dc.description.abstractThis study examined the effects of co-feeding Artemia and commercial feeds on survival, growth and fatty acid composition of silver therapon Leiopotherapon plumbeus early juveniles. Triplicate groups of 36 days post hatch (DPH) early juveniles (17.09 ± 1.69 mm; 0.07 ± 0.02 g) were stocked in nine glass aquaria at 25 individuals per aquarium and reared for 60 days on three feeding regimes: (A) Artemia + powdered commercial tilapia feed (35% crude protein (CP)); (B) Artemia + powdered commercial prawn feed (38% CP); and (C) Artemia nauplii only as the control group. Early juveniles co-fed Artemia and commercial feeds had significantly higher survival (97%) than those fed Artemia alone (86%). Except for the condition factors that were similar to the control group, higher mean total length (30.2 ± 1.3 mm and 27.6 ± 1.2 mm), body weight (401 ± 64 mg and 339 ± 46 mg), length- (SGRL; 0.95 ± 0.07%/day and 0.80 ± 0.07%/day) and weight-specific growth rates (SGRW; 2.85 ± 0.27%/day and 2.58 ± 0.22%/day) were also observed in the co-feeding groups, independent of protein, fat and other nutrient levels in commercial feeds. Higher levels of long-chain polyunsaturated fatty acids were reflected in early juveniles co-fed Artemia and commercial feeds than those fed exclusively on Artemia contributing, in part, to the higher growth and survival observed in the co-feeding groups. Together, these results suggest that co-feeding strategy showed best results in terms of growth and survival, and that commercial feed with 35% protein and 6% crude fat levels may be beneficial in supplementing live feed with essential nutrients to optimize production of silver therapon fry during nursery culture.en
