“…Blood GLU provides energy to support various life activities in fish and is susceptible to fluctuations in environmental factors [43]. The normal blood GLU content in fish is 2.78-12.72 mmol/L [44]. The blood GLU concentration in crucian carp in the control group was lower than that in each group after anesthesia.…”

Eugenol is a widely used fishery anesthetic. This study investigated the effects of various concentrations of eugenol on blood physiological and biochemical indexes, and muscle flavor, in crucian carp (Carassius auratus). To determine the appropriate concentration of eugenol anesthetic for use in crucian carp transportation and production operations, we evaluated seven anesthesia groups of 20, 30, 40, 50, 60, 70, and 80 mg/L and one control group (without eugenol) to determine the effects on blood physiological and biochemical indexes, and muscle flavor. The red blood cells and platelets of crucian carp decreased significantly (p < 0.05) with eugenol treatment. With increasing eugenol concentration, the white blood cells and hemoglobin did not change significantly, whereas lactate dehydrogenase, alkaline phosphatase, alanine aminotransferase, and aspartate aminotransferase increased significantly (p < 0.05). The content of phosphorus, magnesium, and sodium increased after anesthesia, whereas the content of potassium decreased with increasing eugenol concentration. After anesthesia, the content of albumin and total protein in the serum decreased with increasing eugenol concentration (p < 0.05); triglyceride first increased and subsequently decreased (p < 0.05); blood glucose content first increased and then decreased (p < 0.05); and no significant difference was observed in total cholesterol content (p > 0.05). No significant difference was observed in muscle glycogen and liver glycogen content after eugenol anesthesia (p > 0.05). The eugenol-based anesthesia test did not indicate major liver histomorphological effects, but the very small number of gill sheet edema cases observed requires further study. Analysis of electronic nose data indicated that eugenol treatment affected the flavor of the fish. The anesthesia concentration of 20–80 mg/L had some effect on the physiology and biochemistry of crucian carp, thus providing a reference for the application of eugenol in crucian carp transportation and experimental research.

“…Also, in blunt snout bream fed between 1 and 6 meals per day, the lowest hepatic CAT and GPX activities were detected in fish fed 3 or 4 meals per day, while the total antioxidant capacity was higher in these groups [22]. Similarly, in juvenile tiger puffer (Takifugu rubripes), fish fed 4 or 6 meals per day exhibited lower antioxidant enzyme activities, namely, SOD, CAT, and GPX activities, than those fed only 2 meals per day or continuous feeding [48].…”

The present study evaluated the effects of feeding frequency (FF) and dietary protein/carbohydrate (P/CH) ratios on intestinal histomorphology, microbiota profile, and digestive and oxidative stress-related enzyme activities of gilthead seabream (Sparus aurata). To this purpose, two practical diets were formulated: one with 50% P and 10% CH (P50/CH10) and other with 40% P and 20% CH (P40/CH20). Triplicate groups of fish with 9.1 ± 0.01 g were fed these diets for 60 days until visual satiation at a FF of 1, 2, or 3 meals per day. Distal intestine histomorphology was not affected by diet composition or FF. However, the pyloric caeca (PC) of fish fed 1 meal per day presented more gut fold height alterations than the other groups, except in fish fed diet P50/CH10 3 meals per day, where no changes was observed. Fish fed diet P40/CH20 3 meals per day also presented higher PC submucosa cellularity than the other groups. Fish fed diet P40/CH20 presented a higher number of operational taxonomic units, microbial richness, and diversity indices than fish fed diet P50/CH10. Amylase was the only measured digestive enzyme affected by the experimental conditions, presenting higher activity in fish fed diet P50/CH10 once per day. Glucose-6-phosphate dehydrogenase activity was lower in fish fed 2 meals per day than only 1. While catalase activity was lower in fish fed 2 than 3 meals per day. Glutathione reductase activity was the only measured parameter affected both by dietary P/CH ratio and FF, being inferior in fish fed once per day the P50/CH10 diet than the P40/CH20 diet and, also in the P50/CH10 diet, to fish fed 1 than those fed 3 meals per day. Overall, no major interactions was observed between dietary P/CH ratio and FF; however, a P40/CH20 diet fed 2 meals per day might be recommended for gilthead seabream juveniles.

“…In addition, few studies have evaluated the influence of feeding frequency on metabolic and hematological parameters, which can be analyzed to understand the effects of feeding frequency on the growth and health of these fish. Studies on other species have shown the effects of different feeding frequencies on the hepatosomatic index (HSI) and blood biochemical parameters (Aderolu et al, 2017;Baloi et al, 2014;Gao et al, 2022;Guo et al, 2018;Wu et al, 2021).…”

The Oscar (Astronotus ocellatus) is an important Amazonian species with high production potential in fish farms and commercial value for aquarists. However, limited information on the feeding characteristics, such as the frequency of daily feeding, is available for this species in captivity. Therefore, the objective of this study was to evaluate the effects of feeding frequency on growth, hematology, blood biochemical parameters, liver histology, and intestinal microbiota parameters of juvenile Oscars. Four treatments were tested, consisting of fish fed at a feeding rate of one (T1), two (T2), three (T3), or four (T4) times daily with 1% of their biomass. There were no significant differences (p > 0.05) between treatments for growth and hematological parameters. T1 showed lower serum albumin values than T2 and T4 (p < 0.05) and higher hepatosomatic index values than T4 (p < 0.05), which was corroborated by the hepatocyte nucleus count. Intestinal microbiota analysis revealed higher taxon richness in T4 than in T1 (p < 0.05). Lower feeding frequencies (T1) positively influenced the deposition of hepatic energy reserves and decreased albumin production, possibly because of lower peptide absorption in the same treatment. Based on these results, feeding frequencies of two (T2), three (T3) and four (T4) times daily were the most suitable for juveniles of this species.
