• The maximum catch of the "Maiwashi" in Tokyo Bay was seen from March to December, where the range of water temperature was 12-26°C and that of chlorinity was 16.0-19.2‰ Here the environmental condition from August to December in the year of 1947 and 1948 were analysed referring to the catch of the sardine. The haul varies according to the mixing ratio of the oceanic water to the coastal water, that is, where the salinity is high the haul is much. (Cf. Fig. 2 and Fig. 3) The main hauling grounds are the station from No, 3 to No, 8 in Fig 4 These grounds are rich in plankton (Cf Fig 6) and are boundary region of the water oceanic and coastal.
