Jawless Skulker

This quest is one of the dailies that becomes available via [npc=79892] after unlocking the fishing shack by completing Looking For Help at level 94 in your garrison.

Head over to Gorgrond and fish up 5x Enormous Jawless Skulker, 10x Jawless Skulker, or 20x Small Jawless Skulker from Jawless Skulker schools, or open waters ([item=110274] helps with open water if you got 'em). Once you get enough, simply right-click the respective stacks and you'll loot some eggs along with the fish itself.

Tailthrasher Basin (45.7, 90.7) is a quick and easy spot for Horde players as it's just to the left of the Bastion Rise flight path and usually contains a skulker school.

No Need to fly around each day fishing for these guys. If you keep a stock of them; whether a few stacks of: 5 Enormous, 10 Regular, or 20 Small; as long as you filet them during the daily you will get the eggs dropped from them.
This leads to the next plus, if you purchase the fish in the AH or get some as a gift from a friend or guildmate, you will get the eggs from fileting them too. As long as you have the type of fish for your daily and filet it during the daily you will be able to complete your quest.
If you are working on Draenor Angler don’t just filet them all; hold on to them for your dailies.

I had more luck fishing these up in inland bodies of water, not open water. I fished up one of these in about 30 casts in the ocean, moved to a small inland pond in gorgrond where I immediately fished up two in a row.
