Reacción a "Expansion of marine aquaculture may denature oceans"

The studies are well-founded scientific works and describe a number of risks to aquaculture. However, in my view, there is a certain bias. For example, disadvantages to human health are cited, such as the accumulation of toxins or microplastics. That is true, but what about wild fish? Evidence shows that toxic accumulation is higher in wild fish, among other things because the sea has been the dumping ground for mankind and there is a bioaccumulation effect in the food chain, whereas aquacultured fish are fed with previously analysed, traceable and toxic-free material. Like this there are many points to discuss in these papers. These studies identify the risks of aquaculture, which is essential to remedy them, but it is also true that aquaculture is constantly working to become more sustainable, avoiding and overcoming these risks.

Today, from my point of view, both aquaculture and livestock farming are necessary, or more precisely, indispensable, but we must bear in mind that there are animal production systems that are not sustainable and others that are. That is where the real issue lies: we must define and implement animal production systems that are integrated into a circular economy.
