Reproductive biology and impacts on aquatic species

Three specimens of short finned eel, 70.5-81.0mm in total length, were found in the samples collected in Nagata River, Shimonoseki, Japan, on July 9, 1974. They have a total vertebral count of 114-117, predorsal 36 and 38, preanal 37 and 39, ano-dorsal 0 and 1, abdominal 44 and 45, and caudal 69 and 72, being easily distinguishable from the other specimens. Closer examination of this exotic eel revealed that they are tentatively referable to Anguilla australis RICHARDSON, which is known only from the southern hemisphere. These youngs are considered to be derivatives from the imported elvers for eel culture.
