With use of the recyclable bait, players never need to bank. It can also be stored in the Toolbelt. That said, if catching a certain type of fish as part of the challenge system, you need to bank that type of fish as the quartermaster will need to take those off of you.
On 6 January, 2009, Barbarian fishing became slightly slower than before because of the "cut-all" option that Jagex introduced. This made cutting the fish take slightly longer. However, using feathers or bait to catch the fish will increase the experience per hour considerably.
Although different in appearance in the inventory, the Barbarian Rod is no different in appearance to any other fishing rod in the Fishing animation.
