Abstract
Juvenile (5.5–5.7 g) white leg shrimp were exposed to mycotoxin in one indoor trial by feeding fumonisin B1 (FB1) at levels from 0.2 to 2.0 μg g−1 FB1 for 30 days. Shrimp growth was affected after exposure to more than 0.6 μg g−1 FB1. Soluble muscle protein concentration decreased, and changes in myosin thermodynamic properties were observed in shrimp after 30 days of exposure to FB1. Marked histological changes in tissue of shrimp fed a diet containing FB1 at 2.0 μg g−1 were also observed. Shrimp fed diets containing more than 0.6 μg g−1 FB1 showed greater decrease in shear forces after 12 days of ice storage.
