Kegiatan budidaya pada setiap prosesnya menghasilkan limbah yang dihasilkan dari sisa-sisa pakan dan kotoran yang berasal dari ikan budidaya, terutama budidaya Ikan Nila yang merupakan salah satu jenis ikan tawar yang sudah di budidaya secara komersial oleh masyarakat indonesia. Penelitian dilaksanakan pada Mei-Juni 2017 di Laboratorium Pengelolaan Sumberdaya Ikan dan Lingkungan, Departemen Sumberdaya Akuatik, Fakultas Perikanan dan Ilmu Kelautan, Universitas Diponegoro. Pada penelitian ini ditambahkan enzim pada pakan ikan, suatu enzim yang mengandung protease, lipase, amilase, pepsin, tripsin, dan kemotripsin dalam dosis yang sudah ditentukan untuk memaksimalkan proses pencernaan. Ikan Nila yang digunakan  berukuran 7-9 cm dipelihara di dalam akuarium dengan kapasitas 2 ekor Ikan Nila dalam 1 akuarium dengan volume air 9 l. Tujuan penelitian untuk mengetahui konsentrasi amoniak, nitrit, dan sulfida (H2S) dan membandingkan pengaruh pemberian enzim dengan konsentrasi yang berbeda didalam pakan terhadap konsentrasi amoniak, nitrit, dan sulfida (H2S). Metode yang digunakan adalah metode eksperimental skala laboratorium. Desain penelitian berdasarkan rancangan acak lengkap (RAL), dengan menggunakan lima perlakuan yaitu dengan perbedaan konsentrasi enzim. Setiap perlakuan dilakukan 3x pengulangan. Analisis data menggunakan uji two way anova. Hasil penelitian menunjukkan bahwa pemberian enzim dengan konsentrasi berbeda tidak berpengaruh nyata, lama waktu pemeliharaan berpengaruh nyata terhadap konsentrasi amoniak, dan sulfida, kombinasi dari keduanya tidak berpengaruh nyata terhadap konsentrasi amoniak, nitrit, dan sulfida. Cultivation activities in each process produce waste generated from the remnants of feed and feces from the fish cultivated, especially the cultivation of tilapia which is one type of fresh bonds that have been cultivated commercially by the people of Indonesian. The research was conducted in May-June 2017 at the Fish and Environmental Resource Management Laboratory, Aquatic Resources Department, Fisheries and Marine Science Faculty, Diponegoro University. The materials on this research are combining the fish feed with an enzime which contains protease, lipase, amylase, pepsin, trypsin, and chemotrypsin in prescribed doses to maximised the digestion process. Tilapia as research object has length of 7 to 9 cm and its kept in an aquarium with capacity (water volumes) of 9 ls which contains of 2 tilapias. The purposes of this research are to know the concentration of ammonia, nitrite and sulfide (H 2 S) in and to compare the effect of the enzyme provision with different concentration in fish feed with the concentration of ammonia, nitrite and sulfide (H 2 S). This research used laboratory-scale experimental method. The study design was based on Complete Randomized Design (RAL), using five treatments with different enzyme concentrations. Each treatments was done by three repetitions. The data was analysed using two-way ANOVA test. The results showed that enzyme with different concentration had no significant effect, maintenance time had significant effect on ammonia concentration, and sulfide, the combination of both did not significantly affect the ammonia, nitrite and sulphide concentration.

Aflatoxin contamination, particularly common in cultured fishes in Asian countries, are considered unsafe both for fish and human health. However, the presence of aflatoxin in cultured fish feed and their effect are still under estimated in Bangladesh. The present study aimed to assess the effects of aflatoxin on growth performance and residues in tilapia (Oreochromis niloticus) fingerlings. Fish feed were treated with several concentration of aflatoxin as 0 ppb (T0, control), 25 ppb (T1), 50 ppb (T2) and 100 ppb (T3) and fed the tilapia fingerlings (n=10) in individual glass aquaria (24×12×12 inch, 105-litre capacity) conditions for 12 weeks. Comparatively higher body length (cm) and weight gain (g) were observed in treatment T0 (1.68 and 4.98) and T1 (1.60 and 5.48) than those of treatment T2 (1.31 and 4.06) and T3 (1.20 and 3.10), respectively. The specific growth rate (SGR) were almost similar in treatment T0 (52%), T1 (51%) and T2 (52%) whereas declined significantly (p<0.05) in T3 (39%). Higher survival rate was also demonstrated in treatment T0 (90%) and T1 (90%) whereas significantly decreased in treatment T2 (60%) and T3 (40%). The residue of aflatoxin was not detected in T0 and T1. On the contrary, the residual effect in tilapia fingerling was evident in T2 and T3 treatment. The findings of the present study revealed that aflatoxin contaminated feed is harmful for the growth performance and survival of O. niloticus fingerlings. Further study is necessary to safeguard the aquaculture production as well as to produce healthy food for human consumption.

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
