Rangen has a production facility in Angleton, just south of Houston, Texas. From what I could tell, their rainbow trout mix looks like it would put weight fast on BG, as it is high in protein and fat.
Don't know how costs compare with Aquamax, but if it is all comparable that would be a big plus. Always good to have competition.
Still would like to hear more about the new stuff in Pennsylvania that enhances fish growth, eating, and even life expectancy.
