Author(s): Hala Khidir Hassan Osman, Salah Eldeen Yagoub Mohamed and Mohamed Elamin Hamza

Abstract: This study aimed to investigate the effects of parasites infection on tissues and biometrics of fishes collected from the Daim Mayo lagoon. The study was conducted in the period from April 2014 to May 2015. The results obtained indicated significant differences in biometric parameters between healthy and infected fishes (p˂ 0.05). Values of liver somato index, gonado somato index and condition factor were higher in healthy fishes. Hypertrophy and Hyperplasia of gill lamellae were detected in the gill filaments of fishes Mugil cephalus and Rastrelliger kanagurta due to infection by Lernanthropus sp., Aella sp. and Gnathia sp. parasites. The presence of necrosis and edema were detected in the mouth roof of Mullets M. cephalus due to infection by Cymothus sp. Damage to the intestinal villi, lymphocytes infiltration, edema, focal necrosis. Haemorrhage and separation of submucosa layer from muscular layer were observed in the intestine of fishes Chanos chanos and M. cephalus that were infected by nematode Procamallnus sp. On the other hand, parasitize intestine of M. cephalus fishes with acanthocephalan Sclerocollum sp. showed lymphocytes infiltration and congestion in arteries, damage in intestinal villa and thickness in the muscular layer. The liver of Caranoide flavogattus and M. cephalus fishes showed histopatholgical alteration in tissues which include focal necrosis in the liver parenchyma, haemorrhages, melanomacrophages aggregation and atrophy of liver sinusoid.
