| brain acetylcholinesterase activity in shiner perch (cymatogaster aggregata) and juvenile chinook salmon (oncorhynchus tshawytscha) after application of carbaryl to control burrowing shrimp within willapa bay, washington. | carbaryl has been applied in willapa bay, washington, for five decades to control burrowing shrimp (neotrypaea californiensis and upogebia pugettensis) on commercial oyster (crassostrea gigas) beds. concerns about effects on nontarget species, including fishes, have led to restrictions in use despite a lack of data on in situ exposure. we measured brain acetylcholinesterase (ache) activity in adult shiner perch (cymatogaster aggregata) and juvenile chinook salmon (oncorhynchus tshawytscha) after ... | 2013 | 24042340 |
