Sammanfattning
Okwagbe community, situated along the Okwagbe River, a tributary of River Forcados, is a notable commercial hub recognised for its shrimp harvesting and trade. A study was therefore conducted on this river to determine its water quality, and distribution and abundance of Macrobrachium species. Water samples were collected fortnightly for three months (December 2024 to February 2025) from three sites along the river. Samples of crustaceans were collected with the help of local fishermen, and later identified. The water quality of the river was within acceptable ranges for fish production, and the values were generally not significantly different (p > 0.05) between sampling points. Three hundred and eight (308) Macrobrachium species were identified, primarily consisting of four species: Macrobrachium macrobranchion, M. vollenhoveni, M. felicinum and M. rosenbergii. Macrobrachium vollenhoveni was the most dominant, while M. felicinum the least dominant. Macrobrachium rosenbergii is rarely found in Nigerian rivers. This study also showed that the Okwagbe River has good quality water, suitable for aquaculture.
