“…In the freshwater fish tropical gar A. tropicus, prebiotics have been applied where the results are variables with positive, negative, and null effects in the analysis of growth and activity of digestive enzymes (Table 3). Nieves-Rodríguez et al [97] and Cigarroa-Ruiz et al [98], when adding β-glucan in doses of 0.2-2.0%, by 62 and 21 days, respectively, saw no effects on growth. In contrast, the effects on digestive enzymes were different between these studies.…”

Continued human population growth has resulted in increased demand for products, including those derived from aquaculture. The main challenge in aquaculture is producing more every year. In recent years, environmentally friendly supplements that provide the necessary pathways for optimal production have been emphasized. One of them is prebiotics, selectively utilized substrates by host microorganisms conferring a health benefit. Interest in applying prebiotics in global fish farming has increased in recent years as it has been shown to improve growth, boost the immune system, resist stress conditions, and cause the modulation of digestive enzymes. These effects reflect reduced production and disease costs. However, in Latin American countries such as Mexico, large-scale use of these food supplements is needed as a sustainable alternative to improve fish production. This paper gives a review of the current advances obtained with the application of prebiotics in commercially farmed fish worldwide, mentions the prebiotics to use in the aquaculture industry, and updates the status of studies about the used prebiotics in global commercial fish cultivated in Mexico, as well as freshwater and marine endemic fish in this country. Also, the limitations of prebiotics application in terms of their use and legislation are analyzed.

This study aimed to conduct a systematic review and meta‐analysis evaluating the inclusion of β‐glucan in aquaculture animal diets and its impact on their health outcomes. Relevant studies were identified from Scopus and Web of Science databases. A total of 82 primary studies published between 1996 and 2024 were reviewed, of which 70 were included in the meta‐analysis. The results revealed that the application of β‐glucan to aquaculture animal's diets significantly enhanced specific growth rate (SGR; mean effect, g = 2.71; p < 0.001), feed conversion ratio (FCR; g = −3.88; p < 0.0001) and lowered mortality after exposure to pathogens. Likewise, β‐glucan had a positive influence (p < 0.0001) on innate immune parameters (lysozyme and phagocyte activity, NBT, ACH50, and IgM). The study found that the effects of β‐glucans varied among marine and freshwater fish where freshwater fishes (g = 2.05–6.57) exhibit better performance. This study also found a negative correlation between fish's innate immune response and trophic level, suggesting that fish with higher trophic levels may be less efficient at absorbing this bio‐stimulant. Even though there were high heterogeneity (I2 = 73%–97%, p < 0.05) due to the diversity of tested organisms and publication bias, our model and findings are valid. The findings suggest that the dietary application of β‐glucans can have beneficial effects on growth and immune responses especially for freshwater species. The validity of these observations needs to be confirmed by further prospective studies.

Probiotics in aquaculture hold promise for enhancing fish health and growth. Due to their increased specificity and affinity for their host, indigenous probiotics may offer isolated and potentially amplified benefits. This study investigated the effects of Lactococcus lactis PH3-05, previously isolated from adults of tropical gar (Atractosteus tropicus), on the growth, survival, digestive enzyme activity, intestinal morphology, expression of barrier and immune genes, and intestinal microbiota composition in the larvae of tropical gar. Larvae were fed with live L. lactis PH3-05 concentrations of 104, 106, and 108 CFU/g for 15 days alongside a control diet without probiotics. Higher concentrations of L. lactis PH3-05 (106 and 108 CFU/g) positively influenced larval growth, increasing hepatocyte area and enterocyte height. The 106 CFU/g dose significantly enhanced survival (46%) and digestive enzyme activity. Notably, the 108 CFU/g dose stimulated increased expression of muc-2 and il-10 genes, suggesting enhanced mucosal barrier function and anti-inflammatory response. Although L. lactis PH3-05 did not significantly change the diversity, structure, or Phylum level composition of intestinal microbiota, which was constituted by Proteobacteria, Bacteroidota, Chloroflexi, and Firmicutes, an increase in Lactobacillus abundance was observed in fish fed with 106 CFU/g, suggesting enhanced probiotic colonization. These results demonstrate that administering L. lactis PH3-05 at 106 CFU/g promotes growth, survival, and digestive health in A. tropicus larvae, establishing it as a promising indigenous probiotic candidate for aquaculture applications.
