Development of Fishmeal from De-boned Stunted Tilapia Using a Fishmeal Processing Plant

Abstract

Globally the demand for and use of fishmeal has increased rapidly, especially in some of the emerging aquaculture countries in Africa and Asia. In this study, stunted tilapia was processed into de-boned fishmeal. 40kg of freshly harvested stunted tilapia was processed into coarse fishmeal using a compact fishmeal plant (Denmark type: FR-100). The product was further decalcified by sieving out bones and scales and then pulverized. The ratio of fresh weight to finished de-boned weight was 8:1. The de-boned/scaled tilapia fishmeal contained 76% crude protein, 8.0% moisture and 14.0% ash. Stunted Tilapia provides a nutritional and socio-economic resource of great potential benefit that can be brought into the food security chain through a process of using fish as a natural feed for fish.
