Abstract: Small pelagic fish has important economic value that cause vulnerablility to fishing activities. Fishing activity will affect the existence of the fish stocks and catches biomass. The purpose of this study was to assess the level of vulnerability of small pelagic fish resources in the Sunda Strait. The analysis of productivity and susceptibility of the catch will be expected to provide information of the stocks so that these resources can be guaranteed sustainability. PSA assessment results the Indian mackerel (Rastrelliger kanagurta), short mackerel (Rastrelliger branchysoma), Island mackerel (Rastrelliger faughni), Indian Scad (Decapterus russelli) and fringscale sardinella (Sardinella fimbriata) are included in low categories (≤1.6). The productivity value of the fishes showed different values while for the genus Rastrelliger fishes show the same results of susceptibility values. Based on these results, Indian Scad have the highest vulnerability index that is 1.58 while fringescale sardinella has the lowest vulnerability index by 1.37. After all, small pelagic fishes have vulnerability index by 1.28.
