Abstract
Parasitic infection of fish is seen worldwide, and they are of particular interest in the tropics. Reports indicate that parasite infections in fishes lead to a disruption in aquaculture production. This study was undertaken to determine the association between physicochemical parameters and the abundance of Wenyonia sp Woodland, 1923 in Synodontis clarias collected from Lekki Lagoon, Lagos, Nigeria. A total of 180 Synodontis clarias were investigated between April 2019 and March 2020. The physicochemical parameters such as temperature, pH, turbidity, electrical conductivity, dissolved oxygen, and total dissolved solids of the surface water at the Lekki Lagoon were assessed in situ using the Horiba U50 multi-water sampler at three (3) Points, 500 metres apart. There was a positive correlation between parasite abundance and all the physicochemical parameters investigated. Water temperature showed a positive correlation with pH and turbidity and a negative correlation with electrical conductivity, dissolved oxygen, and total dissolved solids. The results showed that the statistical T-value (-2.72) of the parasite abundance between the male and the female fish was lower than the critical T-value (1.98), indicating no significant difference in the levels of infections between the male and female fish samples. In conjunction with future data, the data produced in this study can be used in monitoring the aquatic habitat for informed remediation of the lagoon to aid the preservation of the ecological services rendered by the aquatic ecosystem.
