Hope you like the following Pet Forest guide which selected from the other website by me, but it's not my work, Goldicq just give it a summary. Hope it can help you some.

Got tired of the regular fishing already and want to go up to the next higher stage? Well, Fishing Mastery is waiting for you then. It's for players who've at least reached Character Level(Pet Forest Gold) 45 and own a Fishing Certificate to be qualified as participant there.

Great prizes await you here, which are far more worth than what you'd normally get from regular fishing starting with Fish worth some Silver to Scallops and Halfbeaks, which'll reward you with a nice XP Boost or the two most precious fish out in Jade Dynasty which everyone is eagerly trying to catch and is the main goal of this competition. You can win the Silver. Gold(Pet Forest Gold) Medal to exchange for great prizes.
