Prevalence of intestinal helminths of the Silver grunt (Pomadasys Kaakan) and black finned sea bream (Spondyliosoma cantharus) fish collected from Kuwait

Abstract

Climate change has caused extensive changes to marine ecosystems in recent decades; this might lead to an increase in marine disease. Parasite infestation in silver grunt and black finned sea bream is still few. This study aimed to determine the prevalence and intensity of intestinal helminthes of 60 sample of Silver grunt and 60 samples of black finned sea bream species collected from Kuwait fish markets. The result revealed that the total infection rate in each species was 58.3% and 33.3% respectively.  The endoparasite worms found in the intestine of Silver grunt were Procamallanus sinespinis which recorded the highest infestation rate 26.6% with intensity 2, followed by Aephnidiogenes senegalensis (25%) followed by Prosorhynchus indicus (18.3%) with intensity 4 for each, Anisakis physeteris and Aniskais simplex with infestation rate 11.6, 8.3%, respectively and intensity of 2 and 4, respectively. In addition, the endoparasite worms found in the intestine of black finned sea bream was Hysterothylacium fabri (8.3%). Histopathological examination of infested intestine showed necrosis, degenerative changes, and congestion of intestinal blood vessels.
