Summary:The seaweed Sargassum sp. is easily damaged, especially in the fronds. This is one of the obstacles to its cultivation. This imposed the investigation of the use of the bag method to reduce this risk. The cultivation of Sargassum by the bag method and the investigation of its placement at several depths helps with information on appropriate methods for developing its cultivation. This study aims to determine the depth of water that provides the best growth for the seaweed using bags at multiple depths and the mesh bag method. The survey was conducted in the coastal waters of Kastela, in the Ternate Island district of Ternate City, Indonesia. The survey period was two months, from August to September 2021. The bag method was repeated 3 times at different water depths, at 0.5 m (A), 1 m (B) and 1.5 m (C). The data analyzed were absolute weight gain and relative growth rates. The results showed that the absolute weight gain of Sargassum in treatment A had the highest average absolute weight gain of 26.9 g, in treatment B it was 31.8 g, and in treatment C it was 25.9 g. Treatment B provided the highest absolute weight gain for Sargassum. The highest relative growth value of Sargassum was in treatment B, with an average value of 1.093%, followed by treatments A and B.
