Abstract

s m Abstract: The rapid growth of the marine aquaculture sector can indirectly lead to the accumulation of unresolved aquaculture waste in the sea. The IMTA cultivation system is one of the innovations developed in aquaculture activities to overcome aquatic environmental problems, such as the accumulation of waste from feed used in aquaculture activities. The concept is to combine the cultivation of several species with different trophic levels, such as fish that are fed and combined with seaweed which can absorb inorganic materials in the waters. So that the application of the IMTA system at aquaculture sites can maintain water quality for sustainable aquaculture. The purpose of this study was to determine the level of nitrogen absorption in Kappaphycus alvarezii seaweed with a longline system in the IMTA area in Ekas Bay waters. This study used a Randomized Block Design (RAK) with 4 treatments and each treatment was divided into 4 groups (North, South, East, and West). The treatment given was by planting seaweed at different depths, namely 50 cm, 100 cm, 150 cm, and 200 cm. Based on the results of the ANOVA test, it was shown that Kappaphycus alvarezii seaweed reared with an integrated cultivation system at different planting depths gave significantly different results on absolute weight growth and specific growth rate, but did not provide significant differences in the nitrogen uptake rate in all treatments.
