Along with the stated reasons not to use nets I
have a real concern with my two labradors. I think
netting my pond would be a real danger. They like to drink
out of the pond and the worry would be if one fell in or was
pushed in while playing. No fish is worth the lives of my
dogs. I also have concerns with birds and squirrels getting
caught in the nets.
Nets just don't work for all ponders. We have to offer other
alternatives. I don't have a problem with herons and kingfishers,
they visit from time to time, but I use the heron scarer, I have
fishy condos, tree cover, plant cover and dog patrols. None
of my birdy visitors have cleaned out the pond. I put my bird
losses at about 4 fish max over ten years.
Anyway that's the nice thing about newsgroups, we can offer
all sorts of different options for flummoxed ponders.
