Abstract: European eel, Anguilla
anguilla L., has a wide distribution from polar to arid climates. The growth
and sex in eels from the River Asi, which is in the most arid region of the
species distribution, and at a temperature of 21-27 ºC close to the
experimentally determined optimum for the eel were examined. A total of 315
European eels were collected between January 1997 –May 1998 and April 2003.
Growth was fast, with a high asymptotic length. Temperature is the main factor
driving to growth; apparently, growth does not cease during the hot, arid
summer. Since these fastest growing stocks will be of major significance for
overall dynamics of the whole population, further studies of these southern
eels will be required.
Key words: Anguilla anguilla, Asi
