Abstract

High fish stock density causes a decrease in water quality due to increased organic waste in water media and this can be overcame using biofloc technology. The bacterial consortium in the biofloc system breaks the organic compound into nutrients for phytoplankton growth. This research aims to determine phytoplankton abundance in biofloc ponds with different catfish stocking densities. Furthermore, a completely randomized design (CRD) was used, with four treatments and three replications. The treatments involved 1,000, 1,500, 2,000, and 2,500 catfish per m3, respectively, with a weight of ± 1-3 grams. Also, the fish was fed 3% of its body weight and reared for 40 days in a tarpaulin pond, with a water volume of ± 1,974 L. The AMOVA test was used to analyze the data and 10 phytoplankton genera were observed. However, the phytoplankton abundances showed no statistical significance among the treatments. The results showed that the first treatment had the most abundant phytoplankton, with an average number of 13,394 cell/L.Keywords:AbundanceBioflocCatfishDensityPhytoplankton

Abstract

Bonylip barb fish is an aquaculture commodity that has the potential to be developed in Banyumas district. In its cultivation activities, bonylip barb are able to consume artificial feed well. The feed consumed will affect the digestive condition. The fish digestive tract is a complex system whose main functions are digestion and absorption. Nutrient absorption in intestinal cells is influenced by active transport of Na+ (sodium) ions. Na+ and Cl ion levels are obtained through water and feed. This study aims to determine the effect of salt supplementation in commercial feed with different concentrations on bacterial abundance. The research was carried out experimentally with salt supplementation doses (0%, 1%, 2%, 3%, and 4%; w/w) to be applied to bonylip barb seeds (5-7 cm) for 60 days. Research parameters include bacterial abundance, positive and negative gram tests. The results showed that the treatment with the addition of 2% NaCl gave a total number of bacteria that tended to be higher than the control (0% NaCl). The total number of bacteria in the digestive tract of Nilem fish that were given NaCl addition to the feed ranged from 3.78 ± 6.27 x 106 CFU/gram to 32.04 ± 19.51 x 106 CFU/gram. The addition of NaCl affects the proportion of gram positive and negative in the digestive tract of tilapia (Oreochromis niloticus). Gram positive bacteria tended to dominate in the 2% NaCl treatment at 69.99% and gram negative bacteria at 21.69%.

Abstract

Perkembangan budidaya ikan nila yang meluas hingga ke perairan payau dan laut membuat riset terkait proses aklimatisasi ikan nila pada kadar salinitas yang berbeda perlu dilakukan untuk mengetaui sejauh mana ikan nila dapat bertahan. Tujuan dari penelitian ini adalah untuk mengetahui jumlah bukaan operkulum dan kadar glukosa darah ikan nila yang dipelihara pada kadar salinitas yang berbeda. Jumlah ikan nila yang digunakan dalam penelitian ini adalah 15 ekor dengan dua salinitas yang berbeda yaitu 0 ppt dan 10 ppt. Rataan jumlah bukaan operculum ikan nila pada salinitas 0 ppt adalah sebesar 437,45 / 5 menit sedangkan pada salinitas 10 ppt sebesar 422,47 / 5 menit. Penurunan jumlah bukaan operkulum selaras dengan penurunan kadar glukosa darah. Pada salinitas 0 ppt kadar glukosa darah sebesar 241 mg/dl sedangkan pada salinitas 10 ppt sebesar 203,67 mg/dl. Kadar salinitas 10 ppt masih dapat ditoleransi oleh ikan nila.

Abstract

Suplementasi garam dalam pakan ikan mempunyai peluang meningkatkan efisiensi produksi perikanan budidaya melalui peningkatan pertumbuhan ikan. Tujuan penelitian ini adalah mengkaji performa pertumbuhan Nilem (Osteochilus vittatus) yang diberi pakan dengan suplemen garam. Penelitian eksperimen dilaksanakan menggunakan rancangan acak lengkap, terdiri atas lima perlakuan dan enam ulangan. Perlakuan berupa suplementasi garam dengan dosis 0% (kontrol), 1%, 2%, 3%, dan 4%. Benih ikan (2,3 ± 0,16 g) dipelihara dalam sistem resirkulasi menggunakan wadah berisi 40 liter air dengan kepadatan 15 ekor per wadah dan diberi pakan uji selama 30 hari. Pertumbuhan ikan dan kualitas air diamati secara periodik. Hasil penelitian menunjukkan kelompok ikan yang diberi suplementasi 3% garam memiliki pertumbuhan yang tidak signifikan lebih baik berdasarkan pertambahan berat, relative growth rate (RGR) dan specific growth rate (SGR). Ikan perlakuan 2% garam menunjukkan faktor kondisi yang cenderung lebih tinggi dibandingkan ikan perlakuan lain, namun tidak signifikan secara statistik. Suplementasi garam tidak meningkatkan pertumbuhan ikan secara nyata namun berpotensi dapat membuat produksi budidaya Nilem menjadi lebih efisien.

Abstract

Mangrove forests have an important role in reducing the impact of global warming as a place to absorb carbon dioxide (CO2) from the atmosphere which is mostly stored in sediment. Mangroves are a good habitat for aquatic biota such as macrozoobenthos. Macrozoobenthos are organisms that inhabit the bottom of sea waters and also exist in stable sediments. The aim of this research is to determine sediment texture, sediment organic carbon content, macrozoobenthos abundance and the relationship between sediment type and macrozoobenthos abundance. The method used in sampling was purposive sampling with a total of 3 stations. Sediment samples were taken using a core sampler at depths of 0-10 cm, 10-20 cm and 20-30 cm, while macrozoobenthos samples were taken using the hand sorting method. Organic carbon content was analyzed using the Loss on Ignition (LOI) method. The research results showed that the macrozoobenthos community structure at all stations produced low diversity and dominance indices and high uniformity indices.   The type of sediment texture in the research area shows an average value of the sediment fraction of 4.43% sand, 71.11% dust and 24.45% clay. The highest organic carbon content was found at stations near brackish water areas with an average of 12.06%, while stations near factory areas had the lowest content at 5.89%. There is a strong relationship between the type of sediment texture and the abundance of macrozoobenthos in the Karangtalun mangrove area, North Cilacap.

Abstract

Mangrove forests function as a place for the survival of various marine biota such as fish, shrimp, and crabs, especially the mangrove forest area in Tritih Kulon and Karangtalun Villages, Cilacap Regency. Mangrove forests in the area also function as a place for the reproduction of living things that can support the economy of the local community. The purpose of this internship is to determine the economic potential of the mangrove ecosystem and to determine the economic impact of the existence of the mangrove ecosystem on the income of local communities in Tritih Kulon and Karangtalun Villages, Cilacap Regency. This internship was carried out by conducting interviews and distributing questionnaires to obtain data. The results of the internship showed that the economic potential of mangrove forests in the Tritih Kulon area is quite high, namely IDR 330,430,000 and IDR 53,700,000 in Karangtalun Village. The existence of mangrove forests in both locations brings economic value to the local community through tourism activities, fisheries, and home industry production. It is hoped that this research can be a reference in the development of mangrove ecosystems in the future.
