What should you check before buying?
Start with product-level sourcing evidence, then check whether the fish and its preparation will work for your Easter lunch.
| Priority | What to check | Your needs |
| Sourcing evidence |
For wild-caught fish, look for an MSC label on the product. For farmed fish, check for ASC or other credible farmed-seafood assurance. A retailer policy is not the same as certification of the pack. |
I want sourcing evidence for the fish I’m serving, not just a general statement about the shop. |
| Fish and origin |
Read the fish designation and available catch or farming details. The Marine Conservation Society advises that neither wild-caught nor farmed fish is automatically the better choice; the particular source and production method matter. |
Before choosing between cod, salmon or another option, I want to know which fish the pack contains and where it comes from. |
| Meal format |
Compare fillets, larger portions and coated products by pack weight, portion count and cooking directions. Check whether the instructions fit your oven or air-fryer plans. |
Will there be enough for everyone, and does the format suit a plated main course or a more casual lunch? |
| Ingredients and handling |
Read the current allergen declaration and any bone warning. Follow the pack’s frozen-storage, defrosting and cooking instructions. |
I’m cooking for guests with different requirements, so I need to check the exact product before planning their portions. |
Brand and retailer references
These sourcing statements provide context for comparing packs; they do not establish the certification or ingredients of every product a brand or retailer sells.
Birds Eye
Birds Eye offers frozen fish formats including fish fingers and coated fillets.
- Birds Eye states that all the wild fish it sources in the UK is MSC certified.
- Check the chosen pack’s label, ingredients and allergens; the brand statement does not describe every detail of an individual product.
Young's
Young's has frozen seafood in plain, coated and meal-oriented formats.
- Young's describes responsible-sourcing principles that include traceability and environmental stewardship.
- Its policy does not replace a check of the selected product’s sourcing information and allergen declaration.
Tesco
Tesco sells own-brand and branded frozen fish and seafood.
- Tesco PLC reported that 85% of its UK wild-caught seafood was MSC certified at the beginning of 2026.
- That retailer-wide figure does not establish MSC certification for a particular frozen fish pack.
Sainsbury's
Sainsbury's sells seafood across fresh, frozen and tinned ranges.
- Sainsbury's says many of its seafood products carry MSC or ASC assurance labels.
- Its sourcing policy also refers to improvement pathways, so check which assurance, if any, applies to the item you choose.
Asda
Asda lists frozen white fish, coated fish and other seafood formats.
- Asda stated that, in 2024, 94% of wild-caught fish sourced for sale in its stores was MSC certified or working towards MSC certification.
- Working towards certification is not the same as an MSC label on the product; inspect the individual pack if certification is your priority.
M&S
M&S presents frozen fillets among its fish options for meals.
- M&S describes the frozen fish on its category page as responsibly sourced and traceable.
- Check the individual product for its fish designation, sourcing details and any certification label.

Frequently asked questions
What does the MSC label tell me about frozen fish?
The Marine Stewardship Council says its blue label identifies wild-caught seafood from a fishery independently assessed against its environmental sustainability requirements. It applies to the labelled product’s wild-fish supply chain, not to every item from the same brand or retailer.
Is wild-caught fish necessarily a more sustainable choice than farmed fish?
No. The Marine Conservation Society advises that neither production method is automatically better. Check the particular fish and source: MSC is relevant to wild catch, while ASC or another credible farmed-seafood assurance is a more relevant starting point for farmed fish.
Can I use a supermarket’s seafood policy instead of checking the pack?
Use the policy as context, but check the individual pack if certification matters to you. Retailer sourcing statements may encompass both certified products and improvement pathways, which are not the same product-level claim.
What should I check before serving coated fish to guests with allergies?
Read the exact product’s current allergen declaration. For example, Joybuy’s listed Birds Eye battered fish fingers contain fish, wheat/gluten, milk and mustard, while its listed Young's scampi contains crustaceans, oats and wheat and may contain fish or molluscs. Do not apply either list to a different product.
How should I plan frozen fish around Easter lunch cooking?
Use the chosen pack’s portion count and cooking directions to plan oven space and serving time. Follow its storage and defrosting instructions too: the Joybuy-listed frozen fish examples specify storage at −18°C or below and say not to refreeze after defrosting.
