Value Addition and Profitability in Fish Marketing: Evidence from Southwest, Nigeria

This study investigates the role of value addition in enhancing profitability among fish marketers in Southwest Nigeria. Using data from 769 marketers in Lagos, Ogun, and Ondo States, the research evaluates the types of value-added products, returns on investment (ROI), and the factors influencing product choice. A descriptive survey design, and ROI analysis were applied. The research analyzes pooled data on nine fish products (Fresh, Smoked Fish, Fried Fish, Fish Fillets, Dried Fish, Fish Powdering, Frozen Fish, Fish Barbecue, and Fish Kilichi) and ten fish types (Catfish, Tilapia, Shiny Nose, Panla, Asa Fish, Croaker, Barracuda, Abo, Okodo, and Obokun). Data were gathered from fish marketers and processors, targeting nine fish products. Results indicate that fresh fish dominates the market (57.26%, 769 instances), with Catfish leading (31.20%), followed by Asa Fish (13.74%) and Shiny Nose (11.14%). Value-added products, notably Smoked Fish (27.78%) and Fried Fish (21.28%), are prevalent, reflecting significant adoption of processing techniques to enhance shelf life and profitability. Niche products like Fish Powdering (1.30%) and Fish Kilichi (0.65%) are limited to specific fish types, indicating specialized market niches. Findings reveal that smoked fish is the most common and profitable value-added product. Female marketers dominate the sector, and their product choices are influenced by experience, credit access, and training. The study also highlights regional variations, with Ogun State leading in dried and smoked products due to its proximity to aquaculture hubs, while Lagos excels in frozen and filleted fish owing to better infrastructure and market access. Overall, value addition not only boosts profitability with profits per kg reaching ₦4,600 for dried Asa fish but also contributes to food security by increasing fish supply and nutritional value, aligning with Nigeria's evolving blue economy.The study recommends investment in infrastructure, financial support, and capacity building to improve market outcomes. These results provide empirical insights to strengthen Nigeria's fishery value chain in line with SDG targets.
