There is an urgent need in aquaculture to develop microbial control strategies, since disease are recognized as important constraints to aquaculture production, trade and the development of antibiotic resistance has become a matter of growing concern. One of the alternatives to antimicrobials in disease control could be the use of probiotic bacteria as microbial control agents. Twenty five strains were isolated from pond water and pond soil. Five isolates obtained by screening of twenty five isolates and used for further studies,The study indicates that the addition of yeast sludge waste is...

The water samples were collected for the isolation of strains of alga Spirulina platensis from three different locations and the strain Spirulina platensis was isolated and it was, designated as ANS - 1 strain. The characteristics of Spirulina platensis ANS -1 were compared with reference CAS -10. The isolated strain ANS -1 and reference strain CAS 10 were grown in substrates 1/6 diluted Zarrouk's medium (control), Rice mill effluent and sago industrial effluent.The effect of temperature and pH was determined for the strains CAS - 10 and ANS -1, and highest biomass was observed at 30 C of pH...
