He has migrated from standing around in the Stormwind Canals to Northrend, after reaching 330 Fishing skill. His skill is actually 450 buffed up with [Seth’s Graphite Fishing Pole] & [Sharpened Fish Hook]. The next step after wondering to Northrend is asking, “Where exactly should I fish.. and where can I fish?!” That can be answered by one of my favorite WoW websites, El’s Extreme Anglin’ Fishing Guide.
El’s Extreme Anglin’ will tell you that most of the Northrend (the southern half) only requires 380 skill to cast and 480 to avoid “Get Aways”. This means that at skill 450, some fish still eluded my poor Death Knight but not enough to make you fish worthless fish in Outland or anywhere else. Some misses are worth it when you’re getting good fish you can actually use.
Grizzly Hills was the chosen fishing hole because of the [Glacial Salmon] Schools of fish that spawn in the zone. My warlock uses these fish in cooking for the spell power food [Firecracker Salmon]. Some other notable fish caught in this zone are the [Bonescale Snapper] and [Fangtooth Herring] which can both be cooked and sold on the Auction House or put in the Guild Bank.
One of the little perks from fishing is catching the parasitical [Pygmy Suckerfish]. Since Patch 3.0.8, the drop rate for these has seemed to double! The great part is that you catch them along with whatever fish would have normally been hooked.
