I find the fisherman to be a fun solo char. A very popular fishing template would be something like:
Fishing
Cooking (complimentary, fishsteaks and all)
Archery or magery ( to kill serpents later)
Tactics or Eval (for the damage increase)
then depending on the your template Mage route, or Fighter route, round your skills out with Med and maybe FOcus or someother fun skills, or Chiv, Focus and maybe Anat and Healing for a fighter type.
You can set up UO assits macros to save on the carpel tunnel and just rake in the fish and footware. Let the fish stack up on your deck and once in a while cut em into fishsteaks.
Make sure you follow the training guide, which was something like fish from shore till about 36 or so, then head for semi deep water, server lines in the ocean are best, up to about 60, then plain old deep water. I am sure I am off on the numbers, it has been a long time since I built a fisher.
But, Have fun!
