Description

Standing crops of 9 species of macroalgae (Phaeophyta), 2 species of seagrasses, 4 species of sea urchins, and the spiny top shell was investigated at depths of 2, 5, 10, 15, and 20m along 23 transects on the coasts from west of Tappi to Fujishima, Tsugaru Peninsula, Aomori Prefecture on August 2-6, 1985. Characteristic differences were observed in their vertical distributions be-tween the Japan Sea coast and the Tsugaru Channel coast with Tappi Point as the border. The vertical distribution of standing crops of the spiny top shell and the sea urchin Strongylocentrotus nudus was quite similar to that of Ecklonia stolonifera and Laminaria japonica, respectively. These results suggest that the two species of seaweed, whether for food or habitat, are favored by sea animals.
