How Much Do Farmers Expect to Implement for Traceability? Evidence From a Double-Bound Choices Experiment of Vietnamese Shrimp Aquaculture

Abstract

Traceability is considered the most important requirement for shrimp products exported to global markets. However, implementing traceability in shrimp-exporting countries is challenging because of limited production at the local supply chain and lack of financial welfare awareness. This study aims to investigate the expected farm-gate price for traceability implementation using a double-bound dichotomous choice experiment. The censored regression model is used to estimate the factors influencing the anticipated farm-gate price of shrimp farmers. The survey was conducted in Ca Mau Province, Vietnam, by interviewing 71 Penaeus monodon Fabricius, 1798, and 43 Penaeus vannamei Boone, 1931, farmers. To implement traceability, P. monodon farmers estimated the farm-gate price at 10.17 USD.kg-1 , while P. vannamei farmers expected 6.18 USD.kg-1 . Application of international quality assurance certifications, willingness to implement traceability, land used, culture methods, shrimp species, current farm-gate price, and variable costs affected the expected farm-gate price. The attractive anticipated farm-gate price compensated for the negative influence of applying international quality assurance certifications, indicating that the farmers were willing to implement traceability. This suggests that the application of certifications increased the ability to implement traceability in the shrimp supply chain. The attractive farm-gate price for certified shrimp products would enhance their willingness to implement the traceability of shrimp products.
