My SMB , BG, and YP have been stocked , coming up on 3 years soon. The thought a couple nights ago was " is their weight or length where it should be for their age ". In reflection , is this the wrong question ? Too many variables from BOW to BOW ? Also not knowing their true age when received from the fish dealer . The real question is, are my fish at a healthy weight for their length ? If RW is at 85-115 % then forage has been there, through out its life so far , water has been reasonably happy , if weight and length RW is there then I should be happy with growth , for time they've been residents in my pond.. Forget how old, compared to any bench mark, and be happy with healthy fish, and healthy fish are those within a reasonable % of RW ? Fish at what ever age, are growing at the proper speed for that fish, in that BOW, at that Latitude , at that elevation if it is close to 100% on RW Scale ? Next question, I have not seen a RW scale for Okla. , with RW being taken with a grain of salt, but a good tool , if my fish match up to the RW for Pa. , is this close enough ? Within 2 or 3 % ? Sorry if ridiculous question , still solidly a guppy, a guppy that is struggling to make his RW %.
