Abamectin effects on aquatic organisms

Abamectin is awful baneful to angle and acutely baneful to amphibian invertebrates. Its LC50 (96-hour) is 0.003 mg/L in bubble trout, 0.0096 mg/L in bluegill sunfish, 0.015 mg/L in sheepshead minnows, 0.024 mg/L in approach catfish, and 0.042 mg/L in carp. Its 48-hour LC50 in Daphnia magna, a baby freshwater crustacean, is 0.003 mg/L. The 96-hour LC50 for abamectin is 0.0016 mg/L in blush shrimp, 430 mg/L in eastern oysters, and 153 mg/L in dejected crab.

While awful baneful to amphibian organisms, absolute concentrations of abamectin in apparent amnion adjoining to advised areas are accepted to be low. Abamectin did not bioaccumulate in bluegill sunfish apparent to 0.099 ug/L for 28 canicule in a flow-through tank. The levels in angle were from 52 to 69 times the ambient baptize concentration, advertence that abamectin does not accrue or abide in fish.
