Developments of Digestive Tract in Larvae of Climbing Perch, Anabas testudineus (Bloch), (Indonesian Aquaculture Journal Vol.5 No.2, 2010)

Climbing perch, Anabas testudineus (Bloch) is a potential species for aquaculture in Kalimantan, Indonesia and belongs to Anabantidae family. The development of its digestive tract was evaluated on larvae reared under culture conditions of 28 o C- 30 o C, from hatching to 30 days after hatching using histological and morphological methods. The larvae were kept in six 100-L tanks. They were fed with rotifers and microalgae from day 2 nd after hatching to day 10 th ; Artemia nauplii from day 7 th to day 15 th ; Artemia meta-nauplii from day 15 th to day 20 th ; and Tubifex worm from day 20 th onwards. The development of digestive tract in climbing perch followed the general pattern described for other species. Shortly after hatching, its digestive system was found to be consisted of an undifferentiated straight tube laying dorsally to the yolk sac. At first feeding (day 2 nd ), both mouth and anus had opened and the yolk sac was partially absorbed. On day 3, the digestive tract was fully differentiated into buccopharynx, esophagus, intestine and rectum. The two pyloric caeca appeared
on day 25 th after hatching, indicating the transition from larval to juvenile stage and acquisition of an adult type of digestion.
