This study was aimed to clarify the kind of suitable feeds and nursing environment for each development stage of red clawed crab larvae. The study included two experiments of six treatments, of which, the experiment one is on nursing the larvae from Zoea-1 to Zoea-4 with feeding A (Artemia at umbrella stage + Frippak-150 for Zoea-1 to Zoea-2 and Nauplii Artemia + Frippak-150 for Zoea-3 to Zoea-4), B (Rotifer for Zoea-1 to Zoea-2 and Nauplii Artemia for Zoea-3-Zoea-4) and C (Rotifer + umbrella stage Artemia for Zoea-1 to Zoea-2 and Nauplii Artemia + Frippak-150 for Zoea-3 to Zoea-4), the second is on nursing larvae from Zoea-4 to crab-1 with feeding D (Nauplii Artemia + Frippak-150 for Zoea-4 to crab-1), E (Nauplii Artemia for Zoea-4 to crab-1) and F (Nauplii Artemia + Lansy-PL for Zoea-4 to crab-1); and both experiments in green and clear water systems. Results showed that nursing in green or clear water systems did not affect the growth and survival rate of red clawed crab. Nursing red clawed crab from Zoea-1 to Zoea-4 and feeding C feed; and nursing from Zoea-4 to crab-1 with D feed resulted the best in term of the growth, survival rate and crab-1 production (p
