The Skipjacks are a member of the Herring family. Which also enclude Treadfin shad, Gizzard shad, Alabama shad, and Skipjack herring.
Skipjack are rarely ever cought in a cast net. mostly rod and reel only.
There is a lot of information about catching Skipjacks on the site. Try some searches and you will find something.
