“…The benefits of dietary supplementation of nucleotides on fish reproduction and positive effects have been reported for female (Gonzalez Vecino, 2005;de Lima et al, 2020) and male fish (Bombardelli et al, 2023). In this case, dietary supplementation ensures the supply of nucleotides to breeders under conditions of high metabolic demand.…”

“…These demands are unlikely to be met by natural sources present in conventional feeds (Li and Gatlin, 2006;Hess and Greenberg, 2012;Hossain et al, 2020). Furthermore, feeding tilapia breeders with diets containing purified nucleotides does not have deleterious effects on fish health, maintaining adequate hematological parameters (De Lima et al, 2020;Bombardelli et al, 2023).…”

“…Males and females (1:3) underwent reproductive management in the hapas, remaining 12 days apart with five days of mating (de Lima et al, 2020). At the end of the mating period, the eggs were collected and incubated as described by Bombardelli et al (2009Bombardelli et al ( , 2017.…”

“…Moreover, nucleotides are responsible for modulating liver metabolism and improving nutrient absorption by enterocytes in the intestine, thereby improving the utilization of nutrients from the feed for animal development (López-Navarro et al, 1995). Research on the addition of nucleotides to fish diets has yielded positive results, promoting greater animal growth (Li and Gatlin, 2006;de Lima et al, 2020), improvements in stress and immune systems (Barros et al, 2015), gastrointestinal health (Li and Gatlin, 2006), increased digestive enzyme activity (Zou et al, 2016), and benefits for the health of breeders (de Lima et al, 2020;Bombardelli et al, 2023). Furthermore, it is suggested that nucleotide supplementation may be important for nutritional interaction between broodstock and offspring.…”

In this study, the effects of adding nucleotides to diets for broodstock and offspring of Nile tilapia (Oreochromis niloticus) were evaluated. Nile tilapia broodstock were fed diets containing 0.0, 2.5, and 5.0 g of Ascogen®/kg for five months. After this period, the eggs were collected and incubated. The offspring, at five days of age, were fed diets containing 0.0, 2.5, 5.0, and 7.5 g of Ascogen®/kg for 100 days. Analyses of digestive enzyme activity and the morphology of hepatic and intestinal tissues of juveniles were conducted. An interactive effect (p<0.05) between the diets of broodstock and offspring on trypsin activity was observed. The highest activity of this enzyme was recorded when diets containing 2.5 g/kg were used for broodstock and 7.5 g/kg for offspring. Juveniles from broodstock fed with 0.0 g/kg and offspring fed with 7.5 g/kg showed a significantly greater (p<0.05) height of enterocytes. Hepatic tissue was not influenced by the diets regarding its morphology. It is concluded that 7.5 g/kg of Ascogen® in offspring's diet promotes alterations in intestinal morphology in terms of enterocyte height. Under this condition, when associated with 2.5 g/kg of Ascogen® for broodstock, it enhances trypsin activity in the offspring.

“…Constantine et al, 57 found a decline in fecundity and fertility, vitellogenin, and hatching success rate in zebrafish (Danio rerio) exposed to ibuprofen at environmentally relevant concentrations. de Lima et al, 58 found that certain diets used to reduce oxidative stress in the human population could interfere with the reproductive process and growth in female Nile tilapia (Oreochromis niloticus). Godoi et al, 59 found a significant reduction in reproductive activities by reducing 17β-Estradiol (E 2 ), and testosterone levels in male fish (Astyanax altiparanae) exposed to common drugs (Diclofenac (DCF) and caffeine (CAF) at normal levels.…”
