Abstract

The aim of this experiment is to evaluate the nutrient quality of leucaena leaf meal (LLM) with addition of sheep rumen fluid enzyme for nile tilapia feed and incubated in vitro either for 2 or 24 hours. This experiment was arranged in a completely randomized design with 6 treatments and 3 replications. Those treatments were enzyme levels of 0, 20, 40, 60, 80, and 100 ml/ kg LLM. Results showed that nutrient quality of LLM with addition of sheep rumen fluid enzyme that incubated for 24 hours had the best result compared to that incubated for 2 hours. This finding significantly affected (PO.05) on the increase of sugar release (76.97%), soluble glucose (21.27%) and soluble protein (37.7%). It is concluded that sheep rumen fluid enzyme has a great potential for improving nutritional quality of leucaena leaf meal of fish feed.

Abstract

This study was conducted to find out the health status of humpback grouper fish(('hrtmtileptes altiverts) that are fed on inorganic-iron supplement. Both, thetreatment and the control was tested in anoxia condition. The fish (average weight4.18±0.13 g/ind) was cultured in 60x40x50 cm3 aquarium and stocked by 10indJaquarium. The fish was reared for 10 weeks: and they were fed threetimes/day at satiation. Results shown that the fish fed by non-iron supplement wasmore susceptible than the normal condition; base on the index of leucocytes,nionocytes. phagocytic and MCHC distribution. However, 25 mg Fe/kgsupplement in the diet was increased concentration of Fe by 35% - 100% in liver,intestine, body tissue and enhance fish vitality at anoxia condition. The survivalrate of fish increased by 1.3 times compare to the non-iron supplementation.

Abstract

This experiment was conducted to investigate blood glucose performance of giant gouramy (Osphronemus gouramy, Lac.) to environmental changes. Fish with body weight of about 52,15 g was used in the experiment. A hundred and twenty fish were subjected to stress by moving them to another aquarium containing cooler water for 5 minute before put them back to the origin aquarium. The stress treatments were Δ 0°C (A), Δ-3°C (B), Δ-6°C(C), and Δ-9°C(D). Blood glucose was measured at 0, 1, 2, 3, 4 and 5 hours post stress, each for 5 fish. During stress treatment, the survival offish were recorded. To study the role of insulin activation on reducing the stress effects, thirty fish were injected with insulin 2 IU/100 g body weight before subjected them to stressar. Blood glucose level of fish subjected to temperature stress of Δ-9°C was the greatest. The blood glucose response to temperature changes was linear, Y = 4,4543 X + 35,553 with R2 = 0,09976. The survival rate of fish was 100% for all treatments. Injected of insulin 2 IU/100 g body weight was able to reduce hyperglycemia that caused by stress.

Abstract

A triplicate experiment was conducted to evaluate the addition of probiotic Bacillus sp. into the diet on feed convertion and growth of catfish Pangasius hypophthalmus. Twenty fish with an initial body weight of 1,85 ± 0,09 g were stocked in a 60-1 aquarium. During rearing period, fish were fed on the diet three times a day at satiation. Prior the feeding, probiotic (contained Bacillus sp. 4,2x106 CFU.ml-1) were added into the diet at a dosage of 0, 5, 15 or 25 ml.kg-1 diet. The probiotic were added once a day at the noon. The results showed that maximum protein retention, lipid retention, growth rate, and minimum feed convertion was found in the group of fish fed on the diet supplemented with 15 ml probiotic kg-1 diet. Irrespective to the dosage of probiotic, food consumption and survival rate of fish were the same among the treatments. Key words : Probiotic.

Dua puluh ekor ikan patin dengan bobot rata-rata 1.85 ± 0,09 g ditebar dalam setiap akuarium frekuensi 50x40x35 cm yang diisi air 60 1. Selama 40 had masa pemeliharaan. ikan diberi pakan buatan berkadar protein 27% dengan frekwensi tiga kali sehari, at satiation. Sebelum diberikan ke ikan, pakan tersebut ditambah produk probiotik (mengandung Bacillus sp. 4,2 x 106 CFU/ml) dengan dosis 0, 5, 15 atau 25 ml/kg pakan. Pakan yang mengandung probiotik hanya diberikan sekali setiap hari, yakni pada pukul 13.00. Hasil penelitian menunjukkan bahwa adanya penambahan probiotik dalam pakan sampai dosis 15 ml/kg pakan menyebabkan terjadinya peningkatan retensi protein, retensi lemak dan laju pertumbuhan harian ikan, serta menurunkan konversi pakan. Penambahan probiotik lebih lanjut (25 ml/kg pakan) menurunkan kinerja pertumbuhan di atas. Sementara itu. kelompok ikan di setiap perlakuan mengkonsumsi pakan dalam jumlah yang tidak berbeda nyata, yaitu antara 132,43 g sampai 137,84 g. Hasil penelitian juga menunjukkan bahwa penambahan probiotik di dalam pakan tidak memberikan adanya perbedaan yang nyata terhadap tingkat kelangsungan hidup ikan, yaitu antara 98,3% - 100%.

Abstract

ABSTRACTThe objective of the present experiment was to study the most optimum taurine enrichment concentration of rotifers in improving Pacific white shrimp larva Litopenaeus vannamei survival and development. White shrimp larvae at sixth naupliar stage were reared in 12 units of 500 L fibre glass tanks with a stocking density of 125 ind/L. Starting from zoea two stage (Z-2), the larva was provided with rotifers with different taurine enrichment concentration according to the treatments, i.e. 0 mg/L enrichment medium (A), 25 mg/L (B), 50 mg/L(C), and 100 mg/L (D). The results show that different taurine concentration in the enrichment media increased taurine level in rotifers. Furthermore, the administration of taurine enriched rotifers up to 50 mg/L significantly improved larval survival and may accelerate larval development. The experimental results also concluded that a concentration of 50 mg/L is the most optimum taurine enrichment concentration of rotifers for the improvement of white shrimp larval survival and developmental stage.Keywords: taurine, rotifer, white shrimp, enrichmentABSTRAKPenelitian ini bertujuan untuk mengkaji konsentrasi optimum taurin melalui pengayaan pada rotifera terhadap tingkat kelangsungan hidup dan perkembangan stadia larva udang vaname Litopenaeus vannamei. Larva udang vaname stadia naupli-6 dipelihara dalam 12 tangki fiberglass volume 500 L dengan kepadatan 125 ind/L. Dimulai sejak stadia zoea 2 (Z-2) larva diberi rotifera yang diperkaya dengan taurin dengan konsentrasi yang berbeda sesuai dengan perlakuan, yaitu 0 mg/L media pengkaya (A), 25 mg/L (B), 50mg/L (C), dan 100mg/L (D). Hasil penelitian menunjukkan pengayaan taurin pada konsentrasi yang berbeda menyebabkan peningkatan kandungan taurin rotifera. Sementara pemberian rotifera yang diperkaya taurin hingga 50 mg/L meningkatkan kelangsungan hidup dan mempercepat perkembangan stadia larva udang. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa pemberian rotifera yang diperkaya taurin dengan konsentrasi 50 mg/L menghasilkan tingkat kelangsungan hidup tertinggi (53,5%) dan perkembangan larva yang tercepat (p<0,05) dibandingkan perlakuan lainnya.Kata kunci: taurin, rotifera, udang vanname, pengayaan
