Soak the fish in salted water with a few crushed garlic cloves for 4-5 hours. The water to salt ratio should be 5:1. Each sturgeon should weigh approximately 1kg.
Rinse the fish, pat it dry, and let it air dry for an hour.
Prepare the Kamado BONO grill for indirect cooking. Light the charcoal with a fire starter and wait until the temperature reaches 80°C. Add smoking wood chips. Adjust the top and bottom air vents to maintain a consistent temperature. Place the sturgeon on the grill grates and smoke for 3.5-4 hours until the internal temperature reaches 63°C.
