“…Oxygen consumption per unit of time is another crucial factor in the determination of metabolic rate, and is a critical concern in crustacean culture (Carvalho and Phan 1997;Taylor et al 2002;Niu et al 2003;Daoud et al 2007). In aquaculture, the maintenance of a suitable oxygen concentration ultimately depends on artificial aeration and good management of the oxygen consumption or production on the part of the biomass (Culberson and Piedrahita 1996;Gillooly et al 2001;Coyle et al 2005). At low levels of dissolved oxygen, prawns become stressed and frequently reduce their feeding rate (Niu et al 2003).…”

Oxygen Consumption of the Prawn Macrobrachium americanum over the Temperature Range of its Native Environment and in Relation to its Weight

Cauque prawns Macrobrachium americanum of four different weights were tested at different temperatures to determine the differences in their oxygen consumption. The prawns were studied in a closed respirometer system in individual assays of 30 min each. Temperature (18–30°C) had a noticeable effect on oxygen consumption for all weights of prawns; weight had a less significant effect. In all cases, the mass‐specific oxygen consumption rate of small prawns was higher than that of large prawns for all of the temperatures studied.

“…Increases in transport temperatures significantly increase oxygen consumption and nitrogenous excretion (Chen and Kou 1996), thereby reducing acceptable biomass densities or transport times. Harrison and Lutz (1980) reported that the survival of juvenile prawns increased when transported at a reduced water temperature (208C). The water temperature in this study increased from 218C to 248C over the duration of the experiment.…”

During the stocking of grow-out ponds, juvenile prawns are usually transported from regional nurseries by truck in vented tanks. Hauling stress and associated delayed mortality have been implicated as potential causes of low pond survival. An experiment was conducted to evaluate the effects of biomass density, substrate, and salinity on water quality and transport survival of juvenile freshwater prawns Macrobrachium rosenbergii. The trial was designed as a 3 3 2 3 2 factorial and evaluated three biomass densities (10, 20, and 30 g/L), the presence or absence of added substrate (plastic mesh to provide a 200% increase in surface area), and the presence or absence of added salt (0% or 6%). Model transport tanks were 15-L, open styrofoam containers aerated with pure oxygen and compressed air. Water quality analyses were performed prior to stocking. After 24 h, water quality analyses were again conducted and all prawns were removed, designated as alive or dead, weighed, and counted. After 24 h of simulated transport, three-way analysis of variance indicated no significant interactions (P . 0.05) between the main effects of density, substrate, or salinity for prawn survival or water quality. When the main effects were analyzed separately, survival was significantly influenced by density. Survival was significantly lower (P , 0.05) in the highdensity treatment (30 g/L: 89% survival) than in the medium-(20-g/L) and low-density (10-g/L) treatments, which were not significantly different (P . 0.05) and averaged 95% survival overall. Total ammonia nitrogen and un-ionized ammonia nitrogen concentrations significantly increased (P , 0.05) as biomass density increased. The addition of salt to the transport water did not significantly affect survival (P . 0.05) but did result in a significant decrease (P , 0.05) in both pH and un-ionized ammonia nitrogen. Added substrate had no significant (P . 0.05) impact on any measured variable. These data indicate that good survival can be achieved at a biomass density of 20 g/L and that increased salinity appears to reduce the buildup of toxic metabolites. The addition of substrate to the transport tank appears to provide no benefit.
