Tiger Shrimp is one of the marine biological resources that have high economic value and be used as a target catch of fishermen. The purpose of this research is to examine stock-based long-tiger shrimp weight through weight length relationships, mortality and exploitation rate of tiger shrimp in the Dompak waters Bukit Bestari District of Riau Islands province. This research was conducted in April 2014 until June 2014. Total samples analyzed during the research of 800 long-tail range 6-15 cm resulted in three age groups were separated by using Bhattacharya method with the help of FISAT II software. Value of the growth coefficient (K) be the highest in the female tiger shrimp from the data that is equal to 0.357 per year. As for the length weight relationship tiger shrimp male, female or a combination of both is negative allometric (the length faster than weight gain). The rate of exploitation of the highest tiger shrimp to black tiger shrimp combined data of 0.7 per year. Value of the tae of exploitation has exceeded the optimum exploitation of the value of 0,5.
