Its revenues fell by 38.6 percent to VND70 billion, the lowest in six years.
The 157-year-old zoo in District 1 closed for two months from March 20 last year as part of Covid containment measures, and again shut on July 25 when a new wave began.
It set itself targets of VND114 billion in revenues and VND2.2 billion in pre-tax profits at the beginning of this year as the pandemic seemed to be contained.
The zoo subsequently revised the targets downward to VND81 billion and breakeven.
It raised ticket prices from VND30,000 to VND40,000 for children and from VND50,000 to VND60,000 for adults in January.
The zoo has over 125 species of animals and birds.
