I shall ignore Eric Edwards comments as they come across as being so damned rude and insulting. Seems he has some attitude.
Chris - Yes we did get a section 30 to remove them. The pond we put them in was at that time quite safe and well sectioned off until the massive floods in 2003 when the Thames was suddenly one mile wide. Even Noah couldn't have envisaged that.
My comparison with pike and cormorants is that they both eat fish, but small pike in particular eat small fish. And when there are a lot of them, they are unlikely to start eating each other and therefore regulate themselves.
What we had as a problem was that the pike never got any bigger than 6 lbs. They would eat other pike upt to 2 lbs, but they also restricted the other fish, other than tench, from growing to anything over 4-6 ozs.
In a situation where all stock of fish are depleted including pike, the small pike will multiply first and become the greater predator. It will take maybe 8 - 10 years before any get to a size where they will live more happily off killing other jack pike. In which time, we were spending thousands of pounds feeding them with fish introductions to balance out the water.
Now unless you have a degree in marine biology or you know the particular water I speak of very well, I suggest you keep your counsel. We examined the situation very carefully and took the best advice from everyone concerned. The fish were placed into a pond, only yards away, that we were not allowed to fish and could well have thrived
I just have one question for eveyone - why is it that in angling circles, anyone that disagrees with you is a complete idiot, moron, or cretin? You same people are always the first to bleet about having the freedom of speech and the right to express an opinion. Ah, so long as it doesn't conflict with yours.....
