Abstract

15011989290320100119892163682309198812121988¬© IFREMER-Gauthier-Villars, 19891989IFREMER-Gauthier-VillarsThe skeletochronological analysis of pectoral spiny rays in the silurid Arius proops, collected during the "little summer of March", confirms the presence of a slow growth period during March and April in the rivers of French Guyana. Moreover, this study shows that the longevity of the species is short, 3 and a half years for the females and 3 years for the males, while their growth rate is relatively high, especially during the first half of their life. L'analyse squelettochronologique des rayons épineux pectoraux du silure Arius proops, capturé pendant le ¬´ petit été de mars ¬ª, confirme la présence d'une période de croissance ralentie de mars à avril dans les rivières de la Guyane française. L'étude montre que la longévité chez cette espèce est courte, 3 années et demie pour les femelles et 3 années pour les mâles ; en outre, le taux de croissance est assez élevé, surtout durant la première moitié de la vie des poissons. %U http://dx.doi.org/10.1051/alr:1989007 %@ 1765-2952 %[ 1989
