| With the constant rising of the human population, it is essential to assess and manage the exploitation of the marine species for human consumption such as the anchovy of Bay of Biscay. Thanks to the PELGAS annual surveys, stocks of each species are estimated (biomass, repartition) and studies are undertaken to improve our knowledge about these species. Allozymic studies realized on the anchovy allowed to find a correlation between 2 alleles of the locus IDH and the habitat (depth). This allozyme has a key role in Krebs’ cycle,being speed limiting.. It enables to tolerate variations of temperature and dissolved oxygen. It would be interesting to do new research on variations in the anchovy’s environment and its migrations. |
