Abstract

Keberadaan kerang dengan karakteristik filter feeder diperlukan untuk memanfaatkan limbah akuakultur yang tersuspensi di kolom air sehingga dapat direduksi. Penelitian ini, kerang darah dari empat sistem akuakultur dievaluasi untuk menentukan laju filtrasi, yaitu sistem monokultur, polikultur, kokultur IMTA non-padi, dan kokultur IMTA padi. Kerang darah, ikan nila, dan udang windu masing-masing ditebar sebanyak 20 ekor pada 90 L air payau, sedangkan kepadatan teripang adalah 10 ekor. Untuk padi, dipelihara dengan metode terapung menggunakan nampan. Selama 4 minggu, pakan diberikan 4 kali sehari sebanyak 10% dari biomassa.  biota sangat menentukan keberhasilan budidaya multibiota pada sistem ko-kultur. Hasil analisis ragam menunjukkan bahwa kombinasi biota berpengaruh nyata (P<0,05) terhadap konsentrasi amoniak, nitrat, dan fosfat. Konsentrasi ketiga bahan organik di akhir penelitian pada sistem polikultur dan sistem IMTA secara signifikan lebih rendah dibandingkan pada sistem monokultur. Sementara itu, pengaruh kombinasi biota terhadap karakteristik morfometrik tidak menunjukkan pengaruh nyata (P>0,05). Laju filtrasi dan morfometrik akan efektif jika dikultur dengan spesies trofik level yang lengkap melalui sistem IMTA. The existence of mussels with filter feeder characteristics is needed to utilize aquaculture waste suspended in the water column so that it can be reduced. In this study, blood cockles from four aquaculture systems were evaluated to determine the filtration rate, namely monoculture, polyculture, non-rice IMTA coculture, and rice IMTA coculture. Blood clams, tilapia and tiger prawns were each stocked with 20 individuals in 90 L of brackish water, while the density of sea cucumbers was 10 individuals. For rice, it is maintained by the floating method using trays. For 4 weeks, the feed was given 4 times a day as much as 10% of the biomass. biota greatly determines the success of multibiota cultivation in co-culture systems. The results of the analysis of variance showed that the combination of biota had a significant effect (P<0.05) on the concentrations of ammonia, nitrate and phosphate. The concentrations of the three organic matter at the end of the study in the polyculture system and the IMTA system were significantly lower than in the monoculture system. Meanwhile, the effect of the combination of biota on the morphometric characteristics did not show a significant effect (P>0.05). Filtration rate and morphometrics will be effective if cultured with complete trophic level species through the IMTA system

Abstract

Fish farming activities in ponds produce waste in the form of feed residues and metabolic products such as urine and feces. To minimize the accumulation of these residual nutrients, an Integrated Multi-Trophic Aquaculture (IMTA) system is applied that combines organisms of different trophic levels: fed organisms (fish, shrimp), organic extractive organisms (sea cucumbers, shellfish, sea urchins), and inorganic extractive organisms (seaweed). This study aims to evaluate the influence of floating-bed-based integrated cultivation system on the survival and growth of kijing clams (Corbicula sp.). The experimental design used a Group Random Design (RAK) with nine units of experimental ponds at the People's Hatchery Unit (UPR) Sipurennu, Soppeng Regency, for 90 days. Three treatments were tested based on floating-bed moving time intervals: A (no displacement), B (10-day replacement), and C (20-day replacement). The main parameter observed was Absolute Weight Growth (PBM). The results showed that the highest PBM was found in treatment B (117.6 g), while the lowest was in treatment A (31.5 g). The ANOVA test showed significant differences between treatments (P<0.05), indicating that the frequency of displacement of extractive species affects the growth rate. In conclusion, the Integrated Agriculture-Aquaculture (IAA) system with a floating-bed model has a significant impact on the survival and growth of kijing mussels through the management of ecological utilization of aquaculture waste

Abstract

Integrated aquaculture or IMTA is a cultivation method that involves several communities with different trophic levels, in terms of the utilization of food sources (energy) in the waters. To determine the effect of species combinations on snapper growth in integrated cultivation of controlled recirculation system and To determine the effect of species combination on snapper survival in integrated cultivation of controlled recirculation system, the research method used was Complete Random Design (RAL) with 4 treatments and 3 replications and used ANOVA (Analysis Of Variance) data. The results showed that the survival of white snapper during 5 weeks of maintenance showed that the cultivation system had a significant effect on the ability of fish to survive, with the highest value in P4 treatment (IMTA) of 85.0% and lowest in P1 treatment (monoculture) of 43.80%, while P2 and P3 treatment reached 54.20% and 60.40% respectively. This pattern indicates that the integration of snapper with green shellfish and sea grapes in the IMTA system is able to create a more stable maintenance environment and support fish survival through the use of feed waste and feces as a source of nutrition for other organisms, thereby reducing the accumulation of toxic materials such as ammonia that have the potential to trigger stress and death. The results of ANOVA's analysis, which showed a significant influence of species combinations on synthesizers, as well as Tukey's follow-up tests, which confirmed the very real difference between P4 and other treatments, reinforced that integrated aquaculture approaches are more effective than monocultures or simple polycultures in improving the survival of white snapper in a closed recirculation system

Abstract

Increasing the productivity of aquaculture must be supported by feed input; however, in addition to being expensive, this input can produce nutrient waste. Therefore, finding inexpensive alternative forms of feed with environmentally friendly cultivation practices is important to do simultaneously. This study aimed to determine the effect of variations in the form of maggot feed on the Nutrient Reduction Efficiency (NRE) of freshwater clams (Pilsbryoconcha exilis) in an integrated multitrophic aquaculture (IMTA) system. This 28 day experiment used a Completely Randomized Design (CRD) with four types of feed treatments (live maggots, dried maggots, supplemented maggots, and commercial feed (control). A total of 10 individuals of freshwater clams combined with 10 tilapia fish and freshwater lobsters respectively, as well as 4 clumps of rice were floated in a rearing tank with a volume of 50 L of fresh water. The results of analysis of variance showed that variation in feed had a significant effect (P<0.05) on the NRE of ammonia (NH3), nitrate (NO3), phosphate (PO4) by freshwater clams (Pilsbryoconcha exilis). Tukey HSD test results indicated that the highest NRE of ammonia (NH3) in live maggots feed was significantly different (P<0.05) from dried maggot feed and supplemented maggots, but not significantly different (P>0.05) from commercial feed. NRE nitrate (NO3) was significantly different in each treatment. Meanwhile, the highest NRE phosphate (PO4) in live maggots feed was not significantly different (P>0.05) from dried maggots, but was significantly different (P<0.05) from supplemented maggots and commercial feed.

Abstract

Glossogobius matanensis is one of the endemic fish species found only in Lake Towuti, South Sulawesi. Its limited population and environmental pressures make it necessary to conserve efforts through a domestication approach. This study aims to analyze the condition factor of G. matanensis fish as an indicator of health and biological readiness in the context of domestication. Sampling was carried out at several points in the waters of Lake Towuti using the purposive sampling method. The observed parameters included total length, body weight, and condition factor (K) which were calculated using the King formula. The results showed that the value of the condition factor ranged from 1.00–1.05 which indicated that the fish was in good physiological condition. The variation in K-values also reflects differences in habitat quality and availability of natural feed in each location. These findings provide an important basis for the development of early aquaculture technologies and support long-term conservation programs for this endemic species. The domestication of G. matanensis is seen as an adaptive strategy to maintain the sustainability of local genetic resources amid changes in the ecosystem of Lake Towuti

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 compared the Feed Conversion Ratio (FCR) of Nile tilapia (Oreochromis niloticus) and African catfish (Clarias sp.) cultured in a maggot-based aquaponic system. The experiment was conducted from March to May 2025 using a completely experimental approach with two treatments and three replications. Nile tilapia and African catfish were fed dried Black Soldier Fly (Hermetia illucens) larvae as the sole protein source, while mustard greens were cultivated as the plant component of the aquaponic system. Feed utilization efficiency was evaluated using Feed Conversion Ratio (FCR), and differences between treatments were analyzed using an independent-samples t-test. The results demonstrated that Nile tilapia exhibited a significantly lower FCR (0.41) than African catfish (0.70), indicating superior feed utilization efficiency. Statistical analysis confirmed a significant difference between the two treatments (p = 0.037), suggesting that fish species significantly influenced the efficiency of maggot utilization under identical aquaponic conditions. The lower FCR observed in Nile tilapia was attributed to its omnivorous feeding behavior, greater digestive adaptability to insect-based diets, and better compatibility with the nutrient recycling processes occurring within the aquaponic system. Overall, the findings indicate that integrating Black Soldier Fly larvae with aquaponic technology can substantially improve feed efficiency while reducing production costs and nutrient waste. Nile tilapia demonstrated greater suitability than African catfish for sustainable maggot-based aquaponic production systems.

Abstract

Integrated Multi-Trophic Aquaculture (IMTA) has emerged as an environmentally sustainable aquaculture approach by integrating organisms from different trophic levels to improve nutrient recycling efficiency. This study evaluated the effectiveness of various IMTA species combinations in reducing Total Ammonia Nitrogen (TAN), Dissolved Inorganic Nitrogen (DIN), and Dissolved Inorganic Phosphate (DIP) within marine culture systems. A completely randomized design with four treatments and three replications was employed, comprising P1 (Lates calcarifer), P2 (Lates calcarifer + Perna viridis), P3 (Lates calcarifer + Caulerpa lentillifera), and P4 (Lates calcarifer + Perna viridis + Caulerpa lentillifera). Water samples were collected every 15 days over a 45-day culture period and analyzed using UV–Visible spectrophotometry. Nutrient reduction efficiency was calculated for each treatment, while one-way Analysis of Variance (ANOVA) followed by Tukey's post hoc test was applied to determine significant differences among treatments. The results demonstrated that integrated culture systems consistently reduced nutrient accumulation more effectively than monoculture. The complete IMTA treatment (P4) exhibited the greatest capacity to regulate TAN, DIN, and DIP concentrations through complementary nutrient uptake by macroalgae and filtration by bivalves. ANOVA confirmed significant treatment effects on TAN (F = 6.24, p = 0.021), DIN (F = 5.87, p = 0.016), and DIP (F = 5.21, p = 0.021). These findings demonstrate that integrating Lates calcarifer, Perna viridis, and Caulerpa lentillifera substantially enhances nutrient recycling efficiency, improves water quality, and provides an ecologically sustainable strategy for tropical marine aquaculture.

Abstract

Yellow-finned medaka fish (Oryzias profundicola) is an endemic species in Lake Towuti and is often consumed by people around the lake. Despite the potential of this species, the problem of over-exploitation has led to a significant decrease in its population. Therefore, this study aims to analyze the sex ratio, first gonad maturity size, and egg diameter of yellow-finned medaka from Lake Towuti. Fish samples were caught using seser nets, and data were collected from January to June 2022 at stations located in Tanjung Timbala, Tanjung Lengkobutanga, Tanjung Bakara, Tanjung Saone, and Tanjung Tominanga. The sex of each fish was identified through the examination of body morphology and gonad. Measurement of egg diameter was carried out at gonad maturity levels III and IV, and a total of 200 eggs were observed at each station per month. The total length and total weight of samples were then measured. Data on sex ratio, size at first gonad maturity, and egg diameter were analyzed using several equations. The results showed that the sex ratio of yellow-finned medaka in Lake Towuti was balanced. The average size range at first gonad maturity of male and female fish was 32.65-39.96 mm and 25.82-33.08 mm, respectively. In addition, the frequency distribution of egg diameter showed peak mode at gonad maturity levels III (0.03-0.17 mm) and IV (0.93-1.07 mm). Based on these findings, yellow-finned medaka was included in the partial or long spawning categories. The results of this study were expected to provide information on the sustainable management, conservation, and domestication of yellow-finned medaka.
