Article of Association of the Biologists in the Business World: sustainable aquaculture

Jordi Carreras, biologist specialized in Aquaculture, member of the Board of of Biologists of Catalonia and friend of the XRAq since its inception, speaks to the Business World about sustainable aquaculture and makes an analysis of the present and the future of the sector:

Conserve and use sustainably the oceans, seas and marine resources for sustainable development.

The Final Declaration of the Kyoto protocol (1997) acknowledges that fisheries and aquaculture play a fundamental role in the adequate supply of food, especially aquaculture, being one of the main alternatives to maintain the proportion of fish in the diet world compared to the degradation of the marine environment and overfishing.

The dietary changes and the increase of the population allow us to intuit that by the year 2020 there will be some needs of 170 million tons of fish a year, of which it will be necessary to cover a deficit of 40 million with the breeding colony of aquatic species.

According to the United Nations Organization for Food and Agriculture (FAO), an extraction of fishery resources exceeding 100 million tonnes a year would have some negative consequences are irreversible on these goods marine. It is not that the fish are exhausted, but the selective pressure exerted by fishing extractive is concentrated in one out of every 1000 species aquâtiques, and these are the ones that can be in danger.

By understanding ourselves better, we should recall what is meant by aquaculture marine production of species of origin water, in any of its stages of the biological cycle, and controlling in some way these organisms and their environment.


From the year 1988 they have techniques for growing mediterranean fish, and although it is a business practice young, who has spent periods of uncertainty and wavering.installation, now is positioning itself as an activity of the future, capable of generating wealth, business and county.

Like all farming, aquaculture marine generated waste, but the authorities have been concerned that this sector is sustainable and has been equipped with the appropriate protocols for the environmental monitoring to control and decrease their possible impacts. Currently, the sector has defined criteria for the completion of environmental studies prior, the monitoring of this activity and the interpretation of results. Although the contents, design and execution of the Plans of Environmental Monitoring (PVA) of the farms marines can vary greatly.

To contribute to generate knowledge and provide solutions to a possible loss of competitiveness in companies and an inadequate strategy for environmental management for the administrations, the Ministry of Agriculture, Food and Environment has funded between 2008 and 2011, the National Plan “Selection of indicators, determination of reference values, design of programmes and protocols methods and measures for environmental studies in aquaculture, marine”. This project, with the participation of research centres in six autonomous communities, and 20 enterprises in the sector, has been aimed at establishing the bases on which to design protocols and plans for monitoring environmental impact of aquaculture, with the purpose of to facilitate the development of environmental studies required, and to simplify the administration of the environmental management relative to aquaculture marine.

For the sake of this young industry, we hope that all these difficulties will be overcome.
