Fishing is in a pretty dormant situation - With all the hard work getting the likes of the Ebisu + 1 / Lu Shangs +1, can we get some more reward offered from it please?

I was thinking a long the lines of:

1. With the hundreds of different fish in the game, can we expand on the Zaldon system? Example: Offer a chance at an updated pool of useful/valuable items that can be found by gutting the fish?

2. The addition of more RoE's if possible.

Thanks.
