Not exactly deep sea fishing but Phoenix Dive in Cala Compte had a wonderful snorkeling trip to Es Vedra. It was around 30 Euro each but filled up quick because the boat was small. It was great fun because of how few people were on the boat, and the captain took us around Es Vedra and then to Atlantis and Cala Tarida for snorkeling and swimming; from 2 PM - 6 PM. In Atlantis we were able to feed the blue fish (I was hoping one of them would eat the jellyfish!). The view underwater was stunning but quite deep (I love heights but am scared of depths, so my time in the water was minimal), and then when I came out of the water I noticed Erick Morillo and friends were laughing at us from their Sea Doo boat. It's a German diving company that caters mostly to the residents at the Delfin Playa (I was the only English speaker aside from the captain), but the trip was a lot of fun. The closest we came to fishing were the cookies we threw in the water to attract schools of fish in Atlantis, and I did see a flying fish on the way to Es Vedra. The goats are fat on Es Vedra - we saw tons of them feeding like crazy. Didn't see any bats, though.
