Abstract

The plant species mangrove has been knowed to be effective for the bio-desalination process. However, there is currently no scientific evidence supporting the ability of mangrove bio-desalination when implemented through the floating method. This laboratory-scale study aimed to evaluate the bio-desalination of several mangrove species using the floating method. This study consisted of four treatments and three replicates. Treatments included a control group without mangroves (treatment A) and three treatments using mangroves (treatments B, C, and D), Bruguiera sp., Rhizophora sp., and Avicennia sp., which were positioned floating in a tank using a tray. During the eight weeks of rearing, nutrients were provided through 60 mL liquid NPK fertilization. The results showed that there was a decrease in salinity concentration in all mangrove treatments between 22.5-23.9 ppt from the initial salinity of 30 ppt. Different results were observed for the treatment without mangroves, and the salinity concentration tended to increase until the end of the research to 31.6 ppt. The highest Salinity Reduction Efficiency (SRE) was achieved by Avicennia sp.. (25.1%), followed by Rhizophora sp. (22.8%), and the lowest in Bruguiera sp. (20.3%). The results of this study showed that bio-desalination using mangroves had a significant effect on SRE, and each treatment indicated a significant difference (p<0.05). The results of this study provide initial evidence of the potential of the mangrove floating method for bio-desalination of seawater into brackish water.

Abstract

The plant species of miana (Coleus scutellariodes) has been historically recognised for its antiviral properties.  However, there is currently no scientific evidence supporting the efficacy of miana leaf extract in preventing White Spot Syndrome Virus (WSSV) in tiger prawns (Penaeus monodon) when administered via feed. This study aimed to determine the impact of including miana leaf extract in the diet on the  survival percentage of tiger prawns that have been infected with the WSSV. The study was carried out between June and August 2023 in the Laboratory of Parasite and Fish Disease and the Hatchery Laboratory of Hasanuddin University. This study employed a completely randomized experimental design consisting of five distinct treatments, each with three replicates. The experimental treatments included the control group (treatment A), where food was provided without the inclusion of miana leaf extract. Furthermore, there were four treatment groups (treatments B, C, D and E) where feed was supplemented with miana leaf extract at concentrations of 125, 250, 500, and 750 µg mg-1 feed, respectively. Rearing was performed in two phases: preinfection (25 days) and post- infection (7 days). The statistical results of the statistical on pre-WSSV infection indicated that the addition of miana leaf extract to the food resulted in survival that was not significantly different (p>0.05). The results were different post-infection, significantly (p<0.05) the shrimp fed with the addition of miana leaf extract were higher than those without the extract. Furthermore, there was a significant difference in shrimp survival between pre- and post-WSSV infection. WSSV mitigation through immunostimulants using miana leaf extract, which is inexpensive and environmentally friendly, has the potential to minimize the impact of WSSV infection.

Abstract

Many aquaculture wastes are suspended in the water column in that the presence of clams as filter feeders is required to utilize the waste for growth. In this study, blood clams from four aquaculture systems were evaluated to determine their growth, namely monoculture systems, polycultures, Integrated Multi Trophic Aquaculture (IMTA) non-paddy cocultures, and IMTA with paddy cocultures. Blood clams, tilapia, and tiger shrimp are stocked at as much as 20 each in 90 L of brackish water, whereas the density of sea cucumbers is 10 individuals. For paddy, reared using a floating method that uses trays. For four weeks, feed was given four times a day as much as 10% of the biomass. The results showed that the aquaculture system were a significant effect (P<0.05) on Spesific Growth Rate (SGR). The SGR of blood clams when combined with the IMTA systems were significantly higher (P<0.05) than that of the monoculture and polyculture systems. In contrast to growth, morphometric characteristics were not significantly affected (P>0.05) by aquaculture system. Apart from studies in laboratory scale, the highest growth of blood clams is obtained if cultured with complete trophic levels through the IMTA paddy system.

Abstract

Amonia (NH3-N) adalah nitrogen terlarut yang paling berbahaya dari limbah akuakultur. Sebuah eksperimen telah dilakukan untuk mengevaluasi sistem kokultur yang efisien dalam mereduksi NH3-N. Sebanyak 4 spesies hewan akuaktik, yaitu ikan nila (Oreochromis niloticus), udang windu (Penaeus monodon), kerang darah (Tegillarca granosa), dan teripang pasir (Holothuria scabra), serta tanaman padi (Oryza sativa) dikombinasikan pada beberapa sistem akuakultur. Enam perlakuan dan masing-masing dengan tiga ulangan dirancang menggunakan rancangan acak lengkap (RAL). Benih hewan akuatik diaklimatisasi secara bertahap selama 30 hari. Benih padi disemai di air payau, selanjutnya ditebar menggunakan metode apung. Selama 28 hari eksperimen, ikan nila dan udang windu diberi pakan 4 kali sehari dengan feeding rate sebesar 10% bobot biomas, sedangkan kerang darah dan teripang pasar tidak diberikan pakan. Hasil menunjukkan bahwa efisiensi reduksi nutrien (ERN) NH3-N di dua sistem monokultur bernilai negatif, sementara empat sistem kokultur bernilai positif. Nilai ERN dua perlakuan sistem polikultur tidak berbeda (P>0,05). Sementara itu, nilai ERN pada sistem IMTA lebih tinggi dari sistem monokultur maupun polikultur (P<0,05). Temuan ini mengarah pada pemanfaatan keanekaragaman spesies untuk akuakultur berkelanjutan di air payau. Hal ini dapat disimpulkan bahwa sistem akuakultur yang paling efisien dalam mereduksi NH3-N adalah sistem IMTA-padi dengan nilai ERN sebesar 43,3±1,7%. Nilai ini lebih tinggi (P<0,05) dari semua sistem akuakultur lainnya

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).
