| plasma cholinesterase activity as a biomarker for quantifying exposure of green sturgeon to carbaryl following applications to control burrowing shrimp in washington state. | willapa bay (washington state, usa) has been 1 of the rare intertidal locations where large-scale pesticide applications occur. until recently, carbaryl was applied to control burrowing shrimp that decrease commercial oyster productivity. the bay is a critical habitat for green sturgeon (acipenser medirostris), an anadromous species listed as threatened under the us endangered species act. however, the hazard that carbaryl poses is unknown. surrogate seawater-acclimated white sturgeon (a. transm ... | 2016 | 26678014 |
| assessing the risk to green sturgeon from application of imidacloprid to control burrowing shrimp in willapa bay, washington--part ii: controlled exposure studies. | the activities of 2 species of burrowing shrimp have a negative impact on the growth and survival of oysters reared on intertidal mudflats in willapa bay and grays harbor, washington (usa). to maintain viable harvests, oyster growers proposed the application of the neonicotinoid insecticide imidacloprid onto harvested beds for the control of burrowing shrimp. in test applications, water column concentrations of imidacloprid were relatively low and dissipated rapidly. the foraging activities of t ... | 2015 | 26351255 |
| assessing the risk to green sturgeon from application of imidacloprid to control burrowing shrimp in willapa bay, washington-part i: exposure characterization. | willapa bay and grays harbor (wa, usa) comprise the largest region of commercial oyster cultivation on the pacific coast. the activities of 2 species of burrowing shrimp impair growth and survival of oysters reared on the intertidal mudflats. to maintain viable harvests, the oyster growers have proposed controlling the shrimp by applying the insecticide imidacloprid onto harvested beds. green sturgeon (listed in the endangered species act) forage on burrowing shrimp and could be exposed to imida ... | 2015 | 26031486 |
