Marine aquaculture is undeniably a key future direction for the production of food. However, traditional aquaculture involves some significant drawbacks, the major one of which is the surplus discharge of organic matter and dissolved nutrients. To mitigate the environmental impact, integrated multi‐trophic aquaculture (IMTA) systems, which advocate the integration of fed fish with inorganic and organic extractive species, may offer a sustainable solution. This study focuses on an innovative experimental setting, integrating three marine macroalgae species (Ulva rigida, Gracilaria conferta, Hypnea musciformis) serially connected via two‐stage seaweed culture tanks to a finfish culture (the gilthead sea bream; Sparus aurata). The aim was to compare and assess the biofiltration and growth performances of the seaweeds, while altering their order in the two‐stage system. The results indicated U. rigida as the fastest growing species. Ulva rigida also displayed the highest total ammonia nitrogen (TAN) uptake rates and removal efficiency. The design allowed the production of high tissue protein and carbohydrate levels for potential biorefinery uses. Ulva rigida protein content averaged 23%, while that of H. musciformis and G. conferta averaged 25% and 18%, respectively. Hypnea musciformis and G. conferta grown under low nutrient conditions presented a significantly higher total carbohydrate content of nearly 50%, compared to 34% exhibited by U. rigida. In summary, the seaweed pairing in a two‐stage system did not inhibit the performance of each individual species and improved overall production. Consequently, it offers significant advantages for future IMTA systems.

South Sumatera has a very large shrimp pond, most of them were abandoned and untreated. The caused is the diseases such as white spot resulted in crop failure. It requires the effort in order to optimize and utilize the pond area. One of them by cultivating the Gracilaria sp seaweed which has a high economic value, easy to cultivate and tolerant to environmental changes. This study aims to analyze the parameters of water, analyze the growth rate of Gracillaria sp seaweed with Floating Net method. The results showed that the weekly growth of Gracilaria sp in the first week was highest in the fifth MFN with a weight of 5,540 grams and the lowest on the second MFN with 5,425 grams. At the second week the highest growth of third MFN (6,021 grams) and the lowest on fourth MFN (5,797 grams). On the third week, the highest growth of third MFN (6,625 grams) and the lowest fourth MFN (6,380 grams). On the fourth week, the highest growth of third MFN (6,950 grams) and the lowest on second MFN (6,864 grams). On the fifth week, the highest growth of first MFN (7,450 grams) and the lowest third MFN (7,010 grams) and on the sixth week, the highest growth of sixth MFN (8,215 grams) and the lowest third MFN (7,120 grams). The highest growth rate was at sixth week gain weight of 895 grams (sixth MFN). While the lowest was at fifth week with the addition of weight amounted to 60 grams (third MFN). The highest average growth rate actually occurred at the third week with the addition of average weight of 3,653 grams and the lowest was at the fifth week (2,193 grams). The highest absolute growth was found in the sixth MFN with a final weight of 8,215 grams and an absolute growth rate of 3,215 grams. While the lowest weight on the third MFN with weight 7,120 grams and growth rate of 2,120 grams. There was an increase of 1.424 -1.643 times the weight of the initial weight of planting. The daily growth rate ranges from 0.84515 -1.189% /day. The DGR value is highest in the 6th of MFN with the value of 1.18922 and the lowest was in the 3rd of MFN of 0.84515% days. All of the methods (MFN) show DGR results <2% /day. Parameters of pond water are still in the range for the cultivation of Gracilaria sp.

“…Until now, there are 185 kinds of Gracilaria sp that have been successfully identified (Guiry and Guiry, 2014). Gracilaria has a rapid growth rate (Abreu et al, 2011, Kim andKim et al, 2015;Wu et al, 2015;Kim et al, 2016;Gorman et al, 2017).

The production of Gracilaria sp is still not optimal and there are some opportunities left for production improvement by developing methods that use depth level as a planting media. A vertikultur method using bag nets is more effective and has higher production levels. This research aims to solve problems in cultivating Gracilaria sp seaweed by doing field optimization. Seaweeds were planted as many as 40 points for each 10 levels depth (BRL); 0, 70, 140, 210, 280, 350, 420, 560, and 630 cm from the surface. Environment and seaweed parameters were measured weekly. This research measures daily and weekly growth rate, absolute growth, and the total production. The data were analyzed using Anota test and BNJ further test. The research result shows that physic-chemistry water parameter is suitable for cultivating Gracilaria sp. The lowest weekly growth rate occurred in level BRL 10 in the first week while gaining weight as much as 9.351 gram/week. The highest growth rate occurred in level BRL 4 on the sixth week while gaining weight as much as 32.25 gram/week. The biggest absolute growth occurred in level BRL 4 with 214.87 gram and the lowest occurred in level BRL 10 with 161.45 gram. The biggest absolute growth rate occurred in level BR1 4 while gaining weight as much as 139.87 gram from the original weight and the lowest occurred in level BRL10 with 86.45 gram from the original weight. The best daily growth rate occurred in level BRL 4 with a growth rate of 2.53%/day and the lowest occurred in BRL 10 with 1.84%/day. Total production of Gracilaria sp from level BR1 1 -BR1 10 is 74,840 gram. The biggest production was obtained from level BRL 4 with the production of 8595 gram and the lowest in BRL 10 with 6458 gram. According to the anova test result and beda nyata jujur (BNJ), it shows that depth level (BR1 1 -BR1 10) gave no influence towards the growth rate of Gracilaria sp in the water of Kelagian Island. The vertikultur method by making use of depth level is both feasible and profitable for seaweed cultivators with production level ten times bigger.
