As a nutrition source in either japanese and Western international locations, the eel is a vital fish. through the years, extraordinary development has been completed in figuring out the mysterious existence cycle of eels that has interested scientists because the age of Aristotle. The spawning zone of the japanese eel was once found and the migratory course of its larvae was once elucidated. With the advance of innovations for man made induction of gonadal maturation, it grew to become attainable to procure hatched larvae. Larval rearing to the leptocephalus degree, some of the most tricky initiatives serious about eel tradition, ultimately used to be completed. via providing those very important breakthroughs, Eel Biology should be of serious assist in the advance of potent administration options for keeping good eel populations. With contributions by means of best specialists, this ebook is a invaluable resource for researchers in addition to technicians within the fields of aquatic biology, aquaculture, and fisheries.

2001) or introgression (see Smith 1992) that could cause such findings. Aoyama based on the only morphological key for the anguillid eels is apparently insufficient (see the chapter by S. Watanabe, this volume), or that there are some cryptic species that are only genetically distinguishable (Aoyama et al. 2000). For example, Lin et al. (2001) obtained A. borneensis (malgumora) from Luzon Island in the Philippines, which is a location far from its species range where the species has never been found previously (Ege 1939; Inger and Kong 1962), and Aoyama et al.

Two different dispersal routes from the Indo-Pacific to the Atlantic. The star indicates the place of origin, and the areas covered by gray show the present distribution of the anguillid eels in the Indo-Pacific.
