This can range anywhere from several days to several weeks—and the fish must be cooked immediately after purchasing. Cook any fresh fish as soon as possible. This preserves the fish at their peak freshness and also kills any bacteria or parasites, resulting in a safer and fresher product. If a fish is flash frozen, stored and distributed correctly, you should notice little difference with fish that is fresh.
Frozen fish dramatically reduce carbon emission from air transport and waste. Heat a tablespoon of butter and a tablespoon of olive oil in a large pan. Monkfish Fillets. Brill Fillets.

But you can help change this. Consumer demand for sustainable seafood can act as an extremely powerful incentive for better fisheries management. If you buy, or ask for, seafood that comes from sustainable sources you are helping to protect our marine environment and, at the same time, ensuring that seafood can be enjoyed for many years to come.
Ask your supermarket, fish store, or favourite restaurant to stock MSC-certified fish. Check out the WWF seafood guides They still need to be fed wild fish, though. Eating vegetarian fish such as tilapia removes this issue. The most sustainable method of catch is through pot or creel, as this selects larger crabs and has minimal impact on the surrounding envrionment. Alternatively, get your omega-3 by eating what the salmon eats. Oily fish like herring, anchovy and sardines are high in micronutrients.
Farmed prawns were historically associated with the destruction of mangrove forests. Studies have indicated mangrove forests can store four times as much carbon as tropical forests. Like salmon, prawns require fish protein in their feed and a proportion of this comes from wild-caught fish.
Shrimp farms have also been associated with human rights abuses. Part of the ASC standards include farms demonstrating they are treating workers fairly. The best bet is to avoid warm-water prawns, opting instead for cold-water, wild-caught, MSC-certified prawns, typically from the waters between Canada and Norway. They are also harvested by bottom trawling, but in areas of muddy sediment, where the lasting environmental impact is lessened and bycatch is less of an issue. Rope farmed mussels have some seriously impressive sustainability credentials — they take their nutrients from the sea water and, at the same time, filter and clean it, actively sequester carbon into their shells, and are full of micronutrients and high levels of Omega Rope farming means harvesting them does no damage to the sea bed.
Some tuna is more sustainable than others. Skipjack and Albacore are usually the best choices but it does depend on fishing methods. Some brands and supermarkets will clearly label their tuna as caught by pole and line - this and troll fishing another type of line fishing are generally viewed as the most sustainable. Avoid tuna caught by gillnet as these nets can be up to 7km long and have high levels of bycatch. Most Pacific or Southern Bluefin tuna stocks are at critical levels.
UK mackerel is a good nutritional substitute when fished locally. All mackerel in the northeast Atlantic lost MSC certification in after stocks dropped below a precautionary level and country catch quotas were deemed too high. But UK mackerel, mainly from Cornwall, by boats using handlines is a good choice.
Sardines , another oily fish high in Omega-3, can also be fished locally. There are some good white fish alternatives that you can look out for. Hake can be fished sustainably from the UK.
Coley from Iceland and the North-East Arctic is also a good choice, and is often cheap to buy. Pollock sustainability varies, but there are some good choices from Alaska and parts of Russia. Or try haddock.
