Abstract

Macrobrachium pilimanus and M. sintangense are two indigenous species of freshwater prawn in Indonesia that have good prospects in freshwater aquaculture. This study aimed to determine the daily activity patterns of circadian rhythm related to differences in periods (night and day phase) and sex in passive-active behavior from two species of freshwater prawns, M. pilimanus and M. sintangense. The behavioral observation was conducted using the scan sampling method on three individuals from each species during night and day periods for 60-minutes. The results showed that M. pilimanus and M. sintangense have the highest percentage of passive behavior (04.00–07.00 PM), i.e., hiding and partially inactive. Sex and time (night and day) played an essential role in the behavioral frequencies of both species. This finding indicates that shelter for hiding is vital for both freshwater prawn species as a strategy to increase productivity and animal welfare.
