Effect of Dietary Supplementation of Peeled Black Soldier Fly for Eel Anguilla Japonica

Abstract

The purpose of this research is to evaluate the effect of dietary supplementation of peeled black soldier fly (PBSF) powder on growth performance and survival rate under a stress test of the young eel Anguilla japonica. The diets were added with graded levels of PBSF powder by 0, 2 and 4% (designated as Con, PBSF2 and PBSF4 respectively). triplicate group of Young eel were hand-fed with one of the diets one times daily for 28 days. The survival of young eel exposed to anaerobic in a stress test was significantly higher in eel group fed PBSF2 and PBSF4 than that of eel fed the control diet. Growth performance of the eel were higher with the dietary PBSF2 than Control and PBSF4. Results indicated that dietary PBSF powder could be used as a functional supplement for improvements in stress resistance in young eel. The suggested dietary inclusion level of PBSF is approximately 2% for the eel.
