Since 1986 high mortality of hatchery-reared sea bass (Lates calcarifer) larvae appeared in Ifremer's Pacific Oceanological Center (Tahiti). Light and electron microscopy show vacuolation and cells with cytoplasmic inclusion bodies in the brain, spinal cord and retina. Numerous non-enveloped particles identified as viral units, icosahedral in morphology and measuring about 25 nm in diameter were found in the cytoplasm of the degenerating cells. The brain and the retina degeneration seem to be the cause of the high mortalities of hatchery-reared sea bass larvae.
