WDFW Washington State Status Report for the Bald Eagle
STATE OF WASHINGTON October 2001 WashingtonWashington StateState StatusStatus ReportReport forfor thethe BaldBald EagleEagle by Derek W. Stinson, James W. Watson and Kelly R. McAllister Washington Department of FISH AND WILDLIFE Wildlife Program WDFW 759 The Washington Department of Fish and Wildlife maintains a list of endangered, threatened and sensitive species (Washington Administrative Codes 232-12-014 and 232-12-011, Appendix I). In 1990, the Washington Fish and Wildlife Commission adopted listing procedures developed by a group of citizens, interest groups, and state and federal agencies (Washington Administrative Code 232-12-297, Appendix I). The procedures include how species listing will be initiated, criteria for listing and delisting, public review and recovery and management of listed species. The first step in the process is to develop a preliminary species status report. The report includes a review of information relevant to the species’ status in Washington and addresses factors affecting its status including, but not limited to: historic, current, and future species population trends, natural history including ecological relationships, historic and current habitat trends, population demographics and their relationship to long term sustainability, and historic and current species management activities. The procedures then provide for a 90-day public review opportunity for interested parties to submit new scientific data relevant to the draft status report and classification recommendation. During the 90-day review period, the Department held three public meetings to take comments and answer questions. The Department has now completed the final status report, listing recommendation and State Environmental Policy Act findings for presentation to the Washington Fish and Wildlife Commission. -
Winter Populations, Behavior, and Seasonal Dispersal of Bald Eagles in Northwestern Illinois
WINTER POPULATIONS, BEHAVIOR, AND SEASONAL DISPERSAL OF BALD EAGLES IN NORTHWESTERN ILLINOIS WILLIAM E. SOUTHERN s a result of efforts by Bent (1937)) Broley (1952)) Herrick (1924, A 1932, and 1933), Imler (1955)) and others, numerous data on the Bald Eagle (Haliaeetus Zeucocephalus) are available. Little of the published information, however, pertains to the winter habits of the species or to winter population dynamics and seasonal movements. Between 27 November 1961 and 1 April 1962, at the Savanna Army Depot, Carroll and Jo Daviess counties, Illinois, my assistants and I spent 232 hours observing and attempting to trap eagles. Additional time was devoted to other aspects of the project (making and setting traps, securing bait, etc.). On several occasions we spent the entire daylight period in the area. The study area extended for 14 miles along the Mississippi River and its backwaters and sloughs, which were proliferated with islands (Fig. 1). Most of the slightly rolling terrain bordering the river was covered by deciduous forest. The trees along a portion of the main channel had been thinned to the point that the area (between points 1 and 2, Fig. 1) resembled a park. The study area represented only a small part of the habitat suitable for eagles near Savanna; however, it probably had the greatest abundance of food and, there- fore, eagles (we observed only four outside the Depot; three of these during spring dispersal). The concentrations reported during our study were larger than those reported elsewhere in the state. My objectives were to record behavior, live-trap, color-mark, and determine the movements of Bald Eagles during the winter and early spring. -
Shad in the Schools, NC
Attachment 1 Food Web Activity Student Sheet Background Information: Shad in the Schools, N.C. The coastal rivers and shallow marine environments along the coast of North Carolina are home to complex ecosystems. Within these freshwater and saltwater ecosystems there is an intimate relationship between many different producers and consumers. These produces and consumers create an interconnected food web. Each organism is dependent on clean water, oxygen, and healthy riparian corridors on the lands adjacent to these waters. The disruption of just one component of any food web can disturb all living things, including humans. American shad, a member of the herring family, is one species of fish that plays a critical role in the river and near shore shallow marine ecosystems of North Carolina. Shad are an anadromous species, meaning they live in the ocean but return to the rivers of North Carolina in the spring to spawn, or reproduce, each spring. This means that shad serve as a food source for many animals living in both inland freshwater and marine environments. Predators of shad include other fishes such as striped bass and king mackerel, bald eagles, bottlenose dolphin, and humans. Bald eagles have evolved to raise their young at the same time that anadromous fishes, such as shad, return to the rivers to spawn so that the young eaglets will have a plentiful food source. This evolutionary trait highlights the connectivity that can be found within food webs. Bald Eagles can be viewed now through a new technology, web cams.

American Shad at Home American Shad-Themed Activities for Students and Their Caregivers to Complete at Home
American Shad at Home American shad-themed activities for students and their caregivers to complete at home. Early Learners (K-2nd) 1. American shad are a type of fish! But what is a fish, and what things do all fish have in common? Visit this webpage from National Geographic to learn more about fish and spend time looking closely at the photographs of the different kinds of fish. Make a list of the things that fish have in common. For example, do all fish have fins? Next, make a list of all the things you and fish have in common. For example, do fish have eyes? What about bones? You can create your lists by writing words or drawing pictures. 2. Birds like bald eagles and osprey hunt for fish, including American shad! Can you help this eagle find fish by completing this maze? If you have a printer at home, you can print the maze. If you don’t, you can use your finger to trace the route the eagle should take on a computer, tablet, or phone screen. 3. American shad travel long distances throughout their life – from the rivers where they were born, out to the ocean, and back again! Shad may encounter many obstacles on their journey: predators like dolphins and eagles that want to eat them, dams and locks that prevent them from getting where they need to go, rough water and strong currents that make it hard to swim, etc. Create your own obstacle course at home using materials you already have: sheets, pillows, blankets, blocks, cardboard boxes, etc. -
Proceedings of the Indiana Academy of Science 1 1 8(2): 143—1 86
2009. Proceedings of the Indiana Academy of Science 1 1 8(2): 143—1 86 THE "LOST" JORDAN AND HAY FISH COLLECTION AT BUTLER UNIVERSITY Carter R. Gilbert: Florida Museum of Natural History, University of Florida, Gainesville, Florida 32611 USA ABSTRACT. A large fish collection, preserved in ethanol and assembled by Drs. David S. Jordan and Oliver P. Hay between 1875 and 1892, had been stored for over a century in the biology building at Butler University. The collection was of historical importance since it contained some of the earliest fish material ever recorded from the states of South Carolina, Georgia, Mississippi and Kansas, and also included types of many new species collected during the course of this work. In addition to material collected by Jordan and Hay, the collection also included specimens received by Butler University during the early 1880s from the Smithsonian Institution, in exchange for material (including many types) sent to that institution. Many ichthyologists had assumed that Jordan, upon his departure from Butler in 1879. had taken the collection. essentially intact, to Indiana University, where soon thereafter (in July 1883) it was destroyed by fire. The present study confirms that most of the collection was probably transferred to Indiana, but that significant parts of it remained at Butler. The most important results of this study are: a) analysis of the size and content of the existing Butler fish collection; b) discovery of four specimens of Micropterus coosae in the Saluda River collection, since the species had long been thought to have been introduced into that river; and c) the conclusion that none of Jordan's 1878 southeastern collections apparently remain and were probably taken intact to Indiana University, where they were lost in the 1883 fire. -
American Shad Life History
American Shad Life History, (when and where do they spawn, where do they live, what do they eat, what are their predators , how old do they get, where do they go, how do we know?) How do we know all this about American Shad? Answer = Mostly from college students (students doing research as part of their educational requirements for fishery science graduate degrees at universities in North Carolina. Above are graduate students from NCSU and on the left is a professor at East Carolina University who has taught many students with research projects Above are nets that can be as well. lowered off bridges to collect eggs and larvae from the water Dr. Joe Hightower at NCSU has had several students that have contributed to as the current flows under the understanding American shad in our rivers and Dr. Roger Rulifson has had Bridge. students as well that contributed greatly to our understanding of American shad movement patterns. This is a great situation because it helps educate students and helps them develop work experience that makes it easier for them to find jobs. A How do we know where they go? American shad with dart tag with identification numbers. Tagging fish allowed biologists to learn where American shad lived at different times. More recently some fish have been tagged with implanted transponders that can be detected by remote sensors placed along the rivers. Transponder tags are also used by veterinarians in dogs and cats so that if you lose your pet the pet’s information owner / address are always with the pet in case they are found, but have lost their collar tags. -
Connecticut River American Shad Management Plan
CONNECTICUT RIVER AMERICAN SHAD MANAGEMENT PLAN Connecticut River Atlantic Salmon Commission 103 East Plumtree Road Sunderland, Massachusetts 01375 Management Plan Approved June 9, 2017 Addendum on Fish Passage Performance Approved February 28, 2020 INTRODUCTION The Connecticut River population of American Shad has been cooperatively managed by the basin state and federal fishery agencies since 1967. In that year the “Policy Committee for Fishery Management of the Connecticut River Basin” was formed in response to the passage of the 1965 Anadromous Fish Conservation Act (Public Law 89-304) by the U.S. Congress. This committee was replaced by the more formal “Connecticut River Atlantic Salmon Commission” (CRASC), which was created by act of Congress (P.L. 98-138) in 1983 (Gephard and McMenemy 2004) and coordinates restoration and management activities with American Shad (http://www.fws.gov/r5crc/). The CRASC American Shad Management Plan had a stated objective of 1.5 to 2.0 million fish entering the river mouth annually (CRASC 1992). Diverse legislative authorities for the basin state and federal fish and wildlife agencies, including formal agreements to restore and manage American Shad, have been approved over time and are listed in Appendix A. The following Plan updates the existing CRASC Management Plan for American Shad in the Connecticut River Basin (1992), in order to reflect current restoration and management priorities and new information. An overview of American Shad life history and biology is provided in Appendix B. Annual estimates of adult returns to the river mouth for the period 1966-2015 have ranged from 226,000 to 1,628,000, with an annual mean of 638,504 fish (Appendix C). -
American Shad (Alosa Sapidissima)
American Shad (Alosa sapidissima) Family Clupeidae, Herrings Common names: shad, Atlantic shad, white shad Description: American shad are dark blue to green above with paler sides and a silver underbelly. Behind the upper edge of their gill cover is a large dusky spot that is usually followed by several small, less distinct, dusky spots. These fish have a laterally compressed body and a deeply forked tail fin. The midline of their belly is saw edged and sharp and their scales are large. They have only one dorsal fin and one anal fin. American shad are the largest members of the true herring family and can grow to 30 inches in length and weigh over 9 pounds. Where found: inshore Similar Gulf of Maine species: Atlantic herring, alewife, blueback herring, Atlantic menhaden Remarks: American shad are anadromous fish. Commonly known as 'the poor man's tarpon," shad are highly sought after as a sportfish because of their feisty nature and their ability to leap. The most popular time of year to go shad fishing is in the spring when these fish are returning to their coastal streams and rivers to spawn. Although shad are primarily plankton feeders, they will take a variety of baits, lures and flies. Either light spinning or fly fishing gear is recommended.

If I Catch It, Can I Eat
This pamphlet will give you information that will help your If I Catch It, family avoid chemicals in fish and eat fish safely. Fish from Connecticut’s waters are a healthy, low-cost source of protein. Can I Eat It? Unfortunately, some fish take up chemicals such as mercury and polychlorinated biphenyls (PCBs). These chemicals can build up in your body and increase health risks. The developing fetus and young children are most sensitive. Women who eat A Guide to Eating Fish Safely fish containing these chemicals before or during pregnancy or nursing may have 2020 Connecticut Fish Consumption Advisory children who are slow to develop and learn. Long term exposure to PCBs may increase cancer risk. What Does The Fish Consumption Advisory Say? The advisory tells you how often you can safely eat fish from Connecticut’s waters and from a store or restaurant. In many cases, separate advice is given for the High Risk and Low Risk Groups. • You are in the High Risk Group if you are a pregnant woman, a woman who could become pregnant, a nursing mother, or a child under six. • If you do not fit into the High Risk Group, you are in the Low Risk Group. Advice is given for three different types of fish consumption: 1. Statewide FRESHWATER Fish Advisory: Most freshwater fish in Connecticut contain enough mercury to cause some limit to consumption. The statewide freshwater advice is that: • High Risk Group: eat no more than 1 meal per month • Low Risk Group: eat no more than 1 meal per week 2.
