Abstract
Disease occurrence and dead cell ratio of Porphyra cultivated at Seocheon area were studied. Seaweed samples were collected monthly at 12 cultivating sites of Porphyra from Nov. 2008 to Mar. 2009. Although disease occurrence was low at the beginning of cultivation at the most of collecting sites, the occurrence increased with time. The most common symptom of Porphyra disease in this area was diatom attachment, followed by white rot disease. Licmophora sp. was the most common species of diatom and its attachment was the highest on November, the beginning of cultivation. Although the occurrence ratios of green spot disease and white rot disease were high on November, chytrid disease was increased at the end of cultivation period. Dead cell ratio of Porphyra thalli was different at each study site and cultivating time, but normally the ratio was high at the end of cultivating season. The changes of dead cell ratio could be related to the nutrition supplement and currents, and the more precise reason of dead cell ratio would be revealed by further research related to cultivating environment conditions.
