Abstract

The biofloc system is a solution for intensive cultivation activities. This is because in biofloc system the are heterotrophic bacteria that can reuse waste from cultured organisms so as to improve water quality. However, the biofloc system can cause high nitrite production if the dissolved oxygen concentration in the water is below the optimum value. High nitrite concentrations can cause brown nitrite, causing fish to suffocate even though the oxygen concentration in the water is sufficient. Polyculture can be a solution to reduce the concentration of biofloc so that brown nitrite can be prevented. Therefore, a research was conducted with the aim of knowing the effect of the composition of the best polyculture biota in order to produce high cultivation performance. The ratio of tilapia and catfish used included 80% catfish and 20% tilapia fish (treatment A), 70% catfish and 30% tilapia fish (treatment B), 60% catfish and 40% tilapia ( treatment C), and 100% catfish (treatment D). Maintenance is carried out for 60 days where feeding is done on a restricted basis. The results of the research carried out showed that the best FCR, ADG and SR were in treatment C with consecutive values of 1.27 ± 0.02 (FCR), 1.4 g/day (ADG) on the last maintenance day, 95.11 ± 1.02% (SR). This study shows that the performance of cultivation in biofloc systems in polyculture is better than monoculture.

Abstract

ABSTRACT In this study, a commercial product of natural silicates and yeast (NSY) and saponins from Yucca schidigera and Quillaja saponaria plants (SBP) were used to evaluate their nutritional effects on growth and health status of pacific white shrimp Litopenaeus vannamei. Four isonitrogenous and iso-lipidic experimental diets were formulated to contain 0%, 0.3% NSY, 0.2% SBP and 0.6% NSY. After 60 days, shrimp were sampled and standard haemato-immunological parameters were measured. The growth performances of shrimp were significantly affected by the dietary inclusion of NSY and SBP, whereas the inclusion of NSY and SBP provide a better growth compared to the control group. Additionally, the inclusion of NSY and SBP significantly enhance the total haemocytes count and lysozyme activity in shrimp compared to control. Therefore, NSY and SBP can be regarded as the functional ingredients in shrimp diet to improve the growth and non-specific immune function of shrimp.Keywords: Silicates and yeast, saponins, growth, health status, shrimp Litopenaeus vannamei ABSTRAK Pada kajian ini, produk komersial yang berbasiskan kepada komponen alamiah silikat dan ragi (NSY) dan saponins yang berasal dari tumbuhan Yucca schidigera dan Quillaja saponaria (SBP) digunakan untuk mengevaluasi pengaruhu nutrisi yang dimiliki terhadap pertumbuhan dan status kesehatan dari udang putih Litopenaeus vannamei. Empat pakan yang bersifat iso-nitrogen dan iso-lipid diformulasikan dengan perlakuan 0%, 0.3% NSY, 0.2% SBP and 0.6% NSY. Setelah 60 hari, udang kemudian diambil sampelnya dan protokol standard untuk uji hemato-immunologi dilakukan. Laju pertumbuhan udang secara signifikan dipengaruhi oleh keberadaan NSY dan SBP, dimana inklusi NSY dan SBP memberikan pertumbuhan yang lebih baik dibandingkan kontrol. Selain itu, penggunaan NSY dan SBP secara signifikan meningkatkan jumlah total hemosit dan aktivitas lisozim pada udang perlakuan dibandingkan kontrol. Oleh karena itu, NSY dan SBP dapat digolongkan sebagai bahan baku fungsional pada pakan udang untuk meningkatkan pertumbuhan dan fungsi imun non-spesifik pada udangKata kunci: Silikat dan ragi, saponins, laju pertumbuhan, status kesehatan, udang Litopenaeus vannamei

Abstract

A problem that often occurred for the actor of catfish cultivation was an indication of smelly mud/dirt/muddy taste (off-flavors). Off-flavors were identified from chemical geosmin compound (GSM) and 2-Methyl Iso-borneol (MIB) produced by Cyanophyceae (Blue Green Algae or BGA) and actinomycetes. This soil odor compounds was soluble in water, into the body of fish through the gill and forwarded to the fatty tissue of fish, so that the fish meat was finally mud-smelly/dirt/musty. Probiotics was an attempt to reduce the compounds that caused off-flavors. The use of probiotics containing Bacillus spp. on feed could degrade organic matter through bioremediation digestive organs and environmental fish farming to minimize the accumulation of organic matter. The reduced of organic matter in waters on total organic odor, has impacted on the percentage of BGA as cause of mud-smelly in waters, especially for species Oscillatoria Sp. In this study, the researchers used Bacillus spp. to treat 10 ml/kg and 20 ml/kg of feed that can indirectly lower the percentage of BGA, Oscillatoria population Sp. and off-flavor in catfish meat as compared to controls.

Abstract

Penggunaan probiotik merupakan salah satu alternatif yang dapat digunakan oleh pembudidaya ikan patin untuk meminimalisir permasalahan yang dialami pada setiap proses budidaya. Permasalahan tersebut erat kaitannya dengan mutu dan kualitas daging ikan, sehingga para pelaku usaha budidaya membutuhkan solusi terbaik untuk tetap menjaga mutu dan kualitas hasil produksi agar tetap dapat memenuhi kebutuhan ataupun permintaan pasar. Penelitian ini fokus pada upaya menurunkan bau tanah atau off-flavours melalui penggunaan probiotik Mina Pro (Bacillus spp.) yang didominasi oleh B. Licheniformis dan B. Subtilis. Pengaplikasian probiotik melalui pakan ikan dengan dosis 10 ml/Kg pakan dan 20 ml/Kg pakan. Hasil penelitian yang diperoleh kedua perlakuan lebih baik jika dibandingkan kontrol ditinjau dari beberapa parameter meliputi: Proksimat terutama pada kenaikan protein diperlakuan 10 ml/Kg pakan (17,1%); 20 ml/Kg pakan (16,7%); jika dibandingkan kontrol yang lebih rendah (14%). Komposisi bakteri organ lambung dan usus pada perlakuan 10 ml/Kg dan 20 ml/Kg pakan lebih banyak jika dibandingkan dengan kontrol. Hasil histopatologi organ perlakun 10 ml/Kg dan 20 ml/Kg pakan lebih baik. Karena banyak terbentuk villi yang mempermudah penyerapan nutrisi pakan. Organoleptik dari daging ikan patin (punngung, ekor dan perut yang diduga muddy) pada perlakuan 20 ml/Kg pakan lebih renah. 10 ml/Kg dan 20 ml/Kg pakan memiliki nilai lebih rendah (0,2 atau masih dalam kategori sedikit muddy/kurang muddy. jika dibandingkan dengan kontrol (0,3 atau dalam kategori muddy sedang).
