I saw a hundred or so in my local river before opening day.
Was hoping to whitebait the full moon but my local rivers are all in flood, it might just be clear enough tomorrow for a spotting but blind techniques are probably required. I am not a fan of blind fishing so would wait a couple more days.
Checked out the Pelorus today, because it clears a lot quicker then the east coast rivers. Clarity was good (3-4m) but saw no whitebait. Had a look in the Kaituna for the same outcome. Never seen anyone white baiting the Pelorus, but seen a few white baiting the Kaituna. I have the impression neither are overly productive. These so many tiny streams in the sounds which whitebait can enter.
