Defatted Tenebrio molitor meal time-dependently altered sensory quality and nutritional value of turbot Scophthalmus maximus during growing-out phase
The yellow mealworm Tenebrio molitor (TM) is promising feed ingredient for aquafeed. However, consumers might reject insect-fed fish unless they know their quality. Nevertheless, reports on how TM influences fish quality were rare and yielded conflicting results; furthermore, there are no evaluation...

The yellow mealworm Tenebrio molitor (TM) is promising feed ingredient for aquafeed. However, consumers might reject insect-fed fish unless they know their quality. Nevertheless, reports on how TM influences fish quality were rare and yielded conflicting results; furthermore, there are no evaluations on quality of turbot Scophthalmus maximus fed TM.

Dietary TM optimized the health value of muscle fatty acids regarding thrombogenicity index, atherogenicity index, and hypocholesterolemic to hypercholesterolemic fatty acids ratio but linearly decreased the muscle contents of hydroxyproline, collagen, and n-3 PUFA.
