Balongan Village is one of coastal area in Indramayu which is potential for aquaculture development. Community development through catfish culture activity in this village had been done for 3 years from December 2011-December 2014. This activity aimed to improve the community skill especially catfish culture using plactic pond. Methods used in this activity was training and empowering. The community was trained about plastic pond construction and fish culture technique. The community participated in first year was 21 people, second year was 26 people, and third year was 13 people. Supporting scheme in this program was one pond sized 5 x 5 m<sup>2 </sup>for one person, including fish larvae (seed) and feed for twice harvesting. There were two principal approaches had been done to empower the catfish culture activity which were technical and participative approach. The success of catfish culture program could be seen from three aspects namely participation, community income, and social modal utilization. Based on the training and empowering results, community had ability to culture and harvest the catfish reared in the plastic pond.
Penggunaan shelter pada pendederan lobster Panulirus homarus dimaksudkan untuk menekan terjadinya stress dan menghasilkan tingkat kelangsungan hidup yang lebih tinggi. Penelitian ini bertujuan untuk menganalisis dan menentukan jenis shelter yang memberikan respon stress dan produktifitas benih lobster yang paling baik. Pada Penelitian ini digunakan empat perlakuan, perlakuan menggunakan shelter jaring, paralon, lubang angin dan kontrol (tanpa shelter). Penelitian menunjukkan, perlakuan menggunakan shelter paralon merupakan yang terbaik karena terbukti mampu untuk menurunkan tingkat stress dan menghasilkan kelangsungan hidup yang lebih baik. Level Total Hemocycte Count (THC) dan glukosa pada sheltter paralon selama penelitian, menghasilkan respon stress yang lebih rendah dan stabil apabila dibanding dengan perlakuan lainnya.Tingkat kelangsungan hidup pada shelter paralon berbeda nyata (p<0,05) dengan shelter jaring dan kontrol, tetapi tidak berbeda nyata (p>0,05) dengan shelter lubang angin.
<p>Larva rearing is one of the efforts to increase white shrimp <em>Litopenaeus vannamei</em> seed quality. This study was conducted to determine effect of rearing density on the quality and productivity of white shrimp larvae in cage system. The tested rearing densities were 500, 1000, 1500 and 2000 ind/m<sup>2 </sup>and cultured for 28 days. The result showed that rearing density did not affect survival rate and coefficient of variation of shrimp length. The treatmentonly affected the shrimp larvae growthwhere 500 ind/m<sup>2</sup> rearing density gave the best growth.</p> <p>Keywords: white shrimp, larva, rearing density, net cage</p> <p> </p> <p>ABSTRAK</p> <p>Penokolan merupakan salah satu usaha untuk meningkatkan kualitas benih udang vaname (<em>Litopenaeus vannamei</em>). Penelitian ini dilakukan untuk mengetahui pengaruh padat tebar terhadap kualitas dan produktivitas pemeliharaan larva udang vaname di hapa. Padat tebar yang diuji meliputi 500<sup> </sup> ,1000, 1500 <sup> </sup> dan 2000 ekor/m<sup>2 </sup>selama 28 hari pemeliharaan. Hasil penelitian menunjukkan bahwa padat tebar tidak mempengaruhi kelangsungan hidup dan koefisien keragaman panjang udang, dan hanya mempengaruhi pertumbuhan. Kepadatan 500 ekor/m<sup>2 </sup>menghasilkan pertumbuhan terbaik.</p> <p>Kata kunci: vaname, larva, kepadatan, hapa</p>
The water level in the cultivation of eel (Anguilla bicolor bicolor) is an important study in order to provide the optimal water level for cultivation. Optimizing the water level will affect the substitution of respiration energy with energy to grow. In addition, the water level information is related to the efficiency of water use for eel production in the future. Information on water level for eel production is still very limited, so this research is necessary to do. A total of 120 eel elver (initial weight 13.66 ± 0.09 g) were collected from eel companies in Bogor City, Indonesia. Fish were reared in vertical aquaculture systems with a stocking density of 10 fish per container for 60 days. The artificial feed containing 55% protein given as much as 3–5% of the biomass. Absorption and water replacement were done 20% per day. The result of this research showed that fish weight increased with an average of 33.45 ± 0.33 g. Different water levels had an impact to KKb, SGOT, ALP, and He. There was erosion of the skin epidermis and necrosis of the gill filaments due to the adaptation process. Water quality was within the optimum range for all treatments and 1.5 cm water level is recommended for maintenance (SGOT, ALP and He values were closest to normal values).
ABSTRAKDesa Karangsong merupakan salah satu desa di wilayah pesisir Indramayu yang memiliki potensi sumber daya perikanan dan kelautan cukup besar, (baik perikanan tangkap dan budi daya). Jenis perikanan budi daya yang banyak berkembang di desa ini adalah budi daya udang dan bandeng. Kegiatan pemberdayaan masyarakat melalui pengembangan polikultur bandeng dan udang di desa ini berlangsung selama 2 tahun 4 bulan dari bulan Desember 2012 sampai April 2015. Kegiatan ini bertujuan untuk meningkatkan keterampilan masyarakat terutama dalam pemeliharaan bandeng dan udang dengan sistem polikultur. Metode yang dilakukan, yaitu melalui pelatihan (teori dan praktik) dan pendampingan dengan materi berupa pengetahuan tentang persiapan tambak dan teknis pemeliharaan bandeng dan udang. Masyarakat yang terlibat dalam kegiatan polikultur bandeng dan udang pada tahun pertama sebanyak 4 orang dan tahun kedua bertambah menjadi 9 orang. Skema pemberian bantuan yaitu satu paket (benur udang, benih ikan bandeng, dan pakan) yang diberikan pada tiap sasaran. Melalui pendampingan yang efektif masyarakat merasakan adanya penambahan pengetahuan, teknologi, panen, dan pendapatan (912 juta dari panen bandeng; 920 juta dari panen udang).Kata kunci: desa karangsong, Indramayu, pemberdayaan masyarakat, polikultur ABSTRACTKarangsong Village is one of the coastal villages in Indramayu which has a high fishery and marine resources potential, (both capture and aquaculture fisheries). The aquaculture activities in this village were mostly milkfish and prawn cultures. Community development through polyculture activity in this village had been done for 2 years 4 months from December 2012 to April 2015. This activity aimed to improve the community skill, especially milk fish and prawn using polyculture system. Methode used in this activity was training and empowering. The community was trained about pond culture preparation and milk fish and prawn culture methods. The community participated in first year was 4 people, and second year was 9 people. Aid distribution scheme of this program was 1 package for each fish-farmer contained prawn seed, milkfish seed, and fish-prawn feed. Through effectively empowering program, people knowledge, technology, biomass farming, and income (912 million from milkfish farming; 920 million from shrimp farming) were increased.Keywords: community empowerment, Indramayu, Karangsong village, polyculture, PENDAHULUANIndramayu merupakan salah satu kabupaten di Provinsi Jawa Barat yang memiliki potensi sumber daya kelautan dan perikanan yang cukup besar.
