In a large resealable food storage bag, combine salmon with citrus juices. Allow to marinate in the refrigerator for a minimum of 4 hours and up to 8, turning the bag a couple times to mix.
Drain the salmon and discard the liquid. Place the fish in a large bowl and add the avocado, mango, tomato, onion, jalapeno, olive oil, cilantro and salt. Serve on corn tortillas with lime wedges for squirting on top.
