“…Finally, Hussain et al . () showed a high deposition of AF in tilapia muscle, however, the levels of mycotoxins used in this trial (2,000–4,000 μg kg −1 ) are unlikely to be found in aquafeeds although TFs calculated for AF deposition in the liver are in line with the other studies. The only trial with red tilapia ( O. niloticus × O. mossambicus ), (Usanno et al .…”

“…Tropical species have been particularly studied covering both Asian and South American species. Regarding Nile tilapia (O. niloticus) eight studies have been published to date (Salem et al 2009;Deng et al 2010;Ayyat et al 2013;Hessein et al 2014;Selim et al 2014;Mahfouz & Sherif 2015;Abdel Rahman et al 2017;Hussain et al 2017). All studies detected bioaccumulation of AF in muscle and the liver (Table 2).…”

Mycotoxins, secondary metabolites produced by moulds, are responsible for causing significant economic losses due to spoilage of agricultural products but also due to direct or indirect health impact on livestock upon ingestion of mycotoxin contaminated feedstuffs. Aquaculture farmed species are not an exception and studies reporting mycotoxin‐related issues in the aquaculture industry have been increasing. However, our understanding on the prevalence and impact of mycotoxins in the aquaculture sector is still lower compared to the terrestrial livestock sector. Consequently, regulatory limits and guidance values have been defined based on the studies on terrestrial farm animals. The aim of this review is to compile and critically assess mycotoxin occurrence and co‐occurrence in aquaculture finished feeds, and understand the risk of mycotoxin carry‐over in aquaculture seafood products. Furthermore, we aim with this review to raise awareness to the scientific community, the regulatory authorities and the aquaculture industry to the need for specific aquaculture mycotoxin maximum concentration levels for both aquaculture feeds and foods.

“…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)

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.

“…Bentonites, zeolites and activated carbon are the most studied aflatoxin adsorbents. Hussain et al (2017) conducted an experiment to evaluate the efficacy of 4TX bentonite clay at 0.5 and 10% levels against 2 and 4 mg/kg AFB1 induced toxicity in Nile tilapia along with control. The inclusion method of the clay in the remaining diet ingredients was also compared.…”

Aflatoxins are among all known mycotoxins, the most widespread source of contamination of food and feed throughout the world. In aquaculture and aqua-feed formulations the increased use of plant based materials has intensified the risks of aflatoxicosis in farmed fish because of the high load of aflatoxin by the vegetable sources. The aflatoxins production by toxic fungal strains can take place in the field directly, during different processing stages like insiling, aqua feed formulation, preparation and due to improper feed storage. However, the thermal treatments can only destroy the fungus but have no effect on the heat-resistant mycotoxins present in mycelium and spores of the mold. So, the aflatoxin accumulation in fish meal and fish feed represents a great threat for the aqua-cultured species and ultimately for the consumer's health and safety. Consequently, the issue of aflatoxin contamination in fish and aquaculture industry has intensified. This review focused on the deleterious effects of aflatoxins in fish and aquaculture and the possible remedy by the use of adsorbents.
