内容記述タイプ Abstract
内容記述 The habitats used by leptocephali are poorly known except for a few studies on their depth distributions or collections of recruiting leptocephali in some areas. Leptocephali have been reported to be collected by light traps in tropical coastal habitats, but their species composition or development stages have not been clarified. We report the collection of small numbers leptocephali in light traps set within and adjacent to coral reef habitats along the west coast of Ishigaki Island of the Ryukyu Island chain of Japan. Four muraenid and one ophichthid leptocephali at the early-metamorphosis stage were collected at the outer reef edge in May and June of 2007 and 2008. Two pre-metamorphosis stage Muraenesox cinereus leptocephali were collected between the inner and outer coral reefs in August 2006. Visible gut contents in the muraenesoscid larvae suggested they were feeding near the reefs. These collections clarify that both metamorphosing and pre-metamorphosing leptocephali can be caught in light traps, but it remains questionable if light traps effectively sample for leptocephali in near-shore habitats. Future research needs to evaluate the degree to which light traps can collect leptocephali by comparing their catches to other evidence about the presence of leptocephali in the same habitats at night.
