Aqua You can remove the fins from small bluegill to make them easier for your LMB to eat. You will need to keep in mind that bass can normally only eat bluegill up to 1/3 of their lenght.Most pond managers recommend taking out 20 to 40 lbs per acre of LMB a year and four times that weight in BG each year to maintain a balanced pond. You will need to monitor the relative weights of your fish to gauge growth of your LMB and BG. The most cost effective way to add weight to your LMB is to feed your forage fish a good quality fish food.Some feeds provide close to a 2:1 conversion rate for forage fish. A quality bag of fish food will usually cost around $50 for a 50# bag. That 50# bag will add 25# of weight to your bluegill. It normally takes 10# of BG for a LMB to gain 1lb.When feeding forage fish you have to keep in mind that fish are mostly made up of water so your net gain may be minimal
