The operator of the country's largest zoo in Ho Chi Minh City saw revenues drop by half year-on-year to VND27 billion ($1.16 million).
The 156-year old zoo in District 1 closed for two months from March 20 as Covid-19 containment measures took effect.
Its loss was the third largest among seven loss making state-owned companies based in the city. The operator also has VND18 billion ($775,000) in debts, mostly salaries. Its 270 employees have agreed to a 30 percent salary cut this month.
It recently called for public donations to help the zoo care for its 1,500 animals, which require nearly five tons of meat, vegetables, fruit, and leaves daily.
The zoo has over 125 animal and 900 plant species.
