Sustainable Seafood in Hong Kong: What to Order and Why It Matters

Hong Kong is one of the world's great seafood cities. The evening wet markets, the dai pai dongs serving steamed fish with ginger and spring onion, the Cantonese ritual of choosing your meal live from a tank — seafood is woven into the fabric of daily life here in a way that's hard to overstate.

But there's a number attached to that love affair that's worth sitting with: 65 kilograms. That's how much seafood the average Hong Kong resident consumes every year — more than three times the global average of 20 kilograms, enough to make Hong Kong the eighth-largest seafood-consuming city in the world.

The question that follows is uncomfortable but necessary: where is all that fish actually coming from, and is there enough of it left?

The overfishing problem in plain numbers

The short version is sobering. Seafood resources in the South China Sea have fallen by 70–95% compared to the 1950s. That's not a gradual decline — it's a collapse. Local fisheries that once supplied wet markets across Kowloon and Hong Kong Island have essentially ceased to function at commercial scale.

More than 90% of the seafood consumed in Hong Kong is now imported from over 170 countries and territories. That supply chain is vast, complex, and in many cases poorly regulated. Illegal, unreported, and unregulated (IUU) fishing — the industry's polite term for fish theft — accounts for an estimated 20% of global seafood catch. There's a meaningful chance that the fish on your plate right now was caught in ways that violate environmental agreements, labour standards, or both.

What "sustainable seafood" actually means

The phrase has become a marketing buzzword, which makes it worth unpinning. Sustainable seafood generally means fish or shellfish that:

• Is caught or farmed in ways that maintain healthy population levels and don't destroy marine habitat

• Comes from traceable supply chains where you can verify the catch method and origin

• Is certified by a recognised third party — the Marine Stewardship Council (MSC) and Aquaculture Stewardship Council (ASC) are the most globally recognised; Ocean Park Hong Kong publishes its own Hong Kong-specific Sustainable Seafood Guide

None of those certifications are guarantees. But they're meaningful signals in a market where "fresh from the ocean" tells you almost nothing.

What the options look like in Hong Kong right now

Here's the honest reality: sustainable seafood remains a niche offering in this city. A 2026 study surveying 18 supermarkets and over 400 consumers found that sustainable seafood availability in Hong Kong is highly polarised— largely confined to premium supermarkets and high-end restaurants, with almost no presence in wet markets or casual dining.

Of more than 20,000 food outlets surveyed by the Hong Kong Sustainable Seafood Coalition, only 7% offered at least one sustainable seafood item. Ecolabels — the MSC blue fish tick, the ASC teal circle — are rarely spotted outside City Super, Park n Shop's premium range, or a handful of specialty grocers in Mid-Levels and Sai Ying Pun.

That's both a problem and an opportunity. Any restaurant, wet market stall, or supplier who makes even a modest commitment to better sourcing immediately stands out from 93% of the competition.

Where to find better options right now

A handful of organisations and venues are doing the legwork for consumers who want to make smarter choices.

WWF Hong Kong's Seafood Guide is the most practical tool available. It rates common species as "best choice," "acceptable," or "avoid" based on current stock health and catch method, and is updated as conditions change. The guide is freely searchable at wwf.org.hk.

Ocean Park Hong Kong's Sustainable Seafood Guide covers species-specific advice and is particularly strong on Cantonese staples — grouper, snapper, sea bass — that appear most often on local menus but are often sourced from heavily exploited stocks.

The Hong Kong Sustainable Seafood Coalition is an industry body working with importers, restaurants, and retailers to shift sourcing standards across the sector. Members include some of the city's larger hotel groups and food service operators.

On the restaurant side, a growing cluster of venues across Central, Sai Ying Pun, and Kennedy Town are making credible sustainability commitments — typically independent or chef-led restaurants with more control over their supply chains.

Three practical shifts that actually make a difference

1. Eat further down the food chain. Small, fast-reproducing species — sardines, mackerel, anchovies, squid, mussels — are almost universally more sustainable than large predator fish like grouper, tuna, and swordfish. They're also cheaper, higher in omega-3s, and better suited to many Cantonese cooking methods. The tradition of embracing whole small fish is actually a sustainability strength hiding in plain sight.

2. Ask one question. "Where is this from?" is the most powerful thing a consumer can say to a restaurant or wet market vendor. You won't always get a useful answer — but asking creates pressure. Vendors who get asked frequently start to find out. Restaurants whose sourcing is questioned start to think about their answers before they're asked. This is how norms shift.

3. Be flexible about species. Most unsustainable choices happen because people have a fixed picture of what a "good" fish dinner looks like. Barramundi instead of sea bass. Farmed oysters instead of wild-caught scallops. Mussels instead of tiger prawns. Canned sardines instead of fresh tuna. The protein quality is comparable. The environmental footprint is not.

The surplus angle: what CHOMP sees in the field

One pattern CHOMP encounters regularly: sustainable and premium seafood — the fish that costs more to source responsibly — ends up as food waste at a disproportionately high rate. When a restaurant has invested in MSC-certified salmon or line-caught kingfish and doesn't sell through during service, that's expensive waste.

Food rescue captures exactly that moment. A portion of well-sourced fish that would otherwise be thrown out at 10pm becomes a meaningful meal for someone nearby at a price that works for both sides. Better sourcing and less food waste reinforce each other — they're the same commitment, expressed at different points in the supply chain.

Some of the most striking Rescued Feast menus have been built around exactly this combination: surplus sustainable seafood from CHOMP partner restaurants, cooked into something worth sitting down for.

What's shifting in 2026

Consumer awareness in Hong Kong is moving. A 2026 MDPI study found that willingness to pay a premium for certified sustainable seafood was higher than expected among urban, younger-skewing consumers. Government procurement guidelines are increasingly incorporating sustainability language. And a growing number of hotel groups and corporate caterers are signing up to the Sustainable Seafood Coalition's commitments, which creates downstream pressure on their suppliers.

The change is slow. But the direction is right — and every purchasing decision that signals demand for traceable, responsibly sourced fish moves it a little further.

If you'd like to experience sustainable seafood in a different context, our upcoming Rescued Feast dinners occasionally feature menus built around responsibly sourced surplus fish from CHOMP partner restaurants. Every dish is made from rescued ingredients; every ticket is one less portion headed to landfill.

Taste the difference responsible sourcing makes.

Our Rescued Feast dinners sometimes feature surplus sustainable seafood from CHOMP partners — responsibly sourced, rescued from waste, cooked by people who care. Sign up and we'll tell you when the next one is on.
