Morphology and histology of the liver of Oblada melanura (Linnaeus, 1758) (Teleostei: sparidae) in tripoli coast, Western Libya
The morphological and histological characteristics of the fish liver varies among species. No specific model described the liver of Teleostei. ‘Oblada melanura’ which is the most common sparid fish species in the Libyan markets with significant economic effects. The aim of This study aim to describe anatomical and histological structure of the liver of O. melanura. 215 specimens, with a total length ranged from 127 to 261 mm and the liver weight from 0.10 to 4.53 g, were obtained from Tripoli coast. The livers were fixed in 10% formalin, then sectioned at 7 µm and stained with hematoxylin and eosin and PAS. Morphologically, the liver is a triangle shaped with two lobes, bigger anterior and smaller posterior and has two surfaces: smooth dorsal and lobular ventral. Histologically, the largest proportion is the liver tissue, while the smallest is the pancreatic tissue, as well, blood vessels and bile ducts. The hepatocytes are polygonal, with spherical nucleus and a dark prominent nucleolus. Pancreatic tissue was observed in visceral portion of liver, formed by pancreatic exocrine acini, whilst no endocrine tissue found in the liver tissue. This study concluded that the exocrine gland of the pancreas of O. melanura found inside the liver tissue

Aucun modèle spécifique n'a décrit le foie de Téléostéen « Oblada melanura », poisson sparidé très commune sur les marchés libyens et à importance économique. Le but de cette étude vise à décrire la structure anatomique et histologique du foie d'O. melanura. L’étude de 215 spécimens de la côte de Tripoli, d'une longueur totale allant de 127 à 261 mm et de poids du foie de 0,10 à 4,53 g, a été effectuée. Les foies ont été fixés dans du formol à 10 %, puis sectionnés à 7 µm et colorés à l'hématoxyline et à l'éosine et au PAS. Morphologiquement, le foie est en forme de triangle avec deux lobes, un antérieur plus grand et un postérieur plus petit et il a deux surfaces : dorsale lisse et ventrale lobulaire. Histologiquement, la plus grande proportion est constituée d’un tissu hépatique, tandis que la plus petite est d’un tissu pancréatique, ainsi que des vaisseaux sanguins et des voies biliaires. Les hépatocytes sont polygonaux, avec un noyau sphérique et un nucléole proéminent foncé. Du tissu pancréatique a été observé dans la partie viscérale du foie, formée par des acinis exocrines pancréatiques, alors qu'aucun tissu endocrinien n'a été trouvé dans le tissu hépatique. Cette étude a permis de conclure que la glande exocrine du pancréas d'O. melanura se trouvait à l'intérieur du tissu hépatique.
