Abstract

Probiotics application in aquaculture sector has been promoted since the government has banned antibiotics application in aquaculture sector. Probiotics are very useful in aquaculture because it can accelerate fish growth, improve fish health, and maintain water quality in good condition. However, there are many fish farmers who do not know the advantages, manufacturing techniques and the application of probiotics to support aquaculture activities. Therefore, we have conducted this community service for fish farmers in Meunasah Sukon Village, Lembah Sabil District, Southwest Aceh Regency. This community service is carried out through counseling by describing the benefits of probiotics, followed by discussions with participants and probiotics practice using natural ingredients that are easily available. The result showed that the level of understanding and knowledge of fish farmers in this village about the benefits of probiotics, how to manufacture and its application were increases after this community service was conducted. The activities of enhancement fish farmer capacities are needed to improve their abilities about information on aquaculture renewable technology.

Abstract

Minapadi is a fish rearing system in rice fields that is carried out with rice plants. This study aims to increase the income of farmers with high productivity of rice yields and increase the production of giant prawns. The method used is a Completely Randomized Design (CRD) experiment with 3 treatments and 3 replications. The treatments were: P1 = stocking density of 100 birds/plot, P2 = stocking density of 200 birds/plot, P3 = stocking density of 300 birds/plot. This research was conducted for 90 days. Parameters observed were rice productivity and growth. The results showed that the best treatment was P2 = stocking density of 200 birds/plot. by producing an average value of rice productivity of 5 kg/50 m2 and an average value of growth of giant prawns of 4.72%.

Abstract

Minapadi is a fish rearing system in rice fields that is carried out with rice plants. This study aims to increase the income of farmers with high productivity of rice yields and increase the production of endemic fish. The method used is a Completely Randomized Design (CRD) experiment with 4 treatments and 3 replications. The treatments were: A1B1 (legowo 2:1 and giant prawns), A1B2 (legowo 2:1 and fish exclamation), A2B1 (legowo 4:1 and giant prawns), and A2B2 (legowo 4:1 and fish exclamation). This research was conducted for 90 days in the rice fields of Lango Village, Pante Ceureumen District, West Aceh Regency. Parameters observed were rice productivity, fish growth and business analysis. The results showed that the best treatment was A1B1 (legowo 4: 1 and giant prawns) by producing an average value of rice productivity of 5 kg/plot, and the average value of growth of giant prawns of 3.62 g/head and fish of fish of 37.17 g/head. From the results of this study, the application of the Minapadi system with giant prawns and fish with legowo 4:1 gave a positive impact on the observed parameters (P<0.05) and provided benefits for farmers.

Abstract

This study aims to determine the effect of administration of activated charcoal, zeolite, and manganese greensand on survival Oreochromis niloticus. The experimental design used was a completely randomized design (CRD) with 4 treatments and 3 repetitions. The treatments are P1 = without administration (control), P2 = administration of activated charcoal 10 gr/l P3 = administration of Zeolite 10 gr/l and P4 = administration of manganese 10 gr/l. The parameter observed in this study was survival Oreochromis niloticus. The results showed that administration of activated charcoal, zeolites, and manganese greensand significantly affected the survival of Oreochromis niloticus. The best value is obtained at treatment P1; P2; and P3, each with the best average survival value of 96%; 91%; and 91%. The lowest cost incurred is the treatment P1 Rp. 66.200, - with SR 96% transportation.

Abstract

This research aims to know the level of fertilization and hatching rate of tawes fish eggs (Puntius javanicus) after cryopreservation sperm in temperature 4oC. This research has been carried out in the mini laboratory (Meunasah Krueng Village of Beutong Subdistrict Nagan Raya Regency) on 19-20 August 2015. This research is both experimental, using a complete Randomized Design with 5 treatments and 3 replicates. Sperm that is used is the result of storage with the dilution of physiological NaCl and green coconuts water including P1 0% NaCl only, P2 3%, P3 5%, P4 7% and P5 9%. The results showed that the addition of green coconut water on sperm storage provides a real effect against fertilization and hatching rate of tawes fish eggs (p < 0.05). The highest levels of fertilization found in the treatment of P4 (64.3%, 0.7 mL of diluent in green coconut water + physiological NaCl solution), while the lowest fertilization found on P1 registration (25%, physiological NaCl solution). For the level of hatching rate, the highest value is found in the treatment of P4 (61.7%), and the lowest is present on the P1 registration (14.3%).

Abstract

Fishing of mud crab (Scylla sp.) is using many fishing gear type, one of that i.e traps. Immersion periods is one of aspect to consideration to catching mud crab. Therefore, purpose of this study is to know immersion periods to catching mud crab efectively. This study was conducted on September 2016 in estuaries waters, Kuala Bubon Village, Samatiga  Sub District, Aceh Barat District. Methods of this  study is experimental fishing method and fully randomized design have used for this study. Immersion periods is treatments, i.e 4 hours, 8 hours and 12 hours with  3 replicates. An analysis of variance (ANOVA) at significant level 95% (p < 0.05) was selected to assess the statistical significance of the treatment differences. All data was performed with SPSS 18.0.0 software. Results of this study show that fish catching of mud crabs not siggnificant difference for every treatments (p>0.05). However, descriptive analysis show that immersing with 12 hours more efective than of 4 hours and 8 hours. This study is important for traps’s fishermen to catching mud crabs, where hauling of traps can be applied in the morning (immersing with 12 hours).

Abstract

Snakehead (Channa sp.) was one of the superior freshwater fish species native to Indonesia that has been successfully domesticated. The increasing demand for snakehead fish on the market has resulted in the addition of cultivated land and water use. Aquaponics technology was a combination of fish farming and plants that grow without soil media. The aim of this research was to determine the best composition of probiotics that can be used in aquaponic technology to optimize growth rate and feed conversion of snakehead fish (Channa sp.). This research used an experimental method. The experimental design used was a completely randomized design with four probiotic combination treatments and each treatment was repeated three times. The results showed that awarding of different probiotic compositions in the aquaponic system resulted in a spesific growth rate that was not significantly (P>0.05) different between treatments. The highest value of spesific growth rate were in the treatment of probiotic composition of Lactobacillus casei and Saccharomyces cerevisiae with a value of 4.11%/ day. Awarding of different probiotic compositions in the aquaponic system results in significantly (P<0.05) different feed conversion ratio values. The best feed conversion ratio values were in the treatment of probiotic composition of Lactobacillus casei and Saccharomyces cerevisiae with a value of 1.78. The conclusion of this study was the composition of probiotic Lactobacillus casei and Saccharomyces cerevisiae was the best probiotic composition to increase the spesific growth rate and feed conversion ratio of snakehead fish.

Abstract

This study aimed to determine feeding habits layur fish and composition of food eaten by layur. The study was conducted in september to october 2016. The method used in this research is survey method. The result showed that the types food of layur are small shrimp with a percentage value of 35%, then a small fish with a value of 17% and pulverized fish with a value of 48%. Frequency of occurrence type food obtained is 44% pulverized fish, small shrimp 37% and the lowest percentage of appearance food is small fish by 19%. IP value of small shrimp at 35% and the lowest part small fish by 9%, and then RLG of layur acquired intestinal length relative 0.91, intestinal length 32 and total length of 35 cm. Based on the value of RLG is less than 1, then the layur (Lepturacanthus savala) is a carnivorous (carnivores).
