Resources use is one area of concern in fish culture. The study assessed input/output data of 5 fish farms and 8 hatcheries using life cycle analysis comparing CO2 emissions (CO2e/kg fish), energy consumption (MJ/kg fish) and water use (L/kg fish) in fish production within farms and against published data for chicken, beef and pork. Results of CO2 emissions and energy consumption of 5 fish farms showed Cobia cage farm highest at 8 kg CO2e/kg fish and 123 MJ/kg fish while Asian sea bass recirculation aquaculture systems (RAS) farm lowest at 1.7 kg CO2e/kg fish and 21 MJ/kg fish. High CO2 emissions and energy intake of Cobia farm were attributed to feed delivery from a distance of 5,600 km. Feed to Asian sea bass farm came from 880 km. Feed sourcing was a factor for CO2 emissions and energy use. Among three RAS farms, tilapia had the highest water use at 403 L/kg and Sea bream the lowest at 39 L/kg. Study findings comparing fish with chicken, beef and pork on CO2 emissions showed...
