For over 50 years, invasive sea lamprey Petromyzon marinus populations have been controlled in the Great Lakes using the pesticide 3-trifluoromethyl-4-nitrophenol (TFM), which is applied to streams containing larval sea lampreys. The specificity of T

This study evaluated responses by migratory spawning-phase sea lampreys Petromyzon marinus to artificial trap lighting in the laboratory and field with the aim of improving trapping as a method of sea lamprey control in the Laurentian Great Lakes. We

We analyzed historical trapping records from six Lake Ontario tributaries to (1) compare the relative importance of water temperature, water level, and lunar cycle to migratory activity in upstream-migrating sea lampreys Petromyzon marinus and (2) de

Light avoidance in larval lampreys is mediated by dermal photoreceptors located in the tail. These photoreceptors continue to function in adults, but they seem redundant because post-metamorphic lampreys possess well-developed eyes. This study examin

This study used controlled laboratory conditions to directly assess the role of temperature in controlling diel activity in sexually immature, upstream migrant sea lampreys ( Petromyzon marinus ). Our results identified three separate temperature-ind

This paper is one of a series supported by the Great Lakes Fishery Commission that describe research priorities related to each facet of the sea lamprey control program (assessment, pheromones, barriers and trapping, sterile males and lampricides). T

The development of chronic metal toxicity models for fresh water fish is complicated by the physiological adjustments made by the animal during exposure which results in acclimation. This study examines the influence of a pre-exposure to a chronic su

The effects of different ligands on the bioavailability of dietary copper (Cu) and zinc (Zn) to fish have not been thoroughly investigated. We therefore exposed juvenile rainbow trout (Oncorhynchus mykiss; ~200 mg body weight) to control food or to f

Concentrations of Cd, Cu, and Zn were determined in various organs of juvenile yellow perch (Perca flavescens) collected from eight lakes located along a metal concentration gradient. Metal exposure was evaluated on the basis of the free ambient Cd2+

The objective of this study was to evaluate the effects of copper exposure on swimming performance and gill-binding characteristics of wild yellow perch (Perca flavescens), a species endemic to metal-contaminated lakes of the Sudbury region in northe
