The aim of this project is to identify new biomarker for the evaluation of the health status of sharks caught in the Adriatic Sea and their susceptibility to environmental changes. To reach this objective, melanomacrophages have been used as stress biomarkers on these organisms, since they are already widely used in teleosts, amphibians and reptiles. In this study, hepatic melanomacrophages have been evaluated in four species of sharks caught in the Adriatic Sea, both from a morphological and quantitative point of view, evaluating differences among species, sexes and, where possible, between these and the reproductive period. In conclusion, it has been assessed if there was any significant correlation between melanomacrophages and age of smooth-hound males.
Lo scopo di questo progetto consiste nell’andare ad identificare nuovi biomarker per la valutazione dello stato di salute degli squali pescati in Adriatico e la loro suscettibilità ai cambiamenti ambientali. Per raggiungere questo obiettivo si è andati ad utilizzare i melanomacrofagi come biomarker di stress, già ampiamente utilizzati in teleostei, anfibi e rettili, in questi organismi. In questo studio sono stati valutati i melanomacrofagi epatici in quattro specie di squalo pescate in Adriatico, sia da un punto di vista morfologico che quantitativo, valutandone le differenze fra le specie, fra i sessi e, dove possibile, fra questi ultimi ed il periodo riproduttivo. Infine, si è valutato se fosse presente una correlazione significativa tra i melanomacrofagi e l’età nei maschi di palombo.
Valutazione quantitativa e macromolecolare di melanomacrofagi e lipidi epatici come strumenti promettenti per la conservazione degli elasmobranchi nel mare Adriatico

Abstract
The aim of this project is to identify new biomarker for the evaluation of the health status of sharks caught in the Adriatic Sea and their susceptibility to environmental changes. To reach this objective, melanomacrophages have been used as stress biomarkers on these organisms, since they are already widely used in teleosts, amphibians and reptiles. In this study, hepatic melanomacrophages have been evaluated in four species of sharks caught in the Adriatic Sea, both from a morphological and quantitative point of view, evaluating differences among species, sexes and, where possible, between these and the reproductive period. In conclusion, it has been assessed if there was any significant correlation between melanomacrophages and age of smooth-hound males.File | Dimensione | Formato | |
