SOS for the dolphins of the Ionian

Inappropriate fishing and indifference deprive the cetaceans of their food and threaten them with extinction

The mistaken way man perceives the exploitation of catches, which he considers to be inexhaustible, has in recent decades caused not only the disappearance of dolphin food but also a serious problem in the population of other species such as swordfish and tuna.

Catalan Johan Gonsalow, a biologist with a PhD in Biodiversity from the University of Barcelona, ​​has been researching the issue of cetaceanmigration in the Ionian Sea over the past few years through his collaboration with the Tethys Research Institute based in Civic Aquarium in Milan, Italy Member of the Board since 2007.

According to Documento Gonšalo, “the lack of food of this species of dolphins due to intensive fishing disrupted the balance of the marine mammal population in recent decades, caused the population to decline and the movement of those who remained from the central Ionian to the north” .

“Part of the dolphins that were lost over the past decades we found them a few years ago in the Corfu region where they may have found better conditions to live. Indeed, in 2010 we recorded 30 common dolphins between Corfu and Paxos. In our research we found that some of them were formerly residents of the Ionian area where the problem of dramatic population decline had been identified initially, “says Alexandros Frantzis, Biological Oceanography, director of the Institute of Pelagic Cetacean Research and Scientific responsible and coordinator of the National Census Record and Cetacean Records (www.pelagosinstitute.gr).

There were only 17 …

Dr. Frantzis estimates – as well as from cross-checks of previous years’ research data – that today the entire dolphin must be 45 to 50 and the Ionian is only 20 in the Ionian Sea.

The dramatic decline in the dolphin population was first detected and recorded in 1993. It was the year that scientists observed that while the dolphins in question were crowded in the section between Lefkada, Kefalonia, Ithaca, Zakynthos and across the coasts of Aitoloakarnania and the the coasts of Ilia suddenly began to drop dramatically.

While initially their population exceeded 250 people, suddenly in 2007 Greek and Italian scientists remarked with awe that this species of dolphins disappeared at an extremely fast pace. Photo scientists have found that the dolphins that remained in the Ionian Sea were 40, then dropped to 25, and at the end they were only 17 and restricted their activity south of Lefkada.

Protected area

“Thanks to these and many other observations and observations we managed to persuade the Greek state to announce a Natura 2000 marine area around Paxos – Antipaxos and southern Corfu and to unite it with the land of Thesprotia. Declaring the area to a protected area is very important for maintaining the dolphin population. However, there is a much older Natura 2000 area inside the Ionian Sea, where, despite our observations, no measures have been taken to protect dolphins! So until now the protection of this species is only on paper, so the problem and the risk of their disappearance remain, “Dr. Frantzis points out in Documento, pointing out: “Every time we come as scientists confronted with the risk of the extinction of a marine species, our heart breaks down as millions of years have elapsed to create this population, and nature has done millions of experiments in the evolution of these times to eventually end up and place the species in his place. The damage we do to nature is irreparable and it will slowly begin to affect human life as well. We will all face great and unpleasant surprises if we do not change mentality as societies, as states and as citizens … ” The damage we do to nature is irreparable and it will slowly begin to affect human life as well. We will all face great and unpleasant surprises if we do not change mentality as societies, as states and as citizens … ” The damage we do to nature is irreparable and it will slowly begin to affect human life as well. We will all face great and unpleasant surprises if we do not change mentality as societies, as states and as citizens … ”
