Determination of Optimal Harvest Time for Catfish Based on Market Demand in Abuja, FCT

This study determined the optimal harvest timing for farmed African catfish (Clarias gariepinus) based on an analysis of market demand, price dynamics, and consumer preferences in Abuja, Federal Capital Territory, Nigeria. Understanding market-driven harvest decisions is essential for improving the economic viability of urban and peri-urban aquaculture operations supplying high-value city markets. Primary data were collected through surveys of 75 fish retailers, 30 food service businesses, and 100 consumer respondents in major Abuja fish markets and retail centres. A parallel growth trial tracked catfish growth over 20 weeks in a private farm in the Bwari Local Government Area. Harvest weight preferences, seasonal price peaks, willingness to pay for different size categories, and market saturation periods were analysed. Results indicated that consumer demand was strongest for fish weighing between 800 grams and 1.2 kilograms, which also attracted a 28 percent price premium over smaller sizes. Market price analysis revealed seasonal peaks during festive periods, particularly December and Easter, when prices rose by 35 to 45 percent above average. Growth data showed that catfish reached the 800-gram market size at approximately 14 weeks under standard management. The study concludes that farmers supplying the Abuja market should target harvest windows aligned with festive demand peaks, staggering stocking dates accordingly to maximise returns.
