“…By contrast, once the liver cells are damaged, the cytoplasmic AST/ALT is released from the hepatocyte into the blood, resulting in elevated concentrations (Kim et al, 2008). It should be pointed out that the liver is an indicative organ to evaluate the nutritional and physiological status of fish, and imbalanced nutrition intake can cause disorders of liver function and clinical changes in histological status (Peng et al, 2022). In the present study, both AST and ALT activities in serum were relatively stable with the enhancement of dietary lipid, denoting that if not beneficial, this amount of lipid in this present study is probably not detrimental to juvenile Yangtze sturgeon (Liu et al, 2021).…”

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.

“…Previous studies of potential correlations between light and fish behaviors have mainly focused on phototaxis [ 10 , 11 ], changes to circadian rhythms [ 12 ], and growth and development [ 13 , 14 , 15 ]. Recent studies of S. chuatsi have mainly focused on selective breeding [ 16 ], breeding technologies [ 17 ], feed formulations [ 18 ], nutritional quality [ 19 ], and disease susceptibility [ 20 ]. A few studies have investigated the re-feeding behaviors and morphological changes of S. chuatsi after starvation, such as Lu et al [ 21 ] for growth hormone receptors, Chen et al [ 22 ] for insulin-like growth factor 1 receptors, Zhu et al [ 23 ] for microRNA profiles, Wang et al [ 24 ] for gene expression profiles, and Shi et al [ 25 ] for memory function.…”

Light influences the stress response to environmental stimuli and feeding behaviors of Siniperca chuatsi and, thus, is an important regulator of normal growth and development. In this study, we first explored the important role of light on the digestive and stress capacity of S. chuatsi by studying the changes in physiological and biochemical indicators of S. chuatsi, taking the re-feeding after starvation as the constant environmental stimulus and the light intensity as the adjustable environmental stimulus. The activity of protease and lipase was generally higher in the stomach tissues than in the intestinal tissues, especially lipase, which was higher in stomach tissues under all light conditions, and the protease and lipase activity peaked in the stomach tissues of S. chuatsi at a light intensity of 18.44 ± 3.00 lx and in intestinal tissues at 11.15 ± 2.01 lx, respectively, indicating that greater light intensity increased the digestive capacity of stomach tissues, whereas lower light intensity facilitated the digestive capacity of intestinal tissues. The tissues of the gill, stomach, and intestine had relatively high activity of stress-related enzymes, whereas the tissues of the brain, kidney, liver, and plasma samples had relatively low activity of enzymes. Collectively, the results show that light intensity at 11.15 ± 2.01 lx promoted digestive capacity in the intestine and enhanced the anti-stress ability of S. chuatsi in response to stress induced by re-feeding after starvation. These findings should prove useful for artificial breeding of S. chuatsi.

Brewer's-spent-yeast (BSY) is among the most voluminous byproducts generated in brewery industry that adds to the waste; however, smart utilization of BSY could lead to edible biomass production besides waste management. To utilize it for biomass production, it is being used in sh feeds; however, its effect on the sh physiology has been scantily studied. The present study investigated the proteomic changes in muscle tissues of carp Labeo rohita fed with BSY-based diet, to understand its impact on muscle physiology and biomass. Six feeds were prepared with different grades of BSY (0, 20, 30, 40, 50, 100% replacement of shmeal with BSY) and shes were fed for 90 days.Highest weight gain%, feed conversion e ciency, speci c growth rate% were observed in 30% BSY-replaced group and this group was considered for the proteomic study. Comparative shotgun proteomic analysis was carried out by LC-MS/MS and data generated have been deposited in ProteomeXchange Consortium with dataset identi er PXD020093. A total of 62 proteins showed differential abundance; 29 increased and 33 decreased in the 30%BSY replaced group. Pathway analysis using IPA and Panther tools revealed that the proteins tyrosine protein kinase, PDGFα, PKRCB and Collagen promote muscle growth by inducing the PI3K-AKT pathway. Conversely, the proteins Serine/threonine-protein phosphatase, Phosphatidylinositol 3,4,5-trisphosphate5-phosphatase 2A, Ras-speci c guanine-nucleotide-releasing factor inhibit muscle growth indicating that 30% BSY replaced feed promote muscle growth in a highly controlled manner. Findings suggest that BSY could be recycled for carp feed production in largescale thereby leading to resource conservation, reducing environmental effects.
