Quality Improvement of Water Hyacinth (Eichornia Crassipes) Leaf Meal Fermented with Aspergillus Niger as Fish Feed Ingredient

Abstract

An experiment was conducted to investigate the nutrient quality of water hyacinth leaf meal (WHLM) fermented with different doses of Aspergillus niger as fish feed ingredients. This study utilized a completely randomized design (CRD) with five treatments and three repetitions. The doses of A. niger supplemented in WHLM were 0; 6; 8; 10; and 12%. Results of this study showed that nutrient quality of WHLM with A. niger supplementation significantly affected the reduction of crude fiber and increase of crude protein (P<0.05). Addition of 12% A. niger is the best treatment for improving protein and fiber quality of water hyacinth leaf meal.
