About The Farm

At Cuttlebrook Koi Farm we breed beautiful Koi – Nishikigoi to be exact.  We have been breeding and growing Koi at our farm since we first built it in 1990 and over the years have developed a reputation for producing the finest quality Nishikigoi.  We know of no other purpose built, commercially successful, Koi farm in the UK today. We began trading as Cuttlebrook Koi Farm in 2001 and over the years, Koi bred by us have won hundreds of awards at Koi shows around the country, competing against Japanese imported Koi.

We are always here but we are pretty busy most of the time so, if you want to visit us, just get in touch and let us know when you would like to come and we will do our best to make sure someone is free to help you – we are happy to answer any questions you may have or help you to choose Koi for your pond or business.  Alternatively, we are open on Saturdays from April to November without an appointment between 10.00 am and 4.00 pm if you just want to drop in for a look at what we have for sale or simply to buy some Koi.

In 2017 we added a new division to our company, Marisa Koi Farm, through which you can buy, online, not only the Koi that we produce but also Japanese imported Koi to compliment the range that we produce here on the farm. On the Marisa website, we also have a range of dry goods, including our own brand of Koi food (the same food that we feed our fish on here at Cuttlebrook), and our aim is to sell only products that we would use ourselves, or those that we would recommend.

Mark now travels to Japan twice a year to buy Koi to sell through Marisa Koi Farm and is happy to take customers along with him. If you want to join Mark on his next trip so that you can experience Niigata, the home of Nishikigoi, to visit the breeders and choose your fish direct from those breeders, let us know.  All the information is on our Marisa website on our Koi Trips page.

This is our story from the beginning:

My name is Lisa Davis, I am Director, administrator, secretary, farm hand and mother to our two sons.  My husband (Mark Davis) and I  run Cuttlebrook Koi Farm right here in Oxfordshire, UK.

When I met Mark in 1988 I didn’t know anything about koi but at the time he was writing three of the chapters for the Interpet Encyclopedia of Koi (history, breeding and feeding), a good way to impress a girl!


I found out that Mark had been to Sparsholt College from 1983 to 1985 and studied fish farming – of course in those days you had to work for a year on a fish farm before they would even let you on the course.  He has some great stories about his year spent living in a soggy caravan at the side of a loch in Scotland!  At Sparsholt he studied water chemistry, geology, fish farm construction techniques, fish health and disease diagnosis amongst other things .

During his time at Sparsholt he worked on several fish farms in the UK and also on carp farms in France and Hungary.  He had some amazing experiences during that time. It was here that he encountered his first koi amongst a lake full of table carp in France and it was then that he decided that he wanted to learn more about them.

Mark has always been a very creative person. A Koi breeder creates living works of art so breeding Koi combined his two passions , art and fish!
