Product details

Frozen chub mackerel is a widely available, hassle-free seafood staple sold at nearly all supermarkets and seafood retailers.

Instead of being frozen together in one solid slab like conventional block-packed mackerel, each IQF mackerel is separately snap-frozen immediately after harvesting.

This ultra-fast freezing method preserves the fish's natural freshness, original taste and firm texture perfectly, delivering a flavor experience nearly identical to freshly caught mackerel once prepared.

It's an ideal pick for busy households, home chefs, and anyone looking for a nutrient-dense meal-without the trouble of fresh mackerel's short shelf life and easy spoilage.

FAQ

01.What exactly is chub mackerel, and how is it different from Atlantic mackerel?

Chub mackerel (scientific name: Scomber japonicus) is a related species to Atlantic mackerel (Scomber scombrus), found in warmer waters across the Pacific and other parts of the world. Visually, Atlantic mackerel have bold, tiger‑like stripes with a clean silver belly, while Pacific chub mackerel have faint dark spots below the lateral line. Atlantic mackerel have richer fat content (up to 25% lipid) and are preferred for smoking or grilling, whereas Pacific chub mackerel offers a steadier, leaner supply ideal for canning, breaded portions, and value‑channel products. Chub mackerel also has a swimbladder, while Atlantic mackerel does not.

02.How should frozen chub mackerel be stored, and how long does it last?

Frozen chub mackerel should be kept at -18°C (0°F) or below. Commercially, it has a shelf life of up to 24 months. However, quality depends heavily on storage temperature: storage at -30°C can maintain quality for at least 9–12 months, while temperatures above -20°C accelerate lipid oxidation and quality loss. Because chub mackerel is a fatty fish with highly unsaturated lipids, it is very susceptible to quality loss from lipid oxidation during frozen storage. To prevent freezer burn, it should be glazed and packed in moisture‑proof packaging.

03.What is the best way to thaw frozen chub mackerel?

The safest method is slow thawing in the refrigerator overnight (about 1 hour for smaller portions). For rapid thawing, a subzero temperature treatment at -2°C for 3 hours prior to thawing can prevent "thaw rigor"-a condition that causes muscle contraction and drip loss-while preserving high ATP content for sashimi‑quality meat. Never thaw at room temperature, as this promotes bacterial growth and accelerates lipid oxidation. Once thawed, consume within 1–2 days and do not refreeze.

04.What are the best ways to cook frozen chub mackerel?

Chub mackerel has red, oily flesh with a rich and strong flavour. It is highly versatile and can be:

Grilled over medium‑high heat for 4–5 minutes per side, which adds a smoky flavour

Smoked – its high oil content makes it ideal for smoking

Fried, steamed, boiled, or baked

Sear fillets quickly to crisp the skin while keeping the inside slightly cooked-ideal for sashimi
It is especially popular grilled in Thai cuisine. Chub mackerel can also be used as bait for catching tuna and other large fish.

05.Is frozen chub mackerel nutritious and sustainable?

Nutrition: Chub mackerel is highly nutritious. It is rich in iron, calcium, protein, phosphorus, sodium, potassium, niacin, vitamins B and D, and unsaturated fatty acids EPA and DHA. These omega‑3 fatty acids support heart health, reduce blood fat and cholesterol, and may help prevent cardiovascular disease and certain cancers. However, omega‑3 concentrations can decrease during cold storage.
