The fresh water species Green Swordtail Xiphophorus heller Heckel, 1848, endemic to central and northern America, was introduced to Japanese waters in the 1960's, established populations being recorded on Kume-jima island and Okinawa-jima island (Okinawa Prefecture), and in Yamanashi Prefecture. A single specimen (39.9 mm SL) of Green Swordtail, collected from the Handa River in May 2011, was the first record of the species from Amami-oshima island (one of the Satsunan Islands). Although the population increased hugely over the following years, it decreased significantly in winter 2015/2016, during which record low temperature levels occurred, only to recover within six months. The morphology of specimens from Amami-oshima island are described in detail, and distributional records of the species and recent population status on Amami-oshima island are discussed.

We conducted a series of survey to find the source of difference in preferences among the U.S.A., Germany and Japan through the relationship between food preferences, dietary habits and evaluation on beer taste. We tried to find a measure to seize food preferences and dietary habits by questionnaires and we unveiled, by beverage preference survey, the degree of importance of factors in consumers' minds concerning both functions of beer in daily life and factors which compose deliciousness of beer. The relationship between drinking occasion and taste of beer was analyzed by the evaluation of taste of beer from the result of a test drinking using the same samples across the three countries. We recognized that there were clear differences among the three countries in food preferences, dietary habits, images toward beer, evaluation on preference and flavor strength of beer after the test drinking. It was made clear that the origin of regional difference in the taste of beer was related to the differences in food preferences, dietary habits and functions that consumers desired.

The longitudinal distribution of Ryukyu-ayu Plecoglossus altivelis ryukyuensis in the Katoku River, a small stream on Amami-oshima Island, southern Japan, was observed from December 2003 to November 2004. The number of Ryukyu-ayu in pools was greater than in glides or riffles in each life history season [spawning (Nov. to Feb.), up stream migration (Mar. to May) and growth (Jun. to Oct.) seasons], an analysis by Spearman’s correlation coefficient by rank test indicating that such abundance in pools tended to be consistently greater in lower reaches. This suggests that large pools in lower reaches are an important habitat for Ryukyu-ayu in the Katoku River. Accordingly, for the future conservation of the lower reaches and creation of large pools may be a positive step of this endangered fish.
