A '''Turbot Fish''' is a [[single-digit]] [[solving technique]] that uses a [[loop]] of odd length. The minimum length is 5, forming a fish-shaped pattern that gave the technique its name. Longer loops are possible, but they are better known as [[Fishy Cycle]]s.

Here is an example of a Turbot Fish:
.-------.-------.-------.
| . | . | . | . | . . . |
| . X . | . X . | . . . |
| . | . | . | . | . . . |
:-------+-------+-------:
| . | . | . | . | . . . |
| . X . | . | * | . . . |
| . | . | . X . | . . . |
:-------+-------+-------:
| . | . | . | . | . . . |
| . | . | . | . | . . . |
| . | . | . | . | . . . |
'-------'-------'-------'
The candidates in [[column]]s 2 and 5 are strongly linked. The pattern causes either '''r5c2''' or '''r6c5''' to be true. Since '''r5c6''' can see both these candidates, it can be eliminated.

This pattern is also known as [[Skyscraper]].

The following pattern is also a Turbot Fish:
.-------.-------.-------.
| . . . | . - . | . . . |
| . * . | . X . | . . . |
| . . . | . - . | . . . |
:-------+-------+-------:
| . . . | . - . | . . . |
| - X - | - - X | - - - |
| . . . | . X . | . . . |
:-------+-------+-------:
| . . . | . - . | . . . |
| . . . | . - . | . . . |
| . . . | . - . | . . . |
'-------'-------'-------'
The candidates in row 5 and column 5 are strongly linked. The pattern causes either '''r5c2''' or '''r2c5''' to be true. Since '''r2c2''' can see both these candidates, it can be eliminated.

This pattern is also known as [[2-String Kite]].
