The article reports a significant decrease in the price of lobster in Phu Yen province, Vietnam, with grade 1 cotton lobster dropping to 800,000 - 850,000 VND/kg from 1.3 - 1.4 million VND/kg, and blue lobster reducing to 600,000 - 650,000 VND/kg from 700,000 - 850,000 VND/kg. This is attributed to increased farming costs and a decrease in demand. Despite a 79% increase in lobster output, the narrowed consumption market, largely impacted by Covid-19, has led to a drop in prices and increased pricing of shrimp.
