Estimating oxygen consumption of rainbow trout (Oncorhynchus mykiss) in a raceway: A Precision Fish Farming approach

• Precision Fish Farming can be implemented in raceway trout farms. Real time monitoring of fish weight distribution set up using Biomass Daily system. oxygen demand estimated and predicted a dynamic model, based on water temperature biomass. Oxygen control improved an analytical interpretation demand. The (PFF) approach was applied to the estimation consumption rainbow farm. A simulating evolution Dissolved concentration, identified: daily oscillation rate simulated by means sinusoidal function. model data collected during four-week field study, which carried out July 2019. Water concentration were measured with hourly frequency farm influent effluent. biomass monitored basis combining provided state-of-the art system for non-invasive mortality counting. period partitioned into two time-windows, as not fed first weeks. These windows further calibration validation set. Three parameters, i.e. average respiration rate, amplitude its oscillation, phase fitting output series DO results show that: 1) is consistent literature; 2) when regularly more than twice that fasting fish. suggest could used implement cost-effective automatic supply, short-term prediction
