Aim: This study was conducted to contribute data on the reproductive biology such as sex proportion, spawning season and pattern, fecundity and its relation to fish size, and length at first mature of the commercial fish Glossogobius sparsipapillus in Tra Vinh province, Vietnam.
Methodology: Fish was collected monthly using trawling nets at four sampling sites during dry and wet seasons between July 2019 to June 2020. Next, fish was stored in ice before transporting to the laboratory. In laboratory, total length, body weight, and sex before removing gonads were examined
histologically.
Results: Female G. sparsipapillus (806 individuals) out numbered males (591 individuals). This goby was a multi-spawner as different developmental stages of oocytes and spermatocytes were present in the cross-section of testes and ovaries. A combined analysis of frequency of mature ovaries and GSI showed that this goby could spawn throughout the study period with the mean peak from July to October. The batch fecundity was 17,537 SE and related positively to fish length and weight, indicating it increased as fish grew.
Interpretation:This study results in an enhanced understanding of this species' reproductive biology for better sustainable management and brood
