Although welfare protocols for fish have been developed in the past, indicators are species specific and peer-reviewed journals do not contain any tilapia welfare protocol assessments.  The new tilapia welfare assessment protocol was disaggregated into four aspects: health, environment, behaviour and nutrition. If any problem regarding any of these aspects is found, actions need to be taken to improve it, resulting in better welfare. The researchers behind a practical welfare assessment protocol for tilapia production in Brazil hope it can act as a framework for the implementation of a welfare management system that can be applied by tilapia farmers around the world. The same framework is currently being applied in China and Thailand, while protocols and standards for shrimp and carp are also being developed.
