Hi, Chung shang hui,
Thank you for the update... You are very much correct.
As reported by Zuridah Merican, Ph.D. (2021) adapted from the May/June 2020 issue of the Aqua Culture Asia Pacific Magazine on pp 24-29. and I quote: “for Vietnam’s shrimp feed market, there are four market leaders (CP Vietnam, Grobest, Sheng Long and Uni-President) contributing almost 78% of the production”
Kind regards,
Nelson
