Growth performance, haemato‐immunological responses and antioxidant status of Pacific white shrimp Penaeus vannamei fed with turmeric powder, curcumin and curcumin nanomicelles

Abstract

Effects of dietary administration of turmeric (TUR), curcumin (CUR) and curcumin nanomicelles (NMC) were investigated on growth, haemato-immunology and antioxidant status of the Pacific white shrimp Penaeus vannamei. The shrimps (2.96±0.10 g) were fed with 10 diets: without supplementing TUR, CUR and NMC (control), supplemented with 2.5, 5 and 10 g TUR, 0.075, 0.150 and 0.300 g CUR and 0.075, 0.150 and 0.300 g NMC per kg of diet. CUR 0.075 and NMC 0.150 improved final weight, weight gain (%), specific growth rate and feed conversion ratio. Survival rate was more increased with NMC 0.150, which improved the biomass gain. The lowest levels of serum alanine transaminase and aspartate transaminase and the highest levels of acid phosphatase, total antioxidant capacity, glutathione, catalase and superoxide dismutase were detected in NMC 0.150 (p < .05). Malondialdehyde was significantly lower in NMC 0.150 compared with the control. NMC treatments showed higher levels of total protein, lysozyme and albumin than the other treatments. It is concluded that both the dietary CUR and NMC improved the antioxidant and immunity response of P. vannamei, however, NMC 0.150 induced a better overall shrimp performance.Application of nanocarriers for the delivery of dietary immunostimulants seems promising in shrimp nutrition.

Dietary turmeric, curcumin and nanoencapsulated curcumin can differently fight against salinity stress in Pacific white shrimp Penaeus vannamei Boone, 1931

“…on the growth and haemato-immunology of P. vannamei have been previously reported (Moghadam et al, 2021). Those findings documented that the growth and immunity response of P. vannamei was improved by CUR and NMC supplementation to the diet.…”

“…The effects of dietary administration of different forms of CUR on the growth and haemato‐immunology of P . vannamei have been previously reported (Moghadam et al, 2021). Those findings documented that the growth and immunity response of P .…”

“…All the tanks contained filtered seawater with constant aeration supplied with an air stone linked to a central air compressor. Photoperiod was kept on a 14:10 (light: dark) cycle (Minabi et al, 2020; Moghadam et al, 2021). Throughout the experiment time, the mean salinity, temperature, pH and dissolved oxygen of the culture water were 37.0 ± 0.4 g L −1 , 32.0 ± 0.5°C, 7.9 ± 0.2 and 6.8 ± 0.3 mg L −1 respectively.…”

“…Therefore, the selection of dosages was based on the TUR analysis and promising results reported in previous studies with CUR and nano‐CUR in P . vannamei (García‐Pérez et al, 2020; Moghadam et al, 2021). TEM image of NMC (9.3 ± 0.2 nm) is shown in Figure 1.…”

“…An electric oven was used to steam the pellets at 80°C for 45 min. The pellets were then air‐dried to about 10% moisture and kept at −20°C (Moghadam et al, 2021). The final weight of the shrimps in the control and experimental treatments after 63 days of culture and before the salinity stress is presented in Figure 2.…”
