| 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 Toyama Bay, southern Japan Sea. Samples were taken using two different mesh sizes (0.35mm and 0.06mm) and 10 l Van Dorn samplers during a series of monthly field observations from April 1995 through March 1996. The total number of adult copepods (0.35mm mesh net samples) peaked in March-May (spring) and in September-December (autumn). While the spring peak was mainly formed of a combination of a few cold-water (Oithona atlantica and Metridia pacifica) and eurythermic (probably Corycaeus affinis) species each with a high abundance, the autumn peak was composed of many warm-water species each with a lower abundance. The spring peak synchronized with the seasonal increase of both copepodids (0.06mm mesh net samples) and nauplii (10 l seawater samples) of Oithona spp. which formed a major constituent of the copepod assemblage. However, there were no autumn peaks of copepod nauplii. We suggested that the intensified reproduction in spring of oithonid copepods plays a significant role in the food availability for the first feeding anchovy larvae, depending on the phytoplankton bloom in Toyama Bay. | |||||||||||
