Abstract: | The method of collation of angling results at Ffestiniog fishery is described. Rod averages calculated from returns are always higher than those assessed by the fishery bailiff. Two studies indicated that, although there is no reason to question the veracity of returns, those received represent a sample of anglers which is biased towards the more successful. The care needed in extrapolation from angling returns is emphasized and it is demonstrated that only the bailiff's estimates of fishing success lead to sensible estimates of the seasonal catch. |
