Summary: Using combinations of plant protein concentrates and EAA supplementation, high levels of replacement (50-75% of fishmeal protein) can be achieved in gilthead sea bream without affecting growth performance or quality traits. It was confirmed that 16% replacement of marine protein with plant protein meets the amino acid needs of sea bream. Further investigation is needed to understand tissue-specific and species-specific responses in regulating metabolism due to dietary nutrient utilization.

Summary: Understanding the regulation of food intake in fish is crucial for formulating aquafeeds. This study evaluated the short- and mid-term response of European sea bass fed diets with partial and total fishmeal replacement by defatted Tenebrio molitor larvae meal (dTM). The results showed that dTM replacement did not affect food intake regulation in sea bass, but may lead to long-term changes in intermediary metabolism.

Summary: The aquaculture industry in Norway relies on societal support, but public attitudes are shaped by experiences with industry production, the distribution of benefits and disadvantages, and the availability of information. A nationwide survey showed that the public generally has a positive attitude towards the salmon aquaculture industry, but they had concerns about environmental consequences and economic fairness. Proximity to aquaculture was associated with more positive attitudes, but there were variations within communities. Further research is needed to understand contextual variations and expand on the present results.

Summary: Various studies have shown that using insect meal in aquaculture can reduce land use, but it also leads to greater energy consumption and larger carbon footprint compared to traditional protein sources. Substituting different types of insect meals in aquatic diets can significantly impact solid waste production, with a reduction in marine forage fish required per unit fish yield. Therefore, there is a trade-off when considering the environmental consequences of using insect meal as an aquafeed ingredient.

Summary: Insect proteins, particularly Hermetia illucens meal, have been identified as potential substitutes for fishmeal in aquafeeds. The lipid content and inclusion level of H. illucens meal have significant effects on feed consumption and palatability for fish. The defatted form of H. illucens meal is more suitable than the full-fat type for fishmeal replacement, with an optimal dietary level of approximately 81-104 g/kg for the highest feed intake, growth, unchanged proximate composition, and improved feed utilization by gilthead seabream.
