Once the fishing urn is full, it becomes a Fishing urn (full) and can be teleported to Ernie for 500 Fishing experience. If catching two fish at once with high Agility, the urn only fills with xp from the first catch. The second does not count. However, harpooning swordfish while wearing the swordfish gloves will result in filling the urn faster. Note: You can only have 10 filled fishing urns ready for teleporting. If you have 10 the next urn will not get filled until you teleport at least one urn away. Then you can fill up to another 10 urns.
