“…For rainbow trout, a few studies have shown that the supplementation of sodium aluminosilicates and bentonites to aflatoxin-contaminated diets reduces intestinal aflatoxin absorption (Ellis et al 2000, Hassan et al 2010; nevertheless, other studies have shown that the addition of aluminosilicates to aflatoxin-contaminated diets for catfish and rainbow trout did not ameliorate their toxic effect (Lopes et al 2009, Arana et al 2011. Suppadit et al (2006) and Soonngam and Hutacharoen (2007) observed that adding HSCAS or vermiculite to aflatoxin-contaminated diets lessened the negative effects triggered by the mycotoxin in Fixat presentaron una disminución en su consumo de alimento (alrededor de 10-12%) y tasa de crecimiento (alrededor de 4-17%); en contraste, los individuos alimentados con NCD + Novasil Plus mostraron un mayor consumo de alimento (alrededor de 6%) y tasa de crecimiento (alrededor de 8%).…”

“…Para la trucha arcoiris, algunos estudios han mostrado que la suplementación de aluminosilicatos de sodio y bentonitas a dietas contaminadas con aflatoxinas reduce la absorción intestinal de aflatoxinas (Ellis et al 2000, Hassan et al 2010. Por otro lado, otros trabajos han demostrado que la inclusión de aluminosilicatos en L. vannamei and P. monodon, but these improvements were not statistically comparable to the uncontaminated diet.…”

The safety and effectiveness of four aluminosilicate-based products (Novasil Plus, Zeolex Extra, Mycofix Select, and Fixat) were tested for 42 days on juvenile Pacific white shrimp, Litopenaeus vannamei, fed diets containing corn grains that had been previously inoculated with Aspergillus parasiticus and then sterilized. Two control diets, one uncontaminated and another contaminated with the contaminated corn grain, were elaborated to contain a final concentration of 0 and 75 μg kg–1 total aflatoxins. Both diets were formulated to contain 38% crude protein and 8% lipids. Eight more diets were manufactured from the previous two to contain each of the test products at inclusion levels of 2.5 to 5.0 g kg–1, in accordance with the inclusion level recommended by the manufacturer. Mycofix Select and Fixat inclusion improved diet stability (12–16%). Water absorption capacity in the diets increased (from 2% to 17%) due to the supplementation of aluminosilicates. Feeding aflatoxin-contaminated diets to Pacific white shrimp resulted in lower feed intake and weight gain without affecting the feed conversion ratio, nitrogen retention, and survival. Feeding the uncontaminated diets supplemented with Zeolex Extra, Mycofix Select, and Fixat resulted in a slight reduction in feed intake without affecting growth rate, nitrogen retention, or survival. Conversely, the inclusion of Novasil Plus in the uncontaminated diet did not affect feed intake and an 8% growth rate improval was observed. Three of the tested products failed to provide complete restoration of feed consumption and shrimp growth rate when added to the aflatoxin-contaminated diet.

“…Ellis et al [1] have reported that a 2% inclusion level of bentonite (a common clay containing montmorillonite) in trout feed reduced toxic AFB1 effects. Hassan et al [44] in their studies suggest that a 0.5% inclusion level was sufficient to protect tilapia from 1.5 ppm AFB1. In anather study, Bentonites have been added into fish feed at concentrations up to 10% with no alteration in whole-body proximate composition [45].…”

“…Two-percent bentonite clay inclusion has been used in rainbow trout feed to reduce toxicity resulting from 0.02 mg/kg of AFB1 exposure and significantly decreased liver cancer rates (Ellis, Clements, Tibbetts, & Winfree, (2000). Hassan et al (2010) concluded that Egyptian bentonite (EB) and montmorillonite (EM), which have the ability to bind tightly with AFB1 in the gastrointestinal tract of the fish decreases its bioavailability. Moreover, the two tested clays were safe and use as potential aflatoxin binder in animal feed.…”

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.
