Good basic study and has the expected results. Many fish feeding studies are difficult to decipher and apply to each particular goal/situation. Some are proprietary (private not peer reviewed) and the results/design can be skewed. You have to factor into any results and decisions your situation and goals. One important factor is the % your fish rely on feed vs natural diet (how supplemental is your feeding). Keep in mind that in most unmanaged waters the biggest cause of poor fish results is not enough food for the fish. With that in mind just about any supplemental food is better than none. The more you rely on feed the more important the quality of the food.
