Why weren't trouts affected by the DDT?

Trouts were not significantly affected by DDT due to their position in the aquatic food chain and the specific environmental conditions of their habitats. While DDT was harmful to many organisms, trouts often bioaccumulated lower levels of the pesticide compared to other species higher up in the food chain. Additionally, trouts have certain physiological adaptations that can mitigate the toxic effects of pollutants. However, it's important to note that DDT can still impact their food sources and overall ecosystem health.
