In recent years, several factors have caused the price of fish meal to rise, so the trend of replacing fish meal with low-priced vegetable protein raw materials is becoming more and more obvious, which leads to the increasing risk of aquatic feed being polluted by one or more mycotoxins. More crops are polluted by mycotoxins, which is a common problem in animal feed industry.

? The toxic effects of mycotoxins on animals are well known and different. Such as: carcinogen (aflatoxin B 1(AFB 1)), ochratoxin A(OTA), fumonisin B 1, estrogen (zearalenone ZON), nerve (fumonisin B 1), kidney (fumonisin B1)

Although the number of studies on the effects of mycotoxins on aquaculture varieties is limited, studies have shown that mycotoxins can cause various diseases and growth performance problems of different fish and shrimp. Because mycotoxin has a serious impact on fish, it is particularly important to determine the content of mycotoxin in feed.

Through the overall analysis of soybean meal, cassava, rapeseed meal and meat and bone meal, the pollution degree of Aspergillus flavus, DON and OTA is high, with the pollution degree of 22%, 24% and 20% respectively. Among them, Aspergillus flavus contaminated samples accounted for 46% of the total samples, and OTA accounted for 42? %。 Besides, in the flour, don? With ZON? It is a very common mycotoxin, and the contaminated samples account for 63% and 58% of the total samples respectively, with an average content of 75 and 65 1μg/kg respectively.

Studies on fish and shrimp show that mycotoxin has a great influence on it. The analysis data of mycotoxin in aquatic feed shows the importance of mycotoxin problem management strategy. Fish farms must establish a mycotoxin management system to minimize the harm of mycotoxin to the productivity of fish and shrimp.
