Physiological responses of juvenile barramundi, Lates calcarifer (Bloch, 1790) when fed bioprocessed plant base diets

Abstract

This research evaluated nutritional compositions of the selected and bioprocessed plant ingredients and their potential to replace fishmeal in barramundi (Lates calcarifer) diets. Bioprocessing including fermentation, germination and enzymatic treatments improved the nutritional profiles of the plant ingredients that were reflected in the enhanced growth and physiology of the barramundi fed the test diets with less fishmeal based protein source. Further, the inclusion of the test diets improved the water quality of the rearing environment.
