Carl,

One of the great resources on Pond Boss are the Relative Weight Charts.

Below is the link to the archives. (Be sure to scroll down in the thread, most of the oldest links are busted.)

When the experts start talking about your BG being X inches in year 3 and your LMB being Y inches in their year 2, you need a means to relate their growth information to YOUR pond. If you can estimate your number of fish in each category in your pond, you can then use the charts and easily calculate your biomass of each species. Further, you can sum your species to calculate the ratio of predator biomass to forage biomass.


P.S.

The charts are also very helpful to measure the "health" of your pond. If all of your species of predator fish have low relative weight percentages, then your pond has a problem that you need to evaluate and then address.

Hope this helps. Good luck!
