Efstratios Roussos is undertaking a research stay with the Nutrigenomics group at IATS-CSIC2025-05-26
Efstratios Roussos, predoctoral student from the Hellenic Centre for Marine Research (HCMR) in Athens (Greece), is currently working in the Nutrigenomics and Endocrinology of Fish Growth group at IATS-CSIC.
His stay is part of a TNA project funded by the European AquaExcel 3.0 program, entitled “Evaluation of the effects of fishmeal substitution with black soldier fly (Hermetia illucens) larvae meal in diets on European seabass (Dicentrarchus labrax) metabolism and gut health”. This research aims to evaluate the potential of black soldier fly (BSF) larvae meal – produced experimentally using plant-based waste substrates that support a circular economy – as a fishmeal replacement in the diet of European sea bass. His work at the IATS aims to investigate the effects of those diets, including different proportions of such insect meal, on the expression of particular genetic markers of interest in liver and anterior gut in European sea bass. Ultimately, this study seeks to identify the maximum inclusion level of defatted BSF larvae meal that can replace fishmeal in the diet without negatively affecting growth performance or overall metabolism, and to investigate the main physiological mechanisms involved.
