The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Means of Introduction: There is apparently disagreement concerning the native status of alewife in Lake Ontario. Miller (1957) and Smith (1970) point out the first record from Lake Ontario was in 1873. Smith (1970) is of the opinion that it was introduced into the lake. Although Smith (1970) brings up the possibility that alewife were introduced into Lake Ontario with American shad stockings in the 1880s, he discounts this possibility in favor of the hypothesis that they reached the lake via the Erie Canal from the Hudson River. He contends that alewife were only able to invade the lake after the decline of predators such as lake trout and Atlantic salmon in the 1860s. Other authors believe, this species was probably native to Lake Ontario (Lee et al. 1980 et seq.) and spread through the Great Lakes via the Welland Canal (Lee et al. 1980 et seq.). The species was first reported from Lake Erie in 1931, Lake Huron in 1933, Lake Michigan in 1949, and Lake Superior in 1954. The alewife was intentionally stocked in inland waters. The population in the New River, West Virginia, resulted from stockings in Claytor Lake, New River, Virginia (Jenkins and Burkhead 1994). The recently discovered population in Lake St. Catherine, Vermont, is likely a result of an illegal stocking (Good, personal communication). Lakes in the Adirondack Mountains and Otsego Lake, New York were illegally stocked with alewife for forage (Smith 1985; Sinnott, personal communication; D. Warner, personal communication).

Status: Established in many states and throughout the Great Lakes. Introduction to the Youghiogheny River was unsuccessful (Hendricks et al. 1979).

Impact of Introduction: Presence of the alewife could restructure a lake's food web, leaving less food for native species (USEPA 2008). Disappearance of native planktivorous salmonids, such as whitefish, in the Great Lakes has been attributed in part to the introduction of alewife, which reduced zooplankton populations (Crowder and Binkowski 1983; Todd 1986; Page and Laird 1993). Crowder (1984) speculated that a cisco native to Lake Michigan, the bloater Coregonus hoyi, evolved fewer and shorter gill rakers, and shifted to benthic habitat and diet as a result of competition with alewifes. Smith (1970) attributed the extermination of the lake herring and decline of chub species in the Great Lakes to the alewife. Smith also talks about the various interrelated changes that took place in each of the Great Lakes as alewife abundance increased. Christie (1972), on the other hand, argues that the alewife was not responsible for these changes. The alewife is the dominant fish in Lake Michigan. It accounts for 70–90% of the fish weight (Becker 1983). Alewife has recently become the dominant prey item for double-crested cormorants in Lake Champlain (DeBruyne et al. 2012). Additionally, alewife (both age-0 and adults) show significant spatial overlap with age-0 rainbow smelt (Osmerus mordax) in Lake Champlain, which could alter population dynamics of both species through competition (between age-0 alewife and smelt) or predation (by adult alewife on age-0 of both species) and limit the availability of these forage fish to larger predators such as lake trout (Salvelinus namaycush) and Atlantic salmon (Salmo salar) (Simonin et al. 2012). Pothoven et al. (2013) documented an increased abundance of age-0 yellow perch (Perca flavescens) and changes in the zooplankton community structure in Saginaw Bay, Lake Huron following the disappearance of alewife, including increased abundance of cladocerans (e.g., Daphnia spp., Bythotrephes, Leptodora) and decreased abundance of cyclopoid copepods. Alewife contain high levels of thiaminase, which reduces absorption and assimilation of thiamin in predators such as salmonids can cause reduced body condition, swim performance, and other potenial impacts (Houde et al. 2015)

Alewife is a very important species in the history of biological invasions in the Great Lakes. Periodic large-scale die-offs littered the beaches of the Great Lakes with rotting fish in the 1960's. Such die-offs can pose both a nuisance and a health hazard (Becker 1983). Prompted by calls for alewife management, Pacific salmonids were introduced to both control alewife populations and utilize alewife as a food source for sport fisheries.

Remarks: Although there is a report of two small alewives taken from the Colorado River, Texas (Bean 1882), we believe this record is in error. Bean (1882) reported that the specimens were sent to Professor Baird at the National Museum. However, a query of the museum's holdings did not return these specimens. We believe the fish are more likely either misidentified A. chrysochloris or A. sapidissima. Alosa sapidissima were stocked in the Colorado River in 1874 (Bean 1882).

Alewife is one of the most frequently found prey items in the diet of the Double-Crested Cormorant in the southern basin of Lake Michigan (Madura and Jones 2016).

Voucher specimens: Michigan (UMMZ 157215, 160969, 167872, 171308, 170945), Wisconsin (UMMZ 162861, 167945).
