This current study focuses on the parasites infesting the M. rosenbergii and the correlation with the body size of the prawns obtained from Sarawak, precisely from the Kuching-Samarahan region. A total of 72 samples were dissected and processed in the lab to analyse their body length, weight and for the presence of parasites. Results found that eleven individuals were infesting about 15% (11 out of 72) of the samples which were identified as Probopyrus sp., Calanus sp., Nematode, and an unknown larva. The highest prevalence among these parasites is from Probopyrus sp. (6.94%), followed by Nematode (4.17%), Calanus sp. (2.78%), and unknown larva (1.39%). Majority of the infected prawns were categorised under the 111 - 120 mm interval, which is the shortest length group with an average weight of 17.91 g and none were infected from the bigger sizes prawns. The correlations between the parasite mean intensity and the prawn length (mm) were found to be negative for all of the parasites mentioned; Probopyrus sp. (r = - 0.725), Calanus sp. (r= -0.518), nematode (r= -0.646) and the unknown larva (r= -0.137).
