Neonicotinoid Insecticide Found to Impact Coastal Aquaculture

Researchers at Australia’s Southern Cross University demonstrated that the neonicotinoid insecticide imidacloprid can impact the feeding behavior of prawns in a laboratory environment, leading to nutritional deficiency and reduced flesh quality. Earlier work with shrimp showed similar risks from neonicotinoid exposure, which is a particular concern given increased detection of the water-soluble pesticide in coastal waters worldwide. “This means prawns and shrimp are highly vulnerable if they become exposed to high levels of neonicotinoids, either through contaminated water or feed, which often contains plant-based material,” noted the study’s co-author, adding, “Our research identifies the need for effective management of pesticide use and run-off from intensive agriculture in coastal areas with productive seafood industries.”
