Why the Quayside Still Beats the Supermarket Counter

There is a particular pleasure in buying fish within sight of the water it came from. A coastal market — whether it is a handful of stalls beside a harbour wall in Cornwall, a covered market in North Yorkshire, or a Saturday fish sale on a Scottish pier — gives you access to landings that rarely travel inland. You are buying from people who know the grounds, the tides and the skipper, and who can tell you exactly which boat brought in the box you are looking at.

The trick is knowing what to ask and what to look for. Freshness in seafood is not a matter of luck; it is a set of observable facts, and almost all of them are available to you in the first thirty seconds of a conversation.

Ask About Landing Times, Not Just Prices

Landing time is the single most useful piece of information at any market. In most UK ports, day boats land in the early morning and their catch is on ice by mid-morning; larger vessels may be out for a week or more. Neither is automatically better, but you deserve to know which you are buying. Useful questions include:

• When was this landed? "This morning" and "Tuesday" produce very different dinners.
• Was it day-boat or a longer trip? Day-boat fish is often pricier because it is handled in small quantities and iced quickly.
• How was it caught? Line-caught, hand-dived, pot-caught or netted — this changes both quality and impact.
• Has it been frozen? Some fish is frozen at sea and thawed for sale. That is perfectly legal and can be very good, but it should be declared.
• Where is it from? "Local" should mean a named stretch of coast, not simply "British waters".

Ask these cheerfully and without apology. Good fishmongers enjoy the conversation; it is the ones who dodge the question that you should walk past.

Reading the Signs: Fish, Shellfish and Crustaceans

Start with your nose. Fresh seafood smells of cold sea and wet stone. Ammonia, sour milk or a lingering fishmongery whiff means it has been sitting too long. Then use your eyes and hands.

• Whole fish: bright, domed eyes rather than sunken or cloudy ones; gills that are rosy red, not brown or grey; skin that is glossy and tight, with scales that cling; flesh that springs back when pressed.
• Fillets: a clean, translucent cut with no curling edges, no gaping splits and no brown tinge along the belly.
• Mussels and clams: shells should be closed, or close firmly when tapped. Discard any that stay open, and any with cracked shells.
• Oysters: heavy for their size, tightly closed, with clear liquor inside. Native oysters are traditionally best from September to April.
• Scallops: look for "dry" ones — pale, firm and not sitting in milky liquid, which usually means they have been soaked.
• Crabs and lobsters: buy them live and lively, or cooked and bright. A live crab should feel heavy for its size; a cooked lobster tail should curl under, not hang straight.
• Squid and cuttlefish: skin should be speckled and shiny, the flesh firm and pearl-white.

Fishing the Calendar: Seasonal Catches

Eating with the seasons is not a romantic gesture; it is how you get the best quality at the lowest price. A rough guide for UK coasts:

• January to March: native oysters, mussels, scallops, crab, lemon sole and Dover sole, cod and whiting.
• April to June: crab and lobster come into their own, mackerel arrives inshore, and sea trout and early bass show up.
• July to September: mackerel, bass, bream, sardines, pollack, sweet brown shrimp and cuttlefish — the warm-water months.
• October to December: oysters again, mussels, scallops, herring, sprats, hake and cod.

You will notice the shellfish months cluster around the letters R. That old rule still holds reasonably well for native oysters, which spawn in summer and are better left alone then.

Sustainability Without the Sermon

Sustainable buying at a market is mostly about asking, not avoiding. Look for certification labels, and ask whether the catch meets minimum landing sizes and whether undersized fish are being returned. Hand-dived scallops, pot-caught crab and lobster, and hook-and-line mackerel are generally gentler options than dredged or trawled equivalents. Smaller day boats usually burn less fuel and land fresher fish.

Also think about variety. If everyone buys bass and cod, those stocks carry the pressure. Pollack, hake, gurnard, whiting and coley are excellent eating and often cheaper. Buying a mixed box spreads the demand and gives you a more interesting week of cooking.

Getting It Home and Onto the Plate

Bring a cool bag and a couple of ice packs to the market; a warm car boot undoes the fishmonger's good work in twenty minutes. Ask for whole fish to be gutted and scaled, but keep the head and bones if you fancy making stock. Keep shellfish separate from fillets so any drips do not cross-contaminate, and get everything into the fridge as soon as you are home.

Cook fish within a day or two, or freeze it on the day of purchase. Mussels and clams are best eaten within twenty-four hours; live crabs and lobsters should be cooked the same day. And keep it simple: a fillet of just-landed mackerel needs nothing more than salt, a hot pan and a squeeze of lemon. That is the whole point of buying by the coast.
