“…This finding supported previous observations on rice field eel (Hu et al, 2018), meagre (de Moura et al, 2018), and yellowfin seabream (Dehghani et al, 2020). Furthermore, the feed intake was promoted by the dietary taurine addition in this and the previous studies with the same fish species (Zhou et al, 2015), indicating that enhanced feed palatability increases growth, also observed in red sea bream (Takagi et al, 2011), rice field eel (Hu et al, 2018) and golden pompano (Ma et al, 2021). Although the CF did not vary with dietary taurine, there was a marginal increase in 10 and 20 g/kg taurine groups vs taurine‐free groups.…”

“…Interestingly, the whole‐body protein level was promoted when groupers fed a 150 g/kg lipid diet with taurine addition. This indicated that exogenous taurine supply could help promote protein utilization in grouper and golden pompano (Ma et al, 2021), and reduce whole‐body lipid deposit in rice field eel (Hu et al, 2018). Previous studies showed that dietary taurine addition could reduce body lipid deposition and promote growth through improving lipid metabolism (Salze & Davis, 2015; Shen et al, 2019; Xu et al, 2020).…”

“…The natural food item is within the range of the taurine level requirement of T. carolinus, but is lower than the taurine requirement of T. blochii. Trachinotus ovatus with an initial body weight of 81 g (Ma et al, 2021) and 14.3 g (Wu et al, 2015) has a taurine requirement of 1 g taurine 100 g −1 and 0.5 g taurine 100 g −1 respectively. The body weight increased in response to an increase in taurine level in the diet.…”

Teolost species, both in juvenile and larval stages, require taurine as an essential amino acid (Salze & Allen Davis, 2015). Physiological and metabolic functions in fish, such as anti-oxidation process, immunomodulation, growth and osmoregulation, necessitate taurine (Salze et al., 2018). Taurine is abundant in live or natural food used in the seed production of aquatic species and is considered a conditionally essential nutrient in feed for various cultured species (Takeuchi, 2014).Dietary taurine supplementation is necessary while replacing the fish meal with plant-based proteins in the diet (Gaylord et al., 2007;Lunger et al., 2007). For example, 0.2% taurine in a formulated diet containing 25% soy protein concentrate improved the growth of common dentex, Dentex dentex weighing 39 g (Chatzifotis et al., 2008). Moreover, Japanese flounder, Paralichthys olivaceus, weighing 0.9 g required 1.4% taurine in diets for optimum growth (Park et al., 2002). Similarly, white seabass, Atractoscion nobilis, weighing 0.4 g required 0.99% dietary taurine (Jirsa et al., 2014), while the yellowtail, Seriola lalandi, weighing 470 g necessitated taurine for normal growth performance and physiological condition when fed a diet consisting of soy protein concentrate (Takagi et al., 2008).When the diet is deficient in taurine, poor growth, reduced survival, presence of physiological abnormalities and high mortality linked to compromised immune system of the fish have been observed (Salze & Allen Davis, 2015). Albeit the effects of taurine and

Streptococcus agalactiae is common pathogenic bacteria in aquaculture and can cause mass mortality after fish infection. This study aimed to investigate the effects of S. agalactiae infection on the immune and antioxidant regulatory mechanisms of golden pompano (Trachinotus ovatus). Serum and liver samples were obtained at 0, 6, 12, 24, 48, 96, and 120 h after golden pompano infection with S. agalactiae for enzyme activity and gene expression analyses. After infection with S. agalactiae, the content of reactive oxygen species (ROS) in serum was significantly increased (p < 0.05). Serum levels of glucose (GLU), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and malondialdehyde (MDA) increased and then decreased (p < 0.05), reaching a maximum at 6 h. Serum antioxidant enzyme (LZM) activity increased significantly (p < 0.05) and reached a maximum at 120 h. In addition, the mRNA expression levels of antioxidant genes (SOD, CAT, and GPx) in the liver increased and then decreased, reaching the maximum at 24 h, 48 h, and 24 h, respectively. During the experimental period, the mRNA expression levels of NF-κB-related genes of the inflammatory signaling pathway inhibitory κB (IκB) showed an overall decreasing trend (p < 0.05) and the lowest expression at 120 h, whereas the mRNA expression levels of tumor necrosis factor α (TNF-α), interleukin-1β (IL-1β), IκB kinase (IKK), and nuclear factor NF-κB increased significantly (p < 0.05) and the highest expression was at 120 h. In conclusion, these results showed that S. agalactiae could activate internal regulatory signaling in the liver of golden pompano to induce defense and immune responses. This study is expected to lay a foundation to develop the healthy aquaculture of golden pompano and promote a more comprehensive understanding of its disease resistance mechanisms.
