Abstract
    The harpacticoid fauna of a sandy sediment in the Sluice Dock of Ostend, Belgium, was dominated by a single species, Canuella perplexa, that attained an average annual density of over 400 ind. 10 cm-2 in 1976 and 1977, whereas other species had a total mean density of less than 10 ind. 10 cm-2. In the summer of 1979 a dystrophic crisis with abundant growth of Ulva occurred and in March 1980 the lagoon was drained. After refilling of the lagoon, the sediment was immediately colonized by good swimming harpacticoids, that attained densities of 200 ind. 10 cm-2. Three months after refilling Canuella perplexa reappeared and the system returned to its original state within one month.
