I have a fish pond in my back yard. With four (used to be five) big fish. There is a pelican that lives around my house that has killed one fish that I know of. How with out killing the bird can I protect my fish? I have a net over it but this is not visually pleasing, are there methods or devices made for this problem?
There are several ways to keep predator birds away from your fish. One is a motion activated device called a 'scarecrow.' It shoots a stream of water at any intruder...you included if you don't forget to turn it off.
"Gator Guard" is a floating alligator head that works very well.
Some folks cover their ponds with netting, but I think that looks ugly.
Be sure there are plenty of places for your fish to hide. Under flat rocks that are on top of cinder blocks. Put in plenty of submerged vegetation. If you feed your fish, they come to the surface when you walk up. They can't tell the difference between you and an intruder, so they come up when the bird appears. Think about not feeding your fish, unless you have koi.
