“…In this experiment, M. oleifera had a negative effect on the activity of protease in the stomach, while B. amyloliquefaciens addition significantly improved the activity of proteases in the stomach. A marked improvement in the activity of protease was also observed in Apostichopus japonicus fed Bacillus baekryungensis [45]. Probiotics can promote growth by increasing the amount of endogenous digestive enzymes secreted by fish [46].…”

To exploit aquatic animals’ feed resources and functional ingredients and additives, this experiment investigated the effects (a 2 × 2 factorial trial) and mechanism of woody plants and probiotics on Nile tilapia. Each treatment group was randomly assigned triplicate nets of 40 fish (initial body weight of 35.04 ± 0.01 g) in 12 tanks for 56 days. Fish were fed four diets, including a CON–CON diet (with no supplementation) and CON–Ba (basal diet + 1 × 107 CFU/g B. amyloliquefaciens), MO-CON (basal diet + 10% Moringa oleifera) and MO-Ba (basal diet + 1 × 107 CFU/g B. amyloliquefaciens + 10% Moringa oleifera) until apparent satiation (2 meals/day). The results showed that the MO diet had a lower feed conversion ratio than the non-MO diets (P<0.05). The weight gain in the Ba group was significantly higher than those in the groups without Ba treatment (P<0.05). Both MO and Ba improved the morphological indices when applied individually (P<0.05). Ba supplementation improved the activities of digestive enzymes (P<0.05). MO significantly upregulated the gene expression of TNF-α, IL-6, IL-10, and C3 in the spleen of Nile tilapia (P<0.05), while Ba significantly upregulated the gene expression of IL-6 and C3 (P<0.05). The microbiological analyses showed that the abundances of beneficial bacteria increased, and the relative abundances of pathogenic bacteria decreased in fish-fed MO. In conclusion, dietary MO and Ba can effectively improve the immunity of Nile tilapia, while Ba can enhance the activities of digestive enzymes. The synergistic effect of MO and Ba on the intestinal microbiota of Nile tilapia promotes growth, thus showing promising application prospects.

This review aims to advance the development of biofloc technology (BFT), providing more sustainable and efficient practices for the farming of the Japanese sea cucumber (Apostichopus japonicus). BFT is a sustainable aquaculture method that promotes nutrient recycling and effective carbon source management, offering significant advantages such as improving water quality, enhancing growth performance, and boosting the physiological activity and disease resistance of cultured animals. In A. japonicus farming, the optimal carbon source is glucose, and the ideal carbon-to-nitrogen (C/N) ratio ranges between 15 and 20. Microbial additives, such as the Bacillus species, have been shown to enhance biofloc formation and growth, as well as the immune responses in A. japonicus. However, the technology also faces limitations, including finding suitable biofloc culture protocols that match the physiological habits of A. japonicus and potential challenges with biofloc stability under varying environmental conditions. Based on existing research, this review discusses these limitations in the farming of A. japonicus. Additionally, it compares biofloc farming models for other economically important aquatic species. By addressing these key aspects, this review offers insights to enhance BFT performance, ultimately contributing to more efficient and sustainable A. japonicus aquaculture practices.
