How would one make a Stat Block for 5e for a Cave Fisher?

Ok, I played alot of ADOM recently, and these spider-like cave fishers were mentioned in many of R. A. Salvatore's books. But the real question...

How would a stat block for 5e portray a cave fisher? I am running an Out of the Abyss campaign, and I want to replace some monsters in the Underdark with these lobsters.

There's a cave fisher in Fifth Edition Foes from Necromancer Games, for what it's worth. I can't give you the stats, obviously, but it's CR 2.

Lazy mode:

Take Giant Spider as a base, remove poison, refluff web spit as the cave fisher's filament thingy, and also add an ability to reel in any Medium or smaller creature it successfully hit with the "web" thingy up to 15 feet each turn as an action.

Possibly as an opposed strength check.
