One day workshop on Training Programme of Preventing Fish Diseases and their Management was given to the fish farmers in Kannan Fisheries Farm at Palakkad on 14.10.2017.
Dr. S. Binu kumari organizing Secretary of this programme from the Department of Zoology, Kongunadu Arts and Science college, Coimbatore-29 visited this Kannan fisheries farm at Palakkad. During this training programme, many farmers from that area participated and gained many practical knowledge with regard to different kinds of fish diseases and fish health monitoring.
Intensively cultured fishes are naturally susceptible to bacterial, fungal and parasitic infections, particularly at times of stress. Many problems can be avoided by appropriately quarantining new stock before release into culture tanks or ponds, maintaining water quality and a stress free environment and regular disease monitoring of stock. In the event of disease outbreak, stock can sometimes be effectively treated by salt or freshwater baths or via veterinarian prescribed treatments. There are some fish diseases and infections that can be transmitted from fish and the water in which they are cultured to humans. Although the infection of humans with fish pathogens is a relatively unusual event, it is a health risk that needs to be recognized by fish farmers and other people who handled the fish farm.
Managing a disease outbreak
Isolate any animals showing signs of disease or infection in separate ponds and tanks.
Quarantining all equipment from other ponds and tanks
Prevent birds, animals, vehicles and human from spreading disease through the farm
Tend to healthy animals each day before you have any contact with sick ones.
Collect specimens of affected aquatic animals for laboratory examination
Safely dispose of diseased and dead animals and effluent water.
The goal of the programme was making fish farmers to understand the incidence of transmission of disease from fish to humans is dependent upon several factors including the type of organism (Viral, Parasitic or Bacterial) of the host (immuno – compromised individuals, presence of open wounds) and environmental factors (quality of water, depth of penetration of fish spines). Optimum farm design, appropriate husbandry and handling and water quality management will reduce the risk of disease transfer from fish and their environs to workers in the aquaculture industry. Mainly fish farmers participated in the program and benefited.
