, quality of feed and water quality. This experiment indicated that with a diet containing 40% protein and 3,450 kcal of M.E. per kg, a feeding rate of 16-20% of the biomass is optimum for satisfactory survival and growth of fry raised in a controlled environment. Increasing the feeding level beyond this value was not beneficial but in turn increased the ammonia-nitrogen concentration to a level which is harmful to the fish.

Kumagai, Shigeru; Castillo, Nelson (Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)Fry shrank immediately after they were preserved in formalin, but from the second week onwards shrinkage was almost nil. Fry in freshwater formalin solutions shrunk less than those in seawater formalin solutions. It is ...
Kumagai, Shigeru; Bañada, Vicente C.; Castillo, Nelson M.; Unggui, Abdul S. (Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)The results are presented of a study of milkfish fry occurrence in the Philippines, namely at Magaba and at Tubog. There were 2 peaks of fry occurrence in the latter, one in May and another in October, whereas only one ...
Smith, Ian R. (International Center for Living Aquatic Resources Management; Aquaculture Department, Southeast Asian Fisheries Development Center, 1981)The fry and fingerling industry of the milkfish (Chanos chanos Forskal) in the Philippines is alleged to suffer from certain imperfections. Primary among these are an annual shortage of catch necessary to meet the stocking ...Series: ICLARM technical reports; 1 | SEAFDEC Aquaculture Department contribution; No. 93
