Culture Studies With Malaysian Prawn In Unfed Brackish Water Ponds

This study describes culture of Malaysian prawn (Macrobrachium rosenbergii) without feeding in brackish water ponds in Louisiana. Survival and average size increased with decreasing stocking densities. After 163 days, average production in kg/ha for stocking rates of 1.25/m2 , 2.5/m2 and 3.75/m2 was 159, 191 and 218, respectively. Orbit length-total length relationships were determined to be expressed by the linear equation: Orbit length = 1.498 + 0.736 (total length) with both sexes combined. Total length-weight measurements at harvest of both sexes resulted in the curvalinear equation Log Weight = -5.867 + 3.41O(Log Length). Measurements were in millimeters and grams.
