Diopatra claparedii is one of local polychaetes with commercial value as a brood stock
for prawn farming and because of its regenerative capability. However, none initiative
has been done to culture and maintain the species in artificial aquaria for farming
purposes. In this study, effects of salinity and temperature on survival of intact D.
claparedii and its regenerative capability (either anterior and posterior part) in artificial
condition were investigated. All the specimens were placed into treatment containers
with different salinity (16, 23, 30, 37 and 44 ppt) and temperature (23, 25, 28, 31 and
34 °C) for eight weeks. The study revealed specimens that exposed to salinity (23 and
30 ppt) and temperature (28 and 31 ⁰C) showed the highest survival rate and posterior
regeneration process and may suitable for artificial condition.
