Maturation and oviposition in the Japanese mitten crab Eriocheir japonicus (De Haan) in relation to their downstream migration
- Satoshi Kobayashi, S. Matsuura

Egg size, Duration of Incubation, and Larval Development of the Japanese Mantis Shrimp in the Laboratory*1
- T. Hamano, S. Matsuura
- Biology, Environmental Science
- 2007
The egg size, the duration of incubation, and the larval development of the Japanese mantis shrimp are described and the relationship between theduration of egg incubation and water temperature was studied for the first time in Stomatopoda.
Ovarian structure and batch fecundity in Lophiomus setigerus
- M. Yoneda, M. Tokimura, S. Matsuura
- Biology, Environmental Science
- 1998
The results suggested an extended spawning season during which females undergo repeated spawnings of anglerfish Lophiomus setigerus, and when the most advanced oocytes attained the secondary yolk stage, they formed a batch that separated from the adjacent group of smaller oocytes.

Lunar spawning in Siganus canaliculatus
- M. M. Hoque, A. Takemura, M. Matsuyama, S. Matsuura, K. Takano
- Biology
- 1 December 1999
The gonadosomatic index (I G ) and serum vitellogenin (VTG) levels fluctuated according to the lunar cycle; I G and VTG levels showed peaks at around the new moon and the waning moon, respectively, suggesting that spawning of this species is synchronized with the lunar cycles.
Testicular development and serum levels of gonadal steroids during the annual reproductive cycle of captive Japanese sardine
- M. Matsuyama, S. Adachi, Y. Nagahama, C. Kitajima, S. Matsuura
- Environmental Science, Biology
- 28 February 1991
The pattern of seasonal changes in the gonadosomatic index (GSI) was inversely correlated with that of water temperature, and reflected the degree of testicular maturity in the Japanese sardine, and steroidal regulation of spermatogenesis and spermiation in other teleosts.
Laboratory Studies on Molting and Growth of the Shore Crab, Hemigrapsus sanguineus de Haan, Parasitized by a Rhizocephalan Barnacle.
- T. Takahashi, S. Matsuura
- BiologyThe Biological Bulletin
- 1 June 1994
The annual growth of parasitized males and females was about half that of unparasitized crabs, and the life-span of the externa and the molting of the host would seem to be closely connected.
