Frequently Asked Questions About Large fish
Is large fish high in mercury?
Some large fish can be high in mercury, but the species matters more than size alone. Long-lived predators such as swordfish, shark, and some tuna can accumulate more mercury, so identify the fish rather than relying on the label “large fish.”
What counts as a large fish?
Large fish is a size description, not one specific species. It may refer to fish such as tuna, swordfish, salmon, or grouper, depending on the shop and region; ask which species you are buying because cooking and safety advice can differ.
Can you eat large fish during pregnancy?
Yes, but choose the species carefully. Avoid fish known to be high in mercury, such as shark and swordfish, and follow current pregnancy guidance for local fish and tuna varieties.
How do you cook large fish without drying it out?
Cook large fish gently and stop as soon as the flesh turns opaque and separates easily. Thick pieces work well baked or grilled; brushing them lightly with oil and keeping the skin on can help retain moisture.
How can you tell if large fish is fresh?
Fresh large fish should smell mild, not sour or ammonia-like, and its flesh should feel firm. Whole fish should have clear eyes and moist, bright skin; avoid fish with a strong unpleasant odor or soft, dull flesh.
Can large fish be frozen?
Yes, large fish freezes well when wrapped airtight to prevent freezer burn. Portion it before freezing so you only thaw what you need, and thaw it in the refrigerator rather than leaving it at room temperature.
How long does large fish last in the fridge?
Keep raw large fish covered in the coldest part of the refrigerator and cook it as soon as possible after purchase. If it has been left warm, smells off, or feels unusually soft, discard it rather than tasting it.
Should you wash large fish before cooking it?
No, rinsing large fish can spread bacteria around the sink and nearby surfaces through splashes. Pat it dry with paper towels instead, then wash your hands and clean any board or knife that touched the raw fish.
Does large fish have a lot of bones?
It depends on the species and cut: a large fish steak may contain a central bone, while a properly cut fillet has fewer bones. Check the flesh carefully before serving, especially when preparing a meal for children.
Can you eat large fish raw?
Only eat large fish raw when it has been handled and prepared for raw consumption by a reliable supplier. Cooking reduces the risk from parasites and harmful microbes, so do not eat raw fish if its species or storage history is uncertain.

What is Large fish?
Large fish refers to a broad group rather than one particular species. Its flesh can be lean or richer depending on the fish, but it is generally valued as a source of protein; oily species also provide omega-3 fats. In many coastal cuisines, larger fish are served as steaks or cooked whole, while boneless portions are convenient for everyday meals.
Grilling, baking and pan-cooking all suit it, with lemon, herbs and vegetables as simple accompaniments. The flavour and texture vary by species, from mild and firm to more delicate and oily. At 22 g of protein and 0 g of carbohydrate per 100 g, it can fit well into a low-carb meal. For a lighter plate, bake or grill it rather than deep-frying.
