Since is no initial data concerning the existence offamily Ariidae resources. The method for data collection of this research was survey, with samples collected from Korowelang ( Location I), Semarang ( Location II), and Morodemak ( Location III). Each location consists of 5 depths, about ± 1m, ±5m,:!: 10m, ± 15m, and> 20m. Sampling parameter using Push Net in the depth about ± 1 m, and Beam Trawl in the depth of± 5m, ± 10m, ±15m, and > 20m. The Size Beam is 2 x 0,6 m, and Mesh Size of body and cod end each of 2,5m and 0,5 cm. Respectively, the abundance was analized using Swept area Method. Total Dernersal fish found during the research was 6.561 Ind, the most abudance (Ind/ 100m) was from ± 15m. The Distribution of Demersal fish tends to take place randomly, and bigger variety found on most species.
