Most if not all the negatives about LCS in the Illinois LCS study could also be applied to the habits of BG or RES.
1. Abundance is important in prey selection. Thus when BG (in cited study) are many times more abundant it stands to reason that LMB would consume more BG than LCS. Both test lakes were pretty weedy with milfoil. Results may vary significantly under different habitat conditions. Laboratory conditions with no weeds did indicate the LMB preferred (consumed) LCS "far more often" over BG. Similar studies with low or no weeds and with other predators also reveal similar results (preference for a soft rayed fusiform vs BG).
2. Antipredatory behavior. Different species of predators behave differently so antipredatory behavior for LMB may not cause the same results with a different species of predator.
3. 7.8" fish are excluded form predators. Compare the body depths of a BG and LCS at 7.8" long. LCS normally grow to 7.8" size slower than BG, although first yr growth of LCS is fairly rapid. Earier spawning predators than LMB may see more benefit of LCS fry that LMB.
4. Difficult of maintain where predators are abundant. Most all preyfish have this feature.
5. Little change in diet & growth of LMB when introduced to an established LMB-BG lake. What if in test lake LMB were already growing at a relatively good rate?
6. BG at least on this site are often suggested to be stocked and allowed to spawn 1 yr in advance of adding LMB similar to that suggested for LCS.

This was only one study. Be careful when drawing too many conclusions from one study.

BG too will become overabundant in weedy ponds. BG can consume some of the same foods as small LMB (diet overlap) and compete at least on some level with the bass. LCS were noted to have minimal diet overlap with YOY LMbass. There is probably no perfect forage fish. Almost every pond owner has somewhat different goals and definately each has a DIFFERENT type of water body even on the same "ranch", thus they should incorporate and use somewhat different techniques to achieve those goals. That is what this site and Pond Boss magazine is for - teaching and helping provide information for producing better pondmeisters and better fisheries.

IMO the biggest negatives to LCS is they are not angler worthy nor good eating. IMO LCS would be most beneficial in ponds where BG are not desired or to use them as a supplimental forage species (diversity) for LMB or other types of predators.

If one does not want BG and yet wants to grow some decent sized predators including LMB, what are their options? There aren't very many, at least really good ones. The LCS increases the options and choices. Actually only a very small amount of research has been done with LCS. Obviously the more common they become the more research that will occur and more good information (+ & -) will result.

I think I speak for CJS2003 and myself that our apparent enthusiasm was not that these LCS were a panacean, magic bullet fish but our joy was that a relatively unknown and new, versatile forage fish will hopefully soon at least become available as a hatchery farm raised fish. Again I commend Todd Overton for taking the initiative spirt to work with and try to raise these fish.
