Implementation of effective stunning methods for all fish species, ensuring immediate loss of consciousness before slaughter. Methods such as properly applied electrical stunning and controlled hypoxia are highly recommended, while air asphyxiation, bleeding without prior stunning, thermal shock in ice, or the use of carbon dioxide should be prohibited due to the cruelty involved.

Overcrowding in cages and ponds generates chronic stress in fish, weakening their immune systems and increasing disease spread. Limiting fish density is essential to allow natural behaviors, reduce aggression, and improve water quality. Regulations must specify clear limits by species and environmental conditions, tailored to each fish’s biological needs.

Housing must meet fish welfare needs, allowing them to exhibit their natural behaviors as much as possible. Appropriate substrate and shelter must be provided for different species.

Fish welfare is directly linked to the water quality they live in. Parameters such as dissolved oxygen, temperature, pH, and ammonia levels must be kept within specific ranges to avoid stress and disease. The use of automated systems for continuous monitoring and alerts for sudden changes is recommended. Moreover, rapid response protocols must be in place to correct issues that could affect fish welfare.

Transport is one of the most stressful stages for fish, due to factors like handling, temperature fluctuations, and reduced oxygen. It is proposed to limit the maximum travel time, set standards on water volume per fish, and require vehicles equipped with oxygenation and temperature control systems.

Handling of fish, especially out of water, should be minimized. Methods such as using dry nets (for transport, slaughter, treatments, farm transfers, or other purposes) must be avoided.

Practices such as tagging, fin clipping, and evisceration are often performed without anesthesia, causing avoidable pain and suffering. We propose banning these procedures without the use of appropriate anesthetics and techniques that minimize pain.

Require specific training for workers in respectful handling techniques, identification of stress signs, and the use of technologies that minimize fish suffering.

Create a set of specific indicators, such as growth rates, mortality, abnormal behavior, and stress response, to objectively assess fish welfare. These indicators must be measurable and adapted to each species, with mandatory monitoring in all fish farms.

Implement frequent inspections by independent bodies to verify compliance with animal welfare regulations at all aquaculture facilities, covering every production stage from handling to slaughter. Inspection reports must be public to ensure transparency.

The industry must invest in research projects aimed at developing new technologies and methods to improve fish welfare, especially regarding handling and slaughter, and promote studies on species-specific behavior and needs, facilitating the adoption of more ethical and efficient practices.

Establish a clear and transparent labeling system to inform consumers about the level of animal welfare in fish product production, encouraging more ethical practices and enabling consumers to make informed and responsible choices. This labeling must be verifiable, regulated by independent entities, and accurately reflect the conditions under which fish are bred, handled, and slaughtered. Regarding transparency, competent bodies should also count fish in fisheries and aquaculture production by number of individuals rather than tons, and periodically collect and publish data on welfare indicators including disease incidence and mortality rates.
