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 practical application of waste recycling as feed supplement is potentially required by small-scale aquaculturist. Furthermore, some of the flour derived from waste sea urchin shells and in adopted in feed, including Deadema setosum were evaluated to estimate the effect on white shrimp Litopenaeus vannamei moulting. This research required the experimentation of four doses with triplicate supplementation (0, 2, 4, and 6 g 100 g-1 of feed) on shrimps four times daily (12% of body weight) for 35 days test period. The juvenile specimens, characterized by an initial weight of 1.610.11 g, were stocked at a density of 12 individuals in a 12 L aquarium. In addition, four compartments were created in each aquarium to facilitate progress observations. The proximate analysis results showed a 53.760.27% calcium content in the shell flour, which significantly increased (P0.05) after higher dose supplementation, in the sequential order 18.650.13%, 20.040.08%, 23.180.10%, and 25.040.11%. Moreover, the frequency and moulting interval with 4 g doses (16.59%0.36% day-1 and 5.910.18 days-1) were significant (P0.05) and considered the best, compared to 0 g (10.48% 0.24% day-1 and 9.970.37 days-1), 2 g (13.49%0.96% day-1 and 8.100.29 days-1), and 6 g (13.81%0.24% day-1 and 7.900.06 days-1). In addition, the respective trend pattern for both parameters increased and decreased at 4 g and 6 g, correspondingly. The highest moulting intensity was also obtained with the 4 g doses, at a range of 4 to 6 times, while the lowest (0 g) varied from 3 to 4 times. These sea urchin shell flour was determined to have numerous practical applications as a feed supplement with proven ability to stimulate moulting in vannamei shrimp.Keywords:MoultingCalciumShellSea urchinFeed supplementationVannamei shrimp

Abstract

Optimizing species combinations is essential for enhancing the Integrated Multi-Trophic Aquaculture (IMTA) system for milkfish, especially in brackish water involving paddy plants. This research examines the percentage weight gain (PWG), daily weight gain (DWG), profitability, and benefit-cost (B/C) ratio of milkfish farming within the IMTA-Paddy system using three treatments with three replication: T1 (milkfish and paddy), T2 (milkfish, tiger prawns, and paddy), and T3 (milkfish, tiger prawns, mussels, and paddy) within a completely randomized design model. Thirty individuals of each aquatic species were stocked per tarpaulin pond along with 30 clumps of floating paddy. Milkfish were fed commercial feed three times daily over 80 days. Results showed that T3 had significantly higher body weight gain (BWG: 796.43%) and daily weight gain (DWG: 1.23 g/day) than T2 and T1. T3 also yielded the highest profit (IDR 89,483/kg) and benefit-cost ratio (BCR: 1.61), significantly outperforming T2 and T1. The inclusion of mussels, acting as an organic extractive species, contributed notably to the improved growth and economic performance of milkfish in T3. These findings underscore the importance of well-designed species integration in improving aquaculture productivity and sustainability, and provide a promising foundation for scaling up IMTA-Padi systems in brackish coastal areas of Indonesia.

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

Information on morphometrics has been widely used for catches. This study aims to determine the morphometric characteristics of rabbitfish in a multi-trophic system cultivation based on feeding rate. Rabbitfish are maintained in an integrated manner with green mussels, sea urchins, and seaweed. The study was conducted for 6 weeks at the Laboratory of the Balik Diwa Maritime Technology and Business Institute, Makassar. Three feeding rate treatments of 5%, 7.5%, and 10% each with three replications were given to rabbitfish with a frequency of 4 times a day. During maintenance, a closed water circulation process was carried out and continuous aeration was provided in each container. The results showed that the total length at feeding rates of 5%, 7.5%, and 10% were 5.3 cm, 7.1 cm, 8.1 cm, respectively, and the standard length was 4.1 cm, 5.8 cm, and 6.7 cm, respectively. Meanwhile, the height of each body was 1.8 cm, 2.1 cm, and 2.6 cm. Analysis of variance showed that these three morphometric variables were significantly affected by feeding rate, and the three levels of feeding rate were significantly different (P<0.05). Water quality during maintenance was in the range that could be tolerated by rabbitfish. Temperature was in the range of 26.0-28.6°C, salinity 25.1-28.5 ppt, dissolved oxygen 5.2-7.1 mg/L, pH 7.6-8.0 and ammonia 0.032-0.095 mg/L. The morphometric characteristics of rabbitfish in multi-trophic system cultivation increased significantly along with the increase in feeding rate.

Abstract

Freshwater lobster (Cherax quadricarinatus) is a type of crustacean that has relatively fast growth, relatively easy reproduction and handling, is omnivorous and has a morphology similar to sea lobster so that it is in demand by consumers. This study aims to determine the effect of the use of a combination of earthworms and cassava feed on the growth and number of freshwater lobster moulting. The research method used is a Completely Randomized Design (CRD) with five treatments and three replications. Treatment A = 100% earthworms, B = 100% cassava, C = 75% earthworms + 25% cassava, D = 50% earthworms + 50% cassava, D = 25% earthworms + 75% cassava. The results of the study showed that the highest average Absolute Weight Gain (PBM) was obtained in treatment B (2.33 g), followed by treatment D (1.95 g), followed by treatment A (1.85 g), followed by treatment E (1.84) and the lowest in treatment C (1.76 g). The highest average Specific Growth Rate (SGR) was obtained in treatment B feed (4.09%), followed by treatment D (3.83%), followed by treatment A (3.77%), followed by treatment C (3.69%) and the lowest in treatment E (3.60%). The highest Absolute Length Gain (PPM) was obtained in feed B (1.87 cm), followed by treatment A & E feed (1.84 cm), followed by treatment D feed (1.82 cm) and the lowest in treatment C feed (1.78 cm). Survival between consecutive treatments (A=83.33%, B=90%, C=80%, D=80%, E=83.33%). The number of moulting between consecutive treatments (A=9.33%, B=10%, C=9%, D=8.33%, E=8%). The results of the analysis of variance showed that the combination of feed had no significant effect (P>0.05) on PBM, LPS and PPM of freshwater lobsters.

Abstract

This study aims to examine the effect of fermented maggot feeding on the survival and growth of tilapia (Oreochromis niloticus) as an effort to increase feed efficiency in fish farming. Maggots are known as an alternative feed source rich in protein, but the fermentation process is needed to increase the digestibility and availability of nutrients. This study was conducted for six weeks at the Moncongloe Aquaculture Institute using an experimental trial method with a Completely Randomized Design (CRD) consisting of four treatments, namely A (maggots without fermentation as a control), B (maggots fermented with SLS), C (maggots fermented with EM4), and D (maggots fermented with Yakult), with each treatment being repeated three times. The main parameters measured included survival and absolute weight growth of tilapia. Based on the results of the study, the highest survival data was obtained in treatment B with a value of 86.7%, followed by treatments C and D which were each 83.3%, and treatment A (control) of 73.3%. Meanwhile, the absolute weight growth parameter showed the highest value in treatment B at 5.92 g, followed by treatment C at 5.79 g, treatment D at 5.58 g, and treatment A at 5.29 g. The results of the analysis of variance (ANOVA) revealed that the provision of fermented maggot feed did not have a significant effect on the survival of tilapia, but had a significant effect on its absolute weight growth. The treatment of maggot fermented with SLS (treatment B) showed superior results compared to other treatments, indicating that certain types of fermentation can increase the effectiveness of feed in supporting the growth of tilapia. Thus, this study provides scientific evidence that maggot fermentation, especially using SLS, is a potential method to improve the quality of fish feed, so that it can be applied as an innovation in the development of more efficient and sustainable fish farming

Abstract

Maggot is one of the local ingredients that has many benefits and many properties. Maggot is one of the feeds that is easy to make using organic waste. Fermentation is one of the applications of microbes in an effort to improve the quality of feed raw materials. The purpose of this study was to determine the effect of fermentation materials on the efficiency of tilapia (Oreochromis niloticus) feed and to determine the effect of fermented feed on digestibility in tilapia (Oreochromis niloticus). The method used in this study was experimental, where the experimental treatments were the types of feed and fermentation materials consisting of 4 combinations with 3 repetitions each, namely A (100% Maggot feed), B (Maggot 100 g fermented with 20 mL nano enzyme). C (Maggot 100 g multivariant fermentation 20 ml), D (Maggot 100 g fermented with 20 ml Lactobacillus). This research was conducted from May to July 2024 at the Moncongloe Maros Aquaculture Institute Laboratory. The results of the study showed that the highest feed utilization efficiency was in treatment B (SLS) with a value of 43.79%, followed by treatment D (yakult) with a value of 42.83% followed by treatment C (Em4) with a value of 42.38% and the lowest feed efficiency was in control treatment A (Maggot) of 34.46. Furthermore, maggot feed fermentation also had a significant effect (P <0.05) on the protein efficiency ratio in tilapia (Orerochromis niloticus).

Abstract

Hospital wastewater contains a complex mixture of organic pollutants, suspended solids, pathogenic microorganisms, pharmaceutical residues, and hazardous substances that may threaten environmental quality and public health if discharged without adequate treatment. This study aimed to evaluate the performance of the wastewater treatment plant (WWTP) at Hasanuddin University Hospital, Makassar, Indonesia, by assessing the quality of treated wastewater based on selected physicochemical and microbiological parameters. A quantitative descriptive approach was employed through direct sampling at the WWTP between November 2025 and January 2026. Grab sampling was conducted at the influent and effluent points, while laboratory analyses measured total suspended solids (TSS), biochemical oxygen demand (BOD), chemical oxygen demand (COD), pH, cadmium (Cd), and total coliform following APHA standard methods. The results demonstrated that the WWTP effectively reduced pollutant concentrations, with removal efficiencies of 96.36% for TSS, 81.58% for BOD, 83.71% for COD, 66.67% for Cd, and 99.35% for total coliform. The effluent pH remained stable within the neutral range, supporting effective biological treatment and compliance with environmental quality standards. These findings indicate that the integrated physical, biological, and chemical treatment processes operated efficiently in reducing pollutant loads before wastewater discharge. Continuous operational monitoring, routine maintenance, and optimization of treatment processes are recommended to ensure long-term treatment performance and support environmentally sustainable hospital wastewater management.

Abstract

The aquaponics system is an alternative solution that can utilize waste from cultivation while saving land and water use. One common obstacle in tilapia and catfish cultivation is the use of artificial feed which is quite expensive from an economic point of view and produces large amounts of waste, which can degrade water quality. This study aims to compare water quality in tilapia and catfish cultivation in an aquaponics system using maggot-based feed. The study was conducted from March to May 2025, located in Mandalle Village, Mandalle District, Pangkep Regency, and at the Pangkep State Agricultural Polytechnic Laboratory. The study was designed on a field laboratory scale with two treatments, each replicated three times. Data were analyzed using an independent t-test with a 95% confidence level. The results showed that NH3 levels at the beginning of treatment A: 0.003 mg/L and B: 0.002 mg/L, in the middle A: 0.124 mg/L and B: 0.102 mg/L, and at the end of treatment A: 0.065 mg/L. Meanwhile, the NO3 levels at the beginning of treatment were A and B: 0.001 mg/L, mid A: 0.080 mg/L and B: 0.044 mg/L, and end A: 0.051 mg/L and B: 0.044 mg/L. For PO4, the results were initial A and B: 0.002 mg/L, mid A: 0.048 mg/L and B: 0.015 mg/L, and end A: 0.051 mg/L and B: 0.022 mg/L. Aquaponic system with maggot feed provides a significant difference in phosphate levels, but does not show a significant difference in ammonia and nitrate levels.
