No fish at all or no skill ups at all? For skills one of two strategies will work best and a combination of both is probably the best plan of attack. Targeting fish you don't normally target and using the latest rig unlocked is strategy A. Strategy B is targeting fish with a high bite rate so you have more opportunities to get a skill up from a fish. So the best thing to do is target fish with high bite rate, using the latest unlocked rig that you do not normally target. If you do indeed mean no fish at all, can I have your username so I can have a look?
