説明

Barnacles have been recognized as fouling organisms for a long time. Adhering to ship hulls, piers, wharves and cooling-water pipes of power stations, they cause significant industrial damage. Nonetheless, barnacle nauplius larvae constitute a significant food source for the larvae and juveniles of various animal species in the coastal ecosystem. In order to evaluate the contribution of fouling barnacles to this larval output, every two weeks in 2008, the author examined the number of brooded eggs of barnacles settled on a test plate hung in the water in the Hyogo Canal, Kobe. Measurements of sea water temperature and salinity at the observation site, the density of barnacle nauplii in the plankton, and the number of settled barnacles on the test plate were made. The number of nauplius larvae hatched from the barnacles settled on the test plate was thereby estimated to be 100,000/cm2 over the whole year.
