Dolphin kicking drills, with or without fins, will work your abs. You can drill at a higher tempo than regular swimming and exaggerate the movements as much as you wish.
I agree that holding a "toned" position while doing backstroke or crawl can, in effect, be like an isometric exercise. I have also been giving attention to that area recently while doing the crawl.
Maybe try the Pilates "plank" exercise. Try hold it for 30-60s. http://www.monkeysee.com/play/383-pi...thigh-exercise
