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.

Apeltes quadracus (Mitchill, 1815)

Common name: Fourspine Stickleback

Taxonomy: available through www.itis.govITIS logo

Identification: Fourspine stickleback has a bony ridge on each side of the abdomen, making it triangular in cross section, with flat belly and sharp back; it is fusiform in side view, tapering to a pointed nose and to a slim caudal peduncle; there are two to four free dorsal spines standing close one behind the other, inclining alternately to one side or the other; another spine is attached to the dorsal fin by the fin membrane; the anal fin is similarly preceded by an attached spine, and each ventral fin is represented by a stouter curved spine, strongly saw-edged, followed by about two slender rays; the dorsal fin stands over the anal as in the nine-spined species, but both these fins are more rounded in outline, while the caudal fin is relatively longer and narrower than in any of our other stickleback species. Scott and Crossman (1973); Smith (1985); Robins et al. (1986); Page and Burr (1991).

Size: 6.4 cm

Native Range: Europe and Atlantic coast of North America. Atlantic Slope from Gulf of St. Lawrence to Trent River system, North Carolina. Mostly a nearshore marine species, but far inland populations occur in lakes in Nova Scotia, and in Hudson, Delaware, and Susquehanna River drainages (Page and Burr 1991).

Ecology: The Fourspine Stickleback can be found in fresh and brackish water from 0 to 3 m deep. Adults inhabit weedy bays and backwaters (Delbeek and Williams, 1988).

Apeltes quadracus often live sympatrically with other species of stickleback throughout their native range, though they are generally solitary with regard to other members of their own species. Individuals are often observed perched among bottom debris and vegetation, never in open water, hovering over a patch of substrate, picking at it frequently, then moving on to another patch (Delbeek and Williams 1987). Delbeek and Williams (1987) also found that fourspine stickleback fed exclusively on the bottom, wither among benthic vegetation or from the substrate, the most abundant organisms in their diets being diatoms, nauplii, nematodes, ostracods, and cyclopods. During spawning, the males of this species establish territories and build small nests in which females lay their eggs (Courtenay 1985). Them male then chases the female away and cares for the eggs until they hatch. Courtenay (1985) also found that, unlike other stickleback species, male Apeltes tend multiple nests at one time in both laboratory and natural breeding site observations. Fourspine stickleback also has the widest range of salinity tolerance of any North American species of stickleback (Holm and Hamilton 1988).

Means of Introduction: Shipping, Ballast Water (USEPA 2008). Denoncourt et al. (1975) were uncertain if the Susquehanna populations of this species, and that of several other additions to the drainage, represented natural occurrences or were the result of accidental introductions.

Bait shops in Alabama were found to be selling stickleback mixed in with fathead minnows at the time the specimens were collected (N. Nichols, pers. comm.).

Status: Present status in Alabama and New Jersey is unknown. Apparently established in Pennsylvania. Has become the dominant species in nearshore areas of Mission Marsh, Thunder Bay, Ontario (Stephenson and Momot 2000).

Impact of Introduction: Confined to coasts. Rapid increases of Apeltes in Thunder Bay suggests the species is displacing native stickleback species at a rapid rate (Stephenson and Momot 2000).

Remarks: In 1986, an introduced population was discovered on the Canadian side of Lake Superior in Thunder Bay; the suggested means of introduction in that case was ballast water (Holm and Hamilton 1988). In 1995, Apeltes were also taken from the Black and Nipigon Rivers (Stephenson and Momot 2000).
