Vaccination

Fish vaccination is a key practice in modern aquaculture to prevent infectious diseases and ensure healthy population growth. It helps to reduce the use of antibiotics, enhance farm biosecurity, and promote a sustainable and responsible production system.

Vaccination is commonly used for sensitive species such as salmon, trout, or sea bass, and can be administered manually or through automated systems, depending on fish size and production scale.

Vaccination Methods

• Intraperitoneal injection (most common)

• Immersion: fish are bathed in a vaccine solution

• Oral: the vaccine is incorporated into feed

• Spray (aerosol): an emerging method for certain species or early stages

Benefits

• Effective protection against major bacterial and viral diseases

• Reduces mortality and improves growth rates

• Lowers the need for antibiotics and chemical treatments

• Improves sanitary and commercial quality of the fish

• Complies with traceability requirements and animal welfare standards

Applications

• Suitable for small and large farms

• Compatible with automated vaccination systems

• Can be integrated into biosecurity programs

• Vaccines available for various species and specific pathogens
