Yellow & Slough Sandshells (Lampsilis teres)


Overview

Overview

Yellow sandshell (Lampsilis teres anodontoides) and slough sandshell (Lampsilis teres teres) are subspecies of Lampsilis teres which is listed as Endangered in Wisconsin. They are found in large rivers in the western part of the state. The yellow sandshell occurs in swift currents in clean swept sandy areas in the main channel. Eight fish species have been recorded as its host, including gars, basses, sturgeon and centrarchid species. The slough sandshell occurs in muddy areas adjacent to the current of large rivers. Three fish species have been recorded as its host, including gar species.

Species guidance


Note: a species guidance document is not available at this time. Information below was compiled from publication PUB-ER-085-99 (now out-of-print).

Identification: The smooth, shining yellow shell is usually weakly rayed with green. The beak region is often reddish or brown. It is thick, elongated and somewhat inflated. The anterior end is rounded and the posterior end is pointed. The dorsal and ventral margins are straight and nearly parallel. Lateral teeth are long, roughened and nearly straight. Pseudocardinal teeth somewhat compressed and serrated. Nacre is white and may be tinged with salmon color, iridescent posteriorly. The female is more rounded and inflated than the male, and has an orange stripe on inner surface. Length up to 6 inches (150 mm) long. In contrast to L.t.anodontoides, the young are yellowish with few rays.

Habitat: Inhabits large, swift rivers with a sandy bottom and in water a meter or more in depth.

State Distribution: Occurs in the Mississippi, Namekagon, and lower Wisconsin Rivers.

Phenology: Yellow sandshells are winter breeders. Glochidia of this subspecies has been found on long-nosed gar (Lepisosteus osseus),blue-spotted sunfish (Lepomis cyanellus), orange-spotted sunfish (L. humilis), large-mouth bass (Micropterus salmoides), white crappie (Pomoxis annularis), and black crappie (P. sparoides).

Management Guidelines: Habitat destruction and river pollution have resulted in mussel declines. Protection of habitat and improvements in water quality along with restriction of dredging, impoundments, sand and gravel mining, and navigational improvements would benefit this species
