I run a macro with 3 fishers, they fish until they pull a monster then swap to energy bolt turrets until the monster is dead.
Serpents/Deep Sea Serpents/Kraken/Shipwreck Kraken are all very very weak to energy bolt. With archery you're going to go through a ton of arrows, some miss, some don't hit as hard as others, etc. However, if you eventually plan to run 2+ fishers then magery is your best bet. If you use UORudder (google it) then it should never be an issue catching up with a runaway Kraken. The only time that I see peacemaking as useful is when you fish up a Shipwreck Kraken because they tend to swim away very fast when they are low on health. However, any type of bard skill is kinda useless out there as nothing is really that difficult to kill.
If you plan to have 1 fisher then I agree that archery is the way to go, unless you can find a reptile slayer in a melee weapon.
