Size-mass relationships were estimated for 4 species belonging to genus Semisulcospira from the Guem River, Korea. These 4 freshwater snail species: Semisulcospira libertina, Semisulcospira coreana, Semisulcospira gottschei, and Semisulcospira forticosta. Between June and November 2011, samples were caught by dredge (mesh size 10mm of multifilament nylon, total length 4.35 m) at depths of < 2 m. Estimates of for parameter b of the size-mass relationship (W = aSHb) ranged between 2.0072 (Semisulcospira libertina) and 2.3463 (Semisulcospira gottschei).
