ADVANCED LARVAE CULTURE OF AMANO SHRIMP Caridina multidentata BY COMBINED FEEDING WITH LIVE ALGAE AND PROBIOTIC BACTERIA

Larval culture of Amano shrimp (Caridina multidentata), a bilateral migration species, has long been a task in the ornamental shrimp business so that the global market demand for this working shrimp still rely upon natural catch.  The experienced data done by this lab for optimal larval culture survivals are around 30 to 50% and 22 to 25 days for post larval metamorphosis at salinity 20‰ and temperature 26c. The results of the first trial, larvae fed Tetraselmis chui (2x10⁵ cells/ml) in combination with three probiotic species at different concentrations, are listed in Table 1. Table 2 illustrates how culture density affects survival and metamorphosed time. Culture of Amano shrimp larvae live T. chui (2x10⁵ cells/ml) in combination of B. subtilis (5x10⁵ cells/ml) at a stocking density of 30 ind./L, salinity 20‰, 26 - 28℃ is recommended.
