Analysis of Microbial Contamination in Oreochromis Niloticus in Waduk Muara Nusa Dua
SEAS (Sustainable Environment Agricultural Science), 2020Co-Authors: Ni Kadek Peniasih, I Gede Suranaya Pandit, Dewa Gede Semara EdiAbstract:This study aims to determine the microbiological contamination in the main water source of the Muara Nusa Dua Reservoir, the Tukad Badung River, and to determine the microbiological quality of fresh Oreochromis niloticus caught in the Muara Nusa Dua Reservoir in Denpasar. The study was conducted in May-August 2019 at the Denpasar Veterinary Laboratory. The method used is a descriptive method that aims to describe or describe the condition of the Tukad Badung watershed which empties into the Muara Nusa Dua Reservoir (Estuary Dam). Objective tests include the total bacterial test, the Coliform test, and the Escherichia coli contamination test. Water quality measurements are also carried out as supporting data from this study. The results of the study stated that there was microbiological contamination in the water source of the Muara Nusa Dua Reservoir, the Tukad Badung river, which also had an impact on the waters of the Muara Nusa Dua Reservoir. Microbiological contamination research results showed the microbiological quality of ten samples of Oreochromis niloticus in the form of the highest total bacteria was at 2.2x104, the highest total Coliform was 1.9x104 and the highest Escherichia coli contamination was at 93 APM / g with an average reservoir water quality Muara Nusa Dua in the form of temperature 27.3 °C, salinity 0.208 ‰, degree of acidity (pH) 6.5, dissolved oxygen (DO) 5,97 ppm. Organoleptic observations included the appearance, smell, and texture of Oreochromis niloticus with good results because when testing Oreochromis niloticus is still alive

production en masse d alevins mâles de tilapia Oreochromis niloticus de la vallee du fleuve senegal a partir de l aliment hormone au 17 alpha methyl testosterone
International Journal of Biological and Chemical Sciences, 2019Co-Authors: Momy Seck, Hamet Diaw Diadhiou, Papa Demba Ndao, Theophile Diouf, Abdoulaye NianeAbstract:Cette etude a ete realisee en 2017 a la station de l’Agence Nationale de l’Aquaculture de Richard-Toll (vallee du fleuve Senegal) dans le cadre du projet PISCI/FNRAA/WAAPP2 Commandite sur l’Adaptation, Diffusion et Adoption de technologies de production en masse d’alevins mâles de Tilapia ( Oreochromis niloticus ) au Senegal finance par le Fonds d’Impulsion de la Recherche Agro-Alimentaire du Senegal (FNRAA). Face a un deficit d’alevins de tilapia confronte par les producteurs et a la difficulte de sexage manuel, ce travail oeuvre a produire et fournir en quantite suffisante des alevins mono-sexe mâles de qualite aux producteurs et de transferer la technologie aux agences d’execution de l’aquaculture et aux promoteurs prives. Pour ce faire, une activite de production en masse d’alevins mâles de la souche locale du Tilapia du Nil de la vallee du fleuve Senegal a ete testee en ajoutant l’hormone 17 alpha methyl-testosterone dans l’aliment fourni a des alevins dont le sac vitellin vient d’etre resorbe pendant 28 jours. Cette experience a permis de produire 21 168 alevins mâles de Tilapia ( O. niloticus ) en 3 mois et de cerner les limites de la production en masse d’alevins de la souche du Tilapia du Nil de la vallee du fleuve Senegal au niveau de l’ecloserie de l’ANA installee a Richard-Toll. Par consequent, cette etude peut etre reconduite en utilisant d’autres methodes d’inversion sexuelle du Tilapia. Mots cles: Tilapia, Orechromis niloticus, 17 alpha methyl-testosterone, inversion sexuelle, alevins mâles, aliment hormone.

complete mitochondrial dna sequences of the nile tilapia Oreochromis niloticus and blue tilapia Oreochromis aureus genome characterization and phylogeny applications
Molecular Biology Reports, 2011Co-Authors: Anyuan He, Hong Yang, Sifa Li, Chenghui WangAbstract:Cichlid fishes have played an important role in evolutionary biology and aquaculture industry. Nile tilapia (Oreochromis niloticus), blue tilapia (Oreochromis aureus) and Mozambique tilapia (Oreochromis mossambicus), the useful models in studying evolutionary biology within Cichlid fishes, are also mainly cultured species in aquaculture with great economic importance. In this paper, the complete nucleotide sequence of the mitochondrial genome for O. niloticus and O. aureus were determined and phylogenetic analyses from mitochondrial protein-coding genes were conducted to explore their phylogenetic relationship within Cichlids. The mitogenome is 16,625 bp for O. niloticus and 16,628 bp for O. aureus, containing the same gene order and an identical number of genes or regions with the other Cichlid fishes, including 13 protein-coding genes, two rRNA genes, 22 tRNA genes and one putative control region. Phylogenetic analyses using three different computational algorithms (maximum parsimony, maximum likelihood and Bayesian method) show O. niloticus and O. mossambicus are closely related, and O. aureus has remotely phylogenetic relationship from above two fishes.
