Mechanical Blowfish

This quest is part of the first secret fish achievement, Secret Fish of Mechagon.

The fish:
All of the fish for part 1 of this series can be caught within Mechagon. The catch rates are quite low (~1%) so expect to spend a fair amount of time fishing. You do not need max Kul'tiran/Zanadalari fishing. Once caught you'll auto-accept a quest to show the fish to [npc=151462], who is also on the island. Should the quest fail to auto-accept for any reason you can simply right click the fish from your inventory to start it.

Note: Below are confirmed locations and are likely not the only locations where they can be caught.

The coastal fish:
These 3 fish can be caught near Danielle, though its likely they can be caught anywhere along the coast of the island.

1. [item=167661]
2. [item=167662]
3. [item=167655]

The area specific fish:
Each of these fish can only be caught within a specific area of the island.
I've created a map to show their locations: https://i.imgur.com/Hr3Q1ij.png

Alternatively here are the X,Y coordinates for each.
4. [item=167663] - 47, 37
5. [item=167654] - 79, 49
6. [item=167656] - 65, 32
7. [item=167657] - 59, 24
8. [item=167660] - 65, 51
9. [item=167659] - 83, 72
10. [item=167658] - 25, 77

The goggles:
Once you've caught all 10 and shown them to Danielle she'll sell you the [item=167698].
You can now move on to part 2 of this series, Secret Fish and Where to Find Them!

I have also written a guide for part 2 which can be found here in the comments section of the achievement page.

Happy fishing! :)
