When the fishermen saw how much the bear cubs were shivering, they decided to not just leave them on land but to search for the mother bear as well. She couldn’t be far, after all. It was clear to the fishermen that they couldn’t simply abandon the cubs. There were foxes and other wild predators in the area as well, and those might see the cubs as prey.
First, they had to find a suitable spot to take the cubs off the boat. They didn’t know how the mother bear would react when they saw her. A grown-up bear is very big and dangerous. Nevertheless, the fishermen carefully steered towards the spot where the mother bear was.
