A landscaped community dominated by large plants (seaweeds and seagrasses) that inhabit the intertidal to subtidal zones of the sea is called a "seagrass bed". Among seaweed beds, those dominated by seed plants (such as eelgrass) are called "eelgrass beds". Eelgrass beds are inhabited by a wide variety of animals, and their abundance is large. Each animal species uses eelgrass beds for various purposes such as habitat, feeding, shelter, and spawning grounds, resulting in complex interactions among species.
In this practice, eelgrass bed animals will be sampled in the eelgrass beds of Lake Akkeshi and Akkeshi Bay, which have different environments, using the same method. By measuring and comparing their biomass and species diversity, we will understand how the eelgrass bed communities are formed and how they fluctuate.
