How to Buy Fresh Fish in the Philippines or Abroad

A cold-chain-first fish-buying guide covering smell, eyes, gills, flesh, labels, previously frozen seafood, species substitution and safe transport.

In this article

A good fish purchase begins with temperature, seller hygiene and honest labelling, then uses smell, texture, eyes and gills as supporting evidence. The same principles apply in a Philippine wet market, supermarket or overseas fish counter, although the display style and species names may differ. Philippine postharvest guidance likewise treats correct handling as essential to preserving fish quality and reducing losses. Source 3

Fresh-fish buying checklist
CheckGood signReject or question
TemperatureRefrigerated or surrounded by clean fresh ice in a protected displayWarm fish, melted dirty water or repeated exposure to sun.
SmellFresh and mild, sea-like but not pungentSour, rancid, strongly fishy or ammonia-like odour.
Whole-fish eyesClear and shiny for fish sold as fresh, acknowledging species differencesCloudy, sunken or dried eyes together with other spoilage signs.
GillsRed and without offensive odour in genuinely fresh whole fishBrown-grey slime or strong odour.
FleshFirm and springing back when pressedSoft flesh that keeps a dent, drying or dark edges.
FilletsMoist firm flesh and clean edgesDiscolouration, gaping, drying, excessive drip or off odour.
LabelSpecies, origin, fresh/previously frozen status and use-by information where requiredVague substitute name, missing required information or seller unable to explain the product.

Previously frozen is not automatically inferior

Fish frozen promptly and handled well can be excellent, especially far from the coast. The U.S. FDA notes that previously frozen fish may not have the bright eyes, red gills or firm characteristics of never-frozen fish, but should still smell fresh and mild rather than sour, rancid or ammonia-like. Judge it according to its actual handling history, not a romantic assumption that “fresh” always means better. Source 1

Species names and substitution

  • Ask for both the local market name and, where practical, the English or scientific name.
  • When buying abroad, “milkfish,” “mackerel,” “sea bream” and “snapper” may cover different species than a familiar Philippine market name.
  • Choose by cooking properties as well as name: oiliness, bone structure, skin strength and fillet thickness affect the recipe.
  • Do not substitute raw fish into kinilaw solely because it looks fresh; parasite and pathogen risks depend on species, source and freezing controls.
  • For a diner with fish allergy, follow their established avoidance plan and their allergist’s advice. Do not substitute another fish species as a kitchen experiment; retain labels and check cross-contact as well as species identity.

Transport and home storage

  • Buy fish near the end of the shopping trip.
  • Use an insulated bag with ice packs for a long journey.
  • Refrigerate at 4°C or colder as soon as possible.
  • Use refrigerated seafood within two days or freeze it, following FDA guidance and product labels.
  • Thaw in the refrigerator; for rapid thawing, seal in a bag and use cold water, then cook immediately.
  • Keep raw seafood and its juices away from ready-to-eat food.

Cooking endpoint

FDA guidance gives 63°C or 145°F as the general internal temperature for seafood. Without a thermometer, fish should become opaque and separate easily with a fork. Thin fish can overshoot quickly, so use the thickest part as the check and remove it from heat when safely done. Source 1

A market question set

  1. What species is this?
  2. Was it previously frozen?
  3. When did it arrive?
  4. Has it stayed on ice or under refrigeration?
  5. Can it be cleaned or cut while I watch?
  6. What cooking method does this size suit?

The buying decision

Choose the cold, mild-smelling, firm fish from a seller who can identify it and explain its handling. A familiar name cannot compensate for poor temperature control, and a less familiar species can be an excellent substitute when its texture, bones and cooking method are understood.
