“…Several studies have demonstrated that seaweed inclusion levels of up to 20% can effectively replace fishmeal in tilapia diets without compromising the growth performance and feed utilization [40,41,43,48,50,73]. Similar outcomes have been observed in other fish species as well [74][75][76].…”

Tilapia are important aquaculture species worldwide, and their production is heavily reliant on feed, therefore individual studies have been conducted to investigate the effects of soybean and seaweed-based diets on tilapia, but a comprehensive understanding of their impact on growth performance, feed utilization, and gut microbiota is lacking. This review aimed at evaluating and synthesizing the existing literature on the effects of soybean and seaweed-based diets on growth performance, feed utilization, and gut microbiota. A systematic search of databases was conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 24 studies were included in the meta-analysis, and the results showed that soybean-based diets improved specific growth rate (SGR) with an effect size of -2.14 (95% CI: -2.92, -1.37; p < 0.00001; I2 = 99%). However, soybean-based diets did not improve the feed conversion rate (FCR), as the effect size was 1.80 (95% CI: 0.72, 2.89; p = 0.001; I2 = 100%). In addition, the seaweed-based diets did not improve the SGR, as the effect size was -0.74 (95% CI: -1.70, 0.22; p = 0.13; I2 = 99%). The same results were verified for the FCR, where the effect size was -0.70 (95% CI: -1.94, 0.54; p = 0.27; I2 = 100%). In this review, no study on the effect of soybean and seaweed-based diets on the gut microbiota of tilapia met the inclusion criteria, but studies carried out on other farmed fishes showed that soybean and seaweed-based diets improved the growth of beneficial gut microbiota. The findings of this study suggest that soybean and seaweed-based diets can contribute to the sustainability of the aquaculture industry by reducing reliance on fishmeal and fish oil.

This study was done to appraise the effects of the combination of dietary Gracilaria pulvinata and Sargassum ilicifolium on growth, immunity, and fatty acid profile in Asian seabass (Lates calcarifer). A total of 540 juveniles (36.06 ± 0.05 g) were stocked into eighteen 200 L tanks and divided into six experimental treatments, each in triplicate. Fish were fed diets containing 0 (control), 3% (SW3), 6% (SW6), 9% (SW9), 12% (SW12), and 15% (SW15) mixtures of both seaweeds powder in equal proportions (1 : 1) for 56 days. There was no improvement in weight gain parameters. Serum lysozyme and peroxidase activities in SW9 and SW12 treatments were significantly higher in compare to other treatments. The highest activities of skin mucus lysozyme, alkaline phosphatase, and total protease were observed in the SW12. Liver igf-1, il-1β, il-8, and lysozyme expression showed a rising trend up to SW9 and then decreased. Liver antioxidant enzymes activity and glutathione content showed a similar pattern of changes. Liver total antioxidant capacity was highest in the SW9 treatment, while the lowest value of liver malondialdehyde was observed in the 12% seaweed treatment. The amount of total n‐3 polyunsaturated fatty acids, especially docosahexaenoic acid, was higher in the SW12 and SW15 treatments in compare to others. Our findings suggest that adding 9%–12% of Gracilaria and Sargassum seaweed powder to the diet improves serum and mucosal immunity, antioxidant status, and fatty acid profile in L. calcarifer juveniles.
