“…The collected specimens were preserved in 5.0% formalin and classified based on their external morphology according to the report of Tran et al (2013) in the laboratory. The fish sexes were differentiated based on the morphology of urogenital papilla, e.g., round in females and narrow in males (Dinh et al, 2020). In the zoological laboratory, B. koilomatodon specimens were measured for total length (nearest 0.1cm) and weighted (nearest 0.01g).…”

The study aimed to investigate morphometric and meristic variability in the mud sleeper Butis koilomatodon (Bleeker, 1849) in the Mekong Delta. This species is a commercial fish species with a small-size and is mainly distributed in some coastal areas from Tra Vinh to Ca Mau provinces. In the present research, the parameters of morphometry and measurement, including the head length, body depth, eye diameter, distance of the two eyes, and the interrelationships among the morphometric variables, were determined. The results revealed that the total length and weight of the fish changed by sex, season, habitat, and the interaction between the seasons and habitats. Likewise, the meristic criteria were different between males and females, and the dry and wet seasons, but not by their interactions. The growth rate of males was faster than females. The outcomes also showed that the body size of this species was larger in the dry season and the largest fish were found in Duyen Hai and Tra Vinh provinces. The Findings would be useful not only for further effects of environmental factors on morphology but also for comparisons between congeners Butis morphologically.

“…Tinh trùng thấy rõ là các tế bào nhỏ có đuôi với phần đầu chứa nhân bắt màu đậm hơn (Hình 3d). Sự phát triển tinh sào ở cá bống cát trải qua các giai đoạn có sự phát triển gần như tương đồng với các loài như: cá kèo vảy to Parapocryptes serpersater [10], cá bống sao Boleophthalmus boddarti [13], và cá bống trân Butis butis [14], cá bống trứng Eleotris melanosoma [15], cá bống mít Stigmatogobius pleurostigma [16] và cá thòi lòi Periophthalmodon septemradiatus [17]. Ở giai đoạn I, hình thái ngoài gần như giống nhau ở các loài các nêu trên, với tinh sào đều mảnh, nhỏ, dẹp, nằm sát vào cột sống của cá.…”

This study was conducted in the coastal estuaries in Bac Lieu and Ca Mau provinces in order to provide data on morphological and histological characteristics of as well as the spermatocyte development at every stage of the development of testis of goby Glossogobius sparsipapillus. The analysis results of 226 fish individuals, collected monthly from April 2019 to September 2019 by using the bottom nets, showed that the testis of this fish was double strands. In stage I, testis was small, thin and transparent; and the weight and size of testis increased from that stage onward. The colour of the testis became ivory white with the smooth and puffed surface. Spermatogonia were found through the cross-section of the testis in stage I, and then they were divided into primary spermatocytes and secondary spermatocytes, which were interlaced in stage II. In stage III, spermatids appeared in testicular lobes and developed into sperm in stage IV. This fish species is a multiple spawner during the breeding season, because there are several developmental stages of spermatocytes in their histology. This result is the basis for further research on artificial reproduction of this fish.

“…indicated that semelparity and iteroparity are two main reproductive strategies. Iteroparous is found in most gobiid species (Miller, 1984;Dinh et al, 2016;Dinh et al, 2020). There is a strong relationship between the strategy of reproduction and fishery (Miller, 1984;Komolafe and Arawomo, 2007;Dinh et al, 2020).…”

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 stock study in studied regions.
