The purpose of this research was to determine the effect of yeast (Saccharomyces cerevisiae) with different composition of 5%, 10%, 15%, 20%, and without yeast in feed formulation on growth of tilapia (Oreochromis niloticus). The experimental fish used in this study had an average lengths of 2-3 cm  and weight of 1.0 g.  This research used cage measuring 100 x 100 x 100 cm3 that was placed in outdoor concrete pond of 3.5 x 5 m2.  Each cage filled with 10 fishes with three replication.  The dose given to the fish was 10% of the weight of biomass.  The fish was fed for three weeks, 3 times a day at 08.00 am, 12.00 pm, and 16.00 pm.. Research results showed that the greatest growth was achieved in fish treated 20% yeast and the lowest was observed in control fish (without yeast). Based on statistical analysis, all treatment displayed similar effect on all growth parameters.Keywords: Fish feed, Saccharomyces cerevisiae, yeast, Nile tilapia, fish growth

Test Fish

In this study, fish feed supplemented by probiotic, prebiotic and synbiotic were applied to enhance the immune response and survival rate of the fish against Streptococcus agalactiae infection. Treatments used in this study, were as follows: feed containing 1% (v/v) of probiotic (C), feed containing 2% (v/v) of prebiotic (D) and feed containing mixed of 1% (v/v) of probiotic + 2% (v/v) of prebiotic (E, defined as synbiotic). Control fish (both positive, A; and negative, B; treatments) were fed by fish feed without containing neither probiotic nor prebiotic. In this study, test fish used monosex (all male) red tilapia with the average of body weight of 13,43±2,97 gram. The fish were fed by supplemented feed within first 30 days pre injection. After that, the treated fish were challenged by 109 CFU/ml of S. agalactiae. Nile tilapia fed by synbiotic (treatment E) had higher immune response (haemoglobin, neutrofil, and phagocyte indices) than control, but were not significantly different than those of treatment C, and D. After challenged test by S. agalactiae, treatment C, D and E resulted significantly higher resistance than that of control. The survival rate of fish fed by supplemented feed containing probiotic (C), prebiotic (D) and synbiotic (E) were 76%, 76% and 80%, respectively; higher than than positive control (50%). The results showed that addition of probiotic, prebiotic and synbiotic in fish feed could increase immune response and survival rate against S. agalactiae.Keywords : tilapia, probiotic, prebiotic, synbiotic, Streptococcus agalactiae

This study aims to examine the effect of sponge crude extract addition to the fish feed on growth and non-specific immune response of nile tilapia (O. niloticus) and determine the most effective dose of the extract in raising the growth and the non-specific immune response of nile tilapia (O. niloticus). The sponge sample was macerated and then evaporated using a rotary vacuum evaporator until the sample became a paste and mixed with feed. The fish were fed for 14 days respectively as much as 5% of body weight per day with feeding frequency of two times a day. The results showed that addition of sponge crude extract to the fish feed gave good effect on the growth and the non-specific immune response of nile tilapia (O. niloticus) with best dose of  40 g / kg feed.Keywords: Sponge extract, fish immune response, fish growth, immune response, immunostimulant. ABSTRAKPenelitian ini bertujuan untuk menguji pengaruh penambahan ekstrak kasar spons pada pakan ikan terhadap pertumbuhan dan respon imun  non spesifik ikan nila (Oreochromis niloticus) serta menentukan dosis ekstrak kasar spons yang paling efektif dalam meningkatkan pertumbuhan dan respon imun non spesifik ikan nila (Oreochromis niloticus). Sampel spons dimaserasi kemudian dievaporasi menggunakan rotary vacuum evaporator sehingga diperoleh ekstrak kasar berbentuk pasta yang kemudian dicampurkan pada pakan. Ikan uji diberi pakan perlakuan 5% dari bobot biomassa selama 14 hari dengan frekuensi pemberian pakan dua kali sehari. Hasil penelitian menunjukan bahwa penambahan ekstrak kasar spons pada pakan ikan memberikan pengaruh yang baik terhadap pertumbuhan dan respon imun non spesifik ikan nila (Oreochromis niloticus), yang mana dosis yang terbaik adalah 40 gr / Kg pakan.Kata Kunci : Ekstrak spons, respon imun ikan, pertumbuhan ikan, respon imun, imunostimulan.

Materials Used

This study presents results from a life cycle assessment (LCA) conducted following the CML-IA method on caged aquaculture of Nile tilapia (Oreochromis niloticus) species at Como River, Kenyir Lake, Terengganu, Malaysia. In this study, the greenhouse gas (GHG) estimation, calculated based on the Intergovernmental Panel on Climate Change (IPCC) 2006 Guidelines, showed that 245.27 C eq (1.69 Kg) of nitrate oxide (N2O) was emitted from the lake. The determination of LCA was conducted using several inputs, namely N2O, compositions of fish feed, materials used to build fish cages (infrastructure), main materials used during operation and several databases, namely Agri-footprint, Ecoinvent 3, European Reference Life-Cycle Database (ELCD), and Industry Data 2.0. The results show that feed formulation is the major contributor to potential environmental impact in aquaculture farming, at 55%, followed by infrastructure at 33% and operation at 12%. The feed formulation consisting of 53% broken rice contributed to marine ecotoxicity (MET), while those consisting of 44% fish meal and 33% soybean meal contributed to abiotic depletion (ABD) and global warming (GW), respectively. It is recommended that the percentage of ingredients used in feed formulation in fish farming are further studied to reduce its impacts to the environment.
