  abstract = {{A}ge and total length ({L}-{T}) data from a 11 year monitoring of the {A}nguilla anguilla eel population of the {C}amargue lagoons ({R}hone delta, southern {F}rance) were collected for glass, yellow and silver eels. {T}hree distinct models were calibrated to describe the growth process of undifferentiated eels, females and males, respectively. {U}ncertainty of parameter estimates was evaluated by bootstrapping. {F}emales were characterized by larger asymptotic body size ({L}-{T}) than males (580 +/- 50 v. 388 +/- 13 mm) and faster growth, whilst the {B}rody growth coefficient was larger for males than for females (means +/- {S}. {D}. 3.00 10(-3) +/- 1.68 10(-3) v. 1.73 10(-3) +/- 0.50 10(-3)). {S}exual differentiation was estimated to begin at 204 +/- 38 mm mean +/- {S}. {D}., i.e. at the end of the second year in the lagoons, well before the {LT} at which macroscopic differentiation became possible (c. 300 mm). {M}ales probably leave the lagoon or die (due to either natural or fishing mortality) within the first 3 years, whilst females can remain up to 5 years. {S}exual differentiation and maturation have a major role in shaping the {LT} structure of the population. {T}he {LT} and mass ({M}) data were fitted by allometric curves ({M} = a({LT})(b)). {T}he calibration of distinct curves for data from different years indicated that the allometric coefficient a was subject to wider interannual fluctuations than the allometric exponent b. {A} negative correlation linked the average {LT} and the allometric exponent (r = 0.58, {P} < 0 01).
