Loosing my fish to predators!!!!

[bob]

For the last year we have lost several fish to a predator. I blamed a cat or a racoon but could never catch anything in the act. We now are pretty sure what the predator is, a heron. This past week we twice caught a heron standing beside the pond and then wading. At this point all of our larger fish are gone. I'm sure others have this problem, what do you do? If nothing else I may stretch some monofiliment fish line across the pond a few times in a criscross fashion.

Any suggestions? We hate loosing our fish.

1. Depth of pool. If the pool is atleast 3 feet deep at the edges then the heroning shouldn't be able to get to the fish at the bottom of the pool. Their legs don't bend.

2. Decoy fish that float towards the top, plastic. The bird will trying eating it and find that he can't a may give up on the real fish.

3. Motion activated sprinklers might help.

The only problem with the net is that when you remove it the bird will probably return.

Just some ideas. Hope they help.

Thanks. May try the plastic fish. We do have a fountain but it tended to clog with some algea so I took the fountain part off and use it as a bubbler. The pond is not deep and to dig deeper would require a complete redo.

Someone had mentioned that heron are not a social animal and that placing a plastic heron would keep the live ones away.

Are heron a proteced species?

You mught get lucky by placing another bird there, it could make the other bird think that there is already another bird there and it would move on. I have no idea if they are a protected species.

Are heron a proteced species?

Yes, they are
I read an article were a breeder in calif. had a problem with them. They tried the heron decoy, and the bird was seen circleing above but not landind for two weeks, getting closer to the ground every day. He eventually started eating fish again. So the breeder said at of lack of anything else to try he thought he would threaten the bird. so he knocked the decoy over. The bird did not come back.
Just thought it was funny.
Good luck

That's too cute!! I have heard of them trying to mate with a decoy so if you use one be sure to move it around alot. Good Luck, Gail

I have had a decoy great blue heron in my pond for 10 years and (knock on wood) I have lost no fish to herons. I have only seen 1 heron lite by the pond and it was a baby, all fuzzy headed, and I scared him away and he hasn't been back. I recently added a floating plastic alligator cuz I liked him and maybe he is a deterent also. I am also surrounded by canals and there are herons everywhere! Yes, they are protected in Florida. So, it worked for me, it may be worth a try! Good luck.

good. there is at least some truth to it then.

We used to have a pond on a flyway between a heron rookery and the river that the used to feed. Talk about a setup. We were fortunate that our dogs liked to chase Herons so there was no need to use other measures.

Got my decoys out waiting for trouble

Just as an aside we also used to get the occasional wood duck diving in for a swim. It was a blast watching these guys first circle then dive in at high speed, drop the "flaps' and land like an F-16! Not sure if they might have helped keep the Herons at bay.
