Decided to finishing off my fisherman from 96 to GM. Found out there are two new things when you're out fishing. One, if you're moving slow forward or just forward, sometimes I get the message:"You must be closer to the water in order to fish."..or something like that. Also, there is an item that can get tangled on your line which results in you pulling up some ' Delicate Scales.' These I think are imbuing ingredients and are stack-able. Their type is: UDHB.
Edit: The message for getting the scales is, "As you reel in, you notice that there is something odd tangled in the line." The scales go directly to your backpack.
