Ha Le Thi Loc, Nguyen Thi Thanh Thuy

Abstract


Newborn Tomato Anemonefish (Amphiprion frenatus Brevoort 1856) from egg batch were divided into 4 treatments in triplicate. Open culture system included 15 liter glass tanks with 40 fish/tank. The fish were promptly separately fed with 4 different feeding regimes. The results showed that the survival of the fish fed on rotifers (Brachionus plicatilis) (5-7 ind./ml) combined with Nannochloropsis oculata  (104-106 cells/ml) (after one day of hatching) and nauplii  Artemia  (57 ind./ml) (after three days of hatching) was significantly higher (70.83 to 72.50%) compared to  those of the fish fed on nauplii Artemia instead of rotifers (10.83 to  27.50%). The  average  length of 30-day old fish fed on rotifers combined with Nannochloropsis oculata and nauplii Artemia (19mm) was significantly higher than those of the fish fed on comrnercial diet (Frippak 300)  instead of nauplii Artemia (14mm). In addition,  the 30 day old fish fed on rotifers was in similar length (SD: ±0.71 to ± 0. 74) compared to those of the fish fed on nauplii Artemia instead of rotifers (SD: ± 0.1 to ± 2.99).
