Abstract

We conducted a 12week feeding trial to evaluate the effects of total fishmeal replacement with different corn coproducts on growth performance feed utilization efficiency and body composition in juvenile Nile tilapia Oreochromis niloticus Five isonitrogenous diets were prepared Fifty percent of the dietary protein was obtained from fishmeal control diet or from one of four corn coproducts experimental diets namely corn protein concentrate corn gluten meal highprotein distillers’ dried grains HPDDG or distillers’ dried grains with solubles DDGS Fish with an initial mean weight of 45 g were fed one of the five diets twice a day to near satiety Significantly higher P  005 specific growth rates and survival occurred in the fish fed the control diet or DDGS followed by those fed the HPDDG mean feed intakes by fish in these three groups were significantly greater than those in the others Food conversion ratio protein efficiency ratio and total amino acid content of the whole body were not affected by changes in dietary ingredients Wholebody and fillet protein contents were highest in the HPDDG group whereas the lipid content was highest in those fed DDGS DDGS can be used to fully replace the fishmeal components of Nile tilapia dietsThe Scholarship received by the first author from the Ministry of Education Culture Sports Science and Technology MEXT of Japan for her doctoral degree is gratefully acknowledged This study was partly funded by a GrantinAid for Scientific Research given to Shuichi Satoh from the Ministry of Education Culture Sports Science and Technology through the Japanese Society for the Promotion of Science 26252034 and the “Development of Aquaculture Technology for Food Security and Food Safety for the Next Generation” project of the SATREPS program of JST and JICA
