Was at Basspro shops today and noticed a new/different kind of measuring device (kinds of pink in color) that you can drop the crappie into and it measures it and tells according to how long it is how old the fish is. 13inch fish said it was 7-8yrs old. How accurate is this? And I have never heard this mentioned before in dissusion by anyone. Anyone may reply please if you have any knowledge of length= yrs/age of fish. thanks

Is that the one with the needle hole built in for various lengths of fish for removing the air from blatters of fish pulled from deep water? Supposed to be opened up wider for large white (thick) crappie to fit into too. Seem it advertised on one of the crappie fishing shows I watched on Youtube.
I don't think it's possible to determine how old a fish is by how long it is. Far too many other variables involved, primarily how much forage is available.
Agreed. Another big factor is the lenght of cold water where the fish is; most southern fish simply grow much faster due to more forage and higher metabilisms? than northern fish sitting under 6-12" of ice 3- 4 months of the yr...read somewhere a 12" crappie in Minnisota is close to 8- 9 yrs old...
What they said on age factor , too many variables over the country.

It was developed by Capps and Coleman.
WAY too many variables involved to determine fish age by length. Growing season, forage, competition etc. can all play huge roles on the growth rate of fish. A 12" crappie in Ga may be 2-3 yrs old where a 12" fish up north could be 8 or 9.
