在日本琉球群岛冲绳沿岸的两条溪流中，对日本石首鱼的产卵场所进行了调查。结果表明，在25个产卵点和52个产卵点中，尽管偶尔暴露于海风中，但盐度始终在2‰以下。这些地点的pH值在7.7-10.2之间，从未降到酸性范围内。尽管两条溪流的最大水深和溪流宽度等地形特征存在显著差异，但两条溪流产卵点的水深和离岸边的距离均无显著差异。
Oviposition sites of Buergeria japonica were surveyed in portions of two streams near the coast on Okinawa Island, Ryukyu Archipelago, Japan. Twenty-five and 52 oviposition sites were found. At all these sites the salinity was constantly 2‰ or less despite occasional exposure of these portions to the sea breeze. The pH value at the sites, ranging from 7.7-10.2, never dropped into the acid range. There were no significant differences in water depth or distance from the bank at the oviposition sites between the two streams, despite the prominent differences in some topographic characters, such as maximum water depth and stream width.
