Off to Marseille, where we meet up with Marine Fidelle, aquaculture manager for Ecocéan who manages the CascioMar project. This project is involved with the ecological restoration of the Mediterranean Sea by helping repopulate the species that are fished. The fishermen accompanied by Ecocéan are able to continue their activity in a sea with a fish population whose renewal is no longer threatened. We take a closer look in our feature "Protecting the planet one step at a time" with Energy Observer Solutions .
Rearing juvenile fish, in complete safety, before releasing them into the sea. Such is the solution put forward by CascioMar in a bid to replenish the lost biodiversity in a Mediterranean threatened by pollution and overfishing.
A shout of alarm
The planet is experiencing its sixth mass extinction in terms of its biodiversity. This disaster is directly related to human activity. This has a particularly heavy impact on the oceans, and human activity and pollution pose multiple threats to the marine environment: areas deprived of oxygen are becoming more widespread, the temperature of the surface water is increasing and the seas are becoming increasingly acidic. According to the WWF, marine fauna has halved in number since 1970.
The mission to rescue marine fauna
In the ports of Cassis, La Ciotat and Marseille in southern France, the members of Ecocéan catch fish larvae during their gestation period, a time when 95% of them die naturally. The ‘catch' is then reared in a nursery for four to six months, during which time the baby fish receive all the necessary care to ensure they develop as they should. Once the latter reach a ‘safe size' they are released back into their natural habitat. Since 2016, more than 40 species of fish have been reared in the nursery set up in the port of Marseille. Here, a fish larva has an 80% survival rate. In three years, the project has enabled over 5,000 young fish to be released back into the Mediterranean.
