. Now it's starting to make sense as to why my koi are not growing as fast as they should.
Will definitely continue to practice my water-changing religion and hopefully the results will start to show![/quote]
Growth is mostly determined by genetics .The feeding pond size water changes etc play a very small part providing you have a koi pond in the first place . Based on same care large parents produce a larger amount of large young . Bently is 98cm so no surprise that some of the larger young are now over 15in and will grow to 34in . Even from large parents very few large fish are produced . In some cases none .
The cost factor has to be taken into consderation in trying to produce large fish , mostly it is a smaller market and the costs of heating feeding and space involved few breeders can afford to compete .
