Texmaster,
I have to state that I am of the same mindset as Callingcolleen. I am not so sure that I agree with the Japanese method that she cites, I think that is just more of the same invasion into the aesthetics. But, I certainly would not wish to cover my pond with ugly wire or fencing. It seems to defeat the complete and total purpose of having a pond in the first place. Wires and fencing and zigzagging cables or twine? Really? Why not put the plants and the fish in huge aquarium inside the house? At least it would look nice there without the netting and fencing and what not. And the plants and fish would be safe. Ok, I agree, I digress too much.
Hope you understand what I am trying to say here. I just think it is a shame to have such beautiful garden ponds or fish ponds and then cover them up with something tacky and ugly. My Mom's neighbor erected a nice trellace over the top of his mini pond for his vines to crawl over and grow on. Just the trellace alone would keep out any feathered criminals and it looks really NICE! He constructed it out of 2x8's and 2x10's and 4x4 posts. He painted it forest green and doggone if it doesn't look relaxing and shady and comfortable!
I like the "wild" nature better than the attempted domesticated nature. In other words, unless I was raising Koi for money or show, I would have a big pond full of goldfish and be thrilled that the herons and cranes came to dine right out my living room window. That is real nature and you won't get that aspect just watching fat fish swim aound in a big pool and eat Purina fish chow.
I apologize if any of this sounds crass, it's not intended to be. I am merely attempting to inspire you to contemplate some other means to protect your pond in a more aesthetic way and at the same time, realize that nature is cruel because it is simply the way of the natural world and, if you can find some way to bare with it, it is quite a learning experience as well as exciting. It's the BEST REALITY SHOW ever!
