A message to our customers

Our fish is mainly caught by day-boat. Unfortunately this means that when the weather conditions are bad our boats are unable to fish. If this is the case there may be a slight delay in receiving your delivery. Please bear with us when this happens as we want you to have the freshest fish.

Thank you for your continued support.

The process

In-season fish and shellfish are caught by local fishermen.

We buy fresh fish direct from the boats every morning, prepared to your specification and delivered straight to you. Hassle free!

We buy the best range from the fish markets in the morning.

We have our own boats landing daily and we cover all of the markets in the south-west!

You order online, we will prepare & deliver to your door.

Your fish will be packed in an insulated box with gel packs ensuring quality and freshness, ready for delivery!

We support sustainable fishing.

We are proud to support our fishing industry and where possible we only supply local seafood recommended as sustainable by Cornwall Good Seafood Guide.

As seen on Sky News!

During the lockdown we adapted our work to bring people all around the country fresh fish, with our boats still fishing to provide fish nationwide. 

Please see Marisco Fish staff in the video below working through the pandemic to ensure fresh fish supply carried on, delivering next day to people's doorstep.

We wanted to be there to support everyone in the hard times and wanted to bring fresh fish at an affordable price. This is the reason many customers who used us through the lockdown have carried on using our services.  


Our Testimonials

First Order was Excellent

My first order arrived and absolutely the freshest fish I have had, from mackerel with the brightest eyes, shows its fresh, to lemon, sole, hake which I chopped up and can eat hake steaks, to some lovely prawns arrived raw and shell on which is the best. Going to make fish soup with the hake head and anything that comes to hand. Haven't had the plaice yet but once defrosted will I'm sure be great. Arrived very cold had been very well packed and arrived in the Midlands from Cornwall the next day. Will I be reordering? Just as soon as I have finished everything. To get the freshest fish without going near a supermarket is the best.

Chris Beynon

So fresh and delicious

Discovered these guys by chance today.. seriously the freshest tuna I have ever had in the UK it was absolutely delicious.. can’t wait for my brill tomorrow. What a find!!!


Fantastic Fresh Fish- excellent service!

It’s the first time I’ve used Marisco. Easy to use website. The fish box was a bit of a lucky dip- extremely pleased with the fish, definitely order again. Really recommend. Looking forward to ordering again soon.

Jackie Dobson

Another great order

Another order just received from Marisco fish and yet again absolutely delighted with the quality and product. If you want fresh fish at great prices, well packed and delivered quickly I can't think of a better supplier than Marisco. We used to use a competitor, but Marisco is now our top choice.

Simon Maasz

Really fresh fish!

We have had three or four orders to date - just about to place another. The fish arrives next day - still very cold in its excellent packing, and it quite different fron supermarket bought fish! Even when we freeze it and cook it much later it still has that really fresh taste. Well done Marisco!!

Stan & Jenny Woods

Fabulous Fish

Today I received my first order and felt obligated to submit a review as I was so delighted with the quality and service. I first saw you on a TV Programme during the first lockdown and was touched by the plight of your industry and how it was affected by the closure of Hotels etc. Although I admit I did have some reservations with regard to how fresh it would remain in transit living in Lincolnshire, that proved to be unfounded it was so well packed and beautifully cold. Again thank you for the prompt service and top quality fish received, something Supermarkets just do not offer ! I will without doubt order in future and recommend Marisco to my friends.


A real treat!

Christmas came to Coventry today on a miserable Thursday! My brother used to ship us a whole hot smoked Salmon from USA at Christmas. Haven't had any for years so it was a real treat to have it for lunch today & certainly came up to muster! Thanks so much!

Margaret & Gerry

Absolutely Fabulous!

Ordered two lobsters, two crabs and some filleted turbot for a celebration. The lobsters and crabs arrived alive, in superb condition and were duly dispatched and eaten the same day (Lobsters were par boiled, halved and then oven roasted with garlic, , butter, ginger, coriander and limes.) We had the turbot the following day pan fried with a beurre blanc sauce, peas broad beans and new potatoes with chives, spring onion and butter. A truly memorable, delicious and sensational experience. Many many thanks to all at Marisco for such excellent quality and service

Maurice Gee

Quality and freshness

We discovered Marisco during March lockdown and have been ordering from them ever since. The fish is so fresh as it comes straight from the day boats and is then prepared and packed with ice to arrive the next day. Have recommended to friends and family and we're happy to know our order supports Cornish fishermen directly. Thanks to Kass and the team.

Lesley Sharp

Beautiful prawns

Please keep the Argentine prawns as a regular on your menu ,they have reminded me of why I loved prawns , after the tiger prawns took over ,and they just became a plate filler . The texture and taste are far superior in my opinion . Since finding your site I have never eaten so much beautiful fish and seafood . Thank you for changing my diet : )

Ps . The fresh mussels are gorgeous too!

Bryn day

Superb fish and service

Quality of fish is unbelievable. Service is amazing, they actually care and respond to emails or even (would you believe it) phone you back which shows they are really amazing. My only warning is you will never eat fish from a supermarket again.


Superb quality and superb service

I have used Marisco a few times and the quality of the fish and seafood is simply amazing. Best fishmonger Online or anywhere! Also, I incorrectly alleged an error in my order, and within 2 minutes I had a phone call politely explaining my erroneous understanding. Such excellent and polite service is rare in the online world. Highly recommended.

Jeremy Blum

Five Star Fish To Your Door From Cornwall

We discovered Marisco at the start of lockdown. It’s by far the freshest, finest fish we’ve ever had. If you have a freezer, you can stock up on all your favourites—cod, monkfish, salmon, bass, and try some new things, too. Ring and speak to Cassius who can help you decide what to order, depending on that day’s catch. Or order online. Delivery is UK wide—so you don't have to be in Cornwall to enjoy Cornwall’s treat.

Alice Kavounas

Great fish

I must have had four or five orders now since I read about deliveries in the Guardian, and every box has contained fish so fresh that I have had to adjust my cooking times. The flavour and freshness have been incredible across a fantastic range, and every delivery has gone like clockwork.

Andrew Mash

Super amazing produce and service

Marisco fish was recommended to me by my friend and I also found the company myself while reading The Guardian.

Being a fish lover, I knew straight away I am in for a treat and I was not disappointed!

A big applause to Cass and his amazing team!


Never going anywhere else again

Excellent quality fish, delivered in perfect condition at a fair price and great customer service. What more can you ask for?

Nick S

Wonderful produce

Great service I discovered during lockdown and like others I will continue to buy from Marisco now. Can’t see myself ever buying fish from a supermarket again. I am only annoyed I didn’t know about it sooner!

Angela Skelly

5 Star Service all-round

We have received 3 orders and all have been excellent. The freshness, the quality and the standard of delivery all 5 star.

Karen Watkins


You will NEVER want to buy fish from a supermarket ever again.

I ordered on Monday 8th June, the fish were caught on Tuesday 9th and they were prepared and sent on the Tuesday evening, they arrived at 8:30 am on Wednesday and we had Milgrim (I had never heard of it either!) for dinner on Wednesday and it was FANTASTIC! easily 11/10,

The fish was perfect, prepared and ice cold and such a lot of veriety, Haddock/Milgrim (from the sole family and delicious) Grey Mullet/Plaice and Monk fish. We have since had the Plaice and the fantastic thing other than the taste is that you don't get that horrid lingering smell of fish for days afterwards, which has stopped me cooking fish, until now.

Thank you again Cass.


Great value!

A good variety of fish fillets, very fresh and great value. Arrived the day after ordering. Would highly recommend

Gary Walpole


What do you get someone for their birthday when they don’t need or want any more things, and you live 2000 + miles away? The freshest, finest, (and usually unobtainable) favorite kind of fish, of course! Thank you for delivering exactly that, and exactly on time to make for a perfect surprise and a perfect treat. I’m told the result was “Sensational!!!!”.

Nikki Jackson

Wow amazing fish!!!

I have just received my second order and am so impressed with the quality and freshness of the fish. The owners of the company are also really helpful. Living near Lincoln I cant access decent fish its a real treat to be able to source such fantastic produce from Cornwall. Will definitely continue using you thank you.

S Lysandrou

Absolutely gorgeous!!!!

Beautiful fresh fish delivered to my door With easy no hassle online ordering .

Thank you Marisco !!! Your produce and service is wonderful please keep up this excellent service.

Jessica Taylor

Excellent Quality All Round

My second Fish Hamper arrived this morning and it certainly did not disappoint. A wonderful selection of fish including hake, monk, mullet and plaice and all very good portion sizes. Fast delivery too, means I will never buy from a supermarket again. Thank you Marisco team!


Fantastic fish

We are half way through our fish order. It has been so brilliant during this lock down period. We’re lucky enough to have our own vegetables so couldn’t be happier to have such great fish to always make a meal. Will definitely continue to buy our fish in future from Marisco.

Rita Preen

So fresh

I received my first order last week and am thrilled with the fish. Even in this hot weather the ice packs were still part frozen and the fish was chilled. The tuna is tasty and the hake fillet is delicious. Smells and tastes straight from the sea. Also cheaper than the supermarket.

Will be ordering again.


Lockdown Lifesaver!

Lockdown meant that we couldn't get any decent fish to eat. The fish box travelled 420 miles to our home in Yorkshire. It was ice cold when it arrived and super fresh. Great variety and exceptional value. It would cost three times as much to buy the same amount of fish from our local market (which would be nowhere near as fresh). We are about to order our second box, and we will continue to buy our fish from Marisco post lockdown. Many Thanks to Cass and his team.

M Lee

Simply stunning

Wow. Very impressed. Prompt delivery with prior notifications, the fish is soooo fresh! Nicely filleted for lazy people like me, and fish by the bucket load. I've been lulled into the supermarket "frozen baggy for Eleventy Billion quid" trap so when my order rocked up it was a real shock as to what you can actually get for your money. Absolutely fantastic. Yup I'm telling all my friends, this is a winner. Winner for supporting our fishing fleet but also a winner for the consumer who gets a premium product at an affordable repeatable price.

Big thanks guys xxx


Fantastic guys

This is my second order from you guy’s, fantastic, ordered Monday arrived Thursday morning .whole Sea bass look amazing plenty of haddock fillets as well .will use you all year round ,great service your a credit to Cornish fishing thank you

Derek Trimmer


Thankyou for delivering our fresh fish all the way to West Yorkshire

The fish is beautiful and even our elderly neighbours who are isolating enjoyed the salmon!

M Sutcliffe

So fresh!

I have placed an order online not knowing what to expect. The person I have contacted prior my order was very helpful and informative. Delivery is not free but fish is reasonably priced. The fish arrived within the few days and was so fresh you could smell the sea! The red mallet and hake were delicious! Definitely will be ordering again. Many thanks!



ordered a £75 box of mixed fish on 26th April, and when it arrived on the 30th we were extremely pleased with the variety of beautiful fresh fish and the quantity. some amazing mackerel and the biggest skate wings we have ever seen. looking forward to the next box

Craig Davies

Excellent Service and Excellent Fish

The quality of fish and the personal service you get from these guys is the best in the Cornish region - Nothing is ever too much trouble and the quality of fish is unbelievable!

Barry Neal

Absolute Wonderful Fresh Salmon Fillets

Wonderful service inspired by seeing the company on the News discussing their fresh fish produce. Highly recommended.

J Collins

Superb Fish!

I watched a section on the BBC about how fishermen were being affected in the current crisis and I noted the name of the company. I placed an order for a hamper, not sure of what to expect. I received the order yesterday and was thrilled with the quality of the fish. My husband filleted the Mackerel himself last night....I have never seen such a beautiful fresh fish. I had the John Dory..absolutely delicious. I came home from work expecting the house to smell of fish....nothing. So, so fresh. I will be ordering more. Thank you.

Debbie Gaynor

Excellent fish and shellfish

My order came today had to wait a week, but do understand the wait because of what is happening at the moment. I’ve had a variety of fish and shellfish from haddock ,seabass,Scollops and crab. The quality is excellent, and the quantity of the fish is also fantastic . I will have no problem recommending Mariscofish thanks very much guys.

Derek Trimmer

Fabulous Fresh Fish!

Although our delivery took a while due to the current crisis, it was well worth the wait. The delivery eventually came overnight and arrived this morning. The fish is absolutely fresh together with the crevettes, frozen king prawns and scollops arrived in polystyrene packaging packed on ice. We will without doubt order from these guys in Cornwall again soon.

Steve Jelley

Great service great fish

Thank you for the delivery, ordered Thursday and was here to me in Kent Friday morning.
Great selection of fish lovely thick cod, hake, monkfish and Salmon.

Would highly recommend if you want fresh, delicious fish. Will be ordering again soon.

Joe Maxwell

Superb Fish

I took delivery of our first order of fresh hake from Marisco yesterday just in time for Friday night fish and chips! It was easily the best fish we have ever tasted. I will be placing further orders in the future and shall look forward to trying other products in their range.

Prof. John Lewis

Brilliant seafood company from sea to door!

This is my first order, having watched a report on Sky News about how the fishermen are struggling in this crisis, and I noticed the name Marisco on the polo of one of the interviewees. I google them and voila. I didn't expect much because I am not sure how fresh it can be if the delivery can take a day!

Thank you Marisco!!!


Highly recommend

Wonderful, really fresh, top quality, good selection. Couldn't be more impressed.

Value for money.


Excellent, thank you!

Excellent. Lovely Fresh smell. Glistening eyes. Large scallops with coral.

Thank you

Fiona & Peter

Freshness and taste couldn't be better and at very reasonable prices, comes in great packaging that keeps the fish cold.

Would recommend anyone to use Marsico's as long as there is always enough for us!!!!

phil bamford

Delicious fish and shellfish

Found Marisco via seafoodcornwall.org.uk. Great service and amazing fish. Ordering again this week for myself and a few neighbours.

Rupert Baker

A silver lining!

Seeking fresh fish during lockdown, we were lucky enough to find Marisco. We cannot recommend them highly enough! The fish was of superb quality - straight from Newlyn that morning - expertly prepared as we'd asked, and great value. The customer service, packing and prompt delivery were excellent. We shall carrying on ordering from now on. Thank you Marisco.

Michelle Brown

Fantastic Fish!

Our first delivery on Wednesday was a £30 selection of fresh fish and locally smoked salmon. Brilliant value and quality, and enough to share with family and friends. Help to keep our fishermen fishing!



The fish arrived within 24 hours professionally packed... I have never had or seen such fresh fish ! And such value for money...


Quality service and fresh fish

Cass and his team gave me top service when I contacted them about their selection. Fresh fish superbly cut. I couldn't ask for anything more.

Richard C
