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.

Iowa State Co•servcttion(•ommissio,•, Des Moit•cs, Iowa .•BSTRACT The stmnaeh contents of 912 channel catfish (769 containing food) taken iu a short section of the Des Moines River from September, 1940, to October, 1911, are analyzed. The physical and biotic elmraeteristies of the study area are described; a partial list of the fishes present together xvith comments on their importance and relative abundance is included. The ehanuet eatfish is omnivorous, as is revealed by a review of the pertinent literature and by this study. A wide wtriety of organisms is eaten (some 50 families of insects alone are represented--these are listed). Insects and fish serve as staple foods, plant seeds are taken i• season, and various other items are eaten in limited numbers. The principal groups of foods (insects, fish, plants, and miscellaneous) are anMyzed volumetrically, by œrequeney of occurrence, and numerically. In the area studied, catfish grow at a rate of about 4 inches a year during the first 3 years of life (determined by length-frequency analysis). These natural size groups are utilized to establish the relationship between size and food habits. Young fish feed ahnost exclusively on aquatic insect larvae--chiefly midges, blackflies, mayflies, and enddis flies. In fish frmn 4 to 12 inches lo•g insects continue to make up the bulk of the food, but at progressively greater size larger insects (mayflies and caddis flies) are eaten with increasing frequency and dipterans are of less importonce than in the smaller size group; snmll fish and plant seeds become significant items of diet. -
Invasive Catfish Management Strategy August 2020
Invasive Catfish Management Strategy August 2020 A team from the Virginia Department of Game and Inland Fisheries uses electrofishing to monitor invasive blue catfish in the James River in 2011. (Photo by Matt Rath/Chesapeake Bay Program) I. Introduction This management strategy portrays the outcomes of an interactive workshop (2020 Invasive Catfish Workshop) held by the Invasive Catfish Workgroup at the Virginia Commonwealth University (VCU) Rice Rivers Center in Charles City, Virginia on January 29-30, 2020. The workshop convened a diverse group of stakeholders to share the current scientific understanding and priority issues associated with invasive catfishes in Chesapeake Bay. The perspectives shared and insights gained from the workshop were used to develop practical, synergistic recommendations that will improve management and mitigate impacts of these species across jurisdictions within the watershed. Blue catfish (Ictalurus furcatus) and flathead catfish (Pylodictis olivaris) are native to the Ohio, Missouri, Mississippi, and Rio Grande river basins, and were introduced into the Virginia tributaries of Chesapeake Bay in the 1960s and 1970s to establish a recreational fishery. These non-native species have since spread, inhabiting nearly all major tributaries of the Bay watershed. Rapid range expansion and population growth, particularly of blue catfish, have led to increasing concerns about impacts on the ecology of the Chesapeake Bay ecosystem. 1 Chesapeake Bay Management Strategy Invasive Catfish Blue and flathead catfishes are long-lived species that can negatively impact native species in Chesapeake Bay through predation and resource competition. Blue catfish are generalist feeders that prey on a wide variety of species that are locally abundant, including those of economic importance and conservation concern, such as blue crabs, alosines, Atlantic menhaden, American eels, and bay anchovy. -

A Brief Diet Analysis of Common Carp and Channel Catfish by Brent Campos
A Brief Diet Analysis of Common Carp and Channel Catfish By Brent Campos Four mainstem nonnative fish, two channel catfish (Ictalurus punctatus) and two common carp (Cyprinus carpio), were captured using hook-and-line during our research expedition down the Grand Canyon in March, 2005. The stomachs of the fish were removed and their contents analyzed. The two species of fish appeared to exhibit divergent methods of feeding, despite having very similar organisms in their stomachs. Catfish displayed a selective, possibly mid-water picking strategy, while carp appeared to be consuming benthic substrates with their prey. Figure 1. The 405 mm common carp with its abdominal cavity cut open. Note the large ovaries, which are yellow and grainy in appearance (photo: Chris Hammersmark). One common carp was caught near sunset in a small eddy near Bass Camp at river mile 108 on March 21. It was male, measured 370 mm standard length (SL) and exhibited spawning colors. Identifiable stomach contents included aquatic Coeloptra (beetles), one oligochete, many pebbles, and detritus, among other benthic inverts. The presence of numerous pebbles indicates this fish was probing substrates for food, as would be expected for this species. The second common carp was caught near the mouth of the backwater at river mile 137, which was at the separation point of the eddy that created the site’s sandbar. The carp was female, 405 mm in length (standard length), and displayed spawning colors. Her ovaries made up approximately 50% of her abdominal cavity by volume. Gut contents were comprised of 95% algae and 5% a mix of detritus and aquatic invertebrates.
