After searching for this graph on the web without success, I've had a blast at drawing it myself from all the studies I've collected from various waters over the years.
Without hindsight I only kept the bits that were to do with growth rates, so without spending hours re-tracking them down I can't credit the sources - probably should track them down. And I've only really been interested in waters that are similar to the River Wye, discounting trout waters, small streams etc.
If anyone has a link to a similar graph done by proper science bods please leave me a link in the comments - thanks.
Here are some stats from the other side of the pond:

Some interesting facts and figures in Falkus and Buller's Freshwater Fishing, Cresset Press, 1975 (The Pike - Age and Fecundity - pp 134-144), including a "50 1/2 lb female pike netted from Lough Mask in 1966 age 8 years +".
ReplyDeleteI read somewhere that the Chew Valley forties are 8 years old, and they don't live past nine years - not sure if it's true.
