Disruptive selection is a term used to describe population genetic changes that simultaneously favor individuals at both ends of the distribution. When disruptive selection operates, individuals at the extremes contribute more offspring than those with intermediate characteristics, producing two peaks in the distribution on a graph.
In the excerpt shown in the question, long-gill-striped and gill-striped fish were favored by the selection process than intermediate-length striped fish. For this reason we can conclude that a disruptive selection was taking place.
