Executive summary

The welfare of farmed fish is a topic that is gaining exponential attention in research, public awareness, production and policy, since the impacts on the animals are reflected the whole sector. To address it correctly it is important to define the terms: welfare is the state of the animal as it copes with its environment. This definition enables the measurement of welfare through different indicators, which in turn allow the testing, validation and implementation of measures to improve the welfare and production of farmed fishes. The focus of Joao Saraiva’s (Fish Ethogroup) report is on the behavioural indicators of welfare, which represent the state of the animal very accurately.
