Since my goldfish spawned in my aquaponics system I have been reading up on the species. Just thought I would share some basic knowledge for those considering working with this species. Goldfish were originally kept as an aquaculture food source! Yep. Starting around 200 A.D. in china as food. These fish are believed to be descendants of Prussian Carp. Goldfish are omnivores and will eat pretty much anything that will fit into their mouths. The non-facy varieties can liver for more than 40 years. The fancy types only 5 to 10 years. They can handle ph from down around 6.0 up to above 7.5. They can handle extremely warm water... or live under ice. They get to around 14" long and several pounds. Breeding after 2 years of age... up to several times a year. Perhaps these are a great fish for your particular needs or can just be a small part of your systems balance! These little scavengers will assist keeping algae at bay and pretty much everything else as well. https://youtu.be/fKlPaFCaGFs https://youtu.be/Ahnr94mX_vM https://youtu.be/W2Xd2tAFJgM |

Keep in mind back then they were fish that had just been pulled from the wild. Fish that were tough, not too big, and would eat just about anything. These days they are worth a lot more as an ornamental... And... an emergency food source! lol I suppose if I and my children were starving... my goldfish would begin to look pretty good.  They do grow slow for a food fish though. So catching/using their wild relative the Prussian carp may not work... or... would it??? Perhaps someone will try it some day. https://retrieverman.net/tag/prussian-carp/ |
