Interest in organically grown food products has considerably increased in response to concerns of food safety, human health, animal welfare and the environment. In spite of potential development, available information about organic aquaculture farming as well as its economic indicators are still very much limited. The paper was aimed to evaluate the status quo, describe the value chain and distribution of cost-profit among chain actors in Ca Mau province, the largest certified organic shrimp producer inVietnam. This research was conducted from July to November 2013, through directly interviewing 62 respondents, including 56 actors participating in the value chain of organic shrimp and 6 key managers from Mangrove forest Management Units and Department of Agriculture and Rural Development of Ngoc Hien and Nam Can Districts, Ca Mau province. The result showed that there were five distribution channels of certified organic shrimp production, in which three key channels were “Farmers – Middlemen – Processors”, “Farmers – Middlemen – Wholesalers – Processors” and “Farmers – Wholesalers – Processors”. All channels were characterized by unequal distribution of total added value (TAV) and income among chain actors. The farmers produced shrimp with average cost of 104.9 thousand VND/kg and sold the product to middlemen with the price of 197.1 thousand VND/kg, contributing to 53.3% of TAV. The difference in selling price between middlemen and wholesalers was 24.9 thousand VND/kg. Middlemen shared 14.4% TAV. Wholesalers resold about 98.5% of raw shrimp to processors at the price of 244.5 thousand VND/kg, accounting for 13.0% of TAV. Finally, the processors exported shrimp and got a profit of 12.4 thousand VND/kg, allocating 19.4% of TAV in the value chain. The total net income was unequally shared, mainly focusing on processors (65.90-97.54%) due to big discrepancy in production scale. Major solutions for development of organic shrimp program were suggested for each level of participation of actors as follows: i) Hatcheries needed to enhance production scale of and continuously improve the quality of seed; ii) Farmers abided by regulations of Naturland standard; iii) Collectors should strengthen the cooperation with farmers and processors; iv) Processors played key role in organizing technical training courses, establishing clubs/cooperatives, marketing and promoting trade name, and v) State and local government encouraged and created advantageous conditions for expanding organic shrimp farming model.
