Every basic fish pattern (above 1-Wing) has at least two vertices in every row/column of the fish. In the Swordfish below, there are at least two asterisks (*) in each row/column for the Swordfish. Since all of the extra cells (#) in the Base Sectors [r249] are contained in [b3], then this pattern qualifies as a finned Swordfish ... and all eliminations are restricted to [b3].

If I perform a (definitely invalid) modification to this pattern, then I get a Sashimi Swordfish because there is now only one cell with an asterisk (*) in [c8] from the Swordfish pattern.

Some people call this a finned Sashimi Swordfish because of cell [r2c9], but the qualifier term
finned isn't appropriate -- even though some of us include it anyway.
Bottom Line: I should have kept my mouth shut and let those who are much more knowledgeable answer your question.
