Mark Davies
  • The history of Cuttlebrook Koi Farm and how he and Lisa built it
  • Breeding koi
  • Koi diseases
  • Koi genealogy
  • Filtration
November to March

Mark attended Sparsholt College from 1983 to 1985 where he studied fish farming, water chemistry, geology, fish farm construction techniques, fish health and disease diagnosis. During his time at Sparsholt, he worked on several fish farms in the UK and also on carp farms in France and Hungary. When Mark set up Cuttlebrook Koi Farm it had ponds but no electricity, mains water or sewage facilities. By dogged persistence and support from his wife, Lisa, he has turned it into the successful koi farm that it is today.

Nicholas Stinton (CEFAS)
  • Cefas and the control of serious notifiable diseases
  • KHV (the facts!)
  • Aquatic Animal Diseases
Weekday evenings only (plenty of notice is required)

The Fish Health Inspectorate (FHI) is the official service for the control of serious diseases in aquatic animals in England and Wales. We act on behalf of Defra and the Welsh Government and are based at the Centre for Environment, Fisheries and Aquaculture Science (Cefas). We are responsible for preventing the introduction and spread of serious diseases in fish, shellfish and crustacea. We aim to send the inspector responsible for the area the club is in so they have the most relevant person delivering talks. We don’t charge and just try to arrange evening talks alongside an inspector’s regular work in the area. It is difficult to give these talks at weekends as we have limited resources. Please make bookings early to allow us time to schedule them along with our normal work in that area.

Syd Mitchell
  • Pond construction and filtration equipment design
  • How the choice of equipment affects water quality
  • Water quality and testing
  • Koi physiology, health, diseases and treatments
  • Water samples also taken away after talks, analysed and a full report and advice sent back
All day seminars or weekend and evening club presentations

Over thirty years of designing and installing filtration and water quality control equipment for the leisure industry followed by studying koi physiology and health since 2006 has given Syd a lot to talk about. He has both OATA Advanced Diplomas. Hanna Instruments asked him to specify the koi kit for their new electronic tester and write the koi keeping booklet that accompanies it. He has written over 100 magazine articles and, consequently, was recruited by the online teaching organisation Koi Organisation International to teach courses in Water Quality and Advanced Filtration and to write new courses plus technical papers and books for their website store.
