A 6-week feeding experiment was conducted to evaluate whether dietary supplementation of astaxanthin could mitigate negative effects of high-fat diet on growth performance, antioxidant capacity, anti-inflammation, non-specific immunity and intestinal structure of Trachinotus ovatus. Three isonitrogenous diets were formulated supplementing with or without high-fat or astaxanthin (lipid positive (LP): 130 g/kg lipid, lipid negative (LN): 210 g/kg lipid, lipid negative astaxanthin (LNA): 210 g/kg lipid with 0.5 g/kg astaxanthin). Results showed that the growth performance (weight gain (WG) and specific growth rate (SGR)) of T. ovatus in the LN group were significantly How to cite this article:

“…This species is also considered an interesting candidate for aquaculture because of its fast growth and high flesh quality (Tan et al 2016), as demonstrated by different experimental captivity rearing attempts (e.g. Tutman et al 2004, Tan et al 2016, Liu et al 2019. The recent encouraging results notwithstanding (Liu et al 2020), the main obstacle for the use of T. ovatus in Mediterranean aquaculture is the high cost of growing T. ovatus to market size (Tutman et al 2004).…”

“…The recent encouraging results notwithstanding (Liu et al 2020), the main obstacle for the use of T. ovatus in Mediterranean aquaculture is the high cost of growing T. ovatus to market size (Tutman et al 2004). Additional challenges are slow growth and signs of deformity when cultured outside its optimum temperature (26°C -29°C; Yang et al 2016) or salinity range (15‰-25‰; Liu et al 2019) and infections, mainly caused by Vibrio bacteria (Tan et al 2017).…”

This is the first paper to provide detailed information on the age and growth of Trachinotus ovatus. The size of the 244 individuals collected in the Strait of Messina ranged from 2.7 to 30.4 cm in fork length (LF) and 0.31 to 508.6 g in body mass (M). The relationship between these parameters (M - LF) was investigated and showed a good fit. Age estimation based on vertebrae and otoliths yielded similar results, suggesting a maximum age of five years. However, the precision and accuracy tests, such as percentage of agreement (PA), mean coefficient of variation (ACV) and average percent error (APE) indicated that the otolith readings (97.83% PA, 0.54% ACV and 0.38% APE) were more reliable for age estimation than vertebrae readings (82.17% PA, 5.33% ACV and 3.77% APE). The multi-model inference approach allowed us to compare different non-linear growth models. The von Bertalanffy model (L∞=29.139, k=0.496 and t0=−0.347) fitted the length-at-age data best. This species has a relatively rapid growth and an estimated longevity of five to seven years. This information could be used for management and first stock assessment studies on T. ovatus in the Mediterranean Sea.

“…In teleosts, two different patterns of NKA activities were reported in response to changes in salinity: linear and "U-shaped" relationships. For the "U-shaped" relationship, the lowest activity of the gill enzyme occured when the salinity of the medium was close to or slightly above that of the blood (Liu et al, 2019). Some teleosts species showed upregulation in NKA activity when acclimated to hypoosmotic conditions (Lin et al, 2003;Hu et al, 2017).…”

Golden pompano (Trachinotus ovatus) is a commercially important marine fish and is widely cultured in the coastal area of South China. Salinity is one of the most important environmental factors influencing aquatic organisms. In this study, T. ovatus was subjected to the acute salinity stress treatments using four salinity levels of 0‰, 10‰, 20‰, and 40‰ to investigate its physiological and molecular responses. Our results revealed that serum osmolality, Na + , and Clconcentrations showed a similar decreasing trend after salinity stress at the first 2 h and then increased after 8 h. In particular, the Na + /K + -ATPase alpha 1-isoform (Tonka α1) rapidly responded to changes in salinity levels. In the gills, the expression of Tonka α1 was markedly upregulated at 2 h in all the experimental groups (0‰, 10‰, 20‰, and 40‰). In the kidney, Tonka α1 expression in these experimental groups tended first to increase but then decreased, with its values peaking at 2 h, 4 h, and 8 h, respectively. In the intestine, Tonka α1 responded rapidly to salinity changes and then changed dramatically within 4 h under salinity stress. The Na + /K + -ATPase activity was also affected by the acute salinity stress, and it was higher in the 10‰ and 40‰ groups than in the control group (0 h). Interestingly, Na + /K + -ATPase activity was lowest in the 20‰ group. Our results show the various physiological response of T. ovatus under acute salinity stress and demonstrate that under such conditions, Na + /K + -ATPase is primarily involved in the osmoregulation required to maintain homeostasis in this species. changes in concentrations of sodium (Na + ), chloride (Cl-), potassium (K + ), and serum osmolality (Shui et al., 2018). Salinity changes also has a direct influence on hematological and biochemical variables, such as growth hormone, cortisol and thyroxine, which provides essential information regarding clinical status and energy of fish (Arnason et al., 2013).Osmoregulation is the main process by which aquatic animals respond to changes in salinity, especially in fish . Osmolality increases with increased salinity during the adaptation (Schmitz et al., 2017). Euryhaline teleost fishes regulate and maintain their plasma ionic composition and osmotic concentration following changes in the environmental salinity (Yamaguchi et al., 2018). In a hypotonic environment, to maintain ionic homeostasis, teleosts absorb ions through the gills and intestine and excrete excess water, and filter solute to form diluted urine through renal reabsorption. In contrast, in hypertonic environments, teleosts passively lose water and gain excess ions. Therefore, teleosts actively secrete ions and drinking water to maintain homeostasis (Urbina et al., 2013). However, the acclimation to changing environmental salinity is a complex process involved a set of physiological and molecular responses based on the function of several osmoregulatory organs (e.g., gills, kidney and intestine), such as active ion transport of concentration gradients using various molecular ...
