AB  - This study provided knowledge on testicular development, spawning reference and 
      length at first maturity (L (m) ) of Acentrogobius viridipunctatus-a target 
      catching fish for food supply in the southwest Viet Nam. A total of 528 
      individuals were collected using trawl nets from January to December 2020 at Long 
      Huu-Tra Vinh (LHTV), Trung Binh-Soc Trang (TBST), Dien Hai-Bac Lieu (DHBL) and 
      Tan Thuan-Ca Mau (TTCM). Five developmental stages of testis were found, and 
      testis diameter increased from  approximately 1.07 (stage I) to  approximately 4.82 mm (stage V). Testis 
      stage I consisted of spermatogonia (S) which shifted to primary spermatocytes 
      (SC1) in stage II. In testis stage III, SC1 was divided into secondary 
      spermatocytes (SC2). At this stage, testis consisted of S, SC1, SC2 and some 
      spermatid (ST). At stages IV and V, testis comprised mainly spermatozoa (SZ) 
      besides S, SC1, SC2 and ST, showing that this goby was a multi-spawner. Testis 
      frequency and gonadosomatic index analyses showed that this species released 
      sperms yearly, with a prominent peak in the wet season. The L (m) decreased from 
      9.3 +/- 0.3 cm at TBST to 9.0 +/- 0.3 cm at LHTV, 8.9 +/- 0.2 cm at TTCM and 6.5 +/- 0.5 
      cm at DHBL. Findings provided fundamental data to set up suitable fishing and 
      conserving strategies for this species.
