@ShosaSosa Don't use it until you have a fish on the line. It is not a debuff remover, it is an alternate Hook action which ignores the debuff.

At level 70, can catch this with http://xivdb.com/item/12704/stonefly+nymph, http://xivdb.com/action/4106/patience+ii, and http://xivdb.com/action/4103/powerful+hookset on Medium tug.
Can be used for Zhloe Aliapoh's custom deliveries, minimum 175 collectability. For max scrip rewards, aim for 330 collectability.
Caught an HQ version of this fish while trying to get http://xivdb.com/item/20019/ala+mhigan+ribbon. Like the http://xivdb.com/item/20079/gigant+bass, caught it with http://xivdb.com/item/20675/stonefly+larva (yellow scrip bait), http://xivdb.com/action/4106/patience+ii, and http://xivdb.com/action/4103/powerful+hookset on Medium Tug. Mooching not needed if done this way.
Caught HQ version of this while trying to get http://xivdb.com/item/20019/ala+mhigan+ribbon. Used http://xivdb.com/item/20675/stonefly+larva (yellow scrip bait), http://xivdb.com/action/4106/patience+ii, and http://xivdb.com/action/4103/powerful+hookset on Medium Tug.
Since this fish isn't used in any recipes (only desynth) and http://xivdb.com/item/20675/stonefly+larva uses yellow scrips, consider using http://xivdb.com/action/300/release to avoid getting more of this fish.
Was trying to catch https://xivdb.com/item/20044/tao+bitterling for red scrip turn in, but ended up catching 4 HQ https://xivdb.com/item/20134/bowfish in a row instead with little effort. Used a https://xivdb.com/item/20619/suspending+minnow (red scrip bait) as bait and used https://xivdb.com/action/4102/patience + http://xivdb.com/action/4103/powerful+hookset on strong tugs. Location: x: 20, y: 7.
I have used https://xivdb.com/item/20615/midge+larva with http://xivdb.com/action/4106/patience+ii and http://xivdb.com/action/4103/powerful+hookset before to catch https://xivdb.com/item/20134/bowfish as culfin suggested, but the bite rate is very, very low, maybe 1-2 catches at best with each http://xivdb.com/action/4106/patience+ii "period". It works, but it's incredibly frustrating.
Need 3 for GC turn in.

While this fish has an incredibly rare window, it's actually quite easy to catch. It requires that you first mooch a http://xivdb.com/item/12722/blueclaw+shrimp which is super easy since there are no other possible fish to catch at that time except for a really rare http://xivdb.com/item/14211/amber+salamander with a big fish tug. When using http://xivdb.com/action/4102/patience, use http://xivdb.com/action/4179/precision+hookset for the Blueclaw Shrimp, and then http://xivdb.com/action/4103/powerful+hookset for the Thunderscale.
Note the weather transition. That, plus the relatively short time window, makes this fish window quite rare, (less than 1% uptime). Make sure to use a proper big fish tracker in order to track this window properly.

To catch this fish, you must first catch a High Quality http://xivdb.com/item/12753/sky+faerie. It has a relatively fast hook time. If using http://xivdb.com/action/4102/patience, you will need to use http://xivdb.com/action/4179/precision+hookset. Then use http://xivdb.com/action/297/mooch to snag the Basking Shark. It's a pretty standard wait time for a legendary fish, with the normal legendary fish tug. http://xivdb.com/action/4103/powerful+hookset should be the one to use if necessary, although I was able to catch this fish without Patience on, so I cannot confirm for sure.
The specific weather transition window is quite rare, so use an outside source for proper weather tracking such as http://www.garlandtools.org/ffxivfisher/
