Water Quality and Haematological Indices of Clarias gariepinus from Ogun River (Nigeria)

Abstract

This study was conducted to assess the effect of water quality of the Ogun River on the haematological indices of the African catfish Clarias gariepinus. Samples of water and Clarias gariepinus were collected from Ogun River (Station I, Opeji and Station II, Lafenwa) to determine and compare effects of possible differences in water quality on haematological parameters of Clarias gariepinus. The results demonstrate that higher index values were recorded at station II than Station I for almost all the physicochemical parameters and only sulphate values from Stations I and II were statistically significant (P < 0.05).RÉSUMÉ: La qualité de l'eau et les indices hématologiques pour Clarias gariepinus dans la rivière Ogun (Nigéria).Le but de cette étude a été d'évaluer l'effet de la qualité de l'eau de la rivière d'Ogun sur les indicateurs hématologiques du poisson chat africain Clarias gariepinus. Des échantillons d'eau et des poissons de l'espèce C. gariepinus ont été collectés de la rivière d'Ogun (Station I, Opeji et Station II, Lafenwa) afin de mesurer de comparer les effets possibles des différences de la qualité de l'eau sur les paramètres hématologiques de C. gariepinus. Les résultats ont mis en évidence le fait que dans la station II ont été enregistrés des valeurs plus grandes que dans la station I pour presque tous les paramètres physiques et chimiques mais ils ont aussi montré le fait que seul l'indicateur sulfate a des valeurs statistiquement significatives (P < 0,05).REZUMAT: Calitatea apei și indici hematologici la Clarias gariepinus din râul Ogun (Nigeria).Prezentul studiu a fost efectuat pentru a evalua calitatea apei în râul Ogun, cu privire la indicii hematologici ai somnului african, Clarias gariepinus. Au fost colectate eșantioane de apă și pești din specia Clarias gariepinus din râul Ogun (stația I, Opeji și Stația II, Lanfewa) pentru a se determina și compara efectele posibilelor diferențe ale calității apei asupra parametrilor hematologici Clarias gariepinus. Rezultatele au arătat că în stația II s-au înregistrat valori mai mari decât în stația I, pentru aproape toți parametrii fizico-chimici și doar valorile pentru indicele sulfat din cele două stații au fost statistic semnificative (P < 0,05).

“…One of the most important food sources which are invaluable for protein and industrial products are fish from freshwater and ocean ecosystems (Monte-Luna et al, 2016). In spite of the fact that Nigeria is characterized by a relatively rich fish fauna (Olopade, 2013;Adaka et al, 2015;Olopade et al, 2015) this country is the fourth largest importer of fish in the world, where the top suppliers are the United States and Chile, but fish is also sourced from Europe, Asia, and a few African countries, including Mauritania, Algeria, and Mauritius (Daniels et al, 2016;Lawal-Are et al, 2021). More than 41% of the total animal protein intake in Nigeria is obtained from fishery products because it is relatively cheaper than other animals meat and the total fish consumption rate has risen to 2.66 million metric tons annually (Onyia et al, 2014;Moruf et al, 2019).…”
