OA Akinrotimi, OMG Abu, IF Ibemere, CA Opara


The economic viability and marketing strategies of periwinkle species in twelve major markets across Rivers State Nigeria were investigated using structured questionnaires. The results indicated that marketing strategies are enroute, through harvesters (collectors), to wholesalers (those who purchase in small quantities and process it) and lastly to consumers. The periwinkles are sourced from eight major locations in the state, from where they supplied major markets in the area. Across the 12 markets under survey the specie Tympanotonus fuscatus var radula (smooth spine) occurred more (54.6% - 89.8%) than the Tympanotonus fuscatus var fuscatus (thorny spine) (95.4% to 45.6). The study also showed that the cost of processed and unprocessed periwinkle varied across markets, the highest cost (N200.00k) being recorded at Choba market, and the lowest price (N75.00k) at Kono waterside markets. The consumer preference study showed that roasted periwinkle was more preferable (58.2%), while the empty shell was less preferred. Parboiled meat was observed to be the most patronized product of periwinkle (55%), while the empty shell recorded the lowest (4.6%). In the utilization of periwinkle shell, usage of the shell as building material (gravel) occurs highest (66.6%), while its usage in decoration of buildings was lowest (4.0%). From these results, it could be concluded that periwinkle is an important marine organism since every part of the specie is useful and economically viable.
