| 内容記述 | The recently discovered freshwater eel species of the Luzon mottled eel, Anguilla luzonensis, has only been found in very limited area at the tip of the Northern Philippines. Here we investigated the early life history of A. luzonensis for the first time to help understand its larval dispersal pattern in the western North Pacific, and compared it to A. celebesensis and data from previous studies. Genetically-identified glass eels of A. luzonensis collected from the northern Luzon Island in January and February 2009 (n=3 and 8, respectively) were used to study the age of recruitment of this species using otolith microstructure. The leptocephalus stage was 129.6±10.7 days (mean±s. d.; range, 113 to 146), followed by 18.4±3.7 days (13 to 25) at the metamorphosing and 17.6±5.1 days (7 to 23) at the glass eel stages. These specimens were found to be hatched between August and September 2008. A previous study on a small number of the leptocephali of A. luzonensis collected offshore reported that the hatching dates were between February and March, and thus the spawning season of A. luzonensis is suggested to span at least a half of a year. | |||||
