Abstract

Incorporating essential oils as dietary supplements in aquaculture is increasing in popularity. In prawn farming, their use is associated with reduced disease outbreaks, enhanced immunity, and improved animal growth and welfare. Herein, we explored the use of lemon beebrush essential oil (Aloysia triphylla; EOAT) in the diet of juvenile giant freshwater prawns (Macrobrachium rosenbergii) and its potential impact on growth performance and oxidative status of the hepatopancreas. Four hundred juvenile M. rosenbergii (0.40 ± 0.19 g, similar weights between sexes) were fed diets containing concentrations of EOAT at 0.0% (control), 0.1%, 0.2%, or 0.3% for 50 days. Each experimental group had five replicates, with 20 prawns per experimental unit. Prawn survival remained above 84% for all experimental groups. Prawn weight gain, specific growth rate, feed conversion ratio, and body condition were similar among all experimental groups. Dietary EOAT increased activities of the enzymatic antioxidants, catalase and superoxide dismutase, and varied glutathione S transferase activity in the hepatopancreas of prawns when compared to those fed the control diet. Dietary EOAT did not affect malondialdehyde (lipid peroxidation) levels. While EOAT had no impact on survival and growth of M. rosenbergii, it may modulate the detoxification capacity of the hepatopancreas (i.e., metabolic resistance). Future work should prospect EOAT as part of a nutraceutical blend, especially when combined with known growth enhancers and immune stimulants. Based on our results, dietary inclusion of 0.2% EOAT is the most suitable for juvenile M. rosenbergii farming. [ABSTRACT FROM AUTHOR]

Abstract

This study evaluated the anaesthetic potential of clove basil (Ocimum gratissimum) essential oil (EO-OG) in the post-larvae (PLs) of M. rosenbergii. The PLs were individually transferred to aquariums (500 mL) containing 50, 100, 150, 200, or 300 μL L−1 EO-OG. A sixth group of PLs was exposed to freshwater only, and a seventh group was exposed to the highest concentration of ethanol used to dilute EO-OG. Upon reaching the anaesthesia stage, the PLs were transferred to aquariums (500 mL) with freshwater only to evaluate the recovery time. The shortest sedation times were observed at 200 (15.98 s) and 300 μL L−1 (25.85 s). The shortest anaesthesia time was observed at 200 μL L−1 (22.52 s). The longest recovery time was observed at 100 μL L−1 (1367.10 s); the shortest recovery time was observed at 150 μL L−1 (630.10 s). No mortality or adverse effects were observed in any experimental group. The concentration of 150 μL L−1 resulted in sedation (49.24 s), anaesthesia (80.10 s), and recovery (630.10 s) times within those suggested as adequate for freshwater prawn farming. This research demonstrated the sedative and anaesthetic properties of EO-OG and its potential application in prawn farming. This study recommends using 150 μL L−1 of EO-OG in M. rosenbergii PLs.

Abstract

Mugil liza juveniles (6.69 ± 0.06 g) were subjected to dietary citral (0-control, 0.5, 1.0 and 2.0 mL per kg feed) for 45 days, and its possible effects on zootechnical and metabolic parameters, digestive enzymes, innate immunity, oxidative status and liver damage were evaluated. At the end of the experiment, fish fed 2.0 mL citral per kg feed showed a greater weight gain and protein retention efficiency, as well as enhanced activities of pepsin (stomach) and amylase (intestine) compared with control fish. Citral supplementation decreased liver lipoperoxidation and increased the activities of glutathione peroxidase, glutathione-S-transferase and superoxide dismutase in the gills, liver and brain. The highest level of citral inclusion augmented non-protein thiol content in the brain and gills. Myeloperoxidase activity was lower in fish offered 1.0 and 2.0 mL citral per kg feed. Dietary citral did not influence the plasma levels of aspartate aminotransferase and alanine aminotransferase or the hepatic histology. As it improved growth, the activity of digestive enzymes and general health, dietary citral may be recommended for M. liza at 2.0 mL per kg feed. [ABSTRACT FROM AUTHOR]

Abstract

The present study evaluated different levels of the essential oil of Nectandra grandiflora (EONG) in the diet of juvenile Colossoma macropomum. The juveniles (0.75 ± 0.05 g) were fed four experimental diets with differing levels of EONG (0, 0.5, 0.75, and 1.50 mL/kg). After 20 days, the weight, daily weight gain, specific growth rate, and daily feed consumption per fish were highest for the fish fed 0.5 mL EONG/kg, while after 30 days, only the weight and daily feed consumption per fish for that diet remained highest. The viscerosomatic index was highest for the fish fed 0.5 mL EONG/kg while the hepatosomatic index was higher for the groups that received dietary EONG for 30 days. The juveniles fed 1.5 mL EONG/kg showed a proliferative response of the mucous cells in the gills, but the proliferation of these lysozyme- and immunoglobulin-secreting mucosal cells was higher for the skin of the fish of all EONG levels, compared to that of the control fish. The fish fed 0.5 mL EONG/kg had the greatest height and width of intestinal villi. The two highest levels of dietary EONG supplementation (0.75 and 1.50 mL/kg) reduced the hepatocyte dimensions but did not modify the centrolobular vein area. Dietary supplementation with 0.5 mL EONG/kg improved the growth, gut health, and immune response of juvenile C. macropomum. [ABSTRACT FROM AUTHOR]
