| Abstract | ||
| This paper presents a comparative study of the energy reserves of two populations of eels Anguilla anguilla (L.1758) fished in the El Mellah Lagoon and Lake Tonga in northeastern Algeria. Results of the demographic structure of the population showed that the yellow eels predominated numerically in both plans of water. The monthly follow up of the (Kc) condition factor recorded no significant difference in the values of this index between the two stations. Compared to the extraction of metabolites, the protein content showed a significant increase at the end of autumn, which tended to decrease in winter. In addition, a significant increase was detected in the level of muscle lipids between the months, with higher levels observed in eels from El Mellah Lagoon. Hence, the eels fished at the site level proved to be particularly sensitive to Spatio-temporal fluctuations in environmental factors. | ||
