Fish
(Diadromous, Freshwater, and Saltwater) - Fish, aquatic vertebrates which are covered in scales and equipped with fins (paired and unpaired), are found in all types of aquatic environments ranging from freshwater to saltwater. Diadromous fish are those that travel between fresh and saltwater (Pacific salmon, for example, which is an anadromous fish that breeds in freshwater but lives in the sea, mostly). Monitoring the abundances of the prey fish populations is critical to managing the lake ecosystem. Presently, salmonines are stocked into the lake to supplement and sustain their populations within the lake.

Native fish sanctuaries of the Lower Colorado River: Cibola High Levee Pond Desert Pupfish Pond

2005 | Publisher: USGS | Science Center: Fort Collins Science Center (FORT, Ft. Collins) | Format: URL

www.fort.usgs.gov — Historically, the Colorado River was one of the most formidable rivers in the world. Each spring, melting snow from the mountains scoured the desert landscape moving millions of tons of sediment to the sea. The Grand Canyon lays testament to its erosive nature. Summer heat would bring seasonal droughts, reducing the river to a trickle impacting More...

Development of Methods to Determine the Reproductive Status of Pallid Sturgeon in the Missouri River

Publisher: USGS | Science Center: Columbia Environmental Research Center (CERC, Columbia) | Format: URL

www.cerc.usgs.gov — This research project focuses on the endemic nature of the Pallid sturgeon (Scaphirhynchus albus) and shovelnose sturgeon (Scaphirhynchus platorynchus) and their reproductive status. Its objectives are to develop methods to use endoscopy and ultrasonic imagery to visually observe the gonads of adult and immature shovelnose and pallid sturgeon, as More...

Fish Health and Reproductive Studies at Lake Erie Areas of Concern

Publisher: USGS | Science Center: Leetown Science Center (LSC, Kearneysville) | Format: URL

www.lsc.usgs.gov — This is a research project whose primary objective is to assess the health of selected fish species (brown bullhead and largemouth bass) and compare these findings with historic information on fish health in the individual rivers and with concurrent samples collected at reference sites. A secondary objective is to compare and correlate the fish More...

Effects of estrogen and related contaminants on the expression of genes involved in the innate immune system of fish in rivers of the Chesapeake Bay Drainage

Publisher: USGS | Science Center: Leetown Science Center (LSC, Kearneysville) | Format: URL

www.lsc.usgs.gov — This research project measures the effects of estrogen and related contaminants on the expression of genes involved in the innate immune system of fish in rivers of the Chesapeake Bay Drainage. This project begs the question of whether or not hepcidin are expression and iNOS expression induced upon exposure to bacteria, and whether this induction More...

Development of a Bioassay to Quantify Vitellogenin in the Endangered Razorback Sucker followed by Annual Cycle Characterization of Vitellogenin and Steroid Hormones as a Measure of Reproductive Health

Publisher: USGS | Science Center: Columbia Environmental Research Center (CERC, Columbia) | Format: URL

www.cerc.usgs.gov — This research project objective is to measure vtg and steroid hormones in sexually mature, adult razorback sucker over one annual -estradiol,ß reproductive cycle. We will measure vtg and steroid hormones (17 11-ketotestosterone, and testosterone) in blood plasma of razorback suckers once a month for one year to document concentrations throughout More...

Preliminary review of adaptation options for climate-sensitive ecosystems and resources - A Report by the U.S. Climate Change Science Program and the Subcommittee on Global Change Research

June 20 2008 | Publisher: USGS | Science Center: Fort Collins Science Center (FORT, Ft. Collins) | Format: URL

www.fort.usgs.gov — This report provides a preliminary review of adaptation options for climate-sensitive ecosystems and resources in the United States. The term "adaptation" in this document refers to adjustments in human social systems (e.g., management) in response to climate stimuli and their effects. Since management always occurs in the context of desired More...

Investigation of Organic Chemicals Potentially Responsible for Mortality and Intersex in Fish of the North Fork of the Shenandoah River, Virginia, during Spring of 2007

2008 | Publisher: USGS | Format: URL

pubs.usgs.gov — This study determined that concentrations of persistent hydrophobic contaminants, such as polycyclic aromatic hydrocarbons (< picograms per liter), legacy pesticides (<10 picograms per liter), and polychlorinated biphenyls (<280 picograms per liter) were low and indicative of a largely agricultural area. Atrazine and simazine were the most More...
