Detailed Walkthrough
Slaughterfish Problem
Aelwin Merowald can be found walking around his house in Weye after about 7 or 8 in the morning. Talk to him and go through his dialogue in order to receive a quest to kill twelve Rumare Slaughterfish. When talking to him, it is advisable to not select the option to laugh at him, since laughing will decrease his disposition towards you by 60 points and end the conversation. If you lower his disposition below 20, he will not even start a conversation with you; a Charm spell will be necessary to get his disposition over 20 and receive the quest.

Gone Fishing
Follow the quest marker to find and kill each fish. It may be necessary to search the area around where the marker points because it is not always accurate. The Detect Life spell is useful for locating the fish. It is also much easier to fish during the day.

Once you've collected the scales from the first fish, the marker should point to the next one (there might be a short delay). If the marker doesn't update, try hitting the fish's corpse or leaving and waiting elsewhere for a few hours. Continue this until you have all twelve scales. The quest isn't timed and the fish don't move, so you do not have to complete it all at once.

Talk to Aelwin again and he will give you a unique ring called the Jewel of the Rumare, which is enchanted with Water Breathing and Fortify Athletics 4 points, a rather nice reward for such a simple task.

Retirement Savings
Aelwin mentions that the fish scales will be sold to an alchemist and the money made will contribute to his savings for his retirement. If you are the thieving type, select the Where are your savings? dialogue option. If you increase his disposition to at least 70, he'll mention that his savings are locked in a box in his house and he has the key. After Aelwin tells you this, you can pick his pocket for the key or kill him and take it. The chest is located to the left of the fireplace in his house, though there is only a small amount of gold in the chest. Note that the key will not appear in his inventory if you do not successfully ask him about his savings.

Notes
The following three Journal discrepancies occur:
:* Although the quest journal says that the Weye settlement is southwest of the Imperial City, it is actually due west.
:* The quest journal states that Aelwin is getting too old, therefore you need to do the legwork for him. Aelwin however says the reason he can't get the scales is because a slaughterfish injured his leg.
:* The journal (and Aelwin) mentions that the Rumare Slaughterfish is a special breed that can only be found in Lake Rumare, directly north of Weye. It is not clear whether "directly north of Weye" refers to the location of Lake Rumare or the location of the slaughterfish, but in either case the description is inaccurate. Lake Rumare lies east of Weye, and the slaughterfish can actually be found to the north, east, and south of Weye.
Aelwin is located very close to the wilderness, so he might wander off and become wolf food. If this happens, PC users can resurrect him using the console, using the command  , but Xbox or PS3 players will be unable to complete the quest.
The only way to get the Jewel of the Rumare is if Aelwin hands it to you; the ring will not be on his corpse if you kill him.
It is advisable not to kill the fish before making the quest active, as it may lead to the marker indefinitely pointing to the first fish.

Bugs
 
Using the Console to add the scales to your inventory will not make the quest continue. However, if the scales are put into the body of a quest-spawned fish and then picked up it may update the quest properly.
Using the   command in the Console on the corpse of a previous fish and then killing it again can be used to advance the quest if the player has already killed one and the corpse is still present.
Alternatively, simply search the lake for other Rumare Slaughterfish. Unfortunately, this can be a slow and frustrating business. However, it is possible to use the console to spawn new fish directly in front of you:  player.placeatme   , where     ranges from   through   (see Rumare Slaughterfish for details).
 
The same notes about the previous bug also apply here.
An area-of-effect Command spell can be used to relocate the fish, or an area attack spell used to kill it, if it's within range; but you may have to reload an earlier save.
 
 
  You can remove the Quest Item status of the scales yourself with the following command:
