The result of this study may contribute not only to fill in scientific knowledge gaps on WLR and slope value of this mudskipper, but also to stock assessment on this mudskipper. | TAP CHI SINH HOC 2014, 36(1): 88-92 A preliminery study on length-weight relationship of Boleophthalmus boddarti DOI: 10.15625/0866-7160/v36n1.4524 A PRELIMINERY STUDY ON LENGTH-WEIGHT RELATIONSHIP OF THE MUDSKIPPER Boleophthalmus boddarti IN SOC TRANG Dinh Minh Quang Can Tho University, *dmquang@ctu.edu.vn ABSTRACT: Boleophthalmus boddarti (Pallas, 1770) is one of mudskippers (Gobiidae), and a potential commercial fish in Mekong Delta, Vietnam. The study on the goby B. boddarti was investigated in Tran De district, Soc Trang province, Mekong Delta, Vietnam, to establish some basic population biology parameters. A total of 117 individuals were caught in mudflats of Tran De beach by deep net to determine length-weight relationships of this species. After determining sex by external features, total length (TL in cm), and body weight (W in g) of this goby were measured. This study ran for six months, from January 2013 to June 2013. The mean lengths of female significantly differed from value of male, whereas the average body weights of male and female were quite similar. The proportion of male and female groups were not substantially different. The length-weight relationships of total fish, male and female were highly correlated with high regression values which were 0.813, 0.866 and 0.767, respectively. The slope values of this mudskipper was 3.21±0.32 which was not significant higher cubic value (three), suggesting the growth relationship of this species was isometric growth and could be a potential fish for future aquaculture.

INTRODUCTION The blue-spotted mudskipper Boleophthalmus boddarti (fig. 1) is common one of an amphibious fishes inhabiting in the muddy area of coastlines and estuaries in Soc Trang province, Mekong Delta, Vietnam [7]. This species can use the air surrounding surface of the mudflat for breathing and use burrows as place of living, .
