Growth Rate of Fry

[Bob Martin]

I’ve just been looking at the list of fry-planted high lakes on the WDFW web site. I know that the growth rate of fry in lakes varies and much depends on factors like available food, water temperature, etc. but generally speaking, how many years after planting does it take for fry to grow to catchable size?

Figure on two years to start to get anything resembling something worth catching. At one extreme, where the lake is very productive, the fry planted were reasonably large, and they were planted very early in the season you might get catchable fish by the fall. At the other extreme, if an unproductive lake was stocked late in the season the fry might not get much, if any, growth before the lake becomes ice covered and it might take 3 or more years to start to get catchable fish.

Ebob –

Brian can help me here by perhaps forming a link…you will find data on fish growth in a report I put together that is in the Science section of this TB website.

Here’s the link to the growth report.
