Abstract

The purpose of this study was to examine the effect of fish silages, bakasang as an immunostimulant in eel (Anguilla marmorata) feed against Aeromonas hydrophila infection. Three hundred elvers with the size of + 10 cm taken from Freshwater Aquaculture Institute (BBAT) Tatelu. The elvers were placed into 4 glass aquarium, each equipped with aerator and 1 for stock. Prior to the study, the eels were acclimatized for two weeks in order to adapt to new environmental condition. Two sets of researches were done: feeding the eels with additional bakasang with different doses for 6 weeks, which then further were challenged with Aeromonas hydrophila by immersion method. This study used a completely randomized design (CRD) with 4 treatments A (0 mL /kg diet), B (50 mL/kg diet), C (100 mL/kg diet), D (150 mL/kg diet). The growth data was taken by measuring the weight and length of the eels at the end of the period of feeding treatment while the mortality data of the eels were observed for 10 days after challenge test.  The results of analysis of variance showed that the resistance of the eels in treatment B (50 mL/kg diet), C (100 mL/kg diet) and D (150 mL/kg diet) significantly different compared with treatment A.  However, among the treatments B, C and D, there were no significant differences.  Furthermore, the best eel growth was observed in treatment B with an absolute growth of 1.14 g, followed by treatment of D with an absolute growth of 1.04 g. In treatment A the absolute growth was only 0.82 g while treatment C was 0. 88 g.  This suggests that the addition of bakasang in eels feed can promote the growth of eels as well as resistance against pathogen infection, thus served as immunostimulant.

Abstract

Southeast Minahasa Regency has potential natural resources, one of them related aquculture in Lake Tutud. Considering the conditions and opportunities for the development of aquaculture in Lake Tutud, improvement efforts and increase the potential for fish production needs to be done. Some of the factors that caused the current problems include declining water level of Lake Tutud drastically in recent years caused by the death of most of spring water coming into the lake causing sedimentation, high content of sulfur from the irrigation run off. All of these problems can be a barrier to tilapia fish culture, so it is necessary to periodically measure the water quality in Lake Tutud in order to improve and enhance the quality of the water before it is used for culture efforts. Referring to the current economic conditions of the community around Lake Tutud of Tombatu 3 Village include community leaders and the fish farmers are also public observers who are interested in this program, through the Program Implementation of science and technology for the Community (IbM) of PNBP UNSRAT given counseling, training and mentoring such as water quality management technology. The methods used in the implementation of science and technology program are education, training, discussion and mentoring. Materials used were proper method of producing fish seeds, the stages of the production process, the use immunostimulatory in fish feed for fish disease management, maintain and improve water quality. With the Community Service Program through the application of science and technology, it is expected that there will be a transferred in science and technology in water quality management of Tutud lake so hopefully their business development, creation of business opportunity, income generation and welfare of the people in this Tombatu 3 village. The results revealed that the implementation of this community service activity in the form of the application of science and technology are: lecture activities, training, discussion and question and answer, including the lake water quality measurements that have been going well with good response of the fish farmers indicated by the presence of participants as much as 80%, show that a). increased production of tilapia fish farmers through water quality management can be implemented, b). tilapia fish farming is feasible and can provide profit if done properly, so it can be an alternative in an effort to help the reduction of unemployment and poverty. Interaction with the community on this community service activity, it is found that there were many people who still do not understand much about the overall material included engineering, water quality management and proper fish feed and feeding method. One of the barriers was the language, so it is necessary for the lectures and trainers to use the local language. It can be recommended in the future to keep on doing this kind of community service considering the inherent of the knowledge and application of water quality management is still a new thing and has a business prospective opportunities in the Tombatu 3 village. Keywords: water quality, community, management. Abstrak Kabupaten Minahasa Tenggara mempunyai potensi sumber daya alam yang banyak salah satunya yang berkaitan dengan bidang Perikanan budi daya air tawar adalah Danau Tutud. Memperhatikan kondisi dan peluang pengembangan pembudidayaan ikan di Danau Tutud maka upaya perbaikan dan peningkatan potensi produksi ikan perlu dilakukan. Budi daya ikan khususnya di Danau Tutud adalah pembudidayaan pembesaran ikan nila di Keramba Jaring Tanjap (KJT). Dalam usaha pengembangan budi daya ikan air tawar harus diimbangi dengan pengelolaan kualitas air danau dan penanganan penyakit ikan yang baik. Oleh sebab itu aspek-aspek yang menjadi factor pembatas dalam hal peningkatan produksi perlu dicari jalan keluarnya yang baik. Beberapa faktor yang menjadi masalah yang dihadapi saat ini antara lain adalah menyusutnya secara drastis permukaan air Danau Tutud dalam beberapa tahun belakangan ini akibat dari matinya sebagian besar mata air yang masuk ke danau sehingga mengalami sedimentasi, selain itu kandungan sulfur atau belerang cukup tinggi dari air irigasi yang berasal dari danau yang mana akan dapat menjadi hambatan usaha pembenihan ikan nila, sehinggan diperlukan adanya pengukuran kualitas air Danau Tutud untuk dapat memperbaiki dan meningkatkan kualitas air sebelum dipergunakan untuk usaha budi daya. Mengacu pada kondisi tersebut maka untuk masyarakat sekitar Danau Tutud di Desa Tombatu 3 antara lain para tokoh masyarakat dan para pembudidaya ikan juga masyarakat pemerhati yang tertarik pada program ini, melalui Program Penerapan Ipteks bagi Masyarakat (IbM) dari PNBP UNSRAT diberikan penyuluhan, pelatihan dan pendampingan berupa teknologi pengelolaan kualitas air. Metode yang digunakan dalam Program Penerapan Ipteks ini adalah penyuluhan, pelatihan, diskusi dan pendampingan. Materi kegiatan pengabdian penerapan Ipteks ini meliputi cara memproduksi benih ikan yang benar dan baik, tahapan-tahapan proses produksi pakan ikan yang diberi imunostimulan untuk penanganan penyakit ikan, tahapan tahapan untuk memelihara dan meningkatkan kualitas air. Dengan Program Pengabdian Kepada Masyarakat melalui penerapan Ipteks ini diharapkan dapat ditransfer ilmu dan teknologi pengelolaan kualitas air Danau Tutud sehingga diharapkan adanya pengembangan usaha, penciptaan peluang berusaha, peningkatan pendapatan dan kesejahteraan masyarakat di Desa Tombatu 3 ini. Hasil pelaksanaan kegiatan pengabdian kepada masyarakat dalam bentuk penerapan ipteks ini adalah: kegiatan ceramah, pelatihan, diskusi dan tanya jawab, termasuk dengan pengukuran kualitas air Danau Tutud telah berjalan dengan baik respon kehadiran peserta sebanyak 80%. Dari hasil pelatihan, diskusi tanya jawab dan prakek dilapangan menunjukkan bahwa a). peningkatan produksi pembudidaya ikan nila melalui pengelolaan kualitas air ini dapat dilaksanakan, b). pembudidayaan ikan nila ini layak dan dapat memberikan profit bila dilaksanakan dengan baik dan benar, sehingga dapat menjadi alternatif lapangan usaha baru untuk membantu program pengentasan penggangguran dan penanggulangan kemiskinan. Dari hasil interaksi dengan masyarakat pada kegiatan pengabdian ini diketahui bahwa banyak masyarakat yang masih belum banyak mengerti tentang keseluruhan materi termasuk pada materi teknik dan proses pengelolaan kualitas air dan pakan ikan yang baik dan benar, salah satu kendala adalah bahasa, sehingga perlu ceramah dan pelatihan yang menggunakan bahasa setempat. Untuk selanjutnya dapat direkomendasikan agar terus digalakkan dan dilakukan pembinaan yang melekat mengingat pengetahuan dan penerapan pengelolaan kualitas air ini masih merupakan hal yang baru dan merupakan peluang usaha yang prospektif di Desa Tombatu 3. Keywords: Kualitas Perairan, Komunitas, Manajemen.

Abstract

This study aimed to evaluate the effect of probiotic on growth and survival of tilapia (Oreochromis niloticus) against Streptococcus agalactiae infection. The test materials used were commercial probiotic bacteria and Streptococcus agalactiae. The probiotic bacteria were administered by mixing into the feed with a dose of 0 mL (without probiotics), 10 mL / kg of feed, 15 mL / kg of feed and 20 mL / kg of feed.  Feed was given 3 times a day at 08.00, 12.00 and 16.00 for 21 days. After that, the challenge test was done with Streptococcus  agalactiae bacteria by cohabitation. Bacteria with a density of 107 cells / mL were mixed into the water and allowed for 2 hours. The result showed that B treatment (10 mL / kg of feed) gave the best result with 93,33 percent of  survival rate. Statistical analysis showed that the survival of fish in treatments B, C and D was significantly different from treatment A (P <0.1). However, there was no significant difference between treatments B, C, and D. It was also found that the addition of probiotic in feed did not affect the growth of Nile tilapia (Orechromis niloticus). Keywords : Probiotic bacteria,  nile tilapia,  Streptococcus  agalactiae, growth,  infection

Abstract

The aim of this research was to study the effect of Binahong extract on the growth of Nile tilapia. A number of 225 fish measuring 10-12 cm in length with an average weight of 15 g was obtained from Fishery Development Center and Training, Tateli. The fish were put  in oxygenated plastic bags and transported to Laboratory of Aquaculture Technology. The fish was kept in aquarium equipped with an aerator with a density of 15 fish per aquaria. The test material used was the stem of Binahong plant stem, macerated with alcohol 70% for 3 days. The extract was then filtered with whatman filter paper and extract was concentrated using a Rotary Evaporator. The extract was further diluted to obtain  concentrations of 12.5, 25, 50, and 100 mg / mL Binahong  extract as treatment was given to the fish after mixed first into the pellet. The fish was fed with treatment feed for 30 days. Control feed was not supplemented with binahong extract. Growth data was measured at day 30 after treatment. The results showed that the extract of binahong had significant effect on fish growth (p <0.01) with the best result achieved at concentration of 100 mg/mL. In conclusion, supplementation of  binahong extract into fish feed could improve growth of  fish in which the best growth was obtained in fish fed diet containing 100 mg/mL of binahong extract.Keywords: Medicinal plants, tilapia, Anredera cordifolia, growth, maceration
