Abstract

The development of sustainable and economically sound practical diet in the coming years will depend on the reduction of fish meal and the increased inclusion of sustainable protein sources. Over the years, our laboratory has systematically reduced the inclusion levels of fish meal and other animal protein sources by using a range of alternative plant-protein sources. These diets may be further improved through the use of specialized proteins, supplements for limiting amino acids, enzyme and attractants. Good success has been seen with corn protein concentrates, advanced processing products of soybean meal, such as soy protein concentrates and advanced soy product (enzyme treated or fermented soy). Based on the results of our research, the proportion of animal meal can be reduced to 12 % in our current formulations without any detrimental effects on pompano performance and nutrient retention. In addition, the use of fermented soy or the combination of enzyme-treated soy with proper inclusion level of squid hydrolysates as an attractant has proven to improve the functional properties of SBM and lead to better liver and intestine condition of pompano. Considering the sizeable body of knowledge concerning nutrition for Florida pompano, all information taken from this species could be used as the starting point to develop better feed formulations for Silver pompano production in Indonesia.

Abstract

ABSTRACT This experiment was aimed to investigate the effects of protein hydrolysates on growth performance and immune response of the Asian sea bass Lates calcarifer Bloch. The experiment was performed in two different rearing period, namely nursery and grow out by using completely randomized design. Experimental fish were fed with three types of diets and each treatment was repeated three times: a local commercial diet (control), coated or not, with 2%, and 3% of protein hydrolysates. Challenge test was performed with Vibrio parahaemolyticus at a density of 105 sel/mL by using immersion method. The results showed that the the neutrofil, leukocyte and monocyte of the fish fed on protein hydrolisates were significantly higher than those non-supplemented group (P<0.05). Meanwhile, the lymphocyte on the fish treated with hydrolisates showed no difference amongst treatments (P<0.05). The growth performance of Asian sea bass fed on protein hydrolisates significantly improved the total fish weight (g), relative weight gain, specific growth rate, final weight (g) and final length (cm) in comparison to the control (P<0.05) both at nursery and grow out phase. Higher survival both at the nursery and grow out phase were obtained by the group fed with 3% protein hydrolisates: 97.28±0.18% and 86.0±4.32%. Followed with 2% supplementation level 96.75±0.28% and 78.4±7.7%. The lowest survival was shown by the control group with 93.65±0.13% and 20.1±21.1% from nursery and grow-out phase respectively. Results of challenged test showed that the protein hydrolisates supplementation was able to improve the post-challenged survival and resistency of Asian sea bass against V. parahaemolyticus infection. Fish treated with 3% protein hydrolisates generated higher survival 78,33±2,89%, followed by treatment 2% 73,33±5,77%, and control 31,67±7,64% after five days post immersion (P<0.05). Keywords: Asian sea bass, protein hydrolisates, growth, immune system   ABSTRAK Penelitian ini bertujuan untuk menguji efektivitas suplementasi protein hidrolisis pada pakan terhadap respons kekebalan tubuh dan performa pertumbuhan ikan kakap putih Lates calcarifer. Penelitian dilakukan di dua fase pemeliharaan, yakni fase pendederan dan pembesaran dengan menggunakan rancangan acak lengkap. Penelitian ini menggunakan tiga perlakuan dan masing–masing perlakuan memiliki tiga ulangan, dengan deskripsi perlakuan adalah kontrol, aplikasi 3% dan 2% protein hidrolisis. Uji tantang dilakukan dengan menggunakan Vibrio parahaemolyticus pada konsentrasi 105 sel/mL dengan metode perendaman. Hasil analisa respons kekebalan tubuh menunjukkan bahwa neutrofil, leukosit, dan monosit pada kelompok ikan yang mendapatkan aplikasi protein hidrolisis meningkat secara nyata dibandingkan kontrol (P<0,05). Sementara limfosit pada kelompok perlakuan protein hidrolisis tidak memiliki perbedaan yang nyata dibandingkan kontrol (P<0,05). Performa pertumbuhan ikan kakap putih yang mendapatkan suplementasi protein hidrolisis juga memiliki total bobot (g), % bobot relatif, % laju pertumbuhan spesifik, bobot akhir (g) dan panjang akhir (cm) yang secara nyata lebih baik jika dibandingkan dengan kontrol (P<0,05) baik pada masa pemeliharaan di pendederan maupun di pembesaran. Sintasan paling tinggi pada fase pendederan dan pembesaran terdapat pada kelompok suplementasi 3% dengan 97,28±0,18% dan 86,0±4,3%. Diikuti oleh kelompok 2% dengan 96,75±0,28% dan 78,4±7,7%; dan paling rendah diperoleh pada kelompok kontrol dengan 93,65±0,13 % dan 20,1±21,1% masing-masing dari fase pembenihan dan pembesaran. Hasil uji tantang menunjukkan bahwa suplementasi protein hidrolisis mampu meningkatkan sintasan dan meningkatkan resistensi ikan uji terhadap infeksi V. parahaemolyticus. Pemberian protein hidrolisis dengan konsentrasi 3% merupakan dosis terbaik dengan sintasan 78,33±2,89%, diikuti oleh aplikasi 2% dengan 73,33±5,77% dan kontrol dengan 31,67±7,64% setelah lima hari masa uji tantang (P<0,05). Kata kunci: ikan kakap putih, protein hidrolisis, pertumbuhan, sistem kekebalan tubuh

Abstract

ABSTRACT The aim of this study was to evaluate the use of unique mixture of nano-nutrient to extent the growth of diatom Thalassiosira sp. and the effect to the water quality, growth performance, and protein composition on the whole body of the Pacific white shrimp Litopenaeus vannamei. There are four treatments with four replicates per treatment with the use of commercial nano-nutrients (Aquaritin Aquaculture or AA) namely: (1) 0.70 mg/L; (2) 0.525 mg/L, (3) 0.35 mg/L, and (4) without any AA application, but included standard application of using urea and NPK fertilizers to enhance the growth of diatom. The use of AA was successful to trigger the growth of Thalassiosira sp. Group of shrimp treated with 0.70 mg/L had better growth rate. Results of feeding trial indicated that adding AA could also improve the biomass, final mean weight, survival, percentage weight gain, and better feed utilization in terms of FCR. The addition of AA to enhance the growth of Thalassiosira sp. also provides a beneficial impact to the protein composition in whole body of shrimp. Biologically, the protein composition in the whole body of shrimp treated with 0.7 mg/L was higher. The findings from this study showed that the addition of commercial nano-nutrient could enhance the growth of Thalassiosira sp. and led to better growth of shrimp cultured in concrete tank Key words: Growth, Litopenaeus vannamei, nano-nutrients, protein composition, Thalassiosira sp. ABSTRAK Tujuan penelitian yaitu mengevalusi penggunaan campuran unik nano-nutrien untuk meningkatkan pertumbuhan diatom Thalassiosira sp. dan pengaruhnya terhadap kualitas air, laju pertumbuhan, dan komposisi protein pada tubuh udang L. vannamei. Terdapat empat perlakuan dan empat ulangan per perlakuan dengan penggunaan nano-nutrisi komersial (Aquaritin Aquaculture atau AA) yaitu: (1) 0,70 mg/L; (2) 0,525 mg/L; (3) 0,35 mg/L, dan (4) tanpa pemberian AA, tetapi menggunakan penerapan standar pupuk urea dan NPK untuk pertumbuhan diatom. Penggunaan AA berhasil memicu pertumbuhan Thalassiosira sp. Kelompok udang yang diberi perlakuan 0,70 mg/L memiliki laju pertumbuhan yang lebih baik.

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
