Grey Mackerel

Scomberomorus semifasciatus

Grey Mackerel



Available wild-caught, it is a marine fish found in open waters and near reefs over the continental shelf around the northern half of Australia from Port Macquarie (NSW) to Shark Bay (WA). It’s caught off Queensland by surround nets, gillnets and trolling as well as off the NT and WA.

Juveniles are found in estuaries and near the coast and caught in nets or on lines. It has dark vertical stripes on its side similar to Spanish Mackerel, especially when young, but once the fish is caught these fade quickly to a silvery-grey.

To Buy

Sold mainly as cutlets and steaks. In cutlets and steaks look for bright pinkish-red, firm, lustrous, moist flesh without any dark brown markings or oozing water and with a pleasant fresh sea smell.

To Store

Make sure whole fish is scaled, gutted and cleaned thoroughly. Wrap whole fish, fillets and cutlets in plastic wrap or place in an airtight container. Refrigerate for up to 2 days (it is best eaten as fresh as possible) or freeze for up to 3 months below -18ºC.

To Cook

Average yield is 40%. Has a strong, distinctly ‘fishy’ flavour, medium to very high oiliness and medium-dry, firm flesh. Usually sold skinned, it has few bones, which are easily removed. Score thick fillets at the thickest part of the flesh to allow even heat penetration.

Cooking Methods

Pan-fry, bake, grill, barbecue, smoke, pickle.

Goes Well With

Strong flavours, bay, basil, citrus, curry, garlic, mustard, onion, oregano, pepper, red wine, tomatoes, vinegar.
