抄録

The gobioid fish, Boleophthalmus chinensis (OSBECK) is narrowly distributed to the inner part of Ariake Sound and a part of Yatsushiro Sea in Japan. The authors transplanted 31 inmature individuals of this fish from the inner part of Ariake Sound to the estuary of River Tatara, Fukuoka City (Text-Fig. 1; Pl. ⅩⅨ, Figs. 1, 2). These transplanteds were 64~88 mm in total length and 1.7~6.0 g. in body weight of one year old (Table 1; Pl. ⅩⅨ, Fig. 3). 3 years after this transplantation it was found that over 10 individuals of the transplanted survivied in the new habitat. 4 years after the transplantation 2 of the survivors were recaptured with bamboo-traps (Text-Fig. 2). One of these collected specimens was 176 mm in total length and 48.0 g. in body weight, and the another was 182 mm and 50.7 g. (Table 2; Pl. ⅩⅨ, Fig. 4). From the result of this transplantation-experiment, ecology and life history of this gobioid fish the authors analysed the factors that were essential for the fish to reproduce in a new habitat where transplanted (Pl. ⅩⅩ; Pl. ⅩⅨ; Text-Figs. 2, 4).
