Each pack contains two skin on fillet portions Try pan frying it and serving it with some creamy mashed potatoes A 320g pack would serve two average sized main meals Yellowtail is an attractive fish with white flesh and just a touch of oil. Highly prized by the Japanese sashimi trade, it is farmed in Australia and one or two other countries. We buy large fillets which we cut into thick steaks from the front end and these thinner portions from towards the tail - same fish, same taste, but a little thinner and therefore a little cheaper - which is meaningful at the price level for this fish. Sustainability - Our rating 8/10  Our kingfish comes from a well-managed sea farm in Southern Australia. The farm practises low-density farming and is accredited by the Aquaculture Sustainability Council. The \'Good Fish Guide\' recognises this fish as a \'best choice\' seafood.
