Species Identification and Ecological Study of the Genus Palaemonetes (Decapoda: Caridea) in the French Mediterranean

摘要: The distribution of the prawn species belonging to genus Palaemonetes is not well defined in Mediterranean, especially south France where controversy exists concerning taxonomic identification at level. A molecular diagnostic technique allowed us determine without any doubt presence varians Camargue. These basic results undertake ecological study species, which took place context a massive 100-year flood during winter 1993/94, leading rapid and major fall salinity that remained low until 1997, before increasing. impacts on catch life history traits lagoon were investigated from 1993 1999. There was positive correlation between catches salinity. Although we observed decline recruitment years 1994, reproduction parameters growth did seem be affected by comparative various Mediterranean northern environments populations also conducted.
