“…These results may both be supported by the fact that zebrafish possess specific chitinases able to digest chitin (with a gene expression dependent on BSF meal inclusion level) or by the anti-inflammatory, antibacterial and antiviral properties of medium-chain fatty acids (especially lauric acid, C12) which are particularly abundant in the BSF-based diets used in this study 47–49 .…”

Intensive fish farming relies on the use of feeds based on fish meal and oil as optimal ingredients; however, further development of the aquaculture sector needs new, nutritious and sustainable ingredients. According to the concept of circular economy, insects represent good candidates as aquafeed ingredients since they can be cultured through environmental-friendly, cost-effective farming processes, on by-products/wastes, and many studies have recently been published about their inclusion in fish feed. However, information about the physiological effects of insect-based diets over the whole life cycle of fish is presently missing. At this regard, the present study investigated, for the first time, the effects of Black Soldier Fly based diets (25 and 50% fish meal substitution) administration for a six months period in zebrafish ( Danio rerio ), from larvae to adults. A multidisciplinary approach, including biometric, biochemical, histological, spectroscopic and molecular analyses was applied. Aside a general reduction in fish growth and lipid steatosis, six-months feeding on Black Soldier Fly based diets did not show major negative effects on zebrafish. Gut histological analysis on intestine samples did not show signs of inflammation and both stress markers and immune response markers did not show significant differences among the experimental groups.

The Future of Aquatic Protein: Implications for Protein Sources in Aquaculture Diets

et al. 2019

Approximately 70% of the aquatic-based production of animals is fed aquaculture, whereby animals are provided with high-protein aquafeeds. Currently, aquafeeds are reliant on fish meal and fish oil sourced from wild-captured forage fish. However, increasing use of forage fish is unsustainable and, because an additional 37.4 million tons of aquafeeds will be required by 2025, alternative protein sources are needed. Beyond plantbased ingredients, fishery and aquaculture byproducts and insect meals have the greatest potential to supply the protein required by aquafeeds over the next 10-20 years. Food waste also has potential through the biotransformation and/or bioconversion of raw waste materials, whereas microbial and macroalgal biomass have limitations regarding their scalability and protein content, respectively. In this review, we describe the considerable scope for improved efficiency in fed aquaculture and discuss the development and optimization of alternative protein sources for aquafeeds to ensure a socially and environmentally sustainable future for the aquaculture industry.

“…in partial replacement (15 or 30%) of fish meal protein, finding a worsening of fish performance (growth, feed intake) at the highest percentage of replacement. The use of a blend of Tisochrysis lutea and Tetraselmis suecica dried biomass replacing 15, 30 or 45% of fish meal protein in diets low in fishmeal content in European sea bass produced no effects on fish growth despite the decline in feed digestibility (Cardinaletti et al 2018). Palatability and nutrient bioavailability is strictly dependent of the microalgal species as it is hampered by the high complexity of their cell walls, which may introduce anti-nutritional factors and may harm the intestinal tract and result in inflammation and reduced nutrient uptake in fish species.…”

“…Arthrospira (Spirulina) can be included as a protein source into the diets of ruminants, pigs, poultry, and rabbits (Holman and Malau-Aduli 2013). Several studies showed the use of algae as viable alternatives to fish meal and fish oil (Gouveia et al 1997;Palmegiano et al 2005;Kiron et al 2012;Tulli et al 2012;Qiao et al 2014;Tibaldi et al 2015;Sarker et al 2016;Cardinaletti et al 2018). Over the last years, the use of microalgae and seaweed for the development of novel products, as well as for obtaining high-added value compounds, has attracted much interest from both food and pharmaceutical industries (Barba 2017).…”

The expected future demand for highly nutrient animal food products will push the animal production system to search for new sources of high-quality protein feedstuffs. In this scenario, economic and environmental issues will have to be considered while reducing the competition with the plant-based human food chains. Legume grains and some oilseed cakes, by-products from the oil industry, are the main protein sources for ruminants and terrestrial monogastrics such as pigs and poultry. Their relevant role will hold in the next decades, but it is necessary to increase the diversification of sources that can be grown profitably throughout the world, including European countries. Microalgae are a promising source of protein and other nutrients for animal feeding. However, an amazing richness of biologically active substances makes these organisms very interesting as feed ingredients, as their role go far beyond the supply of nutrients. Due to the limited usage of microalgae as human foodstuffs or food ingredients, low competition between microalgae-based feed and food chains is predictable. This review aims to synthesise current knowledge on minor pulses and other protein-rich plant products and microalgae, as alternative ingredients to the conventional animal protein sources, focussing on their production, availability, and nutritional values. Points of strength, weakness, opportunity and threat related to the use of these protein sources in animal feeding are separately analysed through a SWOT approach to underlie future needs in terms of research and/or technological development that could help valorise these nutrient sources as feed ingredients.
