Monitoring of marine animals and mammals
In the area of the Saint-Brieuc offshore wind farm, several marine mammals live.
We find among these marine mammals, 2 large groups:
Dolphins, porpoises and even whales:
otherwise called cetaceans…
Seals :
otherwise called pinnipeds…
The particularity of these mammals is that they live mainly in the sea. They swim like fish but do not breathe like them! They have to come to the surface to be able to breathe.
Why do we need to protect marine mammals?
Their life is punctuated by important events: sleep, moulting , maintenance of the coat, birth, breastfeeding of the young, etc.
Getting close to them can scare them away and disrupt their life cycle. You wouldn't want to be woken up in the middle of your sleep, would you?

Measures to preserve fishing
Fishing and the wind farm
The bay of Saint-Brieuc is a place where scallops live and are fished. The wind farm was moved 6 km to the north so as not to disturb the scallops and fishing.

What is a scallop?
The scallop is a species of bivalve mollusc, this means that its shell is made up of two parts called the valves, connected by a ligament so that it can open.
It is recognized by its large size, up to 16 cm, as well as its fan-shaped shell. It moves over short distances, in leaps, by clicking its two valves. In the wild, it can live up to 20 years.
