Phân tích các yếu tố ảnh hưởng của các mô hình liên kết trong nuôi cá tra (Pangasianodon hypophthalmus) ở Đồng bằng sông Cửu Long, Việt Nam

Abstract

The study was conducted from February 2018 to June 2019 in four main provinces of striped catfish farming in the Mekong Delta including An Giang, Dong Thap, Vinh Long and Can Tho. Structured questionaries with the stratified random sampling were used to collect data from 271 striped catfish farms with different linkage models. Binary logistic regression model was used to analyze factors affecting the linkage models. The results from the regression model identified four factors that affect the linkage model arranged from high to low importance including educational level of farm owner, farming area, profitability and operational costs. However, the share of benefit and risk among related actors should be considered as important factors for a long-term linkage of the model. In addition, striped catfish farms had a contract with processing plants obtained the highest yield (517 tons/ha/crop) and profit margin (17.1%) if compared to those of other linkage models.
