Marrfish is unlike any other wholesale fish and seafood supplier as we own our own fleet of fishing vessels, and therefore have unrivaled access to the best fish from our boats.

Marrfish have been brilliant since I introduced them as a supplier. They have competitive pricing, excellent customer service and most importantly deliver great quality fish

-D and D, London

Marrfish is my go to fish supplier. Always fresh, beautifully packaged and delivers early. They have great daily specials as well. I wouldn’t use anyone else.

-Island Grill, London

It has always been a pleasure to work with Marrfish over the years. Their products are always fresh, consistent and great quality. The pricing is competitive but more importantly they go the extra mile for us in terms of customer service. Long may it continue and I would certainly recommend them.

-Café Murano, London

We have been working with Marrfish for many years now and we cannot fault this company. Their attention to detail, top class produce and reliability sets them apart from other fish merchants. They always go the extra mile for their customers. The fact that Marrfish vessels adheres to MSC guidelines is also very important to us.
On top of that they are lovely people to work with!

-Maison Bleue, Bury St Edmunds

I still remember the first fish that Marrfish sent me. A whole large cod. I could not believe that they could get me fish that fresh. It looked as though it should still be flapping about in its crate. 8 years on I am still using them and that quality had never dropped. On top of this they are great people to deal with and I can’t recommend them highly enough.

-1921 Angel Hill, Bury St Edmunds

Our restaurants work with Marfish already 4 years. We were always looking for fresh and quality produce and Marfish was always providing it to us. The big plus is the daily specials with bargain prices and opportunity to negotiate about the prices for any products.

ALL of our boats and skippers are committed to sustainability - we want there to be fish for everyone for years to come! We carefully monitor our quotas and work hard to maintain fish stocks and to discourage over fishing. If we work smarter there will be fish for our children and our children's children. We're a wholesale fish supplier with a difference - we care about the ocean!

All of our boats are involved in the Fishing For Litter Scheme. We carefully collect litter from the ocean and return it to land for recycling or proper disposal. This ensures we're doing as much as possible to rid the ocean of plastics which threaten every aspect of marine life. What other wholesale seafood supplier can say that?

The weather affects everything we do. It affects the duration of our fishing trips. It can also heavily impact the price of fish. During bad weather fishing boats don't go out to sea - this determines the amount of fish available at the markets each day. A shortfall in supply could push up the price.
