Abstract

The research with the aim to know the effectivity (yield gap) of the application of Streptococcus agalactiae vaccine (pure whole cell) in prevention of streptococcosis on tilapia (Oreochromis niloticus) culture has been carried out. The isolate of S.agalactiae – N14G was used as a master seed on vaccine production. Priming vaccination was administered by immersion method, and booster vaccination was taken th place two months latter by oral method. Challenge test at the lethal dose (LD50) against active bacteria was done at 14 days post booster vaccination, and observation was taken place for 14 days post artificial infection. The results of the research showed that the highest survival rate and relative percent survival (RPS) was found in group treated with Streptovac vaccine (S. agalactiae and A. hydrophila combination) (65.58% and 35.36%) followed by S. agalactiae vaccine (52.08% and 10.01%). The lowest survival rate was found in control group (46.75%). The result of confirmation effectivity of the vaccines by challenge test in the laboratory showed that the highest survival rate and relative percent survival (RPS) was found in S. agalactiae vaccine (50.00% dan 37.50%) followed by Streptovac vaccine (40.00% and 25.00%), and the lowest survival rate was found in control group (20.00%). Vaccination is better than the non vaccinated.

Abstract

Vitamin E merupakan salah satu mikronutrien penting yang berpengaruh terhadap performa reproduksi ikan. Penelitian penambahan vitamin E dalam pakan induk ikan nila (Oreochromis niloticus) bertujuan untuk mengetahui pengaruh vitamin E terhadap perkembangan gonad dan performa pemijahan induk ikan nila. Pakan uji yang digunakan adalah pakan formula dengan kadar protein 35% dan lemak 10% ditambahkan vitamin E (tingkat kemurnian 50%) dengan dosis A) 0, B) 75, C) 150, D) 225, E) 300 and F) 375 mg/kg pakan (kontrol). Induk ikan nila umur 6-7 bulan sebanyak 180 ekor dipelihara dalam 6 jaring ukuran 3x3x1,5m yang diletakkan dalam kolam 6000 m2 dengan kedalaman air 80 cm. Masing-masing jaring diisi dengan 20 ekor induk betina dan 10 ekor induk jantan dan dipelihara selama 13 minggu pada bulan September sampai dengan November 2011. Hasil penelitian menunjukkan bahwa penambahan vitamin E pada pakan induk ikan nila memberikan nilai indeks gonad somatik lebih tinggi dibandingkan yang kontrol. Penambahan vitamin E sebanyak 225 mg/kg pakan memberikan nilai persentase induk matang gonad yang tertinggi (80%) dan frekuensi pemijahan yang terbanyak yaitu 22 kali selama masa pemeliharaan 13 minggu. Berdasarkan hasil penelitian yang diperoleh dapat disimpulkan bahwa penambahan vitamin E sebanyak 225 mg/kg pakan dapat meningkatkan perkembangan gonad, jumlah induk betina yang matang gonad, persentase total pemijahan dan frekuensi pemijahan pada induk ikan nila.

Abstract

An experiment with the aim to identify the cause of disease in Indo-Pacific bottlenose dolphins, Tursiops aduncus was conducted in Pathology Laboratory of Institute for Mariculture Research and Development, Gondol, Bali. The diseased fish showed lost appetite, swim slowly, and haemorrhage on the body surface. These clinical signs indicate that the fish infected by bacteria. The bacteria then were isolated aseptically from different parts of fish body including chin, abdomen, dorsal and caudal fins. Some media were used to isolate the bacteria, namely Triptic Soy Agar (TSA) as a general medium, Thiosulphate Citrate Bile Salt Sucrose Agar (TCBSA) for Vibrio bacteria, Cytophaga Agar (Cyt-A) for Flexibacter bacteria, and KF-Strep Breeders media for Streptococcus bacteria. As a result, one dominant bacterium was isolated from TSA and TCBSA. No bacteria growth showed on Cyt-A and KF-Strep media.The isolate was gram-negative, fermentative, swarm on TSA, growth with yellow colony on TCBSA. Based on its characteristics the isolate identified as Vibrio alginolyticus. Minimum inhibitory concentration (MIC) against Vibrio alginolyticus were 1 ppm for Nifurpirinol, 5 ppm for Penstrep, and 10 ppm or Elbaju.
