Abstract
To restore diversity and ensure sustainability of coastal ecosystems, it is important that the appropriate habitat is designed for all the life stages of species inhabiting those ecosystems. This study aimed to classify coastal fish species in Tokyo Bay on the basis of their habitat use patterns. A bibliographic survey was performed and the fishes were categorized into six types (freshwater, mud flat, sand beach, rock shore, deep sea, and open sea). Further, the association between reproduction and habitat use pattern was analyzed. Thirty-six fish species were categorized into 17 types on the basis of their habitat use pattern. The number of habitat types utilized by individual species during their life cycle ranged 1-6. The mud flat habitat was particularly important for many coastal fishes.
In terms of reproduction, the proactive establishment of microtopographic environments that support fish survival is a key priority, particularly for single habitat type users, whereas spatial networks are necessary for species that use multiple habitat types.
