| 内容記述 | This paper describes the seasonal variations in abundance and species composition of the copepod assemblage as a food source for larval anchovy (Engraulis japonicus) in western Wakasa Bay, southern Japan Sea. Samples were taken 1-3 times a month from May 1995 through April 1996 using NORPAC nets and 10 l Van Dorn samplers. The total number of copepods (adults and copepodids) peaked in March-May (spring) and September (autumn). While the spring peak was mainly formed of a few temperate species (mostly Calanus sinicus and Corycaeus affinis), the autumn peak was characterized by many temperate-subtropical species such as Eucalanus attenuatus, Oncaea venusta and Centropages furcatus etc. The spring peak is considered to provide a food source for reproduction success of anchovy, and subsequently anchovy larvae showed a seasonal peak in abundance from June through July. We suggest that the food availability for spring larval anchovy depends on the naupliar abundance of several copepod species (Calanus sinicus, Corycaeus affinis, Oithona spp., Ctenocalanus vanus and Acartia omorii) of which their egg production is closely associated with the spring phytoplankton bloom. | |||||||||||
