Effect of Probiotic Bacteria Culture on Pathogenic Bacteria from Fresh Water Fish Oreochromis Mossambicus
Fish diseases are one of the major problems in fresh water biota. There is an urgent need in aquaculture to develop microbial control strategies, since diseases epidemics are recognized as important constraints to aquaculture production, trade and the development of antibiotic resistance has become a matter of growing concern. In this study, we evaluated the tilapia fish (Oreochromis mossambicu...

متن کاملFresh-water Fish Chemoreceptors Responsive to Dilute Solutions of Electrolytes
I N T R O D U C T I O N The palatal chemoreceptors of the carp display a rather peculiar type of response to varying concentrations of electrolytes (Konishi and Niwa, 1964). Dilute solutions of salts, especially those with polyvalent anions such as Na3citrate and Na 2 HP04 , produced strong responses. However, an increase in concentration depressed receptor activity, although the activity incre...
متن کاملToxicity of Nickel to Fresh Water Fish, Channa
Heavy metals are considered as the most important pollutants of the aquatic environment. In the present study, acute toxicity test was used for the determination of lethal toxicity of Nickel in adult fish, Channa gachua as the test organism. Toxicity test is most reliable for accessing the adverse effect of pollutants on aquatic life. The LC50 values were determined and observed that the values...
