You walk into a classic British chippy, the air thick with the scent of frying oil and malt vinegar. The menu board lists the usual suspects: cod, haddock, plaice, maybe rock. But then your eye catches something different. "Perch." It sounds rustic, authentic, maybe even a bit adventurous. Is perch used for fish and chips? The short answer is yes, but it's the exception, not the rule. It's the craft beer in a world of mass-market lager. Let's unpack why.

The Traditionalist's View: Why Cod and Haddock Rule
Think of fish and chips as a perfect, greasy symphony. Every element has a role. The fish needs to be a specific type of performer.
Cod and haddock from the cold North Atlantic have dense, large-flaked, meaty flesh. It holds together under the intense heat of the fryer. The batter gets crispy, the inside stays moist and firm, and you get that satisfying pull when you break it apart with a fork. This structural integrity is non-negotiable for a busy chip shop serving hundreds of portions a night. Consistency is king.
Perch, on the other hand, is a freshwater fish. Its flesh is softer, flakier in a more delicate way. I've seen batches where the fish almost disintegrates inside a heavy batter jacket if the fry cook's timing is off by 30 seconds. It's less forgiving.
The Core Issue: It’s not really about taste. It’s about physics and logistics. A high-volume kitchen needs a fish that can survive the journey from fryer basket to paper to customer’s hand, sometimes after a 10-minute walk home. Perch can be a fragile cargo.
Perch on the Plate: Taste, Texture, and the Frying Test
So what happens when you do fry perch?
The flavour is distinct. It's sweeter and has a more pronounced "freshwater fish" character compared to the clean, mild, oceanic blank canvas of cod. Some people call it "fishier," which isn't always a bad thing if you love that taste. The texture, when cooked perfectly, is tender and flaky—but it's a fine, soft flake, not a meaty chunk.
Potential Pros of Perch for Fish & Chips
- Local & Sustainable: In many inland areas, perch can be sourced from local lakes or rivers, reducing food miles. The Marine Conservation Society often lists UK freshwater perch as a more sustainable choice than some North Sea cod stocks.
- Unique Flavour: Offers a break from the predictable. For the adventurous eater, it feels more "authentic" to a specific region.
- Supporting Small Suppliers: Often comes from small-scale fishermen, appealing to the "shop local" ethos.
Common Cons & Practical Hurdles
- Texture Risk: High chance of becoming mushy or falling apart if overcooked, which is easy to do in a fast-paced chippy.
- Size & Yield: Perch are smaller fish. You get less usable fillet per fish compared to a large cod, affecting preparation time and cost.
- Supply Inconsistency: Hard to guarantee a steady, uniform supply year-round for a menu staple. It's often a "when available" special.
- Customer Expectation: Most people walking into a chip shop crave the classic taste and texture. Perch can surprise—and not always pleasantly.
The Hunt: Where You Might Actually Find Perch & Chips
You won't find it at your standard high-street chain like Harry Ramsden's. The hunt is part of the experience.
Focus on inland towns and villages, especially those near sizeable lakes or river systems. Think areas in the Lake District, the Norfolk Broads, or parts of Scotland and Ireland with strong freshwater fishing traditions. Look for the independent, often family-run, shop that's been there for decades. The kind with handwritten specials on a chalkboard.
I remember a specific shop in a market town in Staffordshire, not far from a series of reservoirs. They'd offer perch on Fridays, but only if the local angler had a good week. It was never advertised online. You had to know to ask. That's the typical model.
Some gastropubs with a serious commitment to hyper-local sourcing might also feature it as a premium item on a "posh fish and chips" dish.
Price Check: Is Perch Cheaper or a Premium Choice?
This is where it gets interesting. Logic might suggest a locally caught freshwater fish is cheaper than imported Atlantic cod. Often, the opposite is true.
| Fish Type | Typical Price Point (Relative) | Reasoning | Customer Perception |
|---|---|---|---|
| Cod (Standard) | Base Price | Global commodity, efficient large-scale processing, consistent supply. | Expected, standard, the "default." |
| Haddock | Slightly higher than Cod | Often seen as a premium alternative with finer flavour, especially smoked. | A small upgrade, a classic choice. |
| Perch (when available) | Often highest | Low-volume, artisanal supply, more labour-intensive to fillet, marketed as a specialty. | Niche, gourmet, or "weird." |
| Plaice or Rock | Mid-range | Smaller flatfish, different texture, common alternative. | Alternative for regulars. |
A shop selling perch might charge £1-2 more than their cod portion. They're not competing on price; they're selling a story—locality, rarity, tradition.
The Fry Cook's Secret: What Professionals Won't Tell You
I spoke to a chip shop owner in Yorkshire who occasionally runs perch as a special. His biggest gripe wasn't the cooking; it was the prepping.
"Cod fillets are uniform," he said. "You get a 6-ounce portion, it's a neat rectangle. Perch fillets are all shapes and sizes, some with tricky bones. You spend twice as long prepping a kilo of perch versus a kilo of cod. And then you have to explain to every other customer what it tastes like. It's a passion project, not a money-maker."
This highlights the hidden barrier: labour cost and customer education. The National Federation of Fish Friers provides training on handling standard species. Perch is a masterclass you figure out yourself.
The Texture Trap Most Shops Fall Into
Here's a subtle mistake: treating perch with the same batter and fry time as cod. A heavy, beer-based batter can overwhelm the delicate flesh. Some savvy fryers use a lighter tempura-style batter or a thinner crisp coating. And the oil needs to be spot-on—too cool, and it soaks; too hot, and the outside burns before the inside is done. That 30-second window is real.
Should You Order It? A Simple Decision Guide
So, you're in a chippy and see "Perch" on the menu. Should you go for it? Ask yourself these questions:
- Are you feeling adventurous? If you always get cod, this is your chance to try something different.
- Do you enjoy stronger fish flavours? If you love mackerel or sardines, you'll likely appreciate perch. If you prefer the mildness of cod, stick with it.
- Is the shop busy and well-regarded? A good, steady trade usually means the oil is fresh and hot, and the cook has rhythm. This increases your chances of getting a perfectly fried perch.
- Can you ask where it's from? If the staff can proudly say "the lake down the road," that's a great sign. If they shrug, maybe pass.
My personal rule? I'll order perch at a quiet, traditional shop in the countryside where I suspect it's a labour of love. I'll avoid it at a rushed city centre spot on a Saturday night.
Your Perch & Chips Questions, Answered
The texture falls apart too easily. Perch has a softer, flakier flesh compared to the firm, meaty flakes of cod or haddock. During the high-heat frying process, this delicate structure can break down, leading to a less satisfying bite and a higher chance of the batter separating from the fish inside the fryer or on your plate.
Focus on inland areas, especially near freshwater lakes and rivers where perch is locally caught. Look for traditional, independent fish and chip shops in towns across the Midlands or Northern England, not high-street chains. Your best bet is to call ahead and ask directly—many shops that offer it do so as a seasonal or occasional special, not a permanent menu item. Some gastropubs with a focus on local sourcing might also feature it.
It can be, but it's not automatically better. UK-sourced freshwater perch from well-managed fisheries is a strong local choice with a lower carbon footprint than imported North Atlantic cod. However, you need to ask about the source. Some "perch" sold commercially comes from large-scale Baltic or Eastern European catches, which have their own sustainability questions. For the most ethical choice, ask if the perch is local and check its status on the Marine Conservation Society's Good Fish Guide alongside your preferred cod option.
Generally, yes, but it's a nuanced difference. Perch has a distinct, slightly sweet yet pronounced freshwater fish flavour. Cod is milder and more neutral, which is why it became the classic—it acts as a perfect canvas for the batter, chips, salt, and vinegar. The stronger taste of perch can cut through the batter more, which some enthusiasts love for its authenticity. If you dislike "fishy" flavours, you'll likely prefer cod or haddock.
The final verdict? Yes, perch is used for fish and chips, but it's a niche player. It represents a different path—one of localism, seasonality, and specific tradition over mass-market consistency. Order it when you see it as a way to taste a piece of regional food culture, not because you expect a "better" version of the classic. It's a different beast altogether. And sometimes, that's exactly what you want.
