The term '''secondary set''' is used when describing [[fish]] patterns.

A fish pattern has 2 interacting sets of [[constraint]]s. These are usually [[row]]s or [[column]]s, but modern fish variations also use [[box]]es. The 2 sets are equal in size. One of the sets is the [[defining set]] and the other is the '''secondary set'''.

In a fish pattern, the '''defining set''' of constraints only has candidates for the selected [[digit]] which are located in one of the constraints belonging to the '''secondary set'''. The secondary set has surplus candidates which are not located inside the defining set. These surplus candidates can be eliminated.
