Abstract:
... Atlantic sturgeon and shortnose sturgeon co-occur in many estuaries along the Atlantic Coast of North America. Both species are protected under the U.S. Endangered Species Act and internationally on the IUCN Red list and by CITES. Early life-stages of both sturgeons may be exposed to persistent aromatic hydrocarbon contaminants such as PCBs and PCDD/Fs which are at high levels in the sediments of ...

Subject:
Acipenser fulvescens; adults; genetic variation; genotyping; gillnets; life history; loci; protocols; rivers; sturgeon; Ontario
Abstract:
... Lake Sturgeon, Acipenser fulvescens, was assessed in a large, pristine river in northern Canada using a standardized protocol. Gill netting (38‐127 mm and 204‐306 mm stretched mesh) was conducted at five sites averaging 37 rkm in the Attawapiskat River in Ontario. The objectives were to ascertain relative abundance of Lake Sturgeon within a northern river; determine if Lake Sturgeon are randomly d ...

Abstract:
... The objective was to investigate the effects of two native fish predators (adult rock bass Ambloplites rupestris, and smallmouth bass Micropterus dolomieue) and an invasive benthic crayfish (Orconectes rusticus) on habitat choice and survival of hatchery‐reared age‐0 lake sturgeon (Acipenser fulvescens). Three length‐classes (mean total length ± 1 SD) of 68.4 ± 12.7 cm, 85.9 ± 15.0, and 111.6 ± 15 ...

Abstract:
... Lake sturgeon (Acipenser fulvescens) occupy some of the most northerly distributions of any sturgeon species and experience extended overwintering periods when resources may be limited. Conservation stocking is currently used as a management tool to enhance lake sturgeon populations that are at risk or endangered. One of the most limiting components of the conservation effort is our understanding ...

Abstract:
... Whereas lake sturgeon Acipenser fulvescens stocking began in the Cumberland River system in 2006, reservoir‐specific data are needed to assess restoration efforts as well as provide information to support sturgeon management decisions. The purpose of this study was to (i) assess dam passage and emigration rates of tagged hatchery‐reared juvenile lake sturgeon through the Cheatham and Old Hickory l ...

Abstract:
... The primary objective of this study was to use direct (acoustic telemetry) and indirect (genetic assignment) methods to characterize basic aspects of lake sturgeon (Acipenser fulvescens Rafinesque, 1817) breeding ecology. Specifically, data on natal origin, spawning habitat, spawn sex‐size structure, and sex‐specific residence times, spawning site fidelity, seasonal movements and degree of strayin ...

Abstract:
... Population levels of recruitment are often affected by high rates of mortality during early life stages. Lake sturgeon (Acipenser fulvescens), a regionally threatened species, experiences high rates of mortality during the larval stage, partially due to predation. The objective of this study was to quantify and compare relative rates of larval sturgeon predation by piscine predators in the upper B ...

Abstract:
... Namao virus (NV) is a sturgeon nucleocytoplasmic large DNA virus (sNCLDV) that can cause a lethal disease of the integumentary system in lake sturgeon Acipenser fulvescens. As a group, the sNCLDV have not been assigned to any currently recognized taxonomic family of viruses. In this study, a data set of NV DNA sequences was generated and assembled as two non-overlapping contigs of 306,448 bp and t ...

Abstract:
... Sturgeon species are imperiled world-wide by a variety of anthropogenic stressors including chemical contaminants. Atlantic sturgeon, Acipenser oxyrinchus, and shortnose sturgeon, Acipenser brevirostrum, are largely sympatric acipenserids whose young life-stages are often exposed to high levels of benthic-borne PCBs and PCDD/Fs in large estuaries along the Atlantic Coast of North America. In previ ...
