Abstract:
The issue of Running Mortality Syndrome (RMS) in shrimp farming is a cause for concern as it can lead to significant economic losses. RMS is primarily caused by the Vibrio parahaemolyticus bacteria strain. RMS is characterized by reddening of body with reddish hepatopancreas and mortality started from 40 days of culture (DOC). In a recent study, advanced molecular techniques were used to isolate and identify the causative organism as Vibrio parahaemolyticus. Histopathological analysis revealed vacuolation of B cells, sloughing into the lumen of hepatopancreas, muscle necrosis, edema, and haemocytic infiltration in infected shrimp. Ayapana triplinervis was studied against Vibrio parahaemolyticus isolated from RMS infected shrimp and compared with Oxy-tetracycline (OTC) as a positive control by MIC test. Therefore, the use of Ayapana triplinervis as a potential herbal antimicrobial agent can be considered as a viable option for the control of the causative agent in the shrimp production sector, as part of eco-friendly and sustainable management practices.
