TY - JOUR T1 - Décalage de la période de reproduction par raccourcissement des cycles photopériodique et thermique chez des poissons marins A1 - Girin,Michel A1 - Devauchelle,Nicole UR - https://archimer.ifremer.fr/doc/00000/5229/ KW - Histoire Ifremer N2 - Sea bass (Dicentrarchus labrax), turbot (Scophthalmus maximus) and gilthead sea bream (Sparus aurata) spawners were kept in 2 identical 40 m3 tanks, one outdoors (control) and one indoors (test) during a 5-year experiment. The control tank was under natural yearly photoperiod and the temperature cycles of western Brittany. The test tank was under similar variation for 3 years but with the cycles compressed into 10 months. The 3 species spawned naturally in these artificial conditions at various stages of the experiment. After 3 years, the fish in the test tank spawned an average 5 months ahead of the others.
