I've also had 2 get away mid-fight because dawn happened and they just slithered off rather than finish fighting me.
You can only (as far as I know) make the deep fish bait with their trophies... which you have to kill them to find.
If anyone knows a way (besides sailing around at night and/or storm - because I do that) to make them spawn or find them more often, I'd be happy for the advice.

You can find an island close to the ocean biome on your map. Raise the land as far out as you can, and then build a dock with iron beams out into the ocean. Now just run back and forth on the dock. Every time you cross into the ocean biome you have a chance to trigger a spawn. When one appears, harpoon it and drag it onto the island.
