Abstract

Animal feed manufacturing involves the use of a variety of raw materials to produce compound feeds. The feeds are defined according to certain specifications with regard to nutritive composition based on specified descriptions for nutritional, hygienic and physical quality. The black soldier fly larvae can be the best ingredient to replace fishmeal in the fish feed formulation since the protein content is higher and it is easy to breed and manufacturing cost of the feed can also be reduced. This study was conducted to formulate Tilapia fish feed pellets by using black soldier fly larvae as an alternative to replace fishmeal ingredients. There were nine extruded diets containing various ratios of black soldier fly larvae and tapioca starch (48:19, 37:29, 27:38) and varying moisture contents of 20%, 30% and 40% were formulated. Floating fish feed pellets were produced by using a single step technique called cooking extrusion by using a single screw extruder. The barrel temperature profiles were set at 80, 100 and 120 °C while the die temperature was set at 160 °C. The quality properties of extruded diet in terms of expansion ratio, hardness, floatability, water solubility index, water absorption index, and sinking velocity were evaluated. The results showed that increasing moisture level of diet from 20% to 40% increased the value of expansion ratio, water absorption index, floatability, and sinking velocity. The best moisture content level in feed pellet to produce best floating extruded feed was by using black soldier fly larvae with 40% moisture content. Tapioca starch was used as a binder for the formulation of black soldier fly larvae. Floatability of pellets depends on the amount of the tapioca starch added during the extrusion process. Thus this study provides an opening for further development of Tilapia fish feed pellets for better economic and nutritional advantages.
