EXTR 400. This diet has been used very successfully in the Tilapia industry where the fish are reared in a closed rearing, biological recycle system. The nutrient dense diets allow less food to be fed but still maintain a rapid growth response. The reduced feed allotment helps keep the biological filters working better and with less possibility of an overload.
EXTR 350. Rangen's premium warm water diet is formulated to promote maximum growth rates under highly intensive culture conditions. The extrusion technology employed during the manufacture of this diet results in a durable pellet resistant to leaching of water-soluble nutrients. Calculated Analysis.......................%
