AB  - This present study provides an overview of the reproductive traits, including 
      ovarian development, spawning season, size at maturity (L(m) ), and fecundity of 
      Acentrogobius viridipunctatus - a high economic value fish in the Vietnamese 
      Mekong Delta (VMD). A total of 432 females were collected using trawl nets from 
      January to December 2020 at four sites, including Long Huu-Tra Vinh (LHTV), Trung 
      Binh-Soc Trang (TBST), Dien Hai-Bac Lieu (DHBL), and Tan Thuan-Ca Mau (TTCM). The 
      ovarian diameter was seen to increase from 2.09 (stage I) to 6.57 mm (stage V). 
      Histological analysis showed that the goby was a multi-spawner due to the 
      different oocyte stages found in stages IV and V of ovaries. It can release eggs 
      all year-round due to the monthly appearance of ovarian stages IV and V during 
      the study period, with the main peak in the 2-4 months of the wet season noted 
      with the highest value of gonadosomatic index at that time. The L(m) increased 
      from 6.6 cm at TBST to 9.4 cm at TTCM. This species displayed relatively high 
      fecundity, ranging from 5,481 to 130,683 eggs/female. The average fecundity of 
      this fish was 27,698 +/- 7,983 eggs/female at LHTV, 46,592 +/- 7,264 eggs/female at 
      TBST, 23,271 +/- 4,985 eggs/female at DHBL, and 31,408 +/- 2,515 eggs/female at TTCM. 
      Egg diameter ranged from 0.45 +/- 0.01 at DHBL to 0.50 +/- 0.01 at TBST. For 
      sustainable exploitation, local governments should ask the fishers to avoid 
      catching fish during the main spawning period, and the fish length at first 
      capture should be >L(m) .
