摘要: Abstract Our objective was to gain insight into the optimum temperature and ration for growth of age-0 Atlantic sturgeon Acipenser oxyrinchus in culture. We conducted two trials, each 8 weeks. Trial 1 started with 60-g fish, trial 2 0.3-g fish. Water temperatures 15, 17, 19°C were used separately trial. Rations (dry food : wet weight fish) fish 0.5, 1.0, 1.5% biomass per day; rations 3, 5, 7% day. set up three tank replicates, equal biomass, at combination ration. The highest rate (for 0.014/d 15°C ration, although this not significantly different from 17°C or 1.0% 0.067/d 7.0% Instantaneous these conditions all other combinations temp...
