“…A recent study at our laboratory indicated that the same fermented SFM with ATCC PTA-6737 could not be fed more than 20% of the compound feed of young growing Carp (Cyprinus carpio) (Yigit et al, 2017). This results was in good agreement with other results reported elsewhere (Soltan et al, 2015;Hassaan et al, 2018;Jannathulla et al, 2018), where the SFM fermented with Bacillus subtilis can be fed to the fish and shrimps up to 25% and 5% of total diet, respectively.…”

“…A recent study showed that fermentation of SFM for the purpose of pig and poultry nutrition resulted in improved nutrient content (particularly increased protein and degraded crude fiber) and reduced dietary ANFs (Poulsen and Blaabjerg 2017). Nutritionally enriched SFM fermented with yeast and Bacillus subtilis in SSF process was even successfully incorporated up to 25% into a compound fish diet (Soltan et al, 2015;Hassaan et al, 2018). Moreover, the diets of shrimps could be added up to a 5% inclusion of fermented SFM with fungal microorganism (Jannathulla et al, 2018).…”

Sunflower meal with 3 mm particle size (SFM) with 66 or 80% moisture content was inoculated with 1x107 cfu (colony forming unit/g) of Bacillus subtilis ATCC PTA-6737 and fermented for 0, 24, 48 and 72 h. The pH was increased from 5.75 to 9.1 of SFM fermented at both moisture levels with no significant changes in organic acid production. The bacterial growth was peaked at 24 h. Dry matter and crude fibre contents of SFM decreased by 10-13 and 18%, respectively. In contrary, the amount of crude protein, crude ash and soluble amino acid nitrogen increased by 36, 61% and 145%, respectively, with no regard to the effect of moisture content. Phytic acid was degraded up to 42% at both level of moisture content. In conclusion, SFM was enriched with ash and protein and lowered in fibre and phytic acid contents, and can be used as alternative feed material in animal nutrition.

“…niloticus metabolized yeast‐fermented FW similarly to other traditional aquafeed ingredients. Similar results were obtained with Soltan et al (2015) and Hassaan et al (2018) who offered juvenile Nile tilapia diets containing yeast‐fermented sunflower meal as replacement of FM. However, in the present experiment, a significant increase in body ash proportions was observed among fish offered diets 5, 6 and 7 (30, 35 and 40% FWY, respectively) as compared to control fish.…”

Aquaculture contributes more than half of global seafood production (FAO, 2018), and most of aquaculture today relies on manufactured feeds (FAO, 2020). Aquafeeds generally contain between 30% and 50% proteins, as most aquatic animals require substantial amounts of proteins to grow well (Kaushik & Hemre, 2008;Rombenso et al., 2021). However, feed ingredients rich in protein such as fishmeal (FM) are expensive and non-sustainably produced (Dersjant-Li, 2002), and land-based substitutes are not as environmentally friendly as we wish (Malcorps et al., 2019). Accordingly, finding sustainable and inexpensive but nutritious sources of protein is necessary if the industry is to continue to grow.Food loss and food waste constitute a major challenge for humans, mainly because of their impact on the environment and on food security. More than 850 million people around the world suffer from long-term undernourishment (Buckle, 2015), yet nearly a third of the world's food is lost or wasted every year. The food waste (FW) part is related to consumers' behaviour and is food wasted specifically at the end of the supply chain (Parfitt et al., 2010), such as postconsumer food waste. Post-consumer FW is comprised of all food that is left unconsumed, such as household food waste and restaurant plate leftovers . Such food waste is a good source of nutrients and can substitute major aquafeed ingredients (Wong et al., 2016). However, FW is not a complete source of nutrients for fish as the waste lacks certain vitamins and minerals,

“…Furthermore, the crude fibre levels of aquafeeds should be below 7% for accessibility of nutrients by digestive enzymes 98 . However, higher levels of crude fibre percentage were reported in experimental diets of O. niloticus and L. rohita (Hamilton) which could have resulted in poor FCR 99–101 . Hence replacement of FM with FPPS should be carefully done to maintain the crude protein levels within the recommended levels of the aquatic animal, and also, fermenting microbes and fungi should be carefully chosen for efficient reduction of crude fibre contents in FPPS.…”

In the aquaculture feed industry, fishmeal is widely used as a source of animal protein due to its high palatability, excellent amino acid profile and increased digestibility.However, the incorporation of fishmeal in aquaculture diets increases the costs of production due to the declining wild fish stocks hence an urgent need to search for sustainable and cheaper alternative protein sources. The use of fermented plant proteins as substitutes for fishmeal in aquaculture diets has recently gained attention due to their improved nutritional quality, easy availability and low costs. Therefore, a systematic review and meta-analysis were conducted to quantify the effects of fermented plant proteins as substitutes for fishmeal on the growth performance, feed utilisation, survival, antioxidant, metabolic and digestive enzyme activity of several aquaculture species. Results of the meta-analysis indicated that replacement of fishmeal with fermented plant proteins in aquaculture diets enhanced the growth performance, feed utilisation, antioxidant and digestive enzyme activities of several aquaculture species regardless of experimental duration and source of fermented plant protein. Likewise, metabolic enzyme activity (i.e., Alanine aminotransferase and Aspartate aminotransferase) was reduced in experimental dietary treatment groups relative to the fishmeal control groups. To elucidate the influence of moderators on the observed effect sizes, a mixed-effects model was conducted and the results indicated that fishmeal substitution levels and aquaculture species influenced the observed effect sizes in both antioxidant and digestive enzyme activity. No significant differences were noted in survival between the experimental dietary treatment groups and fishmeal control diets among all aquaculture species. However, carnivorous marine species exhibited lower values for specific growth rate and protein efficiency ratio in experimental dietary treatment groups compared to the fishmeal control diets. Likewise, freshwater species exhibited poor FCR values in experimental dietary treatment groups relative to the fishmeal control diets. Overall, the replacement of fishmeal with fermented plant proteins in aquaculture diets is a safe and viable solution for increased and sustainable aquaculture production.
