Abstract

Highly nutritious insects, such as black soldier fly (BSF) larvae, also referred toas maggot, have been evaluated as feed in monoculture systems, but their use in multi-trophic systems has not been previously investigated. This study used maggot-based feed in a multi-trophic system on a laboratory scale to evaluate the survival and growth performance of tilapia (Oreochromis niloticus). Tilapia were cocultured with freshwater lobster, freshwater clams, and paddy. Four experimental diets were used including a commercial pellet as a control (CP), live maggots (LM), dried maggots (DM), and supplemented maggots (SM). Tilapia (initial weight, 4.1 ± 0.2 g) and other organisms were reared in plastic tanks (water volume 50 L) and randomly distributed into 12 tanks, each containing 20 individual tilapia. The experimental diets were given four times a day at a feeding rate of 10% tilapia biomass. After 28 days of feeding, the survival and growth of tilapia on the CP diet were 90.0% and 2.8% day-1, LM 93.3% and 2.7% day-1, DM 93.3% and 3.3% day-1, and SM 90.0% and 3.1% day-1, respectively. There was no significant effect (P > 0.05) on the survival performance among the experimental diets. However, the growth confirmed by Specific Growth Rate (SGR) showed a significant effect (P < 0.05). SGR values were found to be significantly higher in the DM and SM diets than in the CP diet. An important finding of this research is the potential of maggot-based feed to increase the growth of tilapia in multi-trophic systems without impairing their survival.

Abstract

Recent studies show the importance of artificial structures in supporting the recovery of coral reef ecosystems, particularly in improving the association of reef fish that play an important role in the ecological balance of tropical seas. The innovation in the use of turtle-shaped transplant skeletons is the main highlight because it is able to attract higher biodiversity than conventional methods. This study aims to evaluate the parameters of water quality, diversity index, and abundance of reef fish species associated with the transplant structure. Data collection was carried out using the Underwater Visual Census (UVC) method at two different sampling moments of the season. The first sampling is during the rainy season, and the second sampling is during the dry season. The environmental parameters measured included salinity, temperature, pH, and water currents, while biotic indicators included the Shannon-Wiener diversity index (H') and species density (ind/m²). The results showed that all water quality parameters were within the standard range of marine quality for marine life (First side: salinity 32.6 ppt; temperature 31 °C; pH 7.7; current 0.05 m/s and second sampling: salinity 32 ppt; temperature 30.6 °C; pH 7.5; current 0.07 m/s). A total of sixteen species of fish were found to be associated with transplanting media, including Plotosus lineatus, Siganus margaritiferus, Ptereleotris heteroptera, Abudefduf vaigiensis, Chromis atripectoralis, Aeoliscus strigatus, Petroscirtes mitratus, Chaetodon octofactiatus, Abudefduf sexfactiatus, Meiacanthus grammistes, Cheilodipterus artus, Cheilinus chlorourus, Siganus virgatus, Chrysiptera parasema, Synanceia verrucosa and Sargocentron xantherythrum. The first sampling showed a lower diversity value (H' = 316.76; D = 2.3 ind/m²) compared to the second sampling (H' = 322.10; D = 3.28 ind/m²). This difference is influenced by dry season conditions that lead to increased clarity and penetration of sunlight, which significantly supports the abundance of biota. These findings confirm the potential of innovative transplant structure design in supporting sustainable coral fisheries conservation.

Abstract

The two main sectors, agriculture and fisheries, play an important role in ensuring food security and community nutrition. However, limited land, water resources, and energy are problems that these two sectors often face. Research on FCR on a GIS-based floating-bed model IAA system can provide important information on how to improve the efficiency and productivity of the system. This study aims to determine the effect of the extractive species placement model on the Feed Conversion Ratio (FCR) of tilapia (Oreochromis niloticus) in the Integrated Agriculture Aquaculture (IAA) system of the GIS-based floating-bed model. The study used a Complete Random Design (RAL) with three treatments and three replicates. The treatments tested were Treatment A (no floating-bed transfer during maintenance), Treatment B (10-day interval transfer), and Treatment C (20-day interval transfer). The research was carried out for 90 days in the pool of the People's Hatchery Unit (UPR) Sipurennu, Citta District, Soppeng Regency. The main parameter observed is the FCR value. The results showed that the FCR values in Treatment A, B, and C were 1.03, 1.09, and 1.08, respectively. ANOVA analysis showed no significant difference between treatments (F=0.389, Sig.=0.694). The conclusions of the study showed that the effect of the extractive species placement model on the Feed Conversion Ratio (FCR) of tilapia (Oreochromis niloticus) in the Integrated Agriculture Aquaculture (IAA) system of the GIS-based floating-bed model effectively resulted in a low FCR value in the range of 1.03-1.09, with the lowest value at treatment A (without floating-bed transfer during maintenance).

Abstract

This study aimed to identify potential fishing grounds for the blue octopus (Octopus cyanea) around Barrang Caddi Island, Makassar City, by integrating field observations with remote sensing-based oceanographic parameters. A quantitative descriptive survey was employed by accompanying local fishermen during 21 fishing trips using handline (handline hook) gear. Geographic coordinates of fishing locations were recorded using a Global Positioning System (GPS), while satellite-derived sea surface temperature (SST), salinity, and chlorophyll-a concentration were obtained from Aqua MODIS and HYCOM datasets. Spatial analysis was performed using Geographic Information Systems (GIS) to delineate potential fishing zones based on the integration of catch distribution and environmental variables. The results revealed that potential fishing grounds were predominantly located in shallow coral reef habitats surrounding Barrang Lompo and Barrang Caddi Islands. Sea surface temperature averaged 29.24°C, salinity reached 30.8 PSU, and chlorophyll-a concentration ranged from 0.6 to 0.8 mg m⁻³, indicating environmentally favorable conditions for Octopus cyanea. Moderate-potential fishing zones occupied the largest spatial extent, whereas high-potential areas were concentrated near structurally complex coral reef ecosystems. These findings demonstrate that remote sensing provides an effective approach for identifying productive octopus fishing grounds and can support sustainable fisheries management, improve fishing efficiency, and provide scientific information for spatial planning and resource conservation in the Spermonde Archipelago.

Abstract

This study represents a potentially groundbreaking exploration into the dual integration of agriculture and aquaculture (IAA) systems in brackish water. The objective of this work was to assess the production performance of the IAA system under various species combination scenarios, which are pivotal in multi-species cultivation. Conducted over an 80-day period, this study employed three species combination scenarios: milkfish and rice (Scenario 1), milkfish, tiger shrimp, and rice (Scenario 2), and milkfish, tiger shrimp, mussel, and rice (Scenario 3). A floating-bed system was utilized for rice cultivation in all scenarios. The pilot scale experiment was meticulously designed, including tarpaulin ponds, acclimatization, feed, and aeration to establish a conducive environment within the system. Results revealed proportional species growth, with the mortality rate (MR) of milkfish, tiger shrimp, and rice showing no significant impact (P > 0.05) from species combinations. However, significant differences (P < 0.05) were observed in the weight gain (WG) and specific growth rate (SGR) of milkfish, as well as the height gain (HG) of rice among species combinations. Nutrient removal efficiency (NRE) for nitrogen and phosphorus increased significantly with the combined number of species. Species combinations also had a significant effect on feed efficiency ratio (FER). All observed parameters in scenario 3 (IAA) demonstrated superiority, making it a more practical approach for the IAA model in coastal zones. This study validates an optimal species combination model, providing a scalable framework to advance productivity and nutrient efficiency in future integrated coastal aquaculture systems.

Abstract

The nutritional potential of copepods as live feed for larvae warrants further exploration, particularly for juvenile and adult shrimp. However, their small size presents a challenge, as larger shrimp may struggle to capture such small prey. A nutrient-based formulation approach was adopted by supplementing Oithona sp. copepod meal into vannamei shrimp (Litopenaeus vannamei) feed, and its effects on survival and growth were evaluated. A 35-day experiment was conducted in aquariums (20×20×30 cm) with an 8-liter water volume. The experimental feed was prepared by coating it with copepod meal. Four supplementation levels, each with three replicates, were tested: 0, 1, 2, and 3 g per 100 g of feed. Vannamei shrimp with an initial weight of 2.15±0.03 g and a stocking density of 16 individuals per aquarium were fed three times a day to satiation. Although the differences were not statistically significant, the survival rate of shrimp fed with supplemented diets (all 100±0.00%) was higher than that of the non-supplemented group (97.9±3.6%). In terms of growth, Absolute Weight Gain (AWG) and Specific Growth Rate (SGR) were significantly higher in the 3 g (5.27±0.02 g and 3.53±0.01% day-1), 2 g (5.13±0.08 g and 3.51±0.06% day-1), and 1 g group (4.88±0.10 g and 3.36±0.07% day-1) compared to the non-supplemented group (2.97±0.13 g and 2.48±0.11% day-1). In conclusion, the supplementation of copepod meal effectively enhanced the survival and growth of vannamei shrimp. The 3 g dose is the best dose that promotes the highest growth and survival.

Abstract

Inorganic marine debris is a serious problem in coastal areas with high intensity of human activity. This study aims to characterize and measure the density of inorganic marine debris in the Tanjung Bunga area, Makassar City. Using a descriptive quantitative approach, the method applied was a 100 m line transect at three locations, namely station one residential area, station two gazebo area, and station three coastline. Data were collected in three repetitions covering the type, size and mass of debris, and supported by secondary oceanographic data (tides, currents, waves) from BMKG. The results showed that plastic was the most dominant type of debris (674 items), followed by wood (576), metal (354), styrofoam (202), rubber (170) and glass (94), with the largest mass recorded in plastic on the coastline, namely 10.95 kg. Based on size, macro debris dominated (61-67%), followed by meso (27-35%) and mega (4-6%). Oceanographic conditions reflect moderate-strong currents (19.2-43.6 cm/s), high waves between 0.28-0.40 meters, and a double daily tidal pattern, all of which influence waste distribution patterns. These findings confirm that plastic is a major threat to the coastal ecosystem in Tanjung Bunga (Jambeck et al., 2015; Suryawan, 2025), and serve as an important basis for formulating marine waste management policies and increasing public awareness.
