Abstract
The outlook for the aquaculture market remains volatile in terms of availability of raw materials, quality of raw materials, prices and production results.
Difficulties in obtaining raw materials have sometimes resulted in the acceptance of raw materials that do not meet or fall below specifications. Issues of climate change, storage, and logistical challenges have led to increased occurrence of mycotoxins in plant raw materials used to produce aquafeeds.
Recent research has shown that contamination with aflatoxins, fumonisins, ochratoxins, zearalenone and trichothecenes is increasing in shrimp feed. The risks of feeding these mycotoxins to shrimp can result in reduced growth, impaired immune functions and increased susceptibility to bacterial and viral infections, with significant economic losses for farmers. The accumulation of mycotoxins in shrimp tissue can affect flesh quality and cause adverse health effects in humans who consume contaminated shrimp.
To mitigate the risks of mycotoxin contamination in shrimp farming, it is important to implement a solid mycotoxin risk management plan in shrimp farming and feed production. Sound measures include the use of mycotoxin deactivator for raw materials quality control, proper storage and handling of feed ingredients, and regular monitoring of mycotoxin levels in feed. The use of mycotoxins deactivator in shrimp feed has shown promising results in reducing the bioavailability of mycotoxins and mitigating their toxic effects on shrimp and humans.
