(IA) personnel. IA is the company's ecological consultant. The shortnose sturgeon is an endangered species listed under the Endangered Species Act of 1973.

DESIGNATION OF APPARENT CAUSE OF OCCURRENCE:

Based on the prior sighting of a large dead fish in the intake, before the specimen was removed from the trash bars, it is assumed that the specimen was dead prior to-impingement.

Healthy adult and juvenile shortnose sturgeons have cruising swim speeds which range from 8.1 to 34.0 cm/sec and burst swim speeds which range from 30 to 70 cm/sec. Maximum intake velocities through the trash bars are less than these reported cruising speeds. Avoidance of the intake would have been possible by a healthy fish.
