Abstract
Egg hatching, and fry growth and survival of the walking catfish, Clarias batrachus (Linnaeus), were investigated
under hatchery conditions in West Java, Indonesia. Spawning was environmentally induced in a specialized
breeding pond. Gravid females utilized nests containing kakaban, a fibrous matting from local palm trees (Arenga
sp.), which facilitated egg collection. Newly hatched fry fed with Artemia nauplii though day 8 (after hatching), an
Artemia/cladoceran mix from days 9 to 16, and cladocerans only from days 17 to 23 resulted in over 90% survival of
young from hatched eggs. Other diets examined (rotifers, cladocerans, ground fish meal, and ground Nile tilapia
flesh) proved inadequate for fry through day 16. Fry reared in hatchery aquaria for 16 days versus 23 days before
introduction into nursery ponds showed no significant differences in mean length, mean weight, or percent survival
when harvested at day 58. Suggested guidelines are given for hatchery production of C. batrachus fry and
fingerlings.
