“…The positive correlation between serum TG content and dietary lipid contents suggested that the Yangtze sturgeon showed higher lipase activity and more active endogenous lipid kinetics in response to high‐lipid diets. The results agree well with the findings on other sturgeon species (Guo et al, 2011; Ren et al, 2021). In addition, serum biochemical parameters can intuitively reflect the health and metabolic state of the body.…”

“…Guo et al (2011) reported that the dietary lipid requirement for juvenile hybrid sturgeon (~66.7 g) ( Acipenser baerii ♀ × Acipenser gueldenstaedtii ♂) was estimated to be 11.1% as evaluated by growth performance. The optimal lipid requirements for juvenile Siberian sturgeon ( A. baerii ) (14.19 g) (Ren et al, 2021) and American paddlefish ( Polyodon spathula) (81.38 g) (Liu et al, 2018) were reported to be 169.9–176.0 and 78.8–96.9 g/kg, respectively, suggesting that different sturgeon species had varied lipid requirements. In addition, it has been demonstrated that the nutrient requirements of fish were affected by multiple factors including age/size, feed ingredients, rearing environments, and so on.…”

“…It should be noted that the lipid deposition patterns vary with fish species (Peres & Oliva‐Teles, 1999; Regost et al, 2001; Ren et al, 2018). For sturgeon, the liver and muscle are considered to be the major organs for storing energy where fat and glycogen are prone to be deposited (Ren et al, 2021). Results of the present study indicated that the liver and muscle composition of the Yangtze sturgeon were significantly affected by the dietary lipid, which was reflected by the appreciably influenced lipid content in the dorsal muscle and liver.…”

The supply of a balanced portion of nutrition is vital for the success of the restocking program of the Yangtze sturgeon, an endangered sturgeon in the Yangtze River, however, knowledge of the nutritional requirement of this endangered species is scarce. The present study was performed to investigate the optimum dietary lipid requirement of the Yangtze sturgeon juveniles (initial weight, 184.24 ± 6.79 g). Five isonitrogenous diets containing a mixture of fish oil and soybean oil (1:1 ratio) at five different levels (35, 63, 90, 124 and 168 g/kg) were prepared and each prescribed diet was hand‐fed to triplicate groups of fish for 50 days. Results showed that feed intake of fish was not affected, but growth and feed utilization rate increased and then declined with the increment of dietary lipid content. Similar trends were observed for the activities of enzymes involved in lipid digestion and metabolism. The lipid content of fish dorsal muscle and liver together with serum triglyceride content was linearly elevated with increasing inclusion of dietary lipid. The inclusion of 12.4% dietary lipid significantly reduced the content of deamination product ammonia in serum. Excessive lipid intake caused noticeable hepatocellular vacuolation as shown by histological staining. Based on the regression analysis between growth response and dietary lipid levels, the optimum dietary lipid level of juvenile Yangtze sturgeon was estimated to be 141.67 g/kg diet.

“…Insufficient or excess dietary lipid levels elevated the ALT and AST values in golden pompano [ 72 ]. This showed liver dysfunction in Siberian sturgeon ( Acipenser baerii ) [ 73 ] and hybrid snakehead ( Channa argus× Channa maculata ) [ 74 ]. The 2Stresses group had lower ALT levels than the other treatments, indicating that this group had slightly greater liver health, which is consistent with improved growth and immunological response.…”

Early-life exposure to mild stressors can assist animals in coping with more stressful events in later life. This study was aimed at investigating how early stress and dietary lipid contents affect growth, hematology, blood biochemistry, immunological responses, antioxidant system, liver enzymes, and stress responses of oscar (Astronotus ocellatus) ( 6.8 ± 0.7 g). Six experimental treatments were HL0Stress (high-lipid diet and without stress), HL2Stresses (high-lipid diet and two-week stress), HL4Stresses (high-lipid diet and four-week stress), LL0Stress (low-lipid diet and without stress), LL2Stresses (low-lipid diet and two-week stress), and LL4Stresses (low-lipid diet and four-week stress). During the ten-week trial, fish fed high-lipid diets grew faster ( 46.41 ± 4.67 vs. 38.81 ± 2.81 ) and had a lower feed conversion ratio (2.21 vs. 2.60) than those fed low-lipid diets ( P < 0.05 ). After acute confinement stress (AC stress), high-lipid groups had higher survival than low-lipid treatments (81.25% vs 72.92%) ( P < 0.05 ). Fish subjected to two-time stress (2Stresses) had a higher survival rate after AC stress (90.63% vs. 62.50%), hematocrit, white blood cell, blood performance, total protein, high-density lipoproteins, cholesterol, triglyceride, alternative complement activity (ACH50), superoxide dismutase, glutathione peroxidase, and alkaline phosphatase levels than those not stressed ( P < 0.05 ). Contrariwise, glucose, cortisol, alanine aminotransferase, and aspartate aminotransferase levels were significantly lower in the 2Stresses groups compared with 0Stress fish ( P < 0.05 ). Collectively, these findings suggest stressing the signs of adaptation in 2Stresses fish. However, a higher number of early stress events (4Stresses) appears to exceed the threshold of manageable stress levels for this species. In conclusion, the HL2Stresses group outperformed the other treatments in terms of growth, health status, and stress responsiveness. Although fish welfare must be considered, these results suggest that early mild stress can result in a greater survival rate after fish are exposed to later acute stress.
