Here is what one of the aquaculture guys that raises bass told me. They were having a problem with fish gaining weight on the fish food they had been feeding for over 20 years the skreeting 42%. Formula had changed with added feather meal. They then switched to the 48% skreeting and the fish began to gain weight as before. The 48% still has fishmeal as the number one ingredient. These are large mouth bass and not hybrid striped bass and so just like eric is saying a totally different type of fish but if the hybrids won't eat the lower percentage food it doesn't matter does it? I hear what your saying eric on the density issue also. We have taken out every catfish caught this year and every crappie under ten inches. I have burned out two electric knives cleaning crappie. We have removed every bass under ten inches. I added 100 pounds of tilapia 100 pounds of bluegill and two hundred pounds of koi. I have also added 100 pounds of crawfish.
