Rule 1 you live in the UK you need a absolute MINIMUM of 4 ft deep water to house cyprinids outside in winter, The bigger the pond the bigger the fish, simples, cyprinids grow to the size of their environment.

Rule 2 dont feed em Trout pellets as it will kill em off early

Rule 3 10% weekly water changes are not optional

Rule 4 If you have small kids that are not olympic standard swimmers dont build a pond

In the UK in the middle ages up to the start of the industrial revolution almost every village and monestry kept a STEW POND, stew ponds were growing carp and tench in for food. Carp is still a staple fish in most of the Balkans, Steppes, and Northern Europe.

In Poland, carp is the centrepiece of the Christmas celebration meal (served in the evening on Christmas eve).
