    The aquaculture sector is steadily growing due to the increasing demand for healthy and cheap animal protein sources. Consequently, the high demand for nutritionally balanced aquafeed increases, but requires sustainable and feasible feed ingredients. However, the high cost of fish and soybean meals opens the door to looking for suitable non-traditional feed ingredients. The processing of fruits results in high amounts of waste and by-products, which are risky for the environment but rich in nutritional value. Recycling fruit waste in aquafeed is successfully applied and results in high growth performance, productivity and well-being of aquatic animals. Fruit byproducts are also potential functional feed additives devoted to their high content of polyphenols, flavonoids, vitamins, minerals, polysaccharides and peptides. As functional components, fruit by-products enhance the antioxidative and immune responses of aquatic animals and increase their tolerance for biotic and abiotic stressors. In light of reducing antimicrobial chemicals in aquaculture to mitigate antimicrobial resistance, dietary feed additives extracted from fruit by-products can be used as eco-friendly substances. The investigations involved in evaluating the incorporation of fruit by-products and their derivatives in aquafeeds are explored in this review. An overview of the possibility of using non-traditional plant products in aquaculture as a feasible and sustainable concept is addressed in this review. Academic knowledge with enough information for more development and research to maximise the utilisation of fruit by-products in the aquafeed industry is also enriched.

    Probiotic application for sustainable aquaculture
    (Wiley Publishing Asia Pty Ltd, 2018-06) Mahmoud A.O. Dawood; Shunsuke Koshio; Mohamed M. Abdel-Daim; Hien Van Doan
    Aquaculture, which constitutes one of the largest food production sectors in the world, is preferably practiced with natural organic products rather than with synthetic chemicals or antibiotics. In addition to the daunting challenge of providing food and livelihood to the exponentially increasing world population, the aquaculture industry is key to ensuring that development is based on environmentally sustainable practices, specifically in the production of aquafeeds. Terrestrial microorganisms that act as natural defence systems of cultured species have been identified as the main producer for the beneficial bacterial candidates. Probiotics have recently gained popularity as beneficial microbes candidates in cultured organisms to maintain the health condition and well-being of different aquatic animals. This review aimed to understand the necessity of using probiotics as a sustainable alternative to regulate the growth performance, feed utilisation and general health condition for sustainable aquaculture. Also, explanatory discussion about the host microbiota and its ability to produce different probiotic strains and the probiotic functionality to ameliorate the host immunity to provide the interactive effects on the host-derived probiotics. By presenting the results obtained from the previous studies about the ability of probiotics to sustain the aquatic animal’s performances, this study condensed the current knowledge and information for future research and development of the probiotic application in aquaculture.
