The presence of whales in the rich biodiversity of the Garraf coast near Sitges – as well as along the entire Catalan coast – has increased the risk of collision between marine animals and merchant ships using the Mediterranean.
During Spring, the common whale – also known as the 24-metre-long fin whale – approaches the shore for food. They are the largest whales to cross the waters of the Mediterranean.
A study by the Edmaktub Association published in the journal Frontiers showed April as the month with the highest risk of collision, with impacts between whales and cargo ships being the most common.
This year, in addition, the rainy weather in March caused the presence of whales in April to increase compared to previous years. It has become necessary to take measures to regulate maritime traffic in order to preserve the common whale and protect its integrity while feeding on the Garraf coast, the association has said.
As an imminent measure, Edmaktub has implemented a study which, through the installation of thermal cameras, aims to investigate the possibilities of detecting whales in order to avoid or reduce impacts with boats.
