About the Fishing in Alterac Valley: http://www.elsanglin.com/fish/alterac_valley.html

So it was removed many versions ago because players would fish instead of fight.

INSERT INTO fishing_loot_template (`entry`, `item`, `ChanceOrQuestChance`, `groupid`, `mincountOrRef`, `maxcount`) VALUES (2597, 13889, 10, 0, 1, 1);
INSERT INTO skill_fishing_base_level (2597, 330);

This will remove the console spam for errors AND will not deliver the fish that was fished there in patch 2.1 or below. I put 0% chance.
