Definition of Term

fin element counts
(English) In preserved fishes, it is often necessary to spread the fins by gently flexing the body or by lifting these elements, sometimes one by one, with a probe or a needle. Magnification is often required for accurate counts. In many publications, counts of spines are given in Roman numerals, to distinguish them from the soft rays (e.g., XIII, 21-25). (See also: fin rays, spine, soft ray)
nombre de rayons des nageoires
(French) Dans les poissons conservés, il est souvent nécessaire d'étaler les nageoires en fléchissant doucement le corps ou en soulevant ces éléments, quelquefois un par un, avec une sonde ou une aiguille. Un agrandissement est souvent nécessaire pour l'exactitude des dénombrements. Dans beaucoup de publications, les nombres de rayons osseux sont donnés en chiffres romains, pour les distinguer des rayons mous (par exemple, XIII, 21-25). (See also: fin rays, spine, soft ray)
