Can native frogs and fish coexist in a small backyard pond? have a backyard pond that’s pretty small- about 5×10. I used to be told that getting fish would help keep the pond clean of algae, which might be helpful. But I’d like to have frogs and an area garden centre has native tree frog tadpoles available. Is there a sort of fish that might not eat the frogs? I realize that fish would likely eat tadpoles, but I’m hoping there is a fish species that wouldn’t choose the adult frogs. The classic backyard pond fish maybe a goldfish, but they get large enough they’ll surely eat up the frogs.
There are a couple of considerations when deciding what to try to to with a water feature on your property.
The size of your pond isn’t that big, so it’ll have limited potential to support a diversity of wildlife species. Since your pond is little, it’s very likely that each one the tadpoles are going to be eaten if you add fish due to limited space.
Another consideration is how the pond is meant. Wildlife answer structure, or how space is arranged. The more vegetation, like shrubs, grasses, and other plants, also as logs, branches and other items that make places to cover, the more chances the frogs need to escape the fish. The underwater structure also provides fish places to cover. If tadpoles become adult frogs, they’ll or might not stick around if the pond doesn’t have the proper sorts of vegetative structure. There are only numerous places to cover and find food during a small pond, though, albeit you’ve got this type of structure.
Any wildlife species goes to wish to be ready to find the proper food to grow, develop and reproduce. If the tadpoles do not have adequate algae and other food to eat, they will not become adults. If they are doing become adults, but the pond isn’t attracting enough insects, the frogs won’t survive or will advance to look for food. And, of course, the fish might well use the tadpoles and adult frogs for food.
Another consideration to believe with a pond is oxygen supply. Because a pond may be a closed system, it doesn’t have an opportunity to exchange its water on a daily basis – that’s unless yours has a recirculating or water supply from your house or another water source. Water movement, either from water or an aerator (bubbler), improves the probabilities that the tadpoles and fish survive. Continual water also improves temperature regulation, preventing the water from getting too warm. Fish and tadpoles have a variety of temperature that they have for survival. Water movement and oxygen also will help prevent your pond from developing excessive algae growth which will eliminate open water and consume all the available oxygen supply as algae decompose. Avoid over-fertilizing the encompassing area, as runoff from lawns adds nutrients to water features and causes excessive algae growth.
I’m not a fish expert and would recommend doing a touch more research on appropriate fish species for little ponds. Always follow regulations from the Oregon Department of Fish and Wildlife when choosing to release fish during a pond.
The last consideration of any pond is what else could be interested in the pond. There are many samples of backyard ponds attracting the eye of Great Blue Herons and other predatory birds. Herons will clean out a pond of fish and frogs very quickly and are known to cost owners tons of cash when investing in expensive fish like koi. it’s also possible that a pond will attract frogs without stocking them with tadpoles.
Finally, I might ask some more questions and do more research about what sort of frogs the garden centre is selling and if they’re truly a native species. there’s a risk of releasing exotic species into the environment which will become a significant invasive, outcompeting native frog species that already sleep in your area (see Oregon Department of Fish and Wildlife’s aquatic invasive species website. for instance, bullfrogs are a significant invasive species in Oregon, and can consume fish, native frogs, young turtles, and even birds! Native frogs have tons going against them and in many areas, with populations declining significantly. Also, there’s a high risk of releasing pathogens into the water, like fungi, bacteria, and viruses, that are carried in on outside sources, including garden centre tadpoles. they will then spread to native frog species within the area. While it’s great that you simply want to use native species in your pond, I like to recommend doing more research so you avoid these potential issues. Again, ask the Oregon Department of Fish and Wildlife to form sure you are not choosing prohibited species (see list of prohibited species)
Having both frogs and fish successfully within the same pond is perhaps unlikely. I might suggest picking one or the opposite, perhaps the fish, then give the pond a while to ascertain if it also attracts frogs from the encompassing area.
