A minimum dose effect was observed at a volumetric concentration of 2.0 mg/mL of 3 in the food, which significantly deterred the shrimp from feeding ( p = 0.01), while a very highly significant rejection response was obtained when testing 3 at a concentration of 3.0 mg/mL ( p < 0.0001) ( Figure 5 ). 3.
