Squid, known with scientific name Loligo sp, is a group of cephalopods or a type of Mollusca living in the sea, with horizontal distribution area from coast to open sea and vertical distribution area from sea surface to thousands of meters under sea surface in water column. Until now, squid production still depends on the natural stock since there is no study on technology for its culture, thus it is a concern that if the production keeps increasing, the resource preservation will be threatened. Therefore, for the purpose of sustainable management, it is necessary to study the parameter of population and biomass of squid resource through an analysis on the dynamics of population, including age, growth, mortality and yield per recruit. This research was conducted for 3 months from June - August 2020 aiming at analyzing the parameter of population of squid resource and the exploitation rate in Ternate Island waters using observation method, stock study and population analysis. The research result finds that the squid resource in Ternate Island waters still has stable growth parameters, including maximum length (L∞) 97.13 mm, growth coefficient (K) 0.23 per month, t0 1.26 with total, natural mortality, and catch respectively 0.74, 0.50, 0.24 and exploitation rate 0.32 in which these values show lower exploitation rate than expected utilization value of 46.0%.
