Calanoid copepod eggs in sea-bottom muds. II. Seasonal cycles of abundance in the populations of several species of copepods and their eggs in the Inland Sea of Japan

摘要: The seasonal cycles of abundance populations dominant calanoid copepods in the water column and their eggs recovered from bottom sediment central part Inland Sea Japan are described. numbers both fluctuated markedly with season an essentially similar pattern among 6 species studied (Tortanus forcipatus Giesbrecht, Calanopia thompsoni A. Scott, Acartia erythraea clausi Centropages abdominalis Sato, C. yamadai Mori). density sea was highest shortly before population adults late copepodids disappeared plankton; then gradually decreased until appearance next planktonic population.
