[EN] Ratios and equations between the wet fin weight and the body weights or size of the blue shark (Prionace glauca) were recorded from 768 observations carried out in two processing plants using landings of fresh specimens of this species with their fins attached. The mean ratios obtained between...

description [EN] Ratios and equations between the wet fin weight and the body weights or size of the blue shark (Prionace glauca) were recorded from 768 observations carried out in two processing plants using landings of fresh specimens of this species with their fins attached. The mean ratios obtained between the complete set of wet fins and bodies were 5.88%, 7.33% y 14.16% for round weight, gutted weight and dressed weight, respectively. The whole caudal fin accounted for the largest proportion of the total weight of the fin set (44%), followed by the pectoral fins (35%),the first dorsal fin (9%), the pelvic fins (7%),while the anal fin and the second dorsal fin each represent approximately 2% of the total weight. The results were very similar to the findings of other studies conducted on board the pelagic longline vessels of the European fleet. Highly significant linear relationships were obtained between fin weight and body weight or size.

Les ratios moyens obtenus entre le jeu complet d’ailerons mouillés et de corps représentaient 5,88%, 7,33% et 14,16% pour le poids vif, le poids éviscéré et le poids manipulé, respectivement. La nageoire caudale entière représentait la plus grande proportion du poids total du jeu d’ailerons (44%), suivie des nageoires pectorales (35%), de la première nageoire dorsale (9%), des nageoires pelviennes (7%), tandis que la nageoire anale et la deuxième nageoire dorsale représentent approximativement 2% du poids total. Les résultats étaient très similaires à ceux d’autres études menées à bord de la flottille européenne de palangriers pélagiques. Des relations linéaires très significatives ont été obtenues entre le poids des ailerons et le poids corporel ou la taille.[ES] Ratios y ecuaciones entre el peso húmedo de las aletas, el peso de los cuerpos y la talla a la horquilla de la tintorera (Prionace glauca) fueron obtenidos a partir de 768 observaciones realizadas en dos plantas comercializadoras aprovechando los desembarcos en fresco de ejemplares de esta especie con sus aletas adheridas. Los ratios medios obtenidos entre el set completo de aletas húmedas y los cuerpos fueron de 5,88%, 7,33% y 14,16% para el peso vivo, peso eviscerado y peso canal, respectivamente. La aleta caudal completa representó la mayor aportación al peso total del set de aletas (44%), seguida de las pectorales (35%), la primera dorsal (9%), las pélvicas (7%), mientras que la anal y la segunda dorsal representaron aproximadamente el 2% cada una de ellas. Los resultados son muy similares a los obtenidos en otros estudios realizados a bordo de la flota europea de palangre pelágico. Las relaciones lineales obtenidas entre el peso de las aletas y el peso de los cuerpos, o su talla, fueron altamente significativas.The authors would like to thank the employees of SILVAFRESH, PESCASILVA, PROPEGAL PESCALUJO for their help in the data collection, without whose efforts this paper would not have been possible.
