Video | Moria of blue crabs on the beaches of the Delta:the heat or the 'divine hand'?

Ulss and the Venice Zooprophylactic Institute have been alerted to understand the causes.In recent days the inauguration of the statue dedicated to Maria Stella del Mare in Porto Tolle.While the ecobiodefender appears.At what point is the fight against the "alien"?

BOLOGNA – Beaches transformed into blue crab cemeteries:this is what tourists, with their 'smartphones', have been filming since yesterday on the Veneto beaches of Polesine due to the sudden death of the famous alien crab caused, it is thought, by the high temperatures of the sea waters.In fact, videos of the beaches can be found on social media Boccasette, Scanno Cavallari And Stack, near Porto Tolle.Yesterday morning and today, Monday 29 July, many tourists who decided to spend a day at the seaside on the shores of the Po Delta reported the phenomenon with videos and posts.

The area affected by the die-off is a real trench area in the 'war' against the invasion of the blue crab which in just a few years has "wiped out" the main fish resource, that of clams.Just the Polesine fishermen's consortium he alerted Ulss and l'Experimental Zooprophylactic Institute of Venice to better understand the extent of the phenomenon, its extension and causes.In fact, confirmation is being sought that it could be a single event, due to the heat wave that brought sea waters to temperatures above 30 degrees, but we are also wondering whether something else could have caused it.

PRAYERS (ANSWERED) TO THE STATUE OF MARY STAR OF THE SEA

Meanwhile, among the inhabitants of Porto Tolle there are those who do not consider the phenomenon of the death of thousands of killer crabs precisely on these shores to be causal, but even a 'divine sign':only last Friday in fact, July 26th, in port of Pila, Porto Tolle, the statue dedicated to Maria Stella del Mare, commissioned and installed by the local fishermen's cooperatives, was officially inaugurated in the presence of civil and religious authorities.A curious coincidence, certainly, but completely without scientific basis.

What is certain, however, is the same Fedagripesca-Confcooperative in recent days it has launched a nationwide alarm for the rise in sea temperatures.And the fishermen of the north coast in Emilia Romagna, a Port Garibaldi– not too far from the Polesine beaches – they complain about having to consume more fuel because the fish go further out to avoid the heat near the coast.

ADVANCE IN THE FIGHT AGAINST THE ALIEN CRAB, “THE ECOBIODEFENDER” TICKS

Meanwhile, the ingenuity of three inventors of Mesola, in the Ferrara area, have instead developed a Ecobiodefender, a tool in the patent phase, on which there are high expectations of retaliation in the fight against the killer crab.Furthermore, the machine - according to local newspapers LaVoce di Rovigo and Il Gazzettino - is capable of containing the blue crab population in an ecological and bio-sustainable way.The creators report that after almost a year of experiments and tests they have built "a system that is positioned on the seabed, in stainless steel, of small dimensions".A sort of crab-eating machine that does not need external energy sources, but uses wave motion to function and can be positioned in "enclosures" where it is possible to breed clams safely because the machines would eliminate the "intruders".
