Management of Aquaculture Value Chains for Commercial Fish Production in South South Nigeria

This study examines the management of aquaculture value chains and identifies improvement opportunities for enhancing commercial fish production in South South Nigeria. Aquaculture is a rapidly growing industry in the South South zone, but value chain coordination failures, quality inconsistencies, and market access constraints are limiting the sector's commercial potential. This study uses a value chain analysis methodology, mapping the catfish production and marketing chain from hatchery through grow-out, processing, and retail in Rivers, Delta, and Bayelsa States. Data are collected from 40 hatchery operators, 80 grow-out farmers, 30 processors, and 25 retail traders through structured surveys and key informant interviews. Chain actor relationships, transaction costs, price distribution, quality management practices, and coordination mechanisms are assessed. Findings reveal that the catfish value chain is fragmented with weak vertical coordination, resulting in price volatility that adversely affects grow-out farmer planning and investment. Hatchery fingerling quality inconsistency is the most frequently cited upstream constraint, with mortality rates attributed to poor fingerling quality averaging 28 percent in the first month of grow-out. Processing and marketing quality losses from inadequate cold chain average 18 percent of harvest value. Prices received by grow-out farmers represent 42 percent of final retail price, with marketing margins concentrated in processing and retail stages. The study recommends forward contracting between hatcheries and grow-out farmers and cooperative cold storage investment as priority value chain improvement measures.
