Abstract
Macrobrachium species is one of the most abundant and valuable cultured freshwater prawns in the world, serving as a high-value food resource. A study conducted in Petagas River, Sabah aimed to determine the habitat preferences of this freshwater prawn, as suitable habitats play an important role for the survival and growth of each species. Six stations were selected representing different habitats: vegetation or shades, dead logs or tree roots and no shelter, consisting only of mud or sand. Prawns were caught using fish traps equipped with two entrance funnels, left overnight, and retrieved the next day. Data were analyzed using SPSS, involving Kruskal-Wallis and Mann-Whitney U tests. Habitats with the presence of dead logs or tree roots portrayed the highest percentage of adult individuals caught (54.43%), followed by those with vegetation (27.22%), and mud (18.35%). Additionally, sstatistical analyses revealed a significant difference in the number of adult individuals among all stations (Kruskal-Wallis; p < 0.05), except between stations V1 and V2 (Mann-Whitney U-test; p>0.05). This study showed that freshwater prawn, Macrobrachium spp. in Petagas River exhibit a preference for habitats that include dead logs or tree roots serving as shelter over those containing only vegetation and mud or sand.
