ECONOMIC CONSTRAINTS AND MARKET EFFICIENCY IN ARTISANAL FISHING TRADE: A STUDY OF GBARAMATU KINGDOM, DELTA STATE, NIGERIA

Abstract

Artisanal fishing in the Niger Delta region faces numerous economic constraints that undermine market efficiency, productivity, and profitability, yet empirical quantification of these constraints in oil-producing communities remains inadequate. This study identifies and evaluates the major economic constraints hindering the optimal performance of the artisanal fishing trade in Gbaramatu Kingdom, Delta State, Nigeria, within the framework of market efficiency theory. A mixed-methods cross-sectional survey design was employed, with data collected from 340 active fishermen and fish traders using structured questionnaires. Descriptive and inferential statistics were used for data analysis, including mean scores, ranking, and independent t-tests. Results revealed that environmental degradation (oil pollution) was the most severe economic constraint affecting market supply and price stability (mean score = 4.7 out of 5), followed by inadequate cold storage infrastructure leading to post-harvest losses (mean = 4.5), high cost of fishing gear escalating production costs (mean = 4.3), exploitation by middlemen creating market distortion and price inefficiency (mean = 4.1), and limited access to credit constraining working capital and enterprise expansion (mean = 4.0). Independent t-test showed that mean catch volume in areas with recent oil spills (25 kg/day) was significantly lower than in areas without spills (48 kg/day), t(338) = 9.83, p < 0.001, indicating substantial productivity losses and reduced market supply. The study concludes that environmental degradation, inadequate infrastructure, and limited access to finance and markets constitute major economic bottlenecks that constrain market efficiency, reduce fisherfolk income, and limit the sector's contribution to local economic development. Recommendations include environmental remediation to restore fishery productivity, investment in cold chain infrastructure to reduce post-harvest losses, establishment of microcredit schemes to enhance financial inclusion, and regulation of middlemen activities to improve price discovery and market efficiency.
