“…Thus, the present study was designed to address this potential limitation of DDGS inclusion in aquafeeds. However, our results do not agree with observations reported by Abdelaziz et al (2010) and Agouz and Anwer (2011), who found substantial increases in fish performance when mycotoxin binder products were included in mycotoxin-contaminated feeds. Possible reasons for these differing results include differences in (1) the types and levels of mycotoxins examined and (2) the mycotoxin deactivators utilized.…”

“…Possible reasons for these differing results include differences in (1) the types and levels of mycotoxins examined and (2) the mycotoxin deactivators utilized. In our study, the mycotoxins present in the HPDDG sample were deoxynivalenol and zearalenone, whereas Abdelaziz et al (2010) and Agouz and Anwer (2011) evaluated fish feed that was contaminated with aflatoxin and ochratoxin. Additionally, the calculated mycotoxin levels based on the 24% HPDDG inclusion level in the current study were 0.6 g/g for deoxynivalenol and 410 ng/g for zearalenone.…”

“…Our results further the work of Øverland et al (2013) by successfully reducing the fish meal level to 13% via HPDDG replacement without compromising growth. Although limited research has investigated the potential importance or confounding effects of low-level mycotoxin contamination in alternative ingredient evaluations, the use of mycotoxin deactivation products in contaminated fish feeds has previously been shown to increase growth performance (Abdelaziz et al 2010;Agouz and Anwer 2011). Thus, the present study was designed to address this potential limitation of DDGS inclusion in aquafeeds.…”

The Effect of a Mycotoxin Deactivation Product on Growth of Juvenile Rainbow Trout Fed Distillers Dried Grains

Distillers dried grains (DDG) with solubles (DDGS) is a product that has shown potential as a protein source for some fish species, but high inclusion rates of DDGS have not always been successfully achieved for Rainbow Trout Oncorhynchus mykiss. Our objective was to determine whether inclusion of a mycotoxin deactivation product (Biofix Plus) could improve the ability of high‐protein DDG (HPDDG) to replace a portion of the fish meal in diets for Rainbow Trout. The 2 × 2 factorial feeding trial examined protein source (menhaden fish meal [MFM] or HPDDG) with or without Biofix Plus. A control diet (42% digestible protein, 20% crude lipid, 25% MFM) was compared to a test diet in which HPDDG replaced 12% of the total MFM on a digestible‐protein basis (24% HPDDG inclusion). Diets were fed to juvenile Rainbow Trout (initial weight: mean ± SE = 30.5 ± 1.6 g) in four replicate tanks per treatment for 9 weeks in a 15°C recirculating system. At the conclusion of the feeding trial, we observed no negative effects of fish meal replacement on growth or feed conversion ratio; no benefit of Biofix Plus supplementation was observed. These data indicate that when Rainbow Trout diets containing a high‐quality DDGS product are balanced for digestible protein, lysine, methionine, and threonine, dietary fish meal levels can be successfully reduced to 13% without compromising growth and without the need for mycotoxin deactivator inclusion.

There is increasing awareness of the negative effects of mycotoxins in aquatic species, which is highlighted in recent publications. Partly due to climate change associated with an overall increase of mycotoxins contamination in plant ingredients, and also due to the tendency to replace expensive animal‐derived proteins, such as fish meal, by more economical plant proteins sources, which increases the probability of mycotoxin contamination in aquaculture feeds (Hooft et al. ). Over a 1‐year period, 41 samples of finished aquaculture feed, both shrimp and fish, were analysed within the scope of BIOMIN mycotoxin survey programme. The samples were tested for aflatoxins, zearalenone, deoxynivalenol, fumonisins and ochratoxin A. Samples were sourced in Asia (31 samples) and Europe (10 samples) from fish/shrimp farms or feed producers. The values detected pose a risk for several important aquaculture species, assuming single mycotoxin contamination, that is excluding possible additive and synergetic effects between mycotoxins. Co‐occurrence of mycotoxins in feeds may induce synergistic effects and increase the negative impact of mycotoxins in aquatic‐farmed species at lower levels than when present in single contamination. This review gives an overview of the different mycotoxins and revises the effects of mycotoxins in aquatic species. Additionally, it reports the levels of mycotoxins in aquafeeds in 2014 and compares detected levels with possible negative effects in fish and shrimp. As it is highlighted by the results of the survey, the risk of co‐occurrence is high and the knowledge on the effects of multimycotoxins contamination in aquatic species is basically none.
