The Fishermen Needed a Better Solution
Now that the cubs were safe, the fishermen needed to figure out what to do with them. After all, these were wild animals that belonged in the wilderness. And since they were young, they still needed their mother. So, the fishermen figured that they had to do something to reunite the cubs with their parent, even though she had left them behind. The mother was probably hoping to bring food back for the bears who she could no longer carry with her.
