Ingredients & Substitutions
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
| Check | Good sign | Reject or question |
|---|---|---|
| Temperature | Refrigerated or surrounded by clean fresh ice in a protected display | Warm fish, melted dirty water or repeated exposure to sun. |
| Smell | Fresh and mild, sea-like but not pungent | Sour, rancid, strongly fishy or ammonia-like odour. |
| Whole-fish eyes | Clear and shiny for fish sold as fresh, acknowledging species differences | Cloudy, sunken or dried eyes together with other spoilage signs. |
| Gills | Red and without offensive odour in genuinely fresh whole fish | Brown-grey slime or strong odour. |
| Flesh | Firm and springing back when pressed | Soft flesh that keeps a dent, drying or dark edges. |
| Fillets | Moist firm flesh and clean edges | Discolouration, gaping, drying, excessive drip or off odour. |
| Label | Species, origin, fresh/previously frozen status and use-by information where required | Vague 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.
Match fish to Filipino cooking
| Method | Useful traits | Examples | Buying priority |
|---|---|---|---|
| Grilling | Firm flesh, intact skin and enough fat to resist drying | Whole bangus, pompano, tuna jaw or sturdy fillets | Even size and clean gut cavity. |
| Frying | Moderate-sized whole fish or firm steaks that cook evenly | Tilapia and galunggong | Dry surface, intact skin and no belly spoilage. |
| Paksiw | Fish that holds shape in acidic simmering | Bangus and other firm fish | Fresh mild smell and pieces of even thickness. |
| Sinigang | Fish with enough structure for broth cooking | Bangus belly, salmon head or firm local fish | Bones and head clean; gills removed when appropriate. |
| Kinilaw | Very high-quality fish specifically suitable for raw preparation | Tanigue or another validated species from a trusted supplier | Documented handling and freezing controls, not appearance alone. |
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
- What species is this?
- Was it previously frozen?
- When did it arrive?
- Has it stayed on ice or under refrigeration?
- Can it be cleaned or cut while I watch?
- 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.
