Effect of dietary enhanced Moina macrocopa (Straus, 1820) on the growth, survival and nutritional profiles of hybrid Nile tilapia fry

Studies were carried out on the growth performance of Tilapia fry, Oreochromis niloticus cultured with zooplankton, Moina macrocopa in comparison to commercial feed. Three types of feed were used in three treatments where treatment-1 was fed with handmade feed (control), treatment-2 with commercial feed and treatment-3 with live zooplankton M. macrocopa. Thirty fry were stocked in each 60 L aquarium for a rearing period of 56 days. The fishes were fed twice a day at 90-400 Moina/individual fish for first 20 days, then 500-850 Moina/individual fish for 15 days and 900-1250 Moina/individual fish for remaining days. Sampling was done at 14 days interval. The growth performance of M. macrocopa was higher in the treatment fed with Spirulina which was 6350 individuals/ L of water and in the treatment fed with yeast it was 5100 individuals/L of water at 12th days. The study showed that condition factor of tilapia fry found in treatment-3 fed with M. macrocopa was comparatively higher (2.18±0.09) than that of treatment-2 fed with commercial feed (1.86±0.13) at a 56-day culture period. Average daily gain was significantly higher in the treatment-3 fed with M. macrocopa (0.13±0.01) than those of treatment-1 (0.06±0.01) and treatment-2 (0.08±0.01). The best value of feed conversion ratio and specific growth rate was found in treatment-3 fed with M. macrocopa than commercial feed and handmade feed. Protein content was significantly higher (15.91%) in treatment-3 than those of treatment-1 (10.96%) and treatment-2 (11.88%). The findings of this study suggest that growth parameters and body composition of Nile Tilapia was better in treatment-3 fed with M. macrocopa.Bangladesh J. Sci. Ind. Res. 52(2), 81-88, 2017

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.

Objective: To study the incidence and seasonal dynamics of different fungi affected freshwater fishes in Lake Manzala with molecular identification of the isolated fungi. Animals: 300 Nile tilapia (Oreochromis niloticus) and 300 catfish (Clarias gariepinus). Design: Descriptive study. Procedures: Random samples of Oreochromis niloticus (O. niloticus) and Clarias gariepinus (C. gariepinus) were collected from Manzala fish farms. Clinical and postmortem examination of fish was applied. Isolation and identification of different fungi were performed by conventional methods. Furthermore, the molecular characterization of isolated fungi was carried out. Results: C. gariepinus had a higher rate of infection with different fungal species than O. niloticus. Aspergillus spp. (Aspergillus niger and Aspergillus flavus) were the most fungal isolated from the examined fishes, followed by Penicillium spp. and Candida albicans. Aspergillus spp were detected in all seasons with a higher rate in summer and spring. A. flavus, A. niger, Penicillium spp. and C.albicans isolates were amplified from both C. gariepinus and O. niloticus at the specified molecular weight using PCR. Conclusion and clinical relevance: Fungal infection affected the fish showing different external and internal lesions, all species of Aspergillus were found in all seasons with a high rate in, hot seasons, summer and spring. The Prevalence of Penicillium and C. albicans were also reported. All fungal isolates were identified on the phenotypic and molecular bases.
