Macrobrachium rosenbergii is becoming an increasingly key value species, as it is
considered to have the potential to raise the incomes among farmers. Thus, the
objective of this study is to compare and assess the nutritional composition of various
commercial pellets used in grow-out farming and to identify the optimal culture model
for Macrobrachium rosenbergii in Malaysia. Various commercial pellets were collected
from the local market supplier and farmers from Terengganu, Kelantan, Pahang,
Perak, Kedah and Johor. These pellets were analysed to identify and compare their
proximate analysis composition in moisture, ash, lipid and protein. The water stability
of the pellets were also analysed. Each pellets test run consisted of 2 g of pellets that
were dried at 105ºC for 30 minutes, followed by three interval of drying at 65°C (10,
20, and 30 min). In addition, a survey was conducted where a total of three
questionnaires were distributed to farmers of grow out ponds of giant freshwater
prawn at Terengganu, Kedah and Johor. Pellets from KED showed the best water
stability. Significant diffrences of moisture, ash, lipid and protein content were
observed in the various commercial pellets collected and there were differences in
harvesting size due to the cultured period and method applied. The lowest feed
conversion ratio (FCR) were found to be from farmers from JHR. By referring to the
data obtained, the optimal commercial pellet and culture model for better efficiency
and management can be adopted to reduce feed cost and at the same time increase
productivity.
