Optimization of Culture Temperatures for Larval Pacific Lamprey

摘要

The Pacific lamprey Entosphenus tridentatus is one of the oldest native fish in the Pacific Northwest, USA. At an estimated 450 million years old, these lampreys have seen many other species come and go from the earth. Despite their ability to persistthrough numerous global mass extinction events, the Pacific lamprey is currently a species of concern in response to reductions in range and declines in abundance that have occurred within the last century due mainly to habitat destruction, dams and other barriers topassage (Close et al. 2002, Moser and Close 2003, Moyle et al. 2009).
