Fish farming around cities can create jobs and supply food, but it can also put pressure on the environment. This study assessed the business activities, perceived environmental conditions, and management responses of people connected with fish-pond sites in Arulogun, a peri-urban part of Ibadan, Nigeria. Sixty-two pond sites were identified, and 213 people from those sites were interviewed. Simple percentages were used to summarise the answers. No direct measurements of water, air, or soil were taken. Commercial fishing was the most common business activity (39.4%), followed by recreational fishing and fish farming (21.1% each). Most respondents (52.6%) said their main management approach was sustainable fishing practices. However, 70.0% said waste disposal was inadequate, 32.4% noticed changes in water quality, and 27.2% noticed odours. Among those who noticed odours, 70.9% described them as unbearable. Training and education was the most common compliance approach (54.0%), while 72.8% reported no collaboration with external stakeholders. The findings point to clear gaps in waste handling, monitoring, stakeholder engagement, and pond siting. They describe what respondents perceived; they do not prove actual pollution or cause-and-effect relationships.
