“…Different carnivorous species have various preferences/abilities to utilise lipids. For example, the optimum dietary lipid content in blunt snout bream ( Megalobrama amblycephala ) [ 34 ], tropical gar ( Atractosteus tropicus ) [ 35 ], and orange-spotted grouper ( Epinephelus coioides ) [ 36 ] was 100 g/kg diet, and that in golden pompano ( Trachinotus ovatus ) was 120 g/kg [ 37 ]. However, the optimum dietary lipid levels in salmonids diets were 230 g/kg for rainbow trout [ 38 ], 240 g/kg for Coho Salmon ( Oncorhynchus kisutch ) [ 39 ], 260 g/kg for triploid brown trout ( Salmo trutta ) [ 40 ], 231 g/kg for Chinook salmon ( Oncorhynchus tshawytscha ) (Ridley Corporation) [ 41 , 42 ], and 280 g/kg for Atlantic salmon [ 43 ].…”

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.

“…We speculate that there are significant differences in the nutritional requirements of Chinese sturgeon at different ages. Nutritional composition and ratio of diets play important roles in fish growth [28][29][30]. As the scale of artificial conservation of Chinese sturgeon continues to expand, quantity and quality of natural feed cannot be guaranteed, and an artificially formulated diet must be used.…”

As an endangered animal species, the Chinese sturgeon (Acipenser sinensis) has been artificially cultured during recent years. In the present experiment, the performance of a common formulated feed and a mixed natural feed on the growth and blood physiology of Chinese sturgeon were compared during one year of indoor culture. In terms of specific growth rate, the formulated diet group showed a higher value (4.2%) compared with the natural food group (−1.8%) during one year of indoor culture. Alanine aminotransferase activities of the sturgeons in formulated diet group was significantly higher than that in the natural food group throughout whole experiment period (p < 0.05). The total protein albumin, albumin and globulin contents of the natural food group were significantly higher than that of the formulated diet group in February and May (p < 0.05). The C-reactive protein contents of the formulated diet group were significantly higher than that of natural food group in May and August (p < 0.05). The activities of total cholesterol, high-density cholesterol, and low-density cholesterol were significantly higher in the natural food group than those in the formulated diet group (p < 0.05). The activities of triglycerides were significantly higher in the natural food group than those in the formulated diet group in February and May (p < 0.05). Almost half of the biochemical indicators examined show significant seasonal fluctuations, indicating that seasons have a substantial impact on the Chinese sturgeon. Overall, these results indicate that natural food exerted a positive impact on physiological indicators compared to the formulated diet.
