Description:

Restoration efforts on anadromous fish species have primarily focused on upstream movement of adult fish rather than downstream emigration of their progeny. Low flow conditions, resulting from water withdraws and decreased discharge, can lower dissolved oxygen (DO) levels and impede out-migration of juvenile fish. The present study examined the effects of environmental conditions, including low DO levels, on survival, growth, and out-migration of juvenile American shad. During the spring of 2004, 250,000, hatchery-reared, OTC marked American shad fry were released at locations, separated by passage impediments, in the Exeter River, NH.
