All my foolish error!

I foolishly just added fish. I should have done an elementary survey of the Pond. I have not paid attention nor done much fishing the past few years, so I thought. Looking at past records it has been TEN years & the pond has drastically changed. The relative weights of the LMB are now 75% & below. I now understand that I have a skinny fishpond that must be rebalanced before any real changes will happen. I was just feeding some hungry fish a tilapia dinner. Once the relative weights are more near normal, I will re-formulate a new plan.
