minime

I was recently walking along the hogmill in ewell around beggars hill. There are a couple of bits there where its more like pond and i saw 3 or 4 good sized fish at least 5or 6lb. not sure of the species but anyway. there is kind of a park a bit further down and the are some quite nice healthy sections of river. So my question is, now i know there are some fish about, are you aloud to fish here?? cheers
