At times the news seems insurmountable, searching through the Internet for fish related topics yields a flood of extinct, dying, and on-the-brink stories – interspersed with articles on how to cook what’s left.

Like most fishermen I don’t eat as much as I fish – but there’s times when I get the feeling I should eat more fish just to get my fair share of the condemned.

Instead let’s focus on what’s doing just fine, which fish are enjoying explosive growth and how advanced mathematics and supercomputers can assist you in gear selection, what flies to stock heavily, and what the future gamefish scene will look like…

Both Europe and North America are experiencing a “changing of the guard” where former indigenous species are giving ground to the Next Great Freshwater Gamefish.

The green triangles show known captures, brick red describes the areas with the highest chance of supporting a significant fishery (where they’re headed next), and as the colors fade to white – where we can expect a lesser presence.

It’s comforting to know Mother Nature will repopulate all those salmon and steelhead streams once we’ve finished cooking the last of the holdout fish. When the pristine gives ground, swarms of fish will replace trout – and the guides in Montana have little to fear, the entire Northwest is “brick red” and the Yellowstone drainage will continue as a trophy fishery long after “Old Faithful” is firing methane blanks…

Toss those silly five weights as you’ve no need of them. Watersheds that supported 14″ fish in quantity will be supporting as many fish in the 20 lb class – so start dusting off the seven’s and eight weights. Trout iron will straighten – so while you’re at it, stock up of #8’s, #6’s and above – and extra stout, in stainless and black nickel …

It’s gold – like the scarce and rarified Golden Trout, grows to enormous size like Taimen, and is a muscular brute in both fast water and slack, akin to the Mahseer – only much more plentiful and perfectly suited to most of the globe.

Behold the computer model of the spread of the next great freshwater gamefish, the Golden Bullet of the Weed Water, the Common Carp.

A little garlic and a dab of dill … but save room for the Grass Carp (the entire east coast), the Black Carp (the entire South), and our pal the Silver Carp … busy claiming whichever waterway it feels like.

… plenty for everyone, and the depth of color suggests they’re destined for naturalized citizenship, losing that silly invasive label once they outnumber everything else.
