  abstract = {{A} 13-year biomonitoring survey was carried out on the {E}uropean eel, {A}nguilla anguilla for the first time in {N}orth {A}frica ({A}lgeria) where there is a serious lack of information on the species. {T}he study targeted specimens populating the only four sites where the species is both potentially present and legally exploited ({L}ake {O}ubeira, {L}ake {T}onga, {M}ellah lagoon and {M}afragh estuary). {A} total of 1370 individuals were sampled ranging from 17 to 113 cm in length, 19 to 2642 g in weight and 0.7 months to 6.6 years old, age being estimated from otolith growth marks. {O}tolith interpretation and age estimation were generally unambiguous at all four sites. {A}ccording to the {EELREP} silvering index, the highest proportion of silver females was captured in fresh water ( 46% in {L}ake {O}ubeira and 25% in {L}ake {T}onga), whereas a third were present in brackish water ({M}afragh and {M}ellah). {T}he sex ratio was in favour of females, and silver males were found to mature early (mean length 40 +/- 1 cm, mean weight 123 +/- 28 g and mean age 2 +/- 0.6 years). {G}rowth differed at the four sites, and the growth rate was highest in {L}ake {O}ubeira and asymptotic length highest in {M}ellah lagoon. {M}etamorphosis from the yellow resident stage to the silver migrating stage occurred very early in the eels' continental life ( between 3 and 4 years of age). {R}esults highlight rapid growth in these {A}lgerian sites, and earlier silvering than in eels living in {E}uropean waters, suggesting different life-history traits of {A}. anguilla in {N}orth {A}frican waters, influenced by environmental conditions.},
