Isolation of Lactic Acid Bacteria from Intestine of Freshwater Fishes and Elucidation of Probiotic Potential for Aquaculture Application.

Probiotics play significant roles in enhancing systemic immunity, improving intestinal balance and feed value, enhancing enzymatic digestion, and inhibiting pathogenic microorganisms of freshwater fish. Probiotics from an identical organism's gastrointestinal system promote effective colonization and provide greater benefits than other sources. This study aimed to evaluate the usefulness of probiotic bacteria isolated from the intestines of freshwater fishes for a dietary supplement of freshwater aquaculture.

Identification and characterization of virulent Ah17 from infected in river Cauvery and in vitro evaluation of shrimp chitosan.

, an inhabitant in the aquatic ecosystem is considered as an important foodborne bacterial zoonotic pathogen in aquaculture. The present study aimed to identify virulent from naturally infected in river Cauvery and in vitro evaluation of shrimp chitosan. Rimler Shotts (RS) and blood agar medium identified the presence of pathogenic sp.

Determination of lethal dose of Aeromonas hydrophila Ah17 strain in snake head fish Channa striata.

Aeromonas hydrophila is a major bacterial fish pathogen which causes economic losses in the aquaculture. The study determined the Letha Dose (LD) of A. hydrophila Ah17 strain (isolated from EUS infected Channa striata) in C.
