This item can be fished in the sea waters of Darkshore. While it is the objective of a quest, it is not a quest item per se, and can be caught while not on the quest.
Darkshore Grouper as a quest objective
This item is an objective of 
[14] The Family and the Fishing Pole, which rewards the fisherman with the [Blump Family Fishing Pole].
It is worthwhile to pick up the [12] Gaffer Jacks fishing quest from Wizbang Cranktoggle on the second floor in the Inn and do them concurrently. Both require random catches from the same water.
