Fish Fry Effects on Stocking Levels?
Hope someone can help on this...
I have a 160 gal. outdoor pond that is doing incredibly well. So much so that everything conceivable is shagging in it (snails, frogs, goldfish, algae eaters, etc.). I have already had a tadpole explosion (manually removed 1000s - only a hundred or so left, I think) and several rounds of hatched goldfish fry that have impacted the pond significantly.
Here is the question/problem at hand:I have about 25-inches of adult goldfish presently in the water and 8-12 fry in the half-inch to 1-inch range (that have survived the tadpole invasion). At what point do I need to be concerned about the stocking levels becoming a problem as the fry grow, as I do not want to lose any of my adult fish?
Thank you in advance for any advise.
OK - since no one answered...here is what I did...
Realized I had a minimum of two dozen fry (some nearly 1.5 inches). Dug out a hole and placed a 35-gal container I was saving for a water garden and turned it into a nursery. There are probably another dozen or so in the large pond, but it will take time to get them out. The new pond also gives me a place to put all of the extra anacharis that is growing.
If any one can give me any advice on maintaining a goldfish nursery, please don't hold back.
Thanks and Peace,
I think the fry aren't going to affect the pond much, since they're quite small and obviously give off less waste than the full grown ones. If you have a good filter system, then there's nothing to worry about. However, the best way to know is to check your water parameters.
In my opinion, the fry become a concern once they become big enough to be sold. In other words, they're as big as the small goldfish seen at the pet shop.
You will not have a problem as natural selection will occur. But if you want to try and save and grow them all then you may have to get creative.
are you going to sell some to the LFS ?
natural selection and a good filter,should make it ok,
would there be any possibility of making a larger pond ?
