dolphin fish video

Okt 19, 2017 | CERES News

In this popular TV program of the Balearic Islands “People from the sea”, which is on every Sunday night, I.Catalán went out with local fishermen during a typical fishing day devoted to the storyline of dolphinfish. The fishing day consists on departing well before sunrise and head towards the floating aggregating devices (about 40 for each fishing boat) which concentrate juvenile dolphinfish during the months of (end of ) August-December.

During the show, I.Catalán explained to the general public (many fishermen and people used to conduct activities at the sea) the goal of CERES project, the specific goals of CSIC and the particular case of dolphinfish. Many questions were raised by the presenter, including basic scientific knowledge on the species and its fishery, but also the potential impacts of climate change on distribution, growth and economy. Some very interesting messages conveyed in the interview were the absolute need to interact with fishermen to define future scenarios and potential strategies for adaptation/mitigation. I. Catalán asked the fishermen how or if they perceive climate change impacts in their activity, and explained that although gradual changes are difficult to grasp, perhaps they noted some effect of extreme heat waves or new species in the area. Indeed, they said that this 2017, one of the warmest years recorded, they noted larger juveniles on average….of course that is just an opinion!
