Frank :

Wow what neat charts !!!

Mine are made up of simple notes of lengths and weights -- then a rolling average for all fish for the year. \:o I use a hand held lip grip digital scale.

I may be wrong but here is what I see and it looks very good. \:\)

On chart one notice the groupings by color. Yellow a bunch at 10-14 with a couple fast growers at 15. Then look at blue grouping -- the group has moved up (though fewer as expected) to 13-15 with still a couple fast growers at 17-18. Now to 06 early results - the points at 16 I bet are the first ones in the main group which has now moved to 16-18 , the one at 10 is a next generation fish (18mth offspring) and the one at 12 is also in that group and is the top of a group that ranges from 10 -12. A good question is how big and long are the fast growers (blue points 17-18) out of the first group now -- I bet in the 21in. range.

Second chart. The range of statistical differences are narrowing. Each year less highs and lows from the norm. But note 2 things. One the entire range of blue dots have moved over 100% RW while the band narrows. Two no red dots under RW. Again it appears the entire curve is narrowing and moving higher above RW norms. One thing to watch is for the right size food for the bigger fish. I note that one of the two blue dot fast growers is 20% under weight and no info for this year. Do you have enough 4-7in. BG or other large forage for them.

This is a great example of the need to age fish that Dave Willis needs to review. Not that you have a problem but to get the entire info base you need to do seine surveys (fishing misses data at the low/young end) . Also RW don't give the entire story on age and age classes but are still very good. Look for more on the subject in an upcoming PB issue.

It looks like you are in good shape -- keep doing what you have been and collecting data. You are now to the point where the management of the offspring becomes important (the 8-12 in. ones that tend to overpopulate).
