... The results revealed an up-regulation of antioxidant enzymes such as SOD, CAT, and GPx and a downregulation of MDA levels. This potential is thought to be due to compounds with scavenging activity such as carotenoids or phenols, which have a high affinity for ROS, they can neutralize by their own oxidation Rouhani et al., 2022). Mildenberger et al. (2022) quantified the TPC and the antioxidant capacity of Saccharina latissima. ...
... Besides, we recommend exploring other ingredients like betaine, dietary seaweed (Dictyota dichotoma), dietary dragonhead fish, and Myristica fragrans (nutmeg) alongside probiotics in future studies. These readily available ingredients have already shown promise in improving fish growth, stress tolerance, and immune response, making them worthy candidates for further investigation against temperature stress (Heshmatfar et al., 2023;Mahmoudi et al., 2022;Musavi et al., 2022;Safari et al., 2022bSafari et al., , 2022aVakili et al., 2023). ...

The increasing human population has led to an increase in the demand for animal proteins and as such, efforts have been put in place to increase their production to satisfy the growing food demand (Singh, 2021;Li et al., 2022;Safari et al., 2022). Aquaculture is the fastest-growing food production sector across the globe contributing 52 % of animal protein for human consumption (Tacon, 2020;Li et al., 2022). ...

The data obtained were subjected to one-way ANOVA to investigate the effect of dietary selenium nanoparticle and selenomethionine on growth performance, hepatic enzymes' activity, and mucosal immune parameters in goldfish Azarin et al. 2020).

... The capacity of probiotics to enhance fish nutrition-related and digestive factors has piqued the interest of a number of studies in recent years, which are investigating the impact of probiotics on the reproductive factors of aquaculture species. The research in sea bream Sparus aurata (Ghoname et al. 2020), goldfish Carassius auratus (Mehdinejad et al. 2018), European eel Anguilla anguilla (Vílchez et al. 2015), and Nile tilapia Oreochromis niloticus (Mehrim et al. 2015) showed that the dietary administration of probiotics could improve the reproductive performance of the fish. These studies highlight the potential of probiotic treatments in improving broodstock performance and sustaining aquaculture productivity. ...
... The most frequent microorganisms that are being used as probiotics include several species of bacteria, such as Bacillus, Lactobacillus, Bifidobacterium, Enterococcus, Pediococcus, and Butyricicoccus pullicaecorum strains (Eeckhaut et al., 2016;Li et al., 2018;Mehdinejad et al., 2018;Villagrán-de la Mora et al., 2019). Other non-bacterial (fungal) probiotics have also been explored as feed additives for chickens, including Saccharomyces cerevisiae, Saccharomyces bourlardii, Candida pintolopesii and Aspergillus oryzae Fouad, 2020;Villagrán-de la Mora et al., 2019). ...

To determine HSP70 gene expression in a 25 μL reaction volume, a Roche qPCR thermocycler (Roche light cycler 96 machines, Germany) was used. ...
... One major element that should be adjusted with caution to facilitate the search for MIHs in vitro is the duration of incubation; this factor should be adjusted to accurately and optimally exhibit the efficiency of an MIH. In Persian sturgeon, the in vitro success of oocyte maturation was measured using the fertilization rate, which was revealed to decrease with increasing incubation duration (Azarin et al., 2016). On the other hand, the risk of cytotoxicity associated with increased durations of in vitro incubation in culture medium should be carefully considered. ...
