Estudio de la celularidad en las diferentes regiones musculares de rodaballos diploides y triploides, Scophthalmus maximus L.

Abstract

Se analizó la celularidad muscular en cuatro zonas del miotomo: epiaxial superior, hipoaxial superior, epiaxial interior e hipoaxial inlerior, en2 grupos de rodaballos: 7 diploides y 7 triploides. En diploides, las zonas epiaxiales (superior e interior) mostraron mayores valores del tamaOO (p0,05) que las hipoaxiales, siendo tales valores mayores en hembras que en machos. En triploides, ~ distribución librilar mostró algunas dilerencias respecto a diploides, observándose mayores valores del tamaño librilar en las regiones epie hipoaxiales de la zona superior del pez, mientras que el menor número y densidad de fibras fue encontrado en la región epiaxial superior. En relación al sexo, el tamaño librilar lue menor en hembras que en machos triploides, mientras que el resto de parámetros musculares mostraron generalmente mayores valores en hembras. Al comparar ambos grupos, la hipertrofia librilar fue mayor en triploides (P<0,05), en todas las zonas musculares (1-4).

The muscle cellularily was analyzed in lour regions (epaxial upper. hipoaxial upper, epaxial bottom and hipoaxial bottom) en two populatioos ~ turbo!: 7 diploid and 7 triploid specimens. Diploid specimens showed higher values 01the size and number 01 whije fibres in the epaxial!han in!he hipoaxial zones, being such values higher in lemales than in males. In triploid specimens, the highest values olthe muscle fibres size were 100M!! !he upper zones (epaxial and hipoaxial), whereas!he lowest number and densijy 01libres was lound in !he epaxial upper zone. In relationtothesex influence in triploid, the lowest value 01Ihe muscle fibres size was lound in lemaJes, whereas Ihe rest 01 muscle parameters were higher in lemaIes. When comparing bolh groups, muscle hypertrophy was higherin triploid than in diploid specimens (P<0,05), in all the muscle zones (1-4).
