This champion fisher will be rewarded in-kind for returning with the first catch. Those who aren’t able to return with the first catch will still receive just reward for getting the Blacktip Shark to Elder Clearwater before he takes his leave. It is said that these sharks’ favorite meal are the bite-sized Pygmy Suckerfish. Perhaps a hook in their waters will do the trick.
