Effect Of Parasitic Infection On The Enzymatic Function Of The Internal Organs Of Scomber Scombrus (Mackerel) And Euthynnus Alltteratus (Small Tuna) (Misrata, Libya).

The assessment of fish health has acknowledged the significance of helminthology and haematology characteristics as crucial instruments. The utilization of blood parameter measurement has been a longstanding practice in the field of fish health monitoring. The current study aimed to examine the impact of an indigenous infestation of parasites on various blood parameters, including activities of liver, kidney function tests, lipase, amylase, Creatine phosphokinase (CPK), and Lactate Dehydrogenase (LDH). The present study was undertaken to investigate the parasitic infection in a sample of 100 fish. The sample consisted of 50 of Euthynnus alletteratus, and 50 Scomber Scombrus. These fish were gathered from the waters of Misrata city, located in Libya. Results revealed the presence of statistically significant differences across various indices in both Euthynnus alletteratus and Scomber scombrus. A significant positive association was seen between urea values and many organs in Scomber scombrus, with the exception of the external body. Similarly, in Euthynnus alletteratus, a significant positive correlation was found between urea values and various organs, except for the external body and nostrils. The results of the study indicate that there is a positive link between creatinine levels and several internal organs in Euthynnus alletteratus, with the exception of external body tissues. A favorable correlation was seen between sodium levels and various organs in Scomber scombrus, with the exception of internal organs and the stomach. There was a positive correlation seen between potassium, Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT), Alkaline Phosphatase (ALP), lipase, amylase, CPK, and total protein levels in several organs of both Euthynnus alletteratus and Scomber scombrus. A significant correlation was observed between LDH levels and several organs in both Euthynnus alletteratus and Scomber scombrus, with the exception of the external body in Scomber scombrus. In Euthynnus alletteratus, LDH levels were favorably connected with the nose, internal organs, and anterior intestine. [ABSTRACT FROM AUTHOR]
