This work reviews the use of alternative plant, microbial and insect protein sources, evaluating in particular their impact on growth, nutrient digestibility, fillet quality traits and sensorial perception in the most important farmed marine and freshwater fish species. The Brief specifically summarizes the pros and cons of plant oils from oilseeds, which can on the one hand be a sustainable substitute for fish oil, but which are on the other hand less rich in omega-3 long-chain polyunsaturated fatty acids. The feeding might therefore result in an undesired reduced nutritional value of the flesh of farmed fish.The authors also explore the possible use of fishery discards as potential aquaculture feed source. Since the landing of by-catch will with the new Common Fisheries Policy (CFP) become obligatory (instead of simply returning it to the sea, often dead), suitable uses of what must not be used for human consumption can be investigated. The authors give an outlook whether this might become a sensible alternative to improve the management of discards and create more sustainable fisheries.
The Brief also addresses the issues of additives to aquafeeds, such as vitamins, minerals, and antioxidants, but also immunostimulants and enzymes. The authors discuss which effects these additives may have on fish growth, welfare, reproduction and health status in aquacultures.
Francesco Gai is a permanent researcher at the Institute of Sciences of Food Production, National Research Council, Grugliasco, Italy, where he studies the animal nutrition of monogastric species with a special focus on aquaculture. Francesco Gai obtained his PhD degree in Animal Productions (2006) at the University of Turin, Italy, and since 2012, he is involved in experimental projects on the utilization of insects for feed purposes, in partnership with different European research groups.
Giulia Maricchiolo obtained her PhD degree in Anatomy of Fish species and Birds at the Faculty of Veterinary of University of Messina (Italy), and she is a permanent researcher at the Institute for Coastal Marine Environment (IAMC) of the National Research Council, Messina (CNR, Italy). Giulia Maricchiolo is responsible for the Aquaculture facility of IAMC-CNR - a structure authorised for Animal experimentation (in accordance with the Legislative Decree No 26/2014) by the Italian Ministry of Health, and for the Animal Welfare structure of the IAMC-CNR. She is also President of the Organism Responsible for Animal Welfare in the same institution.
Lucrezia Genovese is currently a Senior Scientist of the Institute for Coastal Marine Environment (IAMC) of the National Research Council
Sergio Ragonese is a senior fisheries biologist involved in the fields of assessment and management of wild living stock exploited mainly by the Mediterranean bottom trawl fisheries. He works at the Italian National Research Council, Institute for Coastal Marine Environment, Mazara del Vallo, Italy. Due to his activity, he can be considered as a 'fisheries cleaner', i.e., a scientist who analyses both historical and current fisheries literature. The work conducted by Sergio Ragonese aims at highlighting anomalies and contradictions (if any) in the developed life history pattern, paradigms of the exploited stock and corresponding assessment and management plans proposed to recover and rebuild fishable resources.
Teresa Bottari is a permanent researcher at the Institute for Coastal Marine Environment (IAMC) of the Italian National Research Council (CNR), Messina, Italy. She studied the health of marine environment, fish pathology and quality during her PhD graduation, and has participated in the following projects: MEDITS - evaluation of demersal resources in the Mediterranean Sea; CAMPBIOL - monitoring of commercial catches; and RITMARE - Use of fish parasites as biological tags for stock discrimination. Currently, Teresa Bottari is author of 40 scientific articles on stock assessment and management of demersal resources and marine parasitology.
Gabriella Caruso is a Researcher at the National Research Council, Institute for the Coastal Marine Environment (IAMC-CNR) of Messina (Italy) since 1994. Her research activity focuses on aquatic microbes and their role in carbon and phosphorus biogeochemical cycles, as well as on microbial pollution detection methods. Her expertise also includes animals' welfare with respect to fish digestive physiology and immune system and environmental monitoring of aquaculture sites. Involved in several national and international research programs, she was qualified as a Full Professor in Ecology in 2014. Gabriella Caruso has been involved in different academic activities, including membership of the Executive Plankton and Aquaculture Committees of the Italian Society for Marine Biology (SIBM). She has served as a Referee and Editorial Board member forseveral international journals, and Guest Editor for a Special Issue of The Open Marine Biology Journal.
