Still learning about these, and happy about that.
Dipped my toe into the water in the reports section, but an curious to share views on water temp and where jacks are in a system.
I reckon if it gets too cold in the estuaries, and they are big enough, they might move offshore.
Likewise, if it gets so hot the dissolved oxygen level goes down, they don't feed.
But that doesn't explain their comings and goings, ok, mostly goings in the systems I fish - it'd be great to hear your views on when they move out of estuaries and why, and also when they move within estuaries
