Effects of two temperatures on the oxygen consumption rates of Seriolella violacea (palm fish) juveniles under rearing conditions
چکیده انگلیسی

Oxygen consumption rates (mg O2/kg fish/min; OC) of juvenile palm fish (average weight 420 g) were determined for temperatures of 14 and 18 °C. Three replicates of two tanks rearing fish at a density of 24 kg/m3 were used to measure OC at 34 ppt working as open respirometers in a recirculating system under farm-like conditions. The fish were fed commercial dry pelleted feeds at a ratio of 1% of total biomass. Oxygen consumption rates were determined by mass balance calculations. The OC increased from 1.6 to 2.4 g O2/kg fish/day as temperature increased from 14 to 18 °C. The determination of oxygen consumption by palm fish in farm-like conditions provides valuable information on the oxygen requirement of these fish in an aquacultural setting. This bioengineering information can be used for designing and sizing a rearing facility for the intensive culture of palm fish.


► Oxygen consumption rates were determined for Seriolella violacea under farm-like conditions.
► Maximum oxygen consumption rates were 1.69 and 2.42 mg O2/kg fish/min for 14 and 18 °C, respectively.
► Oxygen consumption rates are a valuable insight for S. violacea under farm conditions.
