This study appraised the value of ecological services offered by some aquatic ecosystem (Gbaji, Agboju, Topo and Ajegunle) in Badagry Division, Lagos, Nigeria in relation to the current physical and chemical status of these habitats. Data were collected via random administration of structured questionnaires to 168 households across the stations. Methods employed for collection of information include stated preference, divulged preference and market value approaches. Data collected were tested by one-way Analysis of Variance while differences in mean were separated using Least Significant Difference (p=0.05). Results showed that the highest mean annual income from irrigation for farming (#55,730 ±9,156.6), wage/salary for Boat builder/Net maker (#182, 265.4 ±11,655), water for domestic purpose (#64,256 ±16,426.5), water for washing body or clothes (#54,119.2 ±9,642.4), and industrial/domestic waste (#500,658 ±25,600) were obtained from Ajegunle station. On the other hand, highest mean annual income gotten from ecological services at Gbaji station includes fishing (#351,440 ±15,680), fish for sale (#312, 618 ±26,465.5), Wood and wood product (#59,387±10,792), medicinal plants (#18,116 ±7,680), firewood for sale (#56, 456.9 ±14,316.5), firewood for cooking (#24,145 ±6,425), livestock watering (#235,385 ±35,617) and religion rites (#70,528 ±16,178). Agboju station had highest income in sand for sales (#135,126 ±34,124), transportation (#728,358 ±48,526), sand for construction (#67,426.8 ±5,392.9), Original Research Article
