Because this solving method isn't embodied in SE, I'd like to knowing what it is.
Does it have example?

N*N fish ("seafood") comes in a variety of sizes. X-wings are "fish" defined by all occurances of a given candidate in two rows or columns, Swordfish consist of 3, Jellyfish of 4, and Squirmbags are defined by 5 rows are columns. There are a bunch of examples here. In general, given a Squirmbag, there are smaller fish eliminations which can also be performed. This is not true of the ones in this post since they are more exotic than the basic "Franken" Squirmbags (see here for a summary of these). In some cases a contraint subset consisting of rows and boxes or columns and boses can be found which is smaller.

What about 6x6, 7x7, 8x8, 9x9?

From the thread you mentioned vidarino regards 6x6 as a "whale", 7x7 as a "leviathan", while tarek has these suggestions:

As for the naming, I suggest:

n=5, Starfish instead of Squirmbag
n=6, Seksfish (You can't object on this one Vidar)
n=7 Dogfish (7 letters)
n=8 Octupus
n=9 Enniafish
n=10 Hammerhead (10 letters) or Whaleshark

Of course only finned version of these big fishes are useful, because for "normal fish" exceeding 4x4 in size we'll just deal with their duals...
