It may be worth a try, but if I was looking to fatten up res particularly, I would go with a sinking pellet. Mix some in with the floating feed and suspend a net or something near the bottom to catch the sinking ones. I have caught several res on surface flies and some in traps baited with fish feed late this winter/early spring. As a matter of fact, think I will try and find some. Luckily Rangens and Burris are near. Last I tried Rangen, it was too late in the year for them to be making it. They would have to crack a lot of clams to get much protein. Hey, we all like feisty, bloodthirsty redears(chinkypins).
