American Eel (Anguilla Rostrata)
Indiana Division of Fish and Wildlife’s Animal Information Series American Eel (Anguilla rostrata) Do they have any other names? The names “glass eel” or “elver” are used to describe young, developing eels. Why are they called American eels? The closest relatives to the American eel are other freshwater eels found in Europe and Asia; therefore they are called American eels because they are only in America. Anguilla is the Latin name for eel and rostrata is Latin for “beaked,” in reference to the snout. What do they look like? American eels are a brownish-colored fish with a slender, snake-like body and a small, pointed head. The body appears smooth and mucousy; however there are small scales present. They have a long dorsal fin that is more than half the length of the body and attached to the tail and anal fins. American eels do not have pelvic fins, but do have pectoral fins (on the sides near the head). The lower jaw projects farther than the upper jaw and they have many small teeth. Photo Credit: Duane Raver/USFWS 2012-MLC Page 1 Where do they live in Indiana? American eels are rare in Indiana and are found in large streams and rivers. They can sometimes be found in ponds or lakes that are not connected to a river, although this seldom happens. What kind of habitat do they need? American eels are found in large streams or rivers with continuous flow and clear water. During the day eels like to stay near logs, boulders, or other cover. -
American Eel Anguilla Rostrata Contributor: John W
American Eel Anguilla rostrata Contributor: John W. McCord DESCRIPTION: Taxonomy and Basic Description The American eel, Anguilla rostrata (Lesueur 1817), belongs to the freshwater eel family, Anguillidae. Related species occur throughout the world, but the American eel is the only North American anguillid eel. Eels are snake-shaped and covered with a mucous layer that renders them slimy to the touch despite the presence of minute scales. A continuous, low fin runs from the middle of the back, around the tail, and ends behind the vent. Relatively small pectoral fins originate near the animals midline and immediately posterior to the head and gill-covers. Coloration varies with stage of maturity and habitat, but eels are generally dark olive, yellowish or slate-gray above and light below. Eels from dark, tannic acid streams are darker while those from clear streams and estuaries are lighter (pers. obs.). The American eel is catadromous; it spawns in oceanic waters but uses freshwater, brackish and estuarine systems for most of its developmental life. Sexually mature adults, called silver eels, migrate from freshwater to the sea in fall. Their destination for spawning is the Sargasso Sea, an expansive portion of the central North Atlantic Ocean, east of the Bahamas and south of Bermuda. Adults are thought to die after spawning. The largest females produce nearly 20 million eggs (Barbin and McCleave 1997). Mature females in the southern portion of the eel’s range are generally smaller and carry as few as 400,000 eggs (Wenner and Musick 1974). Eggs hatch into a brief pre-larval stage before transformation into the active leptocephalus stage. -

This field guide is largely based on material prepared for training courses on elasmobranch identification delivered in the region by the first author, and promoted by the Regional Organization for the Conservation of the Environment of the Red Sea and Gulf of Aden (PERSGA), as an activity of PERSGA’s Strategic Action Programme (SAP) towards capacity building and technical assistance in the Red Sea and Gulf of Aden region. Printing was supported by Japanese Government funds. The increasing recognition of the significance of sharks and batoid fishes as ecosystem health indicators, as well as their particular importance in exploited ecosystems in the Red Sea and the Gulf of Aden, have been key considerations to promote the preparation of this Field Guide. Furthermore, in recent years the reported catches of elasmobranchs in the Red Sea and the Gulf of Aden showed a marked increase. -

American Eel (Anguilla Rostrata )
American Eel (Anguilla rostrata ) Abstract The American eel ( Anguilla rostrata ) is a freshwater eel native in North America. Its smooth, elongated, “snake-like” body is one of the most noted characteristics of this species and the other species in this family. The American Eel is a catadromous fish, exhibiting behavior opposite that of the anadromous river herring and Atlantic salmon. This means that they live primarily in freshwater, but migrate to marine waters to reproduce. Eels are born in the Sargasso Sea and then as larvae and young eels travel upstream into freshwater. When they are fully mature and ready to reproduce, they travel back downstream into the Sargasso Sea,which is located in the Caribbean, east of the Bahamas and north of the West Indies, where they were born (Massie 1998). This species is most common along the Atlantic Coast in North America but its range can sometimes even extend as far as the northern shores of South America (Fahay 1978). Context & Content The American Eel belongs in the order of Anguilliformes and the family Anguillidae, which consist of freshwater eels. The scientific name of this particular species is Anguilla rostrata; “Anguilla” meaning the eel and “rostrata” derived from the word rostratus meaning long-nosed (Ross 2001). General Characteristics The American Eel goes by many common names; some names that are more well-known include: Atlantic eel, black eel, Boston eel, bronze eel, common eel, freshwater eel, glass eel, green eel, little eel, river eel, silver eel, slippery eel, snakefish and yellow eel. Many of these names are derived from the various colorations they have during their lifetime. -

Natural Mortality and Size Structure of Introduced Blue Catfish in Virginia Tidal Rivers
Introduced Blue Catfish Mortality and Size Structure . Hilling et al. Natural Mortality and Size Structure of Introduced Blue Catfish in Virginia Tidal Rivers Corbin D. Hilling, Department of Fish and Wildlife Conservation, Virginia Polytechnic Institute and State University, Blacksburg, VA 24061 Aaron J. Bunch, Virginia Department of Game and Inland Fisheries, Charles City, VA 23030 Robert S. Greenlee, Virginia Department of Game and Inland Fisheries, Charles City, VA 23030 Donald J. Orth, Department of Fish and Wildlife Conservation, Virginia Polytechnic Institute and State University, Blacksburg, VA 24061 Yan Jiao, Department of Fish and Wildlife Conservation, Virginia Polytechnic Institute and State University, Blacksburg, VA 24061 Abstract: In the 1970s and 1980s, blue catfish Ictalurus( furcatus) were introduced to the tidal rivers of Virginia. Current abundances and uncertainty about population characteristics of blue catfish generated concern for other economically important and imperiled species. We estimated natural mor- tality and size structure of blue catfish for four tidal river systems (i.e., James, Mattaponi, Pamunkey and Rappahannock). Using common empirical estimators with pooled data from the period 2002–2016, we calculated five estimates of natural mortality. Proportional size distributions were used to examine changes in size structure over time. Maximum observed age of 25 years indicated mature populations. Estimated mean instantaneous natural mortality (M) from five empirical estimators ranged from 0.13–0.19 in the four rivers. Temporal trends in size structure differed among rivers, likely due to differences in stocking timing and riverine productivity. Proportions of memorable and trophy size blue catfish appear to have recently declined in three of four rivers, but size-structure indices demonstrated continued viability of the James River trophy fishery. -

Within Kthe United States, Kentucky’s native freshwater fish diversity is exceeded only by Alabama and Tennessee. This high diversity of native fishes corresponds to an abun- dance of water bodies and wide variety of aquatic habitats across the state – from swift upland streams to large sluggish rivers, oxbow lakes, and wetlands. Approximately 25 species are most frequently caught by anglers either for sport or food. Many of these species occur in streams and rivers statewide, while several are routinely stocked in public and private water bodies across the state, especially ponds and reservoirs. The largest proportion of Kentucky’s fish fauna (80%) includes darters, minnows, suckers, madtoms, smaller sunfishes, and other groups (e.g., lam- preys) that are rarely seen by most people.
