“…Zeng et al () reported that 16.9 µg/kg AFB1 was detected in the control shrimp diet without supplemental AFB1. Several other publications also reported that aflatoxin was detected in aquatic control diet (Boonyaratpalin et al, ; Han et al, ; Huang et al, ; Rajeev Raghavan et al, ).…”

A research was accomplished to find the response of Litopenaeus vannamei to different levels of aflatoxin in feed. Two hundred live L. vannamei were collected from a shrimp breeding station located on the south of Tiab, in Hormozgan province. Aflatoxin contaminated diets with 0.18, 96.21, 184.74, 711.35, 977.11 and 1605.61 µg/kg were prepared and shrimps in six experimental groups with three replicates in each group for 28 days were fed with these diets. The results showed that activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT) in haemolymph and histological alternation index (HAI) value of hepatopancreas in treatement groups were significantly higher than control group (p < 0.05). Decreased total protein and fat in haemolymph and increased protein in muscle of treatment shrimps were observed compared with the control group (p < 0.05). The HAI value of 977.11 and 1605.61 μg/kg groups were significantly higher than the control and other groups (p < 0.05). Histological study results showed that calculated HAI (more than 100) in these groups as a result of necrosis lesion observed in hepatopancreas. Moderate to severe alteration was recognized in group fed by 711.35 µg/kg aflatoxin. Minor aflatoxin levels (0.18, 96.21 and 184.74 µg/kg) caused inappreciable tissue alteration. This study demonstrated body composition, haemolymph parameters and histology of hepatopancreas were affected in the aflatoxin‐contaminated feed when the concentration was over 955.14 µg/kg.

“…Nevertheless, this indicates that cobia have a relatively high fecundity compared to other asynchronous spawners, which would be a desirable characteristic for their aquaculture. For example, gibel carp Carassius auratus gibelio and tilapia Oreochromis niloticus , as some of the most commonly farmed fish throughout the world, are asynchronous spawners that reportedly have much lower RF values of 2.3–3.5 and 90, respectively (Huang et al., ; Trong, van Arendonk, & Komen, ).…”

Gonad maturation and spawning of cobia, Rachycentron canadum (Linnaeus, 1766) off the Dungun coast, Malaysia

et al. 2018

Summary The reproductive biology of cobia, Rachycentron canadum, from the coastal waters of Dungun, Malaysia was studied from June 2014 to May 2015. From commercial trawls, a total of 201 samples (combined sexes) were collected (fork lengths [FL] 37.5–124.0 cm; body weights 0.5–20.4 g). The overall sex ratio of females to males was 1:0.9, which was not significantly different (χ2 = 2.12, df = 1; p < .05). Estimations of length at 50% maturity (L50) showed that both sexes matured at approximately 75 cm FL; estimated spawning frequency was 6 days. Mean batch fecundity (BF) ranged from 0.55 to 4.32 million eggs. The average number of eggs per gram of ovary was from 2,100 to 5,400 eggs, and relative fecundity 147 eggs/g. There was a weak positive correlation (r2 = .48) between BF and female FL as well as BF with an ovary‐free body weight (r2 = .56), possibly due to females being in a continuous spawning condition and some possibly half‐spent, based on the histological examination of the female gonads. Despite cobia being asynchronous spawners, the gonadosomatic index in both males and females showed peaks in June, November, and particularly March. Based on histological examination, spawning‐capable males were encountered throughout the study period, whereas spawning‐capable females in the late developing subphase were found mostly in March and April. This is the first study on the reproductive aspects of cobia in Malaysian waters.

“…The glutathione conjugates of AFB1‐epoxides are water‐soluble aflatoxin mercapturic acids (AFB1‐NAC), making them more soluble and easier to be excreted from the cells (Egner, Groopman, Wang, Kensler, & Friesen, ). Exposure to AFB1 causes poor growth, immunosuppression, behavioral abnormalities, low apparent digestibility, histological changes, reproduction impairment as well as traces of AFB1 accumulation in the liver and other tissues in gibel carp Carassius auratus gibelio , white shrimp Litopenaeus vannamei , tilapia Oreochromis niloticus and P. monodon (Y. Huang et al, ; Hussain, Mateen, & Gatlin, ; Wang et al, ; Zeng et al, ). Recently, more researchers are focused on the oxidative damage induced by a diet contaminated with AFB1 in aquatic animals including silver catfish Rhamdia quelen and grass carp Ctenopharyngodon idella (Souza et al, ; Zeng et al, ).…”

Identification and expression profile of Delta‐GST in black tiger shrimp (Penaeus monodon) exposed to aflatoxin B1 (AFB1)

et al. 2019

View full text Add to dashboard Cite

Delta GST is an insect‐specific class and a prominent class of the glutathione S‐transferases family that is involved in xenobiotic detoxification and antioxidant defense. The full‐length complementary DNA of delta‐class GST from Penaeus monodon (PmDeltaGST; 839 bp long with a 657 bp coding region) was cloned. The encoded polypeptide of 218 amino acids had a predicted molecular mass of 24.30 kDa. Sequence homology and phylogenetic analysis showed that PmDeltaGST was significant similarity to GST genes in crustaceans and insects. Tissue expression profile analysis by quantitative real‐time reverse‐transcription polymerase chain showed that PmDeltaGST was constitutively expressed in all the examined tissues, with the highest expression in hepatopancreas and intestine and the weakest expression in ovary. PmDeltaGST messenger RNA expression and protein levels in hepatopancreas was significantly increased at 14 days postexposure of aflatoxin B1 (AFB1), keeping on the high level at 28 days, but decreased at 56 days. The results suggested that PmDeltaGST was involved in the response to AFB1 exposure.
