For most swimming fish it is best to have the plunger drawn back half way. When you place the orifice close to the fish slowly push the plunger in, causing a current that most fish will naturally swim into. Then draw the plunger back to trap the target animal.Have a mesh game bag handy to put your collected catch in.
