I won’t say definitely not, but it’s unlikely. There’s still plenty of fish in the seaway to be caught, I still get reports from others up there and not much has changed. Lots of GT’s, Bigeyes, Tailor, Jewies, Kingies even some squire kicking around at the moment.
Everything you need to know to consistently catch fish in the seaway is written on the website right now. The only extra stuff I can add(and will do in time) is fine tuning techniques and giving you a greater understanding of fish behaviour.
Planning your trip is key to success. Knowing what the tide is doing is critical, as is using the right technique at the right time.
