Nguyen Hoang Sang, Bui Minh Tam

Abstract: This research was carried out to examine morphological changes and the feeding behavior of peacock eel (Macrognathus siamensis) at the larval stage. Fish was stocked in nylon lining tank 10 m2 at a density of 300 fish/m2. Water supply from natural pond was fertilized to create natural food. Fish samples were collected daily for analyzing of food composition and quantity beside the observation of morphological changes. The results showed that mouth size of peacock eel larvae was 0.44 0. 05 mm in the third day after hatch (DAH). Peacock eel larvae had carnivorous feeding habit (Li/Lt
