KASUS INFEKSI IRIDOVIRUS PADA BENIH IKAN KERAPU PASIR, Epinephelus corallicola DI HATCHERY
Abstract: Seeding effort of
coral grouper fish, Epinephelus corallicola in Research Institute for
Mariculture (RIM) Gondol, Bali has been blazed the way, but rearing seed still
found constraint as height of mortality. One of death cause of seed is by virus
infection disease. An attempt for diagnosis iridovirus infection at seed coral
grouper Fish age sand around 60 days shows symptom as no eating, populating in
basin base, colour turn darken, and here in after death. Disease detection of
the showing symptom seed that has not generated death is observed based on
pathological anatomy and viral detection with PCR-probe. Disease detection also
conducted to seed after showing symptom and generated high death. Detection
based on pathological anatomy result many "giant cells" from spleen
organ. Disease detection based on PCR-probe of seed which has not died yield
thin positive band of iridovirus, while observation of death seed yields high
crystal clear positive band of iridovirus at 570bp.
