How many fish is too many fish?

One formula for determining how many fish you can have in your pond is: 1 inch of fish for every square foot of water surface. That gives you some different options. You can have a lot of little fish or a few big fish. For example, a 6ft by 8ft pond has 48 square feet of water surface. You could have 24 2 inch fish in that pond according to the formula. You could also have 8 6 inch fish or 4 12 inch fish. We all no thereis one problem with this formula and maxing it out oo early. Fish Grow. You should allow for the growth of your fish when deciding how many to put in your pond. Keep in mind there are many other factors that have to be considered when following this formula. Your pond needs sufficient filtration and/or aquatic plants to handle the number of fish. You don't want to overfeed them since that will produce more fish waste and could cause water quality problems. If you put in too many fish and they outgrow the size of your pond, what will you do with them. These all bring up topics that pond hobbyists deal with everyday. Please post questions, comments and solutions that may help a fellow pond owner.

It seems like that rule has overlooked a significant factor though ... Ponds (and filter/pump performance) are measured by volume (gallons) rather than surface area.

But I suppose it's ok just as quick rule-of-thumb, particularly for a beginner who's still learning about filtration & plants.

You're leaving out one very important variable (that we found out the hard way this past summer) -- fish tend to multiply! We had 12 fish in May, now we have about 32 (they're hard to count because they move around so much!) I'm a little worried about next summer!!
