  • An Analysis of the Diets of Four Spatially Overlapping Damselfishes of the Genus <I>Chromis</I>

抄録

The diets of four planktivorous damselfishes of the genus Chromis from Miyake-jima, Izu Islands, were compared.Copepods, principally of the genera Pleuromamma, Euchaeta, Scolecithrix, and Eucalanus, plus larvaceans, were the predominant dietary items.There were no significant differences between damselfish species regarding the type of copepods consumed at the generic level.Also, it does not appear that the damelfishes selected different sized food items.However, one species, Chromis flavomaculata, appears distinct from its three congeners, C.albomaculata, C.analis, and C.chrysura, in having a diet containing significantly more copepods and fewer larvaceans.
