Lake Sturgeon Biology in Rainy Lake, Minnesota and Ontario
Rainy Lake contains a native population of lake sturgeon Acipenser fulvescens that has gone largely unstudied. The objectives of this study were to document the population characteristics of lake sturgeon in Rainy Lake, determine spawning locations and generalized lake sturgeon movement patterns …

GROWTH PATTERNS AND SIZE-GROUP INTERACTIONS IN HATCHERY-REARED AGE-0 LAKE STURGEON
<p>Raising lake sturgeon (<em>Acipenser fulvescens</em>) in hatcheries is an important tool for rehabilitation and conservation, but is expensive. When hatchery sturgeon do not grow large enough before stocking, their odds of survival decline significantly and resources are wasted. We investigated …

Identification and Genetic Diversity of Lake Sturgeon Larvae on Artificial Reefs in the Huron-Erie Corridor
There are 27 species of sturgeon worldwide and most are currently extinct, endangered or threatened. Lake sturgeon, Acipenser fulvescens, one of the oldest species on the planet, evolved about 136 million years ago, and have had little morphological change, and are endemic to the freshwater lakes …

Lake Sturgeon (Acipenser fulvescens) Population Attributes, Reproductive Structure, and Distribution in Namakan Reservoir, Minnesota and Ontario
Population declines of lake sturgeon (Acipenser fulvescens) have resulted in their protected status as a species of special concern in the state of Minnesota and threatened in the province of Ontario. Water bodies that lie along the Minnesota-Ontario border are home to historic populations of lake …

DELAYED EFFECTS OF SUB-LETHAL LAMPRICIDE, 3-TRIFLUOROMETHYL-4-NITROPHENOL (TFM), EXPOSURE ON THE METABOLIC PHYSIOLOGY OF JUVENILE LAKE STURGEON (<em>ACIPENSER FULVESCENS</em>)
… (TFM) can be lethal to juvenile lake sturgeon (<em>Acipenser fulvescens)</em> at high concentrations used to control invasive sea lamprey (<em>Petromyzon marinus)</em>. Little is known about how TFM would affect juvenile lake sturgeon (age-0) at the sub-lethal concentrations …

Understanding links between flow regime and fish populations in the Saskatchewan River Delta
… cultural importance (Walleye Sander vitreus and Lake Sturgeon Acipenser fulvescens) in the Saskatchewan River Delta. To estimate the annual recruitment of Walleye, aging structures were removed from fish sampled from the commercial fishery at Cumberland Lake, Saskatchewan. Cohort strength was …

Investigating ecosystem-level effects of gillnet bycatch in Lake Erie: implications for commercial fisheries management
Lake Erie supports one of the world's largest freshwater commercial fisheries. Bycatch has become a concern in current fisheries management. This study focused on four species in Lake Erie that include two major commercial and recreational species, walleye (Sander vitreus) and yellow perch (Perca …

GEOSPATIAL MODELLING OF PRAIRIE RIVERS: LINKING PHYSICAL INDICATORS OF FISH HABITAT TO LARGE SCALE GEOMORPHIC PATTERNS IN RIVER SYSTEMS USING GEOMORPHIC RESPONSE UNITS (GRU)
… Geomorphic Response Unit (GRU) methodology, and Lake Sturgeon overwintering locations in the South Saskatchewan and Saskatchewan Rivers. Habitat selection ratios suggest that Lake Sturgeon in the Upper South Saskatchewan River significantly selected for one of seven possible Types for …
