Have you ever wonder how to know if you have a healthy lake, with healthy bass? Well it's simple, if you bass has a big belly and a normal sized head for the size of it's body than you have a healthy lake!! CONGAULATIONS!!!!
However, if you have an unhealthy lake with rather skinny bass with big heads, than the lake is not very healthy. Chances are, that their bait to bass ration is off, with more bass than bait, not good. > :( :-[
But you can help it! You need to harvest more of the bass that you catch over 1.5lbs, do this until the bass get smaller heads and bigger bodies, you can also help out the lake if you gp to very large healthy river or lake and take some of the blue gill, and, bait fish, and put some into the unhealthy lake, do this and in about a year, you bass will be good and healthy! ;D 8-)
