CIFA M-Check for External Injuries Caused by Argulus or any Secondary Pathogens in Fish

Background
Infectious diseases are a major bottleneck for aquaculture development. To date, there are
very few proven preventive or treatment measures available against any aquaculture diseases.
Secondary infections caused by opportunistic pathogens are the most common form of disease
occurrence in aquaculture farms. Further, argulus-mediated external injuries are one of the
major reasons for secondary infections and its associated mortality and morbidity. Repeated
use of broad-spectrum chemicals and pesticides makes pathogens resistant in subsequent
applications. To treat the external injury associated with argulosis and secondary bacterial
infection, CIFA M-Check is developed which can effectively control various secondary bacterial
infections effectively in single application during Argulus infection. In addition, Both L-Check
and M-Check in combination have shown great potential for the treatment of argulosis and its
associated external injury and secondary infections in wet-laboratory conditions and in
farmers’ fields. Three potential antimicrobial ingredients (Component A, Component B and
Component C) were mixed in an optimum combination to develop the final product i.e. CIFA
M-Check. The product heals the ulcerative lesions caused by argulus within three to five days
very effectively. The mortality is also reduced drastically with its application
Technology Details
Three potential chemical ingredients (Component A, Component B and Component C) were
mixed in an optimum combination to develop the final product i.e. CIFA M-Check. A single
application of CIFA M-Check can effectively control argulus ulcers in fish, if it is at the initial
stage of infection. It has also been noticed to heal bacterial infections or ulcers in fish and
prawn. In addition, CIFA L-Check treatment should be followed by the CIFA M-Check application
for the treatment of external injury and secondary infection caused by argulus. It has been
tested both in wet laboratory and more than twenty farmer’s field and found to be very
