Maya would be ideal for fishing but then it would be over instantly.
Sal would probably tip the boat and kill the fish until there was nothing left but guts and blood in the water.
Gaige would shock the fish.. and let DT fly around with an umbrella to protect against foul bird droppings.
.. sadly Sal would use Zero as a human sword(to really drive the point in) and cut the fish over the side, it would be like a minigame "fast sushi" he would call it.. after, he would use zero as a toothpick.
Axton would probably look good in a fishing hat, beer and rod in hand chilling in wait of fish. He might use his turret to ward of potential bird competition.
