دراسة مقارنة مورفومترية و تشريحية و نسيجية لكبد إحدى الأسماك الغضروفية (Rhizoprionodon Acutus)‎ واحدي الأسماك العظمية (Sarda Orientalis)‎ بساحل حضرموت (خليج عدن)‎

Abstract EN

Specimens of Rhizoprionodon acutus and Sarda orientalis were collected from fishermen at Mukalla Sea (Gulf of Aden) in 2019.

These were brought to the laboratory of Biology, Faculty of Science, Hadhramout University.

Thirty samples of varying lengths and sizes were used for anatomical and histological examination of both species.

The morphometric study included measurements of the external lengths of the fish represented by the total length and spinal length.

The study also included measuring the total length and weight of the liver.

These measurements were recorded in graphs, annotated, analyzed and discussed.

(Haematoxylin and eosin) des were used to detect liver tissue components using light microscopy.

The microscopic examination of the transverse tissue sections of the liver showed that it is composed of hepatocytes that are arranged radially symmetrically around the central hepatic vein to form hepatic chains.

The bile ducts and blood sinuses also exist within the liver tissue structure in both species
