Abstract

Klungkung Regency, Bali has highly potential of marine fisheries, especially on capture fisheries. Capture fisheries potential was estimated 4.140,7 tons per year that consist of 2.898,2 tons of pelagic fishes and 1.242,5 tons of demersal fishes. Fishery products are a source of animal protein which is very beneficial for the body because they contain high protein and low fat. Furthermore, capture fisheries products are export commodities that can contribute for foreign exchange. Handling of fresh fishes is the most important part because it can affect the quality of fish product. Handling of fishery products is generally still on a traditional scale and is managed from generation to generation with limited capacity. “Pemindangan” processing in Kusamba Village, Dawan District, is one of the fish traditional handling techniques. Kusamba Village had very high production of Frigate Tuna, however not all Frigate Tuna can be processed with Pemindangan techniques. Thus, an alternative techniques for Frigate Tuna processing is necessary to improve the value of Frigate Tuna products. This products called “Sambal Tongkol”.The advantage of Sambal Tongkol are the manufacturing process does not require a long time and special expertise so that it can be adopted by local community in Kusamba Village. In addition, Sambal is one of favorite food products for Indonesian people as a staple food companion. Sambal products have been widely developed but not many have developed with the addition of Frigate Tuna. This community empowerment activity was expected to be able to improve soft skills of coastal communities which will be able to improve their economy as well.

Abstract

Provinsi Bali memiliki empat buah danau alam yang terletak di tiga kabupaten yaitu, Danau Beratan, di Kabupaten Tabanan, Danau Buyan dan Tamblingan di Kabupaten Buleleng dan Danau Batur di Kabupaten Bangli. Danau Beratan memiliki potensi sumberdaya perikanan dengan kekayaan jenis seperti : Ikan Mujair, Nila , Nilem, Karper, Nyalian, Lele, Gabus, Betok, Sepat, dan Ikan Zebra. Budidaya perikanan di sisi utara danau sudah dikembangkan dengan sistem keramba jaring apung (KJA). keberadaan ikan zebra yang dominan di suatu perairan menyebabkan pertumbuhannya menjadi lebih cepat daripada jenis ikan lainnya dan cenderung menjadi spesies pengganggu. Kondisi ini menyebabkan ketidakseimbangan sistem perikanan di Danau Beratan bahkan menimbulkan keresahan masyarakat nelayan yang menggantungkan hidupnya di perairan tersebut. Metode yang digunakan dalam melaksanakan kegiatan ini adalah metode penangkapan langsung (direct capture) bersama masyarakat nelayan dan pelaku lainnnya dengan mengunakan alat jaring kitcrik /pencar (hand net), alat jebak/bubu (trapper), serok atau ancho dan alat tangkap listrik (electrofishing). Metode yang lainnya adalah Focus Group Discussion (FGD) untuk memberikan pengetahuan dan pemahaman kepada Kelompok Nelayan Mina Puspa Merta, serta melakukan diskusi dan urun pendapat (umpan balik) tentang penanggulangan dan penangkapan ikan zebra yang merupakan masalah pokok di ekosistem perairan Danau Beratan. Populasi ikan zebra yang terus meningkat harus segera ditindaklanjuti dengan cara menangkapnya secara berkala, agar ikan-ikan asli atau ikan lokal yang bernilai ekonomis tinggi tidak hilang dari ekosistemnya.

Abstract

Ikan lele merupakan ikan air tawar yang telah lama dikenal dan dibudidayakan di Indonesia dan merupakan salah satu komoditas air tawar yang bernilai ekonomis penting. Permintaan pasar terhadap ikan lele cukup tinggi sehingga memiliki prospek untuk dibudidayakan secara intensif. Kegiatan budidaya ikan lele secara intensif menggunakan pakan buatan merupakan salah satu faktor penting dalam pertumbuhan ikan. Harga pakan buatan yang tinggi menyebabkan usaha budidaya sulit untuk berkembang. Untuk menyiasati mahalnya harga pakan, timbul kebutuhan terhadap bahan pakan yang lebih murah tetapi memiliki nilai nutrisi yang diperlukan ikan. Salah satu pakan alami yang memiliki kandungan protein tinggi adalah cacing tanah (Lumbricus rubellus). Pemberian pakan cacing tanah (L. rubellus) sebagai pakan alternatif selain pakan buatan dapat diterapkan untuk mengatasi permasalahan ketersediaan pakan tersebut. Dengan demikian diperlukan adanya pelatihan tentang cara budidaya cacing tanah (L. rubellus) sebagai pakan alternatif kepada pembudidaya ikan lele. Tujuan Pengabdian Kepada Masyarakat ini adalah untuk mengenalkan dan menerapkan teknologi budidaya cacing tanah (L. rubellus) sebagai pakan alternatif dalam budidaya lele dengan cara memberikan pelatihan (teori dan praktek) terhadap masyarakat pembudidaya. Kegiatan pengabdian kepada masyarakat ini dilaksanakan dalam tiga tahap, yaitu: survey lokasi, pendekatan masalah, pelatihan budidaya cacing L. rubellus, dan monitoring setelah pelatihan. Hasil kegiatan menunjukkan bahwa peserta memahami materi yang diberikan. Keberhasilan ditunjukkan dengan adanya respon positif dari peserta saat kegiatan pelatihan dan juga melakukan pengembangan terhadap kegiatan budidaya cacing L. rubellus sebagai pakan alternatif.

Abstract

Ikan nila merupakan salah satu komoditas budidaya unggulan khususnya untuk jenis ikan air tawar yang mengalami kenaikan rata-rata jumlah produksi terakhir yaitu 464 ribu ton pada tahun 2010 menjadi 482 ribu ton pada tahun 2011. Peningkatan produksi di dalam usaha budidaya dapat dicapai dengan cara mengoptimalkan kondisi lingkungan, penggunaan padat tebar yang sesuai dengan daya dukung lahan, kualitas benih yang baik dan pemberian pakan yang berkualitas sesuai dengan kebutuhan biota yang dibudidayakan. Pakan merupakan hal yang sangat penting diperhatikan dalam kegiatan budidaya ikan, baik secara semi intensif maupun intensif karena pakan merupakan komponen biaya produksi yang paling tinggi yaitu sekitar 35-70% dari biaya operasional. Hal inilah yang menyebabkan penggunaan pakan dalam budidaya perlu diefisienkan untuk dapat mengoptimalkan hasil produksi. Salah satu cara yang dapat digunakan untuk mengefisienkan penggunaan pakan dalam budidaya adalah dengan menggunakan aplikasi probiotik pada pakan buatan. Pemberian probiotik dalam pakan berpengaruh dalam saluran pencernaan, sehingga akan sangat membantu proses penyerapan makanan dalam pencernaan ikan. Bakteri probiotik menghasilkan enzim yang mampu menguraikan senyawa kompleks menjadi sederhana sehingga siap digunakan ikan. Metode yang digunakan dalam kegiatan ini adalah sosialisasi dan demonstrasi tentang aplikasi probiotik pada pakan buatan dalam budidaya ikan nila. Kegiatan ini akan dilakukan di Br. Delod Sema Cemagi, Ds. Serampingan, Kec. Selemadeg, Kab. Tabanan, Bali.

Abstract

Batur Lake is one of the lakes located in the Kintamani sub-district, Bali. This lake has abundant biodiversity, one of them is Red Devil fish (Amphilophus sp) which is a competitor of native and introduced fish. The research aims to find out the pattern of growth, size structure, and the physical and chemical conditions of waters. The method used was descriptive quantitative by using two trapping devices that were fishing rods and nets. Calculation results showed that a wide range of growth patterns of Red Devil (Amphilophus sp) fish on both trapping devices (fishing rods and nets) were grouped (Id<1). The highest sized structure value on the trapping devices (fishing rod) found in the water of Trunyan Village that was total length (TL) of 9,3 cm, Standard length (SL) of 7,3 cm, and weight: 16,5 gr. On the trapping devices (net) the highest value was found in the water of Songan Village that was total length (TL) of 13,5, SL of 11,1, and weight: 48,8 gr. The growth patterns of Red Devil (Amphilophus sp) fish based on length and weight analysis showed that were partly positive allometric and partly negative allometric. The result of the water quality measurement in the water of Batur Lake was about 26,3°C – 29,1°C (temperature), 5,36 mg/L – 6 mg/L, (DO), 7,2 – 7,8 (pH), and 87,1 cm – 147,8 cm (brightness).

Abstract

The living marine aquarium trade has been known to mediate various aquatic invaders to spread and established a new population outside of their natural home range. In most cases, the introduce species cause a cascaded effect which harm the native species and their ecosystem. The successful of the invasion event often related to the genetic properties of the introduced species. Therefore, using a molecular approach based on a mitochondrial DNA marker, the present work aimed to evaluate the population genetic structure of the introduced P. kauderni population in Bali Strait. Samples were collected from four sites in Gilimanuk Bay, Bali Strait. Our results showed  a high haplotype diversity and low nucleotide diversity that might be a signal of a bottleneck. Overall, we found five haplotypes comprising two unique haplotypes and three shared haplotypes. Genetic structure was detected in some localities, which indicates Pterapogon kauderni might originated from various genetically distinct populations. However, we could not conclusively determine the observed patterns of the genetic structure within each site. These patterns are likely related to the multiple introduction event of P. kauderni in Bali Strait. Additional samples from both side (introduced and native habitat) combined with more rapidly evolving markers may describe the structure more clearly.

Abstract

Eel (Anguilla sp.) is an export commodity that has high economic value, but in the development of cultivation encountered a problem on the treatment period. To reach consumption size it takes 12-16 months. To improve productivity and provide added value needs polyculture systems with tilapia which is easy in terms of its treatment and can stabilize water quality. The aim of this study was to determine the productivity of eels using polyculture systems with tilapia. The research was conducted at BLUPPB Karawang in February – April 2015, using six (6) pool of treatment. Three pools were used for activities with a polyculture system and three pools were used for the treatment of non-polyculture. The results showed that a polyculture system of eel and tilapia treated for 60 days can make a positive impact to the Specific Grow Rate (SGR) 0.98%, and Food Conversion Ratio (FCR) 1.09 when compared with non-polyculture with SGR (0,93) and FCR (1.23). The results of analysis of effort on polyculture systems can provide the added value of the tilapia harvest.

Abstract

This study aims to determine the prevalence and intensity of parasitic infections in layur fish (T. lepturus) sold in Kedonganan Fish Market. Layur fish (T. lepturus) were studied as many as 40 birds and identified in the Fisheries Science Laboratory, Faculty of Marine and Fisheries, Udayana University. Parasites observed were ectoparasites and endoparasites. The results of the research data were analyzed by calculating the difference in prevalence, intensity of infection, and correlation test to determine the relationship between length and intensity, weight with intensity, and descriptive calculation to determine the level of infection in various organs. The results showed that the prevalence of parasitic infections in layur fish (T. lepturus) marketed in the Kedonganan Fish Market was included in the ‘always’ category with a value of 95%. According to William and Bunkley (1996), this ‘always’ category illustrates that ordinary parasites infect fish by 90-98%. The intensity of parasitic infections was 815 parasitic individuals with an average intensity of 21.44 parasites / fish. After a correlation test, the relationship between the length and weight of the fish with the intensity of parasitic infection was positively correlated but with a weak relationship with values ??of 0.029 and 0.146, where each fish increased in length and weight, it did not necessarily increase the intensity of parasitic infections.

Abstract

The Indian scad (Decapterus russeli) is a pelagic fish that has high economic value, found throughout the Indonesian waters. The availability of Indian scad resources makes this fish easy to find, especially in Kedonganan Beach, Bali. The use of Indian scad for human consumption makes it necessary to pay attention to the quality of indian scad in order to avoid fish diseases, such as parasites. The attack of endoparasites in Indian scad can be zoonotic, which can be dangerous for humans who consume them, so research is needed to determine the density of endoparasite attacks and the percentage of endoparasites in indian scad. Samples of Indian scad (D. russeli) were obtained randomly from PPI Kedonganan and Kedonganan Fish Market. The observed organs were intestines, gonads and liver. The research was conducted for 1 month from 16 December 2020 to 17 January 2021 and fish samples were taken by random sampling. There were 35 fish samples (D. russeli) examined. The endoparasites found were Anisakis sp. (316 individuals), Camallanus sp. (15 individuals), and Lecithocirium sp. (33 individuals). The highest intensity in the genus Anisakis was 9.2 ind/fish and was classified as moderate infection and the highest prevalence was also in the Anisakis genus, which was 97.14% with (almost always categories), 60% of the genus Lecithocirium (very frequent categories), and the Camallanus genus of 28.50% with (frequent category).
