Abstract

Giant gourami has become one of the main species being cultured in southeast Asia and is in great demand in the aquaculture industry. The main constraint in giant gourami culture is the source of fry that should be standardized for commercial scale propagation. Assessment of growth performance, survival and body protein of giant gourami larvae fed with different types of live food organisms was conducted to identify the most suitable live food for larval rearing. Growth performance [mean final weight (FW) and length (FL)] of giant gourami larvae was significantly highest in enriched Moina (55.3±0.7mg and 16.27±0.29 mm), followed by unenriched Moina (41.0±0.6 mg and 14.73±0.17 mm), unenriched P. redivivus (31.7±0.3 mg and 10.47±0.35 mm), unenriched Artemia (31.0±0.3 mg and 12.20±0.23 mm), enriched Artemia (31.0±0.3 mg and 13.20±0.61 mm), enriched P. redivivus (31.0±0.3 mg and 10.53±0.75 mm) and mixed-zooplankton (19.7±0.9 mg and 8.87±0.24 mm). Highest mean survival of giant gourami larvae was obtained in enriched Moina (96.95±1.21%) but was not found to be significantly different from unenriched Moina (94.17±0.96%), enriched Artemia (87.78±0.55%) and unenriched Artemia (87.22± 5.30%). The lowest mean survival rate was obtained in Mixed-zooplankton (74.72±1.47%) but was not significantly different from those of unenriched P. redivivus and enriched P. redivivus (77.77± 4.82% and 83.33± 3.47%, respectively).
