Meanwhile, local culinary traditions that were firmly in place until just a few decades ago, including the use of Dolphinfish(Coryphaena hippurus), are now disappearing. Therefore I would like to propose a reexamination of local fish species consumption. This would be a more efficient use of biological marine resources and also contribute to a revitalization of local culture.
