Abstract

The black sea cucumber Holothuria atra was used in integrated aquaculture with sea bass juveniles (Lates calcarifer) as the lowest and highest trophic level organism, alongside the seaweed Gracilaria sp. as an organic extractive organism. Therefore, this study aimed to assess the potential of integrated aquaculture combined with sea bass juvenile and seaweed to support the growth of the black sea cucumber. The experiment was carried out using a completely randomized design with 3 fish density treatments (50, 100, and 150 fish/m3), each integrated with 10 bags of seaweed and 4 individual black sea cucumbers. The study was conducted for 8 weeks and the fish were fed with trash fish at 10% of body weight. Water quality parameters were measured in situ every day except for TOM, ammonia, and nitrate which were measured at the beginning, middle, and end of the study. The results showed that the specific growth rate of the black sea cucumber ranged from 0.31-0.45%/day. The black sea cucumber was able to use the feed and metabolic waste produced by the culture of sea bass, showing the highest growth rate at a density of 100 fish/m3. Water quality parameters remained in ranges considered suitable for growth, except salinity. Furthermore, the black sea cucumber was found to have a strategy for adapting to fluctuations in salinity, as shown by the ability to survive at 15 ppt.Keywords:Sea bass juvenilesSeaweedSalinityTOM

Abstract

Maluku, as an archipelagic region, has marine resources, yet utilization remains suboptimal, particularly in coastal areas such as Negeri Porto, Central Maluku. Community activities are dominated by traditional fishing, while knowledge of aquaculture as an alternative for sustainable resource use remains limited, especially among younger generations. This condition motivated the Aquaculture Goes to School program to improve marine literacy and introduce aquaculture concepts based on local potential, particularly sea cucumbers. The activity employed a participatory-educational approach through presentations, interactive discussions, and aquaculture simulations. Participants included students from SMA Negeri 4 Porto, teachers, and university lecturers, with students positioned as active participants in contextual learning. The results showed that students had good knowledge of marine biodiversity, but their understanding focused on capture fisheries and did not include aquaculture concepts and economic value. After the activity, students’ understanding of aquaculture, the economic potential of marine resources, and sustainable management improved. Pre-test and post-test evaluations across four indicators indicated that locally based education has the potential to improve marine literacy and sustainability awareness. This program is relevant to support blue economy strategies. However, interest, motivation, and perception changes were recorded only through one-day observations and were not used to infer long-term attitudinal changes.
