“…Among the biological functions of carotenoids in aquaculture, the antioxidant properties can be closely associated with stress resistance. An enhancement of resistance to dissolved oxygen depletion stress (Niu et al, ), salinity and thermal stress (Chien, Pan, & Hunter, ; Meng et al, ), and pollution and pathological stress (Amar, Kiron, Akutsu, Satoh, & Watanabe, ; Elseady & Zahran, ; Pan, Chien, & Hunter, ) in aquatic organisms was associated with an increase in dietary and body carotenoids. Then, the application of this kind of dietary antioxidant could provide valuable new, secure and efficient rearing techniques for farm aquaculture in the near future.…”

Dietary β‐carotene improves growth performance and antioxidant status of juvenilePiaractus mesopotamicus

This study was conducted to investigate the effects of dietary synthetic β‐carotene on growth performance, haematological and immunological parameters, energy reserves and antioxidant status of juvenile fish Piaractus mesopotamicus. Two hundred and ten fish (12.24 ± 2.98 g) were fed with a control extruded feed (CEF) and the same diet supplemented with β‐carotene (BEF) for 90 days. A higher weight gain and specific growth rate were found in fish fed BEF in comparison with those fed CEF. In addition, BEF‐fed fish showed lower liver somatic index and a higher percentage of eosinophils. No statistical differences were found in energy reserves, except for plasma triglycerides which decreased in fish fed with BEF. Regarding oxidative stress markers, decreased activities of antioxidant enzymes were found in intestine and gills of BEF‐fed fish (SOD and GST, respectively). In the liver, both LPO levels and CAT activity decreased in fish fed with BEF. Additionally, lower brain LPO levels without changes in the antioxidant enzymes were observed in BEF‐fed fish. The inclusion of dietary synthetic β‐carotene improved growth and antioxidant status, and had a plasma triglyceride‐lowering effect in juvenile P. mesopotamicus.

“…Similar results about effect of environmental stress such as low temperature and Vibrio parahaemolyticus on CAR content have been reported in the noble scallop (Han et al, ; Lu et al, ). Meng et al () found the higher SOD level in Pinctada fucata demonstrated the stronger resistance to stress. We also found that the MDA content increased in the scallops after low salinity stress.…”

“…Generally, the MDA content is inversely correlated to the stress resistance. For example, in C. nobilis , MDA level in lesion groups was significantly higher than that in health groups (Lan et al, ), and in P. fucata , the MDA increased with time under thermal stress (30°C), the normal living temperature of P. fucata was about 26°C (Meng et al, ).…”

(quantity of heat), through this process, CAR can capture and quenching singlet oxygen (Edge, Land, McGravey, Mulroy, & Truscott, ; Miyashita, ; Sachindra et al, ). What is more, CAR can regulate the expression of genes related to immune/resistance (Meng et al, ; Pap et al, ), molluscs with high CAR content exhibit high resistance to sea pollution (Karnaukhov, Milovidova, & Kargopolova, ). However, animals cannot synthesize CAR by themselves and must accumulate CAR in their body from their diet.…”

Differential responses to low salinity on gene expression, physiological and biochemical indexes between the golden and brown noble scallopsChlamys nobilis

et al. 2019

Low salinity is one of important environmental factors which often led to mass mortality of the noble scallop Chlamys nobilis cultivated in the South coast of China. It is well known that enzymic system and non‐enzymic system both play crucial roles in all living organisms against severe environments. To investigate how change about enzymic system and non‐enzymic system in the stenohaline marine bivalve under low salinity stress, an acute challenge lasting 48 hr was conducted using golden and brown noble scallops in the present study. The serine proteinase inhibitor from the noble scallop (CnSPI) was first cloned and expressed in different tissues. After low salinity stress, the gene expression levels were determined in haemocytes and compared between golden and brown scallops. Meanwhile, total carotenoids content (TCC) in adductor, superoxide dismutase (SOD) enzymatic activity and methylenedioxyamphetamine (MDA) content in gill and haemocytes were also determined and compared between the two colours scallops. Results showed that the CnSPI gene expression levels were significantly decreased after low salinity stress, and the golden scallops had higher gene expression levels than brown scallops (p < .05) at most times. Moreover, after low salinity stress, TCC, SOD enzymatic activity and MDA content also fluctuated, and the golden scallops contained higher TCC and SOD, but lower MDA than the brown ones. The present results indicated that enzymic system and non‐enzymic system were both changed under low salinity stress in the noble scallop and significantly different responses to the stress existed between golden and brown individuals. The SPI gene and carotenoids (CAR) both play a resistant role to low salinity stress in the noble scallop.

“…However, high mortalities occurred frequently in high temperature (temperature > 28°C) during the summer season. Yet in selectively breeding, we found that carotenoids enriched pearl oysters have higher survival rate and total antioxidant capacity (TAC; Meng et al., 2017). Carotenoids are a group of bioactive natural pigments synthesized by higher plants, algae (especially marine algae), bacteria and fungi, which are obtained by animals via dietary intake (Hempel et al., 2014; Matsuno, 2001; Reyes, Gomez, & Kao, 2014; Takaishi, Satsu, Takayanagi, Mukai, & Shimizu, 2012; Thomas et al., 2014; Vilchez et al, 2011).…”

We characterized a novel stearoyl‐CoA desaturase gene from Pinctada fucata, named PfSCD, and investigated the expression levels in various tissues of high and low carotenoid contents (orange and white groups) and the responses to high temperature stress (from 26°C to 30°C). The complete cDNA sequence consisted of 1,576 bp with a 945 bp open reading frame encoding 315 amino acid residues; it included four transmembrane domains and three conserved histidine‐box motifs. Pinctada fucata was clustered with molluscan SCD genes. The relative expression level of PfSCD mRNA, total carotenoid content (TCC) and total antioxidant capacity (TAC) was greatly up‐regulated in orange group as compared with the white, with the highest in hepatopancreas and followed by gonad tissue and the lowest in foot. The relative expression level of PfSCD increased first and then decreased during the stress period of temperature 30°C from 0 to 96 hr in the orange group with the peaks at 6 and 12 hr. Meanwhile, TCC and TAC decreased gradually during the stress, with a significant increase at 6 hr in the hepatopancreas and gonadal tissues, respectively, in the orange group, corresponding to the rise of PfSCD at 6 hr. It suggested that carotenoids can be up‐regulated by PfSCD. Moreover, the positive correlations of PfSCD mRNA with TCC and TAC were both disrupted under the high temperature stress. These findings suggested that SCD and carotenoids can be up‐regulated by each other and concertedly enhance the resistance of the oyster to high temperature stress.
