This book assesses the perceived impacts of weather variability on aquaculture production in Ondo State, Nigeria. A multi-stage sampling procedure was used to select eighty respondents, with data collected through a structured questionnaire. The analysis employed descriptive statistics and a 5-point Likert rating scale. Results showed that a significant majority identified solar radiation (high temperature), strong winds, and rainfall patterns as critical factors affecting their aquaculture practices. Among these, wind speed was most frequently cited as having a high impact. Most respondents indicated that weather variability has reduced water quality, increased disease incidence, and altered reproductive patterns. It is recommended that government agencies and non-governmental organizations (NGOs) collaborate to subsidize the cost of adaptive technologies.
