The Diversity of Mudskipper Fish Family Gobiidae in Mangrove Area, Seberang District, Tanjung Jabung Regency, West Jambi

Mudskipper fish (Periopthalmus spp) is a member of the order Periophthalmini, family Gobiidae and subfamily Oxudercinae. This fish is known by the names of gunshots, tempakul, timpakul and belacak. Mudskipper fish have a role as a bioindicator in mangrove ecosystems, so its existence and diversity needs to be known. This research is quantitative exploratory which aims to analyze the diversity of mudskipper fish in the mangrove area of ​​Seberang District, Tanjung Jabung Barat Regency and determine environmental factors that affect their lives. The technique for determining the sampling station was purposive sampling. Sampling was carried out at 3 stations in two different villages, namely Kuala Baru Village and Seberang Village. The survey method was conducted at 2 different stations. Each sampling station area in Seberang Village is 50 x 20 m, while in Kuala Baru village it is carried out on 2 transect lines with a transect length of 35 meters and consists of 3 plots measuring 5 x 5 m and spaced 10 m between plots. The results showed that there were 2 species of 2 general of mudskipper fish, namely Periophthalmodon schlosseri and Boleophthalmus boddarti. The most abundant type of Boleophthalmus boddarti was obtained with 36 individuals out of a total of 45 individuals. The index of diversity of mudskipper fish species at the three stations was low ranging from 0.3-0.6 and the dominance index ranged from 0.6-0.8. Environmental conditions are water temperature 31-33°C, soil temperature 28-35°C, salinity 13-15 ppt, water pH 6.8 and soil pH 6.2-6.8. DO ranges from 5.9 to 6.8 mg/L, the soil texture is clay type, dusty loam, and clay. It can be concluded that the diversity of mudskipper fish in Seberang sub-district is low, with an abundant number found in the Boleophthalmus boddarti fish species.
