as you can see the NPC page for the fishbot is wrong, it does begin the quest above, as well as the others

Let the Tournament Begin!
Schools of Tastyfish:
As soon as the tournament begins, ""School of Tastyfish"" nodes will spawn all along the coast of Stranglethorn Vale. Yes, the entire coast is in-play with the exception of booty bay itself and Juergo isle (the large one on the east side of STV). The nodes look like small whirlpools, 2-3 yards in diameter, complete with silvery fish flickering in and out. They are visible from a good distance as a shimmering spot in the water.

Spawn Locations:
The locations of the nodes are fixed. That is, a node is either there or not there, but the locations do not change. You'll find that there is a spawn location approximately every 100-200 yards or so along the coast, so there are many pools forming constantly. The best way to learn them is to participate in the tournament - you'll be lost the first time, but you'll learn them more as you continue to participate each week.

How to Catch the Elusive Tastyfish:
In order to catch Tastyfish, you must cast your bobber inside one of the fishing nodes. To be on the safe side, ensure that your bobber is at least partially touching the edge of the swirling waters. Ideally, cast it right into the center so you don't have to worry. If you miss, re-cast again. There is no way to guarantee that your bobber will land in the right place. Learn how far back to stand so that the average-distance cast will at least have a chance to intersect the pool itself (stand too close and you'll always overcast; stand too far and your bobber will never make it out to the pool).

Once your bobber lands in a good position, just wait and fish as normal. You'll reel in either some Stranglekelp, a Tastyfish, very occasionally a rare fish (very rare) or something else (anything you could normally catch in these waters goes here).

Node Mechanics:
It seems that the nodes are quantity based, similar to other resource nodes. There are approximately 2 to 6 Tastyfish per node. Once they've all been caught, the node will disappear.

Multiple people can and will fish in a single node. Multiple bobbers will clutter the whirlpool and make it hard to click and mean that the hole will be fished out and dissapear that much faster. Generally, that means that you want to skip that hole and find an empty one...I only fish in holes that other people are in if I am certain or at least very sure they just got there, and then I wont get more than 1-2 fish before i mount up and find the next one to stay ahead of the competion thats fishing that node.

Changing Nodes:
As soon as a node despawns, immediately mount (or hit your speed boost) and proceed to the next most probable location for a spawn. This is something you will learn from experience. If you know a nearby pool despawned 5-10 minutes ago, head there now, as this seems to be the approximate time between respawns.
(don't swim unless its unavoidable, you have azure silk belt, swimspeed pots, aquatic form, or already have the hook of the master angler).

Things to Watch Out for:
There are quite a few nasties along the STV coast if you are around the lvl 40 area. On the southwest side are the highest level mobs in the area, namely varieties of Naga. These are particularly annoying because they wander far (even into the ocean) and have a large aggro radius, are social, and like to net you.

The rest of the west coast is (for the most part) inhabited by Crocolisks and Raptors, of which the Crocolisks are by far the worst since they (like the Naga) will sometimes enter the water where you are.

The east coast of Stranglethorn, by comparison, is great. The ruins can be a problem if you are below level 40; levels 40 and up will generally be able to walk past without a problem. The one thing you must watch out for, regardless of your level, is the unique level 47+ Elite Giant Gorlash. He roams the shore slowly and is easily avoided, but there are always a disturbing number of skeletons near him when you pass by.

And last but not least, if you are on a PvP server, watch out for the enemy. you will hate your life as this event is commonly referred to on PvP servers as the ""Stranglethorn Vale Fishing Gankfest"".

The Tournament Completed
How Long This Takes:
Normally the Winner for the week has caught and turned in their fish in less than 30 minutes...about the longest I have seen the contest go before a winner is about 42 minutes. the last two times i won in 24 and 29 minutes.

Winning:
I have won 6 times total now over 4 characters (3 of which no longer exist/belong to me) The second you hit 40, hearth back to Booty Bay, use your speed boost if you've got it, and talk to Riggle Bassbait to win the tournament. You do not actually win until you select your reward and hit complete, so do this fast as there is more than likely going to be someone else with 40 fish already as well trying to turn them in and win. A /yell will be sent to all of STV informing the zone that you are the victor of the contest for the week. W00t for j00, Master Angler!

Not Winning:
Most likely you will not win, there is alot of competition, and there is only one winner each week per server. If this is the case, you can stop fishing when you see the /yell, or you can continue to fish the nodes. The mechanics stay the same if you keep going. You can continue to catch Tastyfish and even rare fish for as long as the tournament continues. Once the contest is over and the nodes despawn for the week at 16:00 (4:00pm local server time) , you should return to Booty Bay and turn in what you've got for what prizes you can. The NPC's in booty bay associated with this will stay for one more hour til 17:00 (5pm) to turn in any of the tastyfish or rarefish that you caught (This means you can actually fish the full two hours until the yell says the tastyfish have left for the week and not have to stop early to turn in)

Sorry, No Cheating:
Blizzard has it covered when it comes to the various shady tactics that we all, of course, immediately think of and wish we could explot:

1. Tastyfish are eternally Soulbound, so you cannot trade them.
2. They are limited duration items (duration 4 hours). No saving them to turn in first thing next week

So now you know all you need to know to win the Weekly Sunday Stranglethorn Vale Fishing Extravaganza fishing torunament.

Fishing in General.
At Fishing Lvl 525 or higher, you will stop seeing ""your fish got away!"" messages no matter where you go, including the 3 fly-to only lakes in Terrokar Forest which have the highest fishing requirement and best fished items in the game.
427 is the highest fishing skill you can have unlured (same as above, but with the +2 fishing skill to glove enchant as well), which makes the in-game cap for fishing 527 with an aquadynamic fish attractor.

How to get 527 Fishing

Leveling Fishing:
Fishing in even the lowest lvl water can and will lvl you fishing, and even in the lowest of waters like the pond in org, it wil take no more than 14 successful casts to gain a skill lvl.
Fishing 1-75 - Learned from trainer.
Fishing 75-150 - Learned from trainer
Fishing 150-225 - You will need to get and read the https://vanillawowdb.com/?item=16083 Expert Fishing - The Bass and You Book that you can buy from https://vanillawowdb.com/?npc=2626 Old Man Heming in Booty Bay on the Lowest level of the town.
Fishing 225-300 - At lvl 225 you will Have to go to the islands in Dustwallow Marsh and Find https://vanillawowdb.com/?npc=12919 Nat Pagle to get a https://vanillawowdb.com/?quest=6607 quest from him to catch 4 rare fish, one for The savage coast in STV, one from the Verdantis River in Feralas, one from the norther Sartheris Strand in Desolace (there are actually two stretches of coast labled as Sartheris strand, you need the northern one that is near the sunken boats), and one from the coastline in Swamp of Sorrows. Upon Completion of this quest, Nat Pagle will give you Master Fishing skill raising your cap to 300
Fishing 300-375 - You will need to go get your hands on the Artisan Fishing Book, https://vanillawowdb.com/?item=27532 Master Fishing - The Art of Angling, which is obtained from the fisherman, https://vanillawowdb.com/?npc=18911 Juno Dufrain, at the Cenarion Expedition in Zangarmarsh in the Outlands, just on the bank of the lake.

https://vanillawowdb.com/?item=27388 Mr. Pinchy:
In the 3 fly-to only lakes in Terrokar Forest, there are a total of 17 Highland Mixed School fishing nodes (3 in Lake Jorune above Stonebreaker Point, 4 in Lake Ere'Noru above Allerian Stronghold, and 10 in the Blackwind Lake/Skettis area.) You will need to have about 480 or more fishing to reliably catch the fish in these lakes...being Furious Crawdads, Goldenscale Vendorfish (that vendor for 6g per! ), Golden Darters, crates, scrollcases, and possibly Mr. Pinchy.

(As a side note, Furious crawdads only come from those Highland Mixed Schools, which are used in cooking Spicy crawdad, Which gives you 30 stam and 20 spirit for 30 minutes if you spend at least 10 seconds eating)

Just like there the rare fish in STV during the contest, there is a very small chance that you can catch Mr. Pinchy, a rare Crawdad that will have 3 wishes (charges) that give a random effect/item with a 48 hour cooldown from those Highland mixed pools. Mr. Pinchy's drop rate is approximatly 0.2% which averages to about 1 in 500 successful casts. So be prepared to spend alot of time trying to get h im.

If/When you get Mr. Pinchy there are 5 effects of the wishes. These are:
-https://vanillawowdb.com/?item=27446 Mr. Pinchy's Gift, A gift wraped package that will have 4-5 Super Healing, and 4-5 Super Mana potions in it. (seems to be the most common result of the wishes)
-Summon https://vanillawowdb.com/?npc=18846 Furious Mr. Pinchy, lvl 70 Non-elite that will attack you and party.
-https://vanillawowdb.com/?npc=18845 Benevolent Mr. Pinchy, Summons a lvl 70 guardian to assist you in combat.
-https://vanillawowdb.com/?spell=33053 Mr. Pinchy's Blessing, a 2 Hour +500hp buff that lasts even through death.
-https://vanillawowdb.com/?item=27445 Magical Crawdad Box, The only permanent, non-consumable reward, a uber-rare non-combat pet (normal white quality, but uber rare because you have to catch Mr. Pinchy in the first place to get it, and then be lucky enough to get him to give you the pet after that.

After using the 3rd Charge/wish https://vanillawowdb.com/?item=27388 Mr. Pinchy will dissapear from you inventory having been consumed. You will have to catch Mr. Pinchy again in order to get another 3 wishes/chances to get what you are looking for, which for most people is the Magical Crawdad Box.

Summary:
So you are all set to go win the tournament. By far the hardest parts are memorizing where the nodes spawn and learning where to stand so that your bobber has the best chance to land in the swirling Tastyfish whirlpool. Watch out for aggro, run swiftly, fish deeply.

P.S. If you want to see the ""fish form"" of the trinket or see the swim speed increase in person, and/or see the pole, just let me know.
