Abstract

This study aimed to estimate the production of seaweed and assessed the physical and chemical suitability of waters for Gracilaria sp. Farmin in Morowali. Location of data sampling  consisted of two observation stations covering District Petasia (Station 1) with 6 substation samplings. Each substation consisted of 3 sampling points. Witaponda district (Station 2) consistied of 6 substations. Sampling was done in each substation with 3 point sampling.
