In this paper, we cover 4 years of live fish transports that ranged from 14 to 200 h (8 days), and bioloads from 3.8 to 76.9 kg/m3. The key ingredients for success in all trips, where virtually no mortality occurred, was atributed to (1) pre‐buffering the water with sodium bicarbonate and sodium carbonate at 50 g/m3 (each)—and/or ATM Alka‐HaulTM at 25 g/m3—and applying additional (partial or full) doses throughout each transport, whenever the tanks were accessible; (2) pre‐quenching ammonia with ATM TriageTM at 32 g/m3, and applying additional (partial or full) doses throughout each transport, whenever the tanks were accessible; (3) keeping the dissolved oxygen saturation rate above 100%, ideally above 150%; (4) Keeping temperature on the lower limit of each species' tolerance range; (5) Using foam fractionators to effectively eliminate organic matter from the water and (6) Using pure sine wave inverters, which allows for a steady supply of electrical current throughout the transport. The use of a ‘preventive’ versus ‘corrective’ pH buffering philosophy is also discussed.
