The work seeks to identify and categorise the different types of impacts of marine aquaculture through the analysis of previously published scientific data. The aim is to help in decision-making on the viability and usefulness of this activity. The treatment of the data is adequate and the description of the different types of impact can be useful for this type of management.

However, the authors' suggestion that marine aquaculture does not represent a solution for global food security cannot be deduced from the data obtained in this study alone. In this regard, it should be borne in mind that aquaculture accounts for more than half of the marine species we consume (according to the FAO) and, at the marine level, it is the only way to increase food production without adding additional pressures on fisheries. On the other hand, this statement does not seem to take into account the progress made to mitigate its negative effects (both scientific and legislative).

In this sense, the current situation could be summarised in a sentence from a recent review (Troell et al., 2023): ‘Aquaculture is not the miracle solution for global food security or for achieving the Sustainable Development Goals, but it can make important contributions if properly planned and implemented'.
