Dead 6.5 lb Softshell turtle

I've been catching several softshell turtles on the trotline - most on magic bait (I think the small amount of magic bait on the hook - 'hides' the hook better than a bream which the turtles pulls off the hook. Couple days ago got 2 in one morning (estimated - they were 5 lb or more) - then today - I had to bring this one to shore (couldn't get off hook) - so I checked weight = 6 lb 9oz

Also got a 1 lb 15oz channel catfish on magic bait off the side of my fishing pier - sad to say it died so I had to clean it before breakfast :(
