Abstract
Five purified microbound diets containing 1% of 18:2n − 6, 18:3n − 3, 20:4n − 6, or n − 3 highly unsaturated fatty acids (HUFA: 60% 20:5n − 3 + 40% 22:6n − 3) in addition to 8% 18:1n − 9, and a control diet containing 9% 18:1n − 9 were fed to milkfish fry or late postlarvae for 30 days (Trial 1) and 35 days (Trial 2). The salinity was 16–17‰ and temperature was 27 ± 1 °C during the culture periods. A completely randomized design with three replicates per treatment per trial was followed. In each trial, 60 fish (5mg, 6mm) were stocked per 301 oval plastic tank and fed the experimental diets at 20% of biomass per day.
Survival of 100% observed for all groups in both trials demonstrated that the milkfish fry reared in brackish water utilized the test diets. Specific growth rates did not differ significantly among treatments (P 0.05), with values of 9.5–9.9% and 10.0–10.3% in Trials 1 and 2, respectively. Weight, length and feed conversion ratio of milkfish fry fed the various diets also did not differ significantly (P 0.05). Although not significantly differentiated in Trial 1 (P 0.05), incidence of eye abnormality was highest in milkfish fry fed the 18:1n − 9 diet in Trial 2 (P 0.05).

Changes in length and weight of milkfish fry preserved in formalin
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 ... -
Milkfish fry occurrence pattern in two localities along the Western Coast of Panay Island
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 ... -
The economics of the milkfish fry and fingerling industry of the Philippines
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
