question about inbreeding.

[DLV082]

To set the picture I have a 900gal pond give or take a couple of gallons heavily planted. It is about 4 years old and going well. When I originally stocked the pond with shubunkins, I put 20 in the pond from 4 different sources. Well, as you can guess their are quite a few more in the pond at present. (no I have not tried to count them)

My question is how many generations before I start to get worried about inbreeding? I have already taken some of the offspring with undesirable traits (there was nothing wrong with them just not what I am looking for in a shubunkin) from the pond and given them to my LFS. Should I be seeking new blood for my pond already? If not when?

I didn't intend on breeding them to start, but nature has taken its course and I now have some very nice fish and the bug has taken hold.

Cheers
Debbie

Surely someone knows the answer to the above.

Try asking on goldfishkeepers.com. There are quite a few people on that board with lots of practical experience breeding goldfish long term. They would probably be better equipped to handle your queries.

Thanks for the info. Will give them a shot, hopefully they have the information I need.
