| contents | <p>Trout farming is a significant primary sector activity in Mérida, Venezuela; however, it has experienced a notable decline<br>in recent years, largely due to difficulties in accessing suitable and affordable feed. The formulation of balanced diets for<br>Rainbow Trout (Oncorhynchus mykiss) relies heavily on fishmeal and fish oil as essential raw materials. These ingredients<br>are vital because they offer an optimal amino acid profile and contain Polyunsaturated Fatty Acids, which enhance the<br>Feed Conversion Rate for this carnivorous salmonid species. However, the production of fishmeal and fish oil has been<br>increasingly constrained by stringent regulations on trawling, which aim to address its detrimental effects on marine<br>ecosystems and the competition for food resources among human populations. To address these challenges, several feed<br>formulations have been proposed that theoretically fulfill the nutritional requirements of Rainbow Trout while considering<br>the limitations concerning the inclusion of specific raw materials and the physiological factors pertinent to the species. To<br>aid in the formulation calculations, a computer program named Trout Formulation.exe has been developed. This tool is<br>designed to optimize feed composition in accordance with these nutritional requirements and constraints. As a result, six<br>formulations are proposed that theoretically fulfill the nutritional requirements of Rainbow Trout, utilizing alternative raw<br>materials instead of the two traditional ingredients. These alternatives include Black Soldier Fly (Hermetia illucens) larvae<br>meal reared on fish industry waste substrate, as well as Amaranth (Amaranthus spp.) and Buckwheat (Fagopyrum<br>esculentum) meal. It was determined that while a complete elimination of fish meal and fish oil from the formulation is not<br>feasible—since they play a critical role in ensuring palatability and maintaining the ω6/ω3 balance essential for the proper<br>development of the trout—the formulation incorporating up to 55% Black Soldier Fly larvae meal achieves a theoretical<br>reduction of only 13% in the inclusion of Super Prime fish meal</p> |
