Ornamental Fish Production and Management (1+1)

12.1.1 Pond fish keeping

The majority of garden ponds contain a range of coldwater fish species notably goldfish, carp, koi carp and tench, and are often relatively well-planted. Accessories and equipment are usually kept to a minimum and the establishment of local wildlife (e.g. aquatic insects and amphibians) in the pond may be encouraged. However, the establishment of ponds especially for the maintenance of koi carp, usually with a minimum of submerged vegetation and sometimes with quite elaborate filtration systems, is increasing.
