UO Second Age

Once I have an MIB on my fisherman, what does it fish up? If a chest, do i need lockpicking to unlock it? I was wanting to play a template of:

Arch
Tact
Anat
Heal
Magery
Eval
Fish

Just something fun to pass the time and bring me back to the days of being a pirate.

no lock picking required, just brings up varoius shipwreck junk randomly and then a chest
