An assessment of the nutritive value of the waste slurry of the African locust bean, Parkia biglobosa as an energy source in practical diets for tilapia was carried out in glass aquaria. Five diets (35% crude protein) were formulated in which yellow maize was replaced at varying level with parkia slurry waste as follows: Diet 1, (100% slurry), diet 2, (100% yellow maize); diet 3 (75% slurry, 25% yellow maize), diet 4 (50% slurry, 50% yellow maize), diet 5 (25% slurry, 75% yellow maize). Growth performance and nutrient utilization of the fish were based on average daily weight gain (ADG), specific growth rate (SGR), feed conversion ratio (FCR), and protein efficiency ratio (PER). Good growth and feed utilization efficiencies were obtained in all diets, however diet 5 had significantly better growth and food utilization with the highest average daily weight gain (ADG) of 0.60, SGR (2.32) and PER (3.05% per day). Difference in SGR were not significantly different between all diets. The result showed that parkia slurry was better utilized by tilapia fish in diets 3 and 5 where their replacements were neither wholly nor equal.

This study aims to apply vaccination against bacterial disease. The purpose of vaccination is to trigger the immune respone both non-specific and specific of fish against bacteria Motile Aeromonas Septicaemia (MAS) caused by Aeromonas hydrophila. The vaccination for fish with different ages: 2-3 weeks and 5 weeks were done using immersion method. The fish were re-vaccinated (booster) after two weeks of the first vaccination. The survival rate was < 50 % for juveniles 2-3 weeks and > 50% for juveniles 5 weeks. Survival rate for juveniles 5 weeks was higher than juveniles of 2-3 weeks. This shows that organs of juveniles of 5 weeks were more complete than the 2-3 weeks juveniles. The age of fish is one of the important factors for successfully vaccination. Penelitian ini bertujuan untuk melakukan penerapan vaksinasi terhadap penyakit bakterial. Vaksinasi ditujukan untuk merangsang respon kekebalan non- spesifik dan spesifik pada tubuh ikan terhadap penyakit Motile Aeromonas Septicaemia (MAS) yang disebabkan oleh bakteri Aeromonas hydrophila. Vaksin diberikan pada benih ikan nila yang berbeda umur yaitu 2-3 minggu dan 5 minggu dengan menggunakan metode perendaman. Ikan divaksinasi ulang (booster) setelah 2 (dua) minggu dari vaksinasi yang pertama. Prosentase kelangsungan hidup < 50 % untuk benih umur 2-3 minggu dan > 50% untuk benih umur 5 minggu. Jumlah kematian benih umur 2-3 minggu lebih tinggi dari 5 minggu. Hal ini menunjukkan bahwa fungsi organ benih umur 5 minggu telah lebih lengkap dari pada benih umur 2-3 minggu. Umur ikan merupakan salah satu faktor penting penentu keberhasilan suatu kegiatan vaksinasi.
