Hi there hope you can
help answer this question lots of frogs are in my pond and they are hatching lots
of babies !Is this safe for my KOI fishes?is there anything we need to do to stop
them many thanks
You got frogs?
If you are situated, as we are, in the
upper Midwest, it's too early for frogs. If your tadpoles are tiny( about 1/2
inch long) and black, what you got are American toads. Be very happy. Toads are
non-toxic and while courting, sound like crickets on steroids, emitting a long,
drawn-out chirr. Their eggs are laid in long, gelatinous strands. They will mature
into useful and handsome garden companions who will hide in your underbrush and
eat all your garden slugs. They don't taste very good, and your fish will leave
them pretty much alone. They are not disease carriers.
on, as the weather warms up, you may get frogs. The egg mass is a large clump,
the tads are about i.5 to 2 inches long, and koi find them delicious. Green frogs
are native here and are recognizable by skin folds extending from their tympanum
down along their flanks to their bottom. They are beneficial insect-eaters. Their
song is a "glump" or "boing".
sound like a disappointed donkey or a low-pitched bass fiddle. They get big, and
in their niche are an apex predator, able to catch and eat baby birds, small rodents
and all your goldfish. Their tads are large and heavily speckled. They are a brighter
green than green frogs and have a blunter nose and a smooth back. If you've got
these, they need to be introduced to Mr. Raccoon or otherwise escorted away from
your pond. One of our naturalist friends once remarked that the only reason that
bullfrogs do not rule the world is because raccoons find them tasty. Big koi will
slurp the tadpoles up like gumdrops.
It's the Great Circle
of Life, writ small.
BTW, if what you have are
indeed greens, and you are local to the Chicago area, please let us know. Our
resident population is pretty scarced-out and we'd love an egg mass or a buncha
