Autor: Jean V. Adams, Ellie M. Koon, Jenna M. Tews, Kevin A. Mann, John W. Heinrich

Publikováno v: Journal of Great Lakes Research. 47:S297-S309

A successful management plan requires clear goals and a process for evaluation. Without them, managers risk operational shifts in which continuous changes disguised as improvements may have little beneficial effect. The conception, design, and operat

Evaluation of Strategies for the Release of Male Sea Lampreys (Petromyzon marinus) in Lake Superior for a Proposed Sterile-Male-Release Program

Autor: John W. Heinrich, Cheryl A. Kaye, Jeffrey W. Slade, Joseph H. Genovese, Rodney B. McDonald, William D. Swink, Lee H. Hanson

Publikováno v: Journal of Great Lakes Research. 29:424-434

Successful implementation of a sea lamprey (Petromyzon marinus) control technique that uses sterilized males to reduce reproduction presently depends on the importation of large numbers of males outside of the target population. Strategies were exami

The international sea lamprey (Petromyzon marinus) control program successfully laid the foundation for rehabilitation of lake trout (Salvelinus namaycush) in Lake Superior and was well coordinated among management agencies during 1957–1999. The la

Reduction in Sea Lamprey Hatching Success Due to Release of Sterilized Males

Autor: Roger A. Bergstedt, Rodney B. McDonald, Robert J. Young, Katherine M. Mullett, Michael B. Twohey, John W. Heinrich

Publikováno v: Journal of Great Lakes Research. 29:435-444

Male sea lampreys (Petromyzon marinus), sterilized by injection with bisazir, were released in Lake Superior tributaries from 1991 to 1996 and exclusively in the St. Marys River (the outflow from Lake Superior to Lake Huron) since 1997 as an alternat

Passage of Four Teleost Species Prior to Sea Lamprey (Petromyzon marinus) Migration in Eight Tributaries of Lake Superior, 1954 to 1979

Autor: Gregory L. Klingler, John W. Heinrich, Jean V. Adams

Publikováno v: Journal of Great Lakes Research. 29:403-409

Seasonally operated barriers in rivers are used by the Great Lakes Fishery Commission to block adult sea lamprey (Petromyzon marinus) migrations, yet pass other fish during some part of the year. Knowledge of the overlap of spawning migrations of sea

Publikováno v: Journal of Great Lakes Research. 29:552-565

As part of the sea lamprey control program in the Great Lakes, a suite of about 150 sea lamprey producing streams have been regularly treated with the lampricide 3-trifluoromethyl-4-nitrophenol (TFM) every 3 to 5 years since 1958. State, provincial,

Assessing Assessment: Can the Expected Effects of the St. Marys River Sea Lamprey Control Strategy Be Detected?

In 1997 the Great Lakes Fishery Commission approved a 5-year (1998 to 2002) control strategy to reduce sea lamprey (Petromyzon marinus) production in the St. Marys River, the primary source of parasitic sea lampreys in northern Lake Huron. An assessm

Techniques and Methods for Estimating Abundance of Larval and Metamorphosed Sea Lampreys in Great Lakes Tributaries, 1995 to 2001

Publikováno v: Journal of Great Lakes Research. 29:137-151

Before 1995, Great Lakes streams were selected for lampricide treatment based primarily on qualitative measures of the relative abundance of larval sea lampreys, Petromyzon marinus. New integrated pest management approaches required standardized quan

Do Toxic Substances Pose a Threat to Rehabilitation of Lake Trout in the Great Lakes? A Review of the Literature

Autor: William W. Taylor, Al Sippel, Ted Schaner, Carol C. Edsall, Dennis S. Lavis, John W. Heinrich, Leon M. Carl, Michaela Zint

Publikováno v: Journal of Great Lakes Research. 21:530-546

Toxic substances have been suspected of being one of the causes of Great Lakes lake trout reproductive failure. Because toxic substances are present in the Great Lakes basin, managers should be aware of the role of contaminants in preventing lake tro
