Abstract
The study was carried out on 120 Synodontis filamentosus (11 – 26.5cm, 22 - 88g) and 120 Tilapia zillii (15 - 21cm, 67 – 187g) captured from Epe Lagoon, Lagos State, Nigeria. The aim was to comparatively analyze the bioaccumulation of polybiphenyl chlorides (PCBs) and prevalence of parasitic helminthes in S. filamentosus and T. zillii relative to their respective habits. The comparison was done using indices such as bioaccumulation factors, biota-soil accumulation factors, and parasite prevalence. Profiles of PCB accumulation showed that T. zillii followed by their endoparasites accumulated outstanding concentrations, suggesting that T. zillii might be a greater bioaccumulator of PCBs than S. filamentosus. Significant biota-soil accumulation factors observed in the T. zilliii and their endoparasites were accompanied by significant sorption capacities of PCBs into the soil at impacted locations of the lagoon. This implies that T. zillii accumulated significant PCB from the soil and shared with its endoparasites, justifying host-parasite xenobiotic transfer. S. filamentosus had higher levels of parasitic infections than T. zillii, males of both species were more infected than the females. The intestine and liver tissues of S. filamentosus showed greater alterations than the tissues of T. zillii. Findings showed that S. filamentosus is a better bioindicator in histopathological studies while T. zillii is a better bioaccumulator.
