Stephen D McCormick
Steve McCormick is a Scientist Emeritus at the Conte Anadromous Fish Research Laboratory in Turners Falls, MA.
Steve’s work has centered on the environmental and hormonal control of water and salt balance, development, growth and reproduction of anadromous fishes, including salmon, trout, shad, alewife, sturgeon and lamprey. This research has addressed important environmental issues including acidification, impacts of dams, endocrine disruptors and climate change, especially the impacts of temperature and salinity. The results of this work have been published in more than 190 papers and book chapters. Steve has been Chair of the Division of Comparative Endocrinology and member of the Executive Board of the Society of Integrative and Comparative Biology, and President and Current Member of the Executive Committee of the Physiology Section of the American Fisheries Society (AFS). He has been a visiting scientist at the University of Goteborg (1988) and Ocean Research Institute of the University of Tokyo (1990), James Chair Visiting Professor at St. Francis Xavier University, Nova Scotia, Canada (1999) and Visiting Scholar at Hokkaido University, Sapporo, Japan (2002). In 2014 he received the Excellence in Fish Physiology Award for lifetime achievement from the Physiology Section of AFS. He has been an adjunct Professor of Biology at the University of Massachusetts, Amherst since 1990 and Associate Editor of General and Comparative Endocrinology since 1996.

The loss of hyperosmoregulatory ability in migrating juvenile American shad, Alosa sapidissima
Investigations on juvenile American shad (Alosa sapidissima) revealed several physiological changes associated with downstream migration. Plasma chloride decreased 20% in wild juvenile shad during the autumn migration. Migrants had lower condition factor and hematocrit than non-migrant shad captured by beach seining. Gill Na + ,K + -ATPase activity of migrant shad was higher than non-migrant; a 2.

Effects of growth hormone and insulin-like growth factor I on salinity tolerance and gill Na+, K+ and -ATPase in Atlantic salmon (Salmo salar): Interaction with cortisol
The potential roles of growth hormone (GH) and insulin-like growth factor I (IGF-I) in seawater (SW) acclimation of juvenile Atlantic salmon (Salmo salar) were examined. Compared to controls, fish in 12 ppt seawater given one or three injections (2–6 days) of GH (ovine, 0.2μg · g−1) or IGF-I (recombinant bovine, 0.05–0.2μg · g−1) had significantly greater salinity tolerance as judged by lower plas

Increased daylength stimulates plasma growth hormone and gill Na+, K+ and -ATPase Atlantic salmon (Salmo salar )
Atlantic salmon juveniles reared at constant temperature (9–10°C) were exposed to four photoperiod treatment and sampled every 2 weeks from January through May. Fish reared under normal photoperiod exhibited eight-and three fold increases in plasma growth hormone and gill Na+, K+-ATPase activity, respectively, between January and April. Fish exposed to abrupt increases in daylength (LD 15:9) in Fe

Circulating growth hormone, cortisol and thyroxine levels after 24 h seawater challenge of yearling coho salmon at different developmental stages
The response of the endocrine system to short-term exposure to sea water (SW) was examined before, during and after the parr-smolt transformation of coho salmon. Five transfers of yearling coho salmon (Oncorhynchus kisutch) from fresh water (FW) to FW, or from FW to SW for 24 h were carried out between March and September. Condition factor declined significantly in late April, and gill Na+, K+-ATP
